Abstract:Networkinghardware includes all computers, peripherals, interface cards and otherequipment needed to perform data-processing and communications within thenetwork.Click on a terms below too learn more about those pieces on networkinghardware. It is now time to run our attention from the applications and socialaspects of networking to the technical issues involved in networking designs.Keywords:Routers,Switches,LAN,WAN,MAN 1.INTRODUCTION Network hardware is also known asnetwork equipment or computer networking devices,are physical devices which arerequired for communication andinteraction between devices on a computer network. Specificially they mediatedata in a computer network. Units which are the last receiver or generate dataare called host or data terminal equipment. 2.
TYPESOF NETWORK HARDWARENetwork Hardware can be divided in two types,· Switches· Routers *SWITCHES: From the point of the averagetelephone engineer, the phone system is divided into two parts: outside plantand inside plant. Three differentswitching techniques are used inside the telephone system: circuitswitching , packet switching , message switching. *ROUTERS: Millions of people haveportable computers nowadays and they generally want to read their email andaccess their normal file systems whenever in the world may be. These mobile hosts introduce a new complication: toroute a packet to mobile host, the network first has to find it. They areconnected to the network by copper wires or fiber optics. 3.CHARACTERISTICS OF NETWORK HARDWARE Ø LANØ WANØ MAN *LAN: Theexpansion of LAN is Local area network, generally called LAN’s, are privately owned networks within asingle building or campus of up to a few kilometers in size. They are widely used to connect personal computers and workstations incompany officers and factories to share resources(eg:printers) andexchange information.
*WAN: Theexpansion of WAN is Wide area network .Mobile computers such as notebooks computers and personal digital assistantsare the fastest-growing segment of the computer industry. Many of the owners ofthese computers have desktop machines on LAN’s and WAN’s back at the office andwant to be connected to their home base even when away from home or en route. MAN:The expansion of MAN is MetropolitanArea Network is basically a bigger version of LAN and normally uses similartechnology. It might cover a group of nearby corporate offices or a city andmight be either private or public.
A MAN can support both data and voice andmight be either private or local cable television network. A MAN can one or twocables and does not contain switching element, which shunt packets over one ofseveral potential output lines. 4.CONCLUSION: Sothe conclusion is this network hardware may be connected from point-to-point.Finally, the connection of two or more networks is called an internetwork.
Theworld-wide Internet is a well-known example of internetwork. The NetworkHardware directly connected to switches and routers.
