Computer networks enable individuals and organisations to communicate more effectively. They enable easy sharing of hardware (like scanners and printers), software and data. This helps companies cut costs and improve productivity. Computer networking also enables to back up and restore files, which is important in the event of a disaster.
Communication The use of email and instant messaging systems enable users to share information and collaborate better. It is an integral part of the day-to-day functioning of modern enterprises and businesses. It also enables people to work remotely and access resources like applications such as file servers, printing devices, and fax machines.
Sharing resources: Networking lets you share the same equipment across multiple computers, which helps you save 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 ID and passwords for logging in. It also prevents unauthorized people from using your devices and lets you limit the amount of bandwidth each device gets to keep the network running smoothly.
Different kinds of computer networks can be classified according to the way in which devices are connected. For instance the ring topology which resembles a circular shape, connects two devices, bus topology that has one central line that connects all devices and a star topology that has an underlying connection point to which all other devices are connected. Each has its pros and cons and you must be aware of which matches your needs.
