Tabletop Exercise - Essay Example On 3rd May 1999, a series of tornadoes struck Oklahoma City, which are some of the most expensive in the history of the United States. They caused a damage of more than 1 billion dollars and destroyed more than 2500 structures. In less than 21 hours, a total of 21 tornadoes, swept though the states of Kansas and Oklahoma. There were as many as four tornadoes at one point reported on the ground simultaneously. The strongest and most destructive tornado was rated on the Fujita tornado scale as having a maximum F-5 and tracked for about one and a half hours through southern Oklahoma City from Chickasha and the neighborhoods of Newcastle, Bridge Creek, Del City, Midwest City, and Moore. There are various drills that should be adhered to in case a tornado strikes. However, there is need for the development of a policy on the appropriate standard procedure to be applied at local educational facilities in the vent of such a disaster. There is need for members of the administration of these institutions to be aware of their roles during tornadoes and similar disasters as they are not fully aware, and their skills have not been enhanced to handle such situations. This table top exercise experiment will offer an opportunity to members of the university of Oklahoma college administration and a group of students to learn the launching and use of incidence command system. The exercise should further identify the improvements and preparedness the institution needs, and provide a contribution to the emergency operation plans.

Estimate the Market Size - Case Study Example Noarlunga centre is an attractive place due to the reason that it covers the residential, commercial and parkland region. Moreover, the recent growth and development is another feature that makes it an eye-catching place (City of Onkaparinga, 2011). Stage lives including the living theatre, concert and visual arts are one of the product types available at Hopgood Theatre. According to the statistics, it has come to conclusion that adults that age 15 years and above living in South Australia are the main stakeholders that have an interest in arts and theatre. In addition, approximately 38 percent of the people that makes up more than 2.5 million visitors attend cultural venues and events on yearly basis. Moreover, the people are also keen to come under involvement in cultural activities, which depicts the figure of over 225,000 people. Slightly over 25 percent of the children between 5 to 14 years are also involved in cultural activities (Australian Government, 2011). ... A higher proportion that is approximately 99 percent of juvenile of the age group of 15 to 17 years in SA attended cultural venues and events, compared to the other age groups surveyed (ABS, 2007). According to the statistics, the rate of market is increasing due to the reason that the average income as compared to the previous years has seen an inclination in the trend. In addition, the primary cause for the increase in income was the increasing demand of the labor and employment rate also increased with the launching of projects. Moreover, the importance and emphasis on education has also experienced a raise and enhancement over the years as the increased number of visitors on the website proves this fact. While looking at the other end of the continuum, the average spending time of people on the culture and recreation or the leisure activities has come across a declination towards the trend over the past few years. This downfall has added to the reason of the decreasing market.

Cybersecurity Coursework Example | Topics and Well Written Essays - 1000 words

Cybersecurity - Coursework Example The N-gram list of Caesar encryption of the document itself would be the most effective for a cryptanalyst to use to decipher a text encrypted with the Caesar cipher as it shows the frequency of each character used in the document. As E is the most commonly used letter of the alphabet, seeing that the highest frequency letter is H with 148 different instances of the letter would indicate that H is the substitute for the letter E. With this known, it can be seen that there is a shift of 3 present in this particular cipher. Once that has been determined, it would be a simple enough task to pair up all the other letters with their associated substitutions, and then translate the document back to its original text. Q2. What do you notice about the histogram results when text is encrypted with the Vigenere cipher in comparison to the results of the Caesar cipher? Why is this the case? The histogram results of the Vigenere cipher show an increase in the frequency of the letters that were u sed in the code word â€Å"applesauce† that encrypted the document. The Caesar cipher does not show this kind of across the board increase in particular letters due to the fact that it does not work off of an encryption key of this nature, but works instead off of an alphabet shift. Q3. There is an error in the following cipher text representation of this quote; what is it? What should the correct cipher text be? SDAHFOWGRABSSRERIVBYBSCIMQTFNIVETGHBSNQCNCSDTDHBSNQCD ECNICIFCTIC The error in the following cypher text occurs in the fourth to last letter of the text. The second to last C that is listed in the above cipher text should be an O instead.

