The connectivity can be physical by using cables or virtual using wireless network. Local Area Network LAN provides data communication within shorter distance and connects several devices such as computers and printers. This type of network contains computers that are relatively closer and are physically connected with cables and wireless media. Any network that exists within a single building, or even a group of adjacent buildings, is considered as LAN.

It is often used to connect separate LANs together so they can communicate and exchange data. Wide Area Network is connecting two or more LANs together, generally across a wide geographical area. A company may have its corporate headquarters and manufacturing plant located in one city and marketing office in another city. Each site needs resources, data and programs locally, but it also needs to share data with other sites.

To accomplish this, the company can attach devices that connect over public utilities to create a WAN. Usually MANs are not owned by sole organization.

Their communication devices and equipment are maintained by a group or single network provider that sells its networking services to corporate customers.

MANs often take the role of high-speed network that allows sharing of regional resources. Basics of Computer Networks Advertisements.

Basics of Computer Science - Networking

Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cable media or wireless media. The best-known computer network is the Internet. A system of interconnected computers and computerized peripherals such as printers is called computer network. This interconnection among computers facilitates information sharing among them. Computers may connect to each other by either wired or wireless media. Networking engineering is a complicated task, which involves software, firmware, chip level engineering, hardware, and electric pulses.

What is a Computer Network?

A computer networking is a process of connecting two more than two computers with the purpose to share data, provide technical support, and to communicate especially for the business purpose. Internet is the technology that is used to connect different computer systems located in different geographic location. Networking technology has revolutionized the world and created a new arena for the overall development of every nation. Because of having computer networking, a person sitting in the United States of America provides technical support to a person sitting in a remote part of India. With the help of networking, it is very simple to share all formats of digital data from one computer system to another irrespective of their geographic location.
