Answer : Network Requirement When multiple computers located at different distances can exchange and process information through interconnection, the whole system is also called computer network or just network. The main advantage we get when two computers are brought through a network is that two computers can share each other's resources. Resource refers to information and hardware devices. Personal computers are called personal usable computers. But even when many PCs are used in an organization, only one user can use a computer. But if a suitable network can be built between the computers, then the information of one computer can be used by another computer. As a result, there are many benefits to working. Many people can use a single hardware device together without using a single network. Suppose an office has five computers and one printer. Printers do not always work. As a result, five users can share and use the printer through the network. Nowadays we use the internet. The Internet is also a kind of network. Wire , optical fiber , microwave, etc. are used as interconnection means in computer networks . Through this medium, information is transmitted from one computer to another. Each computer used in the computer network can act as a separate computer.
