What is Computer Network

A computer network is a group of devices connected together to share information and resources. These devices, called nodes, can be computers, printers, or other gadgets that can send and receive data. The connections between the nodes are called communication channels.

In a computer network, tasks are shared among several computers instead of one computer doing all the work. Each computer handles a part of the task, making the process faster and more efficient.

Following are advantages and disadvantages

• Security: It restricts user interaction with the entire system, enhancing security. For example, a bank allows users to access their own accounts via an ATM without giving them access to the bank's entire database.
• Faster Problem Solving: Multiple computers working together can solve problems more quickly than a single computer working alone.
• Security Through Redundancy: Running the same program on multiple computers simultaneously provides redundancy. For instance, if one of four computers running the same program encounters a hardware error, the other computers can take over, ensuring continuous operation.
