Networking is a composite part of computing that constitutes a major proportion of the IT world. Without networks, almost all communication in the world would end up. Networking is the technology behind the working of telephones, televisions, the INTERNET, etc. The Computer Networks can be divided into categories depending upon their geographical scope, however, the three main categories of Computer Networks can be defined. The Three Types of Computer Networks are briefed below: Local area network (LAN):A local area network spreads across a relatively small space. It offers services to a very small proportion of users. On the basis of the number of people using the Local Area Network, a peer-to-peer or client-server method of networking can be opted for. A peer-to-peer network is one in which each client shares their resources with other workstations existing in the network. A client-server network offers the connection of client with server and each other. Client-server networks utilize servers in different capacities.
All Computers in a Network are connected using the Ethernet Cable. The connection between the computers can be established by either a direct connection or with a network hub that allows multiple connections. Historically, LANs have always offered much higher speeds than WANs. It's not necessary that the WAN technology will also show similar results when used in Metro Ethernet or implemented over optical transmission systems.
Wide area network (WAN) : A wide area network is a network in which an extensive range of computer resources are distributed over a large domestic area or internationally. The largest and best example of a WAN is the Internet, which in turn is a network made up of numerous smaller networks. The Internet is perhaps the largest network in the world. Also, PSTN (Public Switched Telephone Network) is an enormously large network that uses Internet technologies.A Wide Area Network involves communication using a variety of technologies. The technologies used may be Point-to-Point WANs such as Point-to-Point Protocol (PPP) and High-Level Data Link Control (HDLC), Frame Relay, ATM (Asynchronous Transfer Mode) and Sonet (Synchronous Optical Network). The basic difference between the WAN technologies is defined on the basis of the network's switching capabilities and the rate of speed at which the sending and receiving bits of information (data) are transmitted.
Wireless networks (WLAN, WWAN): A wireless network resembles a lot with LAN or a WAN but the major difference in Wireless networks is the absence of any wires between hosts and servers. Thus, so called The data is transported over sets of radio transceivers. Wireless networks are best suitable in situations when it is too expensive or inconvenient to run the necessary cables. The media access protocols for LANs are derived from the IEEE.
For larger areas, communications satellites of various types, cellular radio, or wireless local loop (IEEE 802.16) are taken into use . These devices have their own distinct advantages and disadvantages. On the basis of the type of mobility required, the relevant standards may come from the IETF or the ITU. Thus, we see that Networking is truly the Host in IT Communications! For more information on Wireless Networking Solutions, LANs, WANs, see
