In computer networks, networked computing devices exchange data with each other using a data link. The best-known computer network is the Internet. Network computer devices that originate, route and terminate the data are called network nodes. Two such devices can be said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other.

There are various types of computer networks available. We can categorize them according to their size as well as their purpose. The size of a network should be expressed by the geographic area and number of computers, which are a part of their networks. It includes devices housed in a single room to millions of devices spread across the world. What is LAN? What is WAN? What is MAN?
Web Programming Basics! Generally, networks are distinguished based on their geographical span. Subscribe Our Blog. Client-server networks feature centralized server computers that store email, web pages, files, and applications accessed by client computers and other client devices. Learn Networking Basics.

Imagine a flower shop with twenty employees. Now, the store may have one computer and everyone could share it. In this case, everyone needs to be sure that customer records have been updated on all computers every time that a change is required. Likewise, many companies want their personal computers to run their own software and process data independently. But they also want people to share databases, files, and printers, and they want them to share applications software Software that performs a specific task, such as word processing or spreadsheet creation.
A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network may include personal computers , servers , networking hardware , or other specialised or general-purpose hosts. They are identified by hostnames and network addresses.
