Computer networks allow people and organisations to communicate better. They allow for easy sharing of hardware (like printers and scanners), software and data. This allows businesses to reduce costs and improve productivity. Computer networking lets you backup and restore files in the event of a catastrophe.
Communication: With email and instant messaging systems users can exchange information and collaborate more easily. It is an essential part of the day-today operation of modern businesses and enterprises. It also enables people to work remotely and access resources like applications like file servers, printers, devices and fax machines.
Resource sharing: Networking lets you share the same equipment among multiple computers, which saves time and money. It improves the speed with which large files can be transferred and allows you to work with memory-intensive software.
Security enhancements – It increases security of data by requiring user ID and password to log in. It also stops unauthorized users from accessing your devices, and allows you control how much bandwidth is allotted to each device. This keeps the network operating smoothly.
The various types of computer networks are based upon how the devices are linked to one another, such as the ring topology that looks like an arc and connects each device to two other devices or the bus topology, which has a central line with connections for each device, or the star topology with one central point of connection that all the other devices are connected to. Each of these has its advantages and disadvantages, so you should take your time deciding which one best fits your needs.
