What Is Computer Network ?
The Use Of Computer Network:
1. Connectivity and communication
Networks connect computers and the users of those computers, Individuals within a building or work group can be connected into local area networks (LANS), LANS in distant location can be interconnected into larger wide area networks (WANS). Once connected, it is possible for network users to communicate with each other using technologies such as electronic mail. This makes the transmission of business (or non-business) information easier, more efficient and less expensive than it would be without the network.
2. Data Sharing
One of the most important uses of networking is to allow the sharing of data. Before networking was common, an accounting employee who wanted to prepare a report for her manager would have to produce it on his PC. put it on a floppy disk, and then walk it over to the manager, who would transfer the data to her PCs hard disk (This sort of "shoe-based network was sometimes sarcastically called ( sneaker.net"))
True networking allows thousands of employees to share data much more easily and quickly than this More so it makes possible applications that rely on the ability of many people to access and share same data, such as databases group software development, and much more Intranets and extra nets can be used to distribute corporate information between sites and to business partners..
3. Hardware Sharing
Networks facilitate the sharing of hardware devices. For example instead of giving each of 10 employees in a department an expensive color printer (or resorting to the "sneaker net" again) one printer can be placed on the network for everyone to share
4. Internet Access
The internet is itself an enormous network, so whenever you access internet, you are using a network. The significance of the internet and mode society is hard to exaggerate especially for those of us in technical fields.
5. Internet Access Sharing
Small computer networks allow multiple users to share a single internee connection. Special hardware devices allow the bandwidth of the connection t be easily allocated to various individuals as they need it, and permit an organization to purchase one high-speed connection instead of many slow ones..
6. Data Security and Management
In a business environment, a network allows the administrators to much better manage the company's critical data. Instead of having this data spread over dozens or even hundreds of small computers haphazard fashion as their users create it. Data can be centralized on shared servers.
This makes it easy for everyone to find the data, makes it possible for the administrators to ensure that the data is regularly backed up, and also allows for the implementation of security measures of control who can read or change various pieces of critical information..
7. Performance Enhancement and Balancing:
Under some circumstances, a network can be used to (enhance) the overall performance of some applications by distributing the computation tasks to various computers on the network..
8. Entertainment:
Networks facilitate many types of games and entertainment The internet itself offers many sources of entertainment of course In addition, many multi- C players games exist that operate over a local area network Many home networks are set up for this reason, and gaming across wide area networks (including the internet) has also become quite popular of course, if you are running a business and have easily-amused employees, you might insist that this is really disadvantage of networking and not an advantage!
9. Software Cost and Management
Many popular software products are available for networks at a substantial savings in compares to buying individually licensed copied for all of your computers You can also load software on only the file server which saves time compared to installing and tracking files on independent computers Upgrades are also easier because changes only have to be done once on the file server instead of on individual workstations..
10. Flexible Access
Networks allow their users to access files from computers throughout the network. This means that a user can begin work on a project on one computer and finish up on another. Multiple users can also collaborate on the same project through the network.
11. Work-group computing:
Work-group software like Microsoft Back Office enables many users to contribute to a document concurrently. This allows for interactive teamwork.
