Computer networks allow people and companies to communicate more effectively. They allow for easy sharing of hardware (like scanners and printers) as well as software and data. This allows businesses to cut costs and boost productivity. Computer networking also makes it possible to back up and restore files, which is important in the event of a disaster.
Communication In addition to instant messaging, email systems allow users to share information and collaborate with ease. It is a vital part of the daily operations of modern businesses and enterprises. It lets employees work remotely, and access resources such as applications like file servers, printers, and file devices.
Resource sharing: Networking lets you share the same piece of equipment across multiple computers, which saves time and money. It also speeds up the process of transferring large files and assists you in working on memory-intensive applications.
Increased security: It offers enhanced data security by requiring user ID and passwords for logging in. It also blocks unauthorised users from accessing your devices and lets you decide how much bandwidth each device uses that helps keep your network operating smoothly.
Different kinds of computer networks can be classified according to how devices are connected. For instance the ring topology which looks like a circle connects two devices, bus topology, that has a central line that connects all devices as well as a star-topology that has a central connection point to which all other devices are attached. You must consider the advantages and disadvantages of each before choosing the one that is most suitable for you.
