Computer networks enable people and organizations to better communicate. They allow for easy sharing of hardware (like printers and scanners), software and data. This helps businesses reduce costs and increase productivity. Computer networking also makes it possible to backup and restore files, which is important in the event of a disaster.
Communication Instant messaging and email systems enable users to share information and collaborate more easily. It is a vital part of the daily operations of modern businesses and organizations. It also lets users work remotely and access resources such applications, file servers, printing devices, and fax machines.
Resource sharing: Networking allows you to share the same equipment among multiple computers. This saves time and money. It improves the speed at the rate that large files can be transferred and lets you work with programs that require a lot of memory.
Increased security: It offers improved data protection by requiring user IDs and passwords for logging in. It also stops unauthorized users from accessing your devices, and allows you to control how much bandwidth is allotted to each device. This keeps the network operating smoothly.
The different types of computer networks are determined by how the devices are linked to each other, such as the ring topology that appears like a circle and connects each device to two other devices, the bus topology that has a central line, with connections for each device and the star topology which has one central connection point to which all the other devices are connected to. You must look at the pros and cons of each one before making a decision on which one is the best for you.
