Computer networks allow individuals and organisations to communicate more efficiently. They enable easy sharing of hardware (like printers and scanners), software and data. This allows enterprises to reduce costs and improve productivity. Computer networking also enables to back up and restore files, which is essential in case of a disaster.
Communication: Using email and instant messaging systems, users can exchange information and collaborate more easily. It is an essential component of the daily operations of modern businesses and organizations. It also enables people to work remotely and access resources, such as applications such as file servers, printing devices and fax machines.
Resource sharing: Networking helps you share the same equipment between multiple computers, which helps you save time and money. It also speeds up the process of transferring large files and helps you work on intensive applications that require memory.
Improved security – It enhances security of data by requiring a user ID and password to log in. It also stops unauthorized users from accessing your devices and lets you decide how much bandwidth each device gets that helps keep the network operating smoothly.
Different types of computer networks can be classified by the manner in which devices are connected. For example a ring topology that resembles a circle connects Bonuses two devices, bus topology, that has one central line connecting all devices or a star topology, where there is an underlying connection point to which all other devices are attached. Each of these has its advantages and disadvantages and you must be sure to consider which matches your needs.
