Networks
Introduction: What is a network?
The computer is a wonderful invention that dramatically increases the amount of work individuals can accomplish independently. However, a majority of our work, whether for school or business, also depends on interaction with others. Some examples are drawn from the fact that lawyers need references from past cases, bankers who need large amounts of financial information and students who need to seek information from many different sources to accomplish their homework or project. Such is reality that nearly every computer user, regardless of how powerful their machine, occasionally needs to draw on resources, which are not available on their desktops. Hence the need for networking. A computer network is defined as two or more computers that are connected to each other and can communicate with each other.
Having a computer without a network would be like a human without a mouth or means of communication. He could create the most wonderful of his own things, but would suffer severely from the lack of information, resources and thus be quite useless.
| The advantages of a computer network is the ability of each computer user to gain resources located on other computers, the chance to share and compare work with many other users, and to use peripheral devices, such as printers or scanners, that might be in short supply. In the modern era, now, it is also used as a very significant form of communication, which includes, email, newsgroups, and even on-line electronic commerce. |  |
For example, a bank customer uses a neighborhood automated teller machine to withdraw or deposit money, and the automated teller machine is networked to a computer at the main bank that will keep track of the customer's transactions. Contrariwise, Electronic Mail, otherwise known fondly as e-mail, travels across networks too, allowing users to communicate with one another. Customers and people from various countries use networks to share resources such as computer files such as websites and other information.