Q4. Of the three ciphers discussed (Caesar, Vigenere, Playfair), what are their relative degrees of secur ity and why? Of the three ciphers discussed, the Caesar is the easiest cipher to break. This particular cipher may be found and used by anyone of any age; I can remember using it back in elementary school in order to pass notes in class. The Vigenere cipher is a bit stronger, requiring a more complex method of analysis in order to determine the proper code needed in order to unlock the â€Å"secret message.† It is the Playfair cipher, however, which shows itself to be the most secure of the three ciphers, as it removes all spacing, or generates its own spacing after every second character, making it impossible to guess the word without the need to â€Å"crack the code† first.

Management Case Study Essay Example for Free

Management Case Study Essay The case study below takes place at the Sir Charles Wilberforce Hospital’s cafeteria, which is experiencing problems with the change management. Due to the new management undertaken by Keith Davis, there was a major issue of inadequate communication channels, as Keith told his employees what to do rather than consult them, especially with the decision-making. The best alternative to rectify this problem is for Keith to adapt to a consultative management style, in order for employees to take ownership in their workplace through expressing their opinions and feel more valued, however still allowing Keith to still make the final decision. Another major issue addressed in the Cafeteria was the amount of unmotivated staff. As employees feel unsatisfied with their work, the best solution to this issue is Goal Setting. Through employees setting strategic goals they will increase their motivation through achievement of these goals which will lead them to set more challenging ones. Lastly, the third major issue recognised was Keith’s poor leadership skills which made it difficult for employees to fulfil expectations and find enjoyment in the workplace. The best alternative solution for this problem is to retrain Keith’s leadership abilities so he is able to adopt all the qualities needed to become a better leader in his managing role. Although this may be an expensive method, the new leadership qualities Keith will learn will make a happier work environment for his employees and build a better employer/employee relationship. 3. Problem identification Poor communication channels Keith focuses on top down communication channels, providing a one way communication which is from him to his employees, rather than two-way which provides his employees to communicate ideas with him. This negatively impacts the hospital as the Keith is unable to discuss problems or ask questions amongst employees to see if there are any problems going on amongst the workers and therefore leading to job dissatisfaction employees. Although Keith tried to soothe Julia when the issue between her and Madison was brought to his attention, he did not follow it up or treat it as an importance. Lack of staff motivation Prior to Keith’s managing, Anne’s original foundations of self-satisfaction and close family ties seemed to motivate the employees at Sir Charles Wilberforce hospital. Keith’s changes were made to become more efficient, employees were left struggling to gain satisfaction and motivation in order for themselves to achieve their hierarchy of needs (Maslow, 1954). In this hierarchy of needs Maslow developed, employees have five needs, physiological, safety, social, esteem, and self-actualisation, once they fulfil one of their needs they can graduate to the next one to fulfil it and so on. Without fulfilling the social needs of forming social ties or self-actualisation of gaining enough experience within the kitchen to become a supervisor, it became unknown to the employees of what they are capable of and decreased their enticements to complete tasks and feel satisfied. Insufficient leadership abilities Keith lacks major leadership qualities, as the organisational layout he uses is to tell employees what to do, depriving them of guidance and support. The Hersey Situations leadership model suggests that leadership focuses on follower’s readiness (Hersey, Blanchard Johnson, 2001). This theory suggests that at Sir Charles Wilberforce, if the employees feel they are unable to complete a task Keith should give those clear and specific instructions. If they are willing and confident Keith needs to provide them display high task orientation, and if employees feel able but are unwilling Keith would need to use a supportive approach. Lack of teamwork The teamwork environment of delegating tasks amongst of employees was not addressed by Keith. He believed that employees needed to finish work on time, plan menus monthly and take on cleaning responsibilities, whereas, the use of team work would have provided a better suited time managed system. Through having each employee assist with cleaning duties, planning menus, helping out another if time was short as well as assisting each other to get all food out and made the kitchen would be less chaotic. This would have assisted with issues if someone was ill, allowing more than one person to prepare greater portions of meals. 