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?
Chapter 1: What is a Network?
A computer network is a group of computers linked to each other that enables the computer to communicate with another computer and share their resources, data, and applications. A computer network can be categorized by their size. A computer network is mainly of four types :. It is a low range network. Extranet: An extranet is a communication network based on the internet protocol such as Transmission Control protocol and internet protocol.
Definition and types of computer networking
To know the definition of the Computer Network. Let us discuss the simple definition of the Computer Network. A computer network is a set of communication elements that are connected by communication links. The definition tells the set of elements are connected by the wireless or wired links. The Network is to support the way how we communicate with the people. In previous days, we use the traditional landline communication channel. In this type of landline communications, the data is sent only in the form of voice communication.
What is Computer Network with Examples
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. Computer networks support an enormous number of applications and services such as access to the World Wide Web , digital video , digital audio , shared use of application and storage servers , printers , and fax machines , and use of email and instant messaging applications as well as many others.
Computer network , two or more computers that are connected with one another for the purpose of communicating data electronically. Besides physically connecting computer and communication devices, a network system serves the important function of establishing a cohesive architecture that allows a variety of equipment types to transfer information in a near-seamless fashion. LANs connect computers and peripheral devices in a limited physical area, such as a business office, laboratory, or college campus, by means of links wires, Ethernet cables, fibre optics , Wi-Fi that transmit data rapidly. A typical LAN consists of two or more personal computers , printers, and high-capacity disk-storage devices called file servers, which enable each computer on the network to access a common set of files. LAN operating system software , which interprets input and instructs networked devices, allows users to communicate with each other; share the printers and storage equipment; and simultaneously access centrally located processors, data, or programs instruction sets.
