Computer networks allow people and organizations to better communicate. They allow for easy sharing of software, hardware (such as printers and scanners), and information. This helps businesses reduce costs and increase productivity. Computer networking also makes it possible to backup and restore files, which is important in case of a disaster.

Communication: With email and instant messaging systems, users can exchange information and collaborate more easily. It is an essential part of the daily functioning of modern enterprises and businesses. It also enables people to work remotely and access resources like applications like file servers, printers, devices, and fax machines.

Resource sharing: Networking enables you to share the same equipment between multiple computers. This helps save time and money. It also speeds up the process of transfer of large files and helps you work with memory-intensive programs.

Improved security – It improves data protection by requiring a user ID and password to sign in. It also blocks unauthorized users from accessing your devices. It also lets you decide how much bandwidth each device uses, which helps keep the network running smoothly.

The different kinds of computer networks are based on how the devices are linked to each other for example, the ring topology that appears like an arc and connects each device to two other devices or the bus topology, which has a central line that includes connections for each device and the star topology with one central connection point to which all the other devices are connected to. It is important to look at the advantages and disadvantages of each one before choosing the one that is most suitable for you.