4. Statement of Major Problems The three major problems that are brought to the attention at Sir Charles Wilberforce Hospital are: Inadequate communication channels Unmotivated staff Insufficient leadership abilities The poor communication channel Keith utilises is top-down communication from Keith to his employees. As this is a workplace that depends on seeking ideas from others and support from each other, two way communications between Keith and his employees is necessary. This will allow employees to feel part of the decision making and feel they can share their ideas to improve the workplace. Following this Keith must then improve his leadership skills, putting his employees first and assisting them with any help and support they need in order to achieve a positive workplace. This may involve Keith revising the organisation’s culture, or distinguishing the strength and weakness of each employee so he knows how to assist each of them. Once Keith’s leadership abilities are improved, staff motivation must be identified and given, in order for employees to become productive within the kitchen and gain job satisfaction, increasing their abilities and allowing them to feel the want to work. 5. Generation and Evaluation of Alternative Solutions Inadequate communication channels Regular work meetings Set regular meetings within the kitchen, in order to concerns amongst employees to be discussed as we as evaluation on how the business is going and openly discuss ways to improve or maintain it. Advantages Allows for feedback Employees can listen to each person’s idea and encourages discussion openly Evaluate the earnings to the previous week and that time the previous year, allowing each person to suggest ways to improve or maintain their profit margins. Disadvantages Some employees may not attend May be time consuming to discuss all ideas Consultative management style Implement a Consultative management style in order to increase two-way and open communication between Keith and the employees. Advantages Allows employees to feel ownership in decision making Allows employees to share their ideas and opinions Gives confidence to employees Disadvantages Employees may feel held back to express their opinions because they do not feel comfortable Employees may feel offended if their ideas are not taken into consideration Time consuming Unmotivated staff Goal setting Implement setting goals, which involve employees setting goals that motivate them to improve their capabilities. Advantages Gives self-satisfaction Increases productivity and performance levels Disadvantages Time consuming to distinguish appropriate and achievable goals Goals ay appear as unattainable and lead to employees to give up Job design Mr Dev can alter the job design to assist in identifying and correcting any deficiencies that affect performance and motivation. Advantages Job enlargement, can be used to increase motivation by giving employees more and varied tasks so the employee is motivation to try new tasks Job rotation allows an employee to work in different departments or jobs in an organization to gain better insight into operations motivating the employee to increase his/her skills and knowledge about other jobs. Disadvantages Job enrichment may lead the employee transferred too much responsibility in the kitchen and independence in the planning and control aspects of the job which may suppress motivation levels Reward and Recognition Evaluating each employee to identify which people are performing to their maximum, and rewarding them financially or non-financially for their hard work, therefore motivating other employees to improve their work standards. Advantages Employees will increase performance to obtain more rewards Will produce higher standards amongst the employees Self- enrichment Disadvantages Expensive to keep purchasing rewards and reassess each employee to recognise After a while employees may feel that rewards may not motivate them anymore Keith may not want to undertake the idea of rewarding and recognising employees Insufficient leadership abilities Retrain Keith Retraining programs for Keith within the company or externally will allow Keith to develop better leadership qualities and create a happier workplace. Advantages Positively effects employees to feel trust and support from Keith Keith can evaluate themselves as to what skills are expected to lead the employees Disadvantages May take a while for Keith to learn and adapt to these skills May be expensive Dismiss Keith Dismissing Keith will demolish the issue of poor leadership abilities and will allow the business to replace him with a more experienced manager. Advantages Re-appoint a new manager who possess all correct