B. MAIN LESSON

Content Notes THE NEED FOR NETWORKING Let us be more precise in justifying the need for networking among computers and computer- related devices such as printers. Why do we need to be connected to a network? Why are small computers often connected to larger machines? Why is it critical for most businesses to be connected to the Internet?

Sharing of Technology Resources Networking permits the sharing of critical (and often expensive) technology resources among the various users (machines) on the network. For example, by putting all of the PCs in an office on a LAN, the users can share a variety of resources, such as a high-speed color printer that is a part of the network. The users can also share software that is electronically stored on a file server (another computer designated for that particular purpose). All these devices are connected by wiring (or a wireless network) and are able to communicate with one another under control of a LAN software package called a server (or network) operating system. When a particular user wants to print a color brochure or a color transparency, it is sent electronically from the user’s machine to the network printer. Sharing resources is also important for larger computers. It is quite common for mainframes or midrange computers to share magnetic disk devices and very high-speed printers. Further, wide area networks (WANs) permit the sharing of very expensive resources such as supercomputers. Sharing of Data Even more important than the sharing of technology resources is the sharing of data. Either a LAN or a WAN permits users on the network to get data (if they are authorized to do so) from other points, called nodes, on the network. It is very important, for example, for managers to be able to

retrieve overall corporate sales forecasts from corporate databases to use in developing spreadsheets to project future activity in their departments. In order to satisfy customers, automobile dealers need to be able to locate particular vehicle models and colors with specific equipment installed. Managers at various points in a supply chain need to have accurate, up-to-date data on inventory levels and locations. Accountants at corporate headquarters need to be able to retrieve summary data on sales and expenses from each of the company’s divisional computer centers. The chief executive officer, using an executive information system, needs to be able to access up-to-the-minute data on business trends from the corporate network. The ultimate sharing of data is now occurring via the World Wide Web on the Internet. By conservative estimates, there are now at least 1 billion users of the Web at sites around the world, and this number continues to grow rapidly. Each of these users has easy (and often free) access to an incredible array of information on any topic. The user begins by using a search engine such as Google or a favorite reference site and then follows hypertext-based links to seek out the desired data. In short, the Web has created a new and exciting way of sharing data.

Distributed Data Processing and Client/Server Systems With distributed data processing, the processing power is distributed to multiple computers at multiple sites, which are then tied together via telecommunications lines. Client/server systems are a variant of distributed systems in which the processing power is distributed between a central server system, such as a midrange computer or a mainframe, and a number of client computers, which are usually desktop microcomputers. Distributed and client/server systems tend to reduce computing costs because of their reliance on more cost-effective microcomputers and workstations. There are many examples of distributed systems. One is the use of laptop computers by a company’s sales force, where orders and sales data are transmitted over the Internet (using a virtual private network, to be discussed later in this chapter) to the corporate computer center. A second example is the use of a client/server application for general ledger accounting, with desktop microcomputers as the clients and a high-powered workstation as the server. In most cases, such a package is implemented over a LAN in a single building or a cluster of buildings (a campus). A third example, also a client/server system, involves the creation of a commercial real estate database on a server located at the real estate firm’s main office. The client machines are microcomputers located in the firm’s branch offices or customer offices, with the clients and server linked via the Internet. In any case, it is the existence of a telecommunications network that makes distributed data processing a feasible and attractive arrangement.

Enhanced Communications Networks enhance the communications process within an organization (and between organizations) in many important ways. The telephone network has long been a primary means of communication within and between organizations. Electronic mail over the corporate computer network has become a mainstay of communication in most major organizations in the past two decades, and the development of the Internet has extended the reach of these electronic mail systems around the world. Electronic bulletin boards (including internal, regional, and national bulletin boards), blogs, and mass electronic mailing lists for people with common interests permit multiparty asynchronous communication on an incredible array of topics. Instant messaging permits synchronous text communication over the Internet. And video communication, especially videoconferencing, provides a richer medium to permit more effective communication.

Editorial involves checking for errors and putting the communication into a standardized format, and conversion includes any necessary changes in the coding system or the transmission speed when moving from one device on the network to another. In networks where alternative paths are possible between the source and the destination of a communication (particularly WANs and the Internet), routing—choosing the most efficient path—is an important task. Closely related to the processing function is network control, which includes keeping track of the status of various elements of the system (e., which elements are busy or out of service) and, for some types of networks, checking each workstation periodically to see if it has a communication to send. A not-so- obvious but critical function is the provision of an interface between the network and the user; hopefully this interface will make it easy and efficient for a manager or any other network user to send a communication.

C. LESSON WRAP-UP

FAQs:

  1. Why do we need to be connected to a network? Answer: Computer networks help users on the network to share the resources and in communication. File sharing: Networking of computers helps the network users to share data files. Hardware sharing: Users can share devices such as printers, scanners, CD-ROM drives, hard drives etc.

  2. What is the first message sent over the internet? Answer: The first message sent on the internet on October 29, 1969, was 'LO'—because the network crashed after the first two letters. The programmers attempted to type in and transmit the word "login" from UCLA to SRI, but the system crashed right after they typed in the "o." The programmers were able to transmit the entire "login" message about an hour later.

Thinking about Learning Mark the place in the work tracker which is simply a visual to help you track how much work you haveaccomplished and how much work there is left to do. This tracker will be part of your activity sheet.
