Computer networks enable people and organizations to better communicate. They enable easy sharing of hardware, software (such as printers and scanners) and information. This allows companies to cut costs and increase productivity. Computer networking also enables to backup and restore files, which is vital in case of a disaster.
Communication: Using instant messaging and email systems users can exchange information and collaborate more easily. It’s an integral element of the day-to-day operations of modern enterprises and businesses. It also lets users work remotely and access resources such as applications, file servers, printing devices, and fax machines.
Resource sharing: Networking enables you to share the same equipment among multiple computers. This saves both time and money. It also increases the speed of moving large files and helps you work on memory-intensive applications.
Increased security: It offers improved data protection by requiring user IDs and passwords to login. It also blocks unauthorized users from using your devices, and allows you to decide how much bandwidth is allotted to each device. This keeps the network operating smoothly.
The different types of computer networks are based on the way the devices are linked to one another like the ring topology that looks like an oval and connects every 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 other devices are connected to. Each has its advantages and disadvantages, so you should be aware of which suits your needs.