leadership skills Employees are in a happier environment where they can get the support they need More time appropriate and efficient than retraining Disadvantages May be hard to find a replacement Employees may find it hard to adapt to a new manager and may be resistant to give them a chance due to their bad experience with Keith 6. Recommendation Consultative management style A Consultative management style is the recommended alternative for Keith to address to his employees. The type of management style used by Keith at this point is autocratic, which involves him making decisions for the hospital kitchen unilaterally. Although regular meetings are a good alternative by providing mediation and assistant towards employees, the consultative management style involves a permanent change to the organisation. The consultative style would involve Keith discussing ideas of possible changes to be made within the kitchen, as well as employees being able to give their opinions and ideas. By implementing a consultative management style, employees at the cafeteria will be able to perform to their optimum level, concentrating on increasing common sense approach for Keith to meet the needs and wants of the employees, as well as making employees realise their own abilities and capabilities in performing tasks, (McClelland, 1987). Similarly to regular meetings, the consultative approach gives open communication, however unlike meetings the consultative approach is more permanent in the workplace and is used daily, for example in decision making, gaining assistance with a task or getting support with a concern. This will benefit the kitchen, as the employees will respond more positively to any changes to feel more a part of the workplace and a sense of belonging. Keith will benefit from this style, as he will be given a broader range of ideas as well as maintain his authority to make the final decision. Goal Setting Setting goals is the preferred alternative for Keith to use within the kitchen. Despite the fact being rewarded motivates someone to maintain if not improve performance to be rewarded again, goal setting gives motivation. Goal setting enables employees to measure their processes and work performance. This enables employees to gain feedback on their results, unlike rewards and recognition which just motivates employees to try harder to gain another reward rather than possessing the want to gain the self-satisfaction that they have improved. Edward Locke’s theory of goal setting outlines that in setting specific and challenging goals it enables process and outcome improvement (Locke ; Latham, 1990). Similarly, job design suggests a different form of motivating to increase their skills of different tasks, however it also does hold the ability to measure the improvement that setting goals do. If goal setting is adapted by Keith, his employees would be able to achieve towards a higher performance, as well as motivating them to set higher goals with increasingly difficult tasks, once they have been achieved. Through Maslow’s hierarchy of needs, this can assist in setting goals with Locke and Latham’s theory. Maslow theory suggests that ‘although no need is every fully satisfied, a substantially satisfied need no longer motivates an individual to satisfy that need’ (Robbins, Bergmann, Stagg and Coulter, 2012, p559). This suggests that in identifying each need, physiological safety social esteem and self-actualisation, employees at sir Charles Wilberforce can pinpoint what tasks they need to complete in order to graduate to the next level. For example one of the employees may find that they feel they don’t belong, in order to achieve this level they can set a goal to form relations with other employees on a professional basis. Once this goal is achieved they can move on to develop their esteem needs. Retraining Keith Although, retraining Keith may be considered a time consuming process, compared to the alternative of dismissing Keith, it appears to be a more logical approach. Through retraining, Keith is able to gain leadership skills that he may not be aware are essential skills he needs in order to be a manager. This will transform him from telling his employees what to do, to instead assisting and guiding them through changes. Despite the expenses of this method, it may also be difficult for Keith to cooperate as well as understand the concept of these skills however unlike dismissing, he will be able to improve and allow for a happier work. The trait theory suggests that it is impossible to identify and isolate characteristics from leaders from non-leaders. However there are seven traits associated with leadership, these being ‘drive, the desire to lead, honesty and integrity, self-confidence, intelligence, job-relevant knowledge and extraversion’, (Robbins, 2012, p605). Eventually with the retraining, Keith may possess these seven leadership abilities to involve his employees in decision making process and form a trust bond.

Vehicle-to-Infrastructure (V2I) Architecture

Vehicle-to-Infrastructure (V2I) Architecture   Introduction Vehicle-to-Infrastructure (V2I) architecture allows multiple vehicles to communicate with the roads infrastructure. This is then directed towards a central tower that allows multiple vehicles to operate on the same bandwidth. This helps all servers maintain the acceleration and position of all vehicles on streets and roads. This assists in determining everything such as fastest path and/or nearby accidents. Because of this, traffic safety enhancement is the largest factor when it comes to obtaining data from vehicles on and off the road. Also roadside infrastructures are included to provide warnings to vehicles about weather and accidents on its path. For this process to work, gathered speeds and locations within the proximity are reported to the server then to the other vehicles. Because of the large number of vehicles on the road, a central server is needed to relay all the data to each individual vehicle. Dedicated Short Range Communication (DSRC) There are multiple infrastructures that a vehicle can communicate with such as other cars or a control building. Vehicle to Vehicle (V2V) lets multiple vehicles communicate with one another on a given network. DSRC works as a two-way short-range wireless connection. It works similar to WiFi since it allows vehicles to exchange data such as speed, distance, position, and mass of separate vehicles [7]. The primary use of DSRC is for collision prevention. These are achieved by frequent data exchanges among vehicles within a certain range. Each vehicle that utilizes DSRC, casts data from the vehicle to neighboring vehicles multiple times per second within a range between 100-1000 meters in a radius based on the technology [8]. Each vehicle also receives safety messages to warn other vehicles of collisions that the vehicle is driving towards to prepare the driver for what is ahead. Even though DSRC is mainly for collision prevention, it can also be used for assisted navigation such as GPS , electronic payments for tolls, improved fuel efficiency and present traffic updates. According to the U.S. Federal Communications Commission, there is an allocated 75 MHz of licensed spectrum in the 5.9 GHz band for DSRC [9]. This is what the Dedicated is DSRC refers to. This spectrum is divided into several channels. Safety messages are exchanged on Channel 172 and have been designated for safety among vehicles [12]. The term Short Range in DSRC is meant to convey that the communication takes place over a few hundred meters which is shorter than cellular and WiMax services. DSRC communication relies on a manufacturer based standard among devices from different manufacturers for interoperability. The concept of proposed system architecture is shown in Fig. 1. In the United States, vehicles operate on a 5.9 GHz band to operate DSRC. This is then divided into seven 10 MHz channels [11]. Because its running on a 10 MHz channel, all frames within a modulation takes only half as long to transmit than on a 20 MHz channel. This helps reduce collision probability for every f rame transmission per second. Vehicular Ad-Hoc Network (VANET) In VANETs, a vehicle moving along streets in an urban city establishes a network among themselves. Since its development, there have been an increase in commercial and research. In VANETs, mobile nodes are the travelling vehicles since it has high mobility and speed. The main disadvantage of VANET is that the network topology changes rapidly to other forms of vehicle communication. Since VANET equipped vehicles only move on predefined streets, they do not have problems for resource limitation. It is possible for vehicles to obtain a geographic position by using GPS. This can provide good time synchronization through the network. Vehicles within a VANET infrastructure moves within the constraints of traffic flow. This is done while communicating with others. Ad hoc networks use less specialized hardware for infrastructure support. This allows all the stability of the network to be placed on individual nodes. Without dedicated communication hardware, there are other methods placed to attempt to optimize the networks communication to develop a hierarchical based system within the network to help with clustering. To support the VANET environments dynamic nature, clustering must be updated every so often to reflect geographical changes with vehicle movements. The networks clustering must be extremely quick to minimize time lost within the network [13]. VANET has a set of unique characteristics to aid in traditional ad-hoc devices on a mobile network. VANET with high dynamic topology, enough energy and storage space, moving track predictable and diversified automotive network scenarios, has many significant applications in transportation and communication, such as vehicle safety, road traffic efficiency, and information and entertainment [14]. VANET does not have a difficult time when it comes to vehicle shadowing. This happens when a smaller vehicle is shadowed by a much larger vehicle which complicates its communication with infrastructures on the road. In a VANET system, the synchronization between vehicles at a particular speed might be fast due to the networks topology modification [15]. Keeping vehicles anonymous with its data such as the location of vehicles on highways are unidentified to each other. Periodic data exchanges from individual vehicles explain direct infrastructures/vehicles about its position. Yet, the address- position map (APM) will vary frequently because of the relative movements among neighboring vehicles. It is the receivers responsibility to determine the relevance of important messages and decide on appropriate actions [15]. For a VANET system, location based broadcast to other vehicles is the most suitable communication technique when it comes to collision avoidance. Location-based information is an extremely vital measurement when it comes to distance and speed within a VANET system. Geographical routing protocol is important for VANETs since all nodes can determine their own position. All nodes know the position of their direct neighbor. The source node knows the location of the destination. Geographical routing protocol for VANET is more suitable for routing because it doesnt necessarily need route maintenance and does not occupy more bandwidth. Global Positioning System (GPS) The Global Positioning System (GPS) is frequently used in road navigation. Global Position System (GPS) based vehicle tracking is an important application when dealing with mobile Geographic Information system (GIS) in V2V communication. Using GPS for V2V communication has many benefits. One of the main benefits of using GPS is that it is based off of geographic location with a satellite. The main downside of using this technology is that the connection can be lost when driving through a tunnel or a parking garage. There is a plethora of applications to be utilized for GPS vehicle communication. This includes shortest path algorithms based on distance or traffic in a busy city. One of the downsides to GPS is not getting an accurate position for neighboring vehicles to use for data communication with other vehicles. GPS, however, can be used in conjunction with other forms of V2V communication to achieve accurate data that is necessary to relay information to and from one another. One form of this is GPS used in conjunction with DSRC. DSRC gives local data amongst vehicles within a short distance [8], GPS is then used to relay the data that was gathered kilometers away based on the information given from another district that the vehicle is heading towards. In general, GPS devices are used more to navigate rather than to be used for Vehicular communication. It allows needed information such as speed, location, and distance to be communicated from the satellite to the vehicle. Differential Global Positioning Systems (DGPS) can limit the amount of errors from GPS by minimizing or removing them. These include ionospheric effects which affect the propagation of radio waves to and from the vehicle and the tropospheric delay which receives and processes an algorithm to attempt to model or predict the impact of the signal travel time. DGPS is accurate compared to GPS since it gets the information of the vehicle up to a miniscule accuracy. DGPS assists autonomous vehicles with other peripherals to help vehicles accomplish driving tasks such as staying in lane, collision prevention, and checking for speed limits. Even though DGPS is only off by a few centimeters, there are ways to improve its performance. A common solution is integrating with an Inertial Navigation System (INS) [16]. The most common configurations integrate DGPS with high performance 6 degree of freedom INS units. Existing methods for this includes separated INS and GPS units and embedded GPS with INS hardware [17]. GPS/INS integration is typically some form of a Kalman filter (KF), which uses a series of measurements over time. KF based GPS/INS integration can be classified into two categories. GPS-aiding INS where each state in the EKF are INS sensor errors; and the inputs to the EKF are measured between INS and GPS. And INS-aiding GPS where the extended KF states are the INS integration states and the extended KF inputs are GPS measurements [18]. Medium Access Control (MAC) The default MAC layer protocol in V2V Communications uses CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) to avoid collision. A node within the networks infrastructure can sense the communication channel and begin to send out messages once the channel becomes free. However, if two nodes cannot sense each other attempt to send messages to a similar destination concurrently, then both transmissions will fail and retransmissions will be needed. This problem is called the hidden terminal problem. Another type of delay comes from redundant transmission. A vehicle may receive the same message multiple times from different senders. These redundancies will postpone the transmission of other emergency messages. Many solutions have been proposed to reduce the V2V Communications delay. For the interference delay, the key is to let nodes in the interference range transmit at different time, i.e., assigning different transmission slots to these nodes. Decentralized MAC protocols are suitable for vehicular networks due to the dynamically changing set of vehicular nodes [19], and the MAC protocol combining the aspects of centralized and decentralized protocols is proposed in [20]. Each cycle begins with a beacon message from an access point (AP), where the message contains information on the AP and the number of backoff slots. A cycle consists of reassociation slots, data contention slots, and data transmission slots. Based on the slot occurrence information on the previous cycle, the estimation of the number of active nodes and the decision of contention slot size are performed. The MAC protocol is designed for single-rate wireless networks.

Evolution of the Office Worker Role

Evolution of the Office Worker Role Office is the place where people carry out the daily work of their businesses. All the work is done by the support of management policies and co-ordinate the role of various department and sections. Office is the most important part of the organization. Because office provides the base to the organization. It is where all the administrative work of the organization carried out. Employees can meet face to face, so they can enjoy professional and social interactions during their work. To do their work requires suitable environment and sophisticated technologies. Now in modern world due to the rapid growth of technologies significantly effected on office work place. As computers replace the typewriter, servers replaced the bulk files, punching machine/card machine replaces the huge register, email and voice mail eliminates stackable inbox and telephone massage slips and many more. In other word we can say that the technological inventions bring the evolution to the role of office workers. roles of office workers An over view of the past The locally oriented American economy of the early 1800s did not need offices as we know them today. Business was run then much as it had been run for half a millennium. Goods were made, transported, and sold. With the help of a few clerks, merchants ran their small companies as family businesses. (education, 1998) .As the article says in past days the organizations are too small and very difficult to maintain the administrative works. Because of the equipments and technologies used in those days. In those days office environment is not so flexible as today. Because in early days office means a secretary and a clerk. They will carry out their work in a small room. They will do all the works by hand. Eg: writing letters and documents through hand, keeping financial records in huge log books, to keep all business records in huge files. 2.2 factors enforcing to evolution In early 1800s the time offices were born they use very limited equipments and technologies in their work. They use typewriters as main equipment in office to carry out the administrative works like preparing documents and letters. But this type writer brings a lot more easer to do the work in the organizations and government offices. Because it is more suitable way to type a long business document rather than physically writing though the hands. Most of the organization started using it when the concept of scientific management developed in the 1880s. During these days most the clerical works are engaged with typewriters. And they are specialized in typing trough typewriters. Telephone brings an evolution to the way of communication. Since the telephone was first demonstrated in 1876, it has evolved into a vital communications tool, providing the gateway to the world of computer technology and information exchange. (education, office equipment, 1998). Business organization started using telephones to contact with their suppliers. It found more suitable way to send message than sending messages through hand or in mail. Facsimile or fax machine was invented in 1842. It sends a photocopy to another fax machine through telephone cable. It is highly used before email was invented 1843 to 1990. But in this present day also fax machine is use by some organizations. Computer is the most important equipment in the office today. It is hard to imagine conducting business without computers. Each day, millions of people working in offices and homes around the world depend on computer technology to do their jobs efficiently and economically. (office equipment, 1998). In each and every office environment we can see patterns of computers in all departments. But why? It has a valued reason because in present information age all the work office workers in every department is engaged with computer and computer softwares. And mostly all the modern technologies used in offices are under computer control. Eg: account department use special software to carry out their work, punching machine used in offices to mark the r egister of employs is linked with computers in hr department. Computer play biggest role in evolution of office work. When the internet and World Wide Web burst upon American since in the early 1990s, this new form of digital telecommunication forced me to rethink the relationship of information technologies to organization. (Foutain). Internet brings office work more easily done effectively. As it help to find more information about the business environment and competitors. And it helps to communicate throughout the world more easily and fastly at cheaper price. World Wide Web or internet is using in every organization today. Through web pages people can share the information to world. And anyone who wants to advertise the product can advertise through web pages. An email is web based mails through that allows sending files or message to anyone around the world from computer which is connected to the internet. Now in this present day most of the organizations depend on email to communicate with suppliers, customers and between departments. Punching machines is used in offices to maintain the registers of workers in office. Every worker need to place his or her fingerprint on that machine when he or she arrives to the office. So the machine will report to the hr departments computer through sophisticated software so hr people can recognize who are late to the office and who is not coming to office. Then hr manager can talk with employs who are repeating the same mistake. Due to the invention of punching machine it create a lot easier to human resource department. Because it eliminates the huge register which is manage physically by hand. In most offices of the 1990s, personal computers are linked to one other through internaland often externalnetworks. This networking allows employees to gather information from a vast array of outside sources (particularly the World Wide Web) and to share it quickly with their colleagues, outside business partners, and customers. (education, computer networks, 1998). Intranet or computer network in office is very common technology used in big organizations as to communicate between various departments. It is a privacy network which other outside users cant enter. It brings an easy and comfortable method of communication to the office workers. Global Vs local Globally most of the organizations are adept to new technologies and changes in their office environment as well as to the work. There are using the modern technologies to increase the work speed and to increase their productivity. Some international manufacturing companies have stated doing their own researches through research and development department by using modern technologies to invent new ways of production and new technologies. Nowadays the office environment also has been changed from privet cabins to the open floor in order to create a better environment where all the workers can enjoy social and professional interaction. As well as they can share ideas and knowledge. So it helps to new inventions and new ideas. Because of open office environment seems more equality as managers and CEOs are working with their staffs. So it helps managers to supervise and coordinate the works of staffs.
