Computer network is aninterconnection of computer for sharing of information according to somespecified rules or protocols. This data is transmitted through OSI (open systeminterconnection) model. In this process in one device is able to send/receivedata to/from at least one process residing in a remote device, then the twodevices are said to be in a network. A network is a group of devices connectedto each other. Networks may be classified into a wide variety ofcharacteristics, such as the medium used to transport the data, communicationsprotocol used, scale, topology, benefit, and organizational scope. In thisarticle I will make you aware about the some of the common terms used in thefield of networking:· Computer Network: Computer network is aninterconnection of computer to transmit information between computers through acommunication channel. This can also be classified on the basis of flow ofinformation like as half duplex and full duplex.· Network Topology: Network topology is ageographical representation of network. In general, a computer network istechnically classified based on the topology of the total network whichincludes the structure of the networks too. They are divided into Bus networks,Ring network, Star network, Mesh network, Star-bus network, Tree network,Hybrid network.· Routers: Routers is a device which isdesigned to forwards the data packets that it receives, to the next availableor neighboring between the networks.· Switches: Switches are the virtualcontrollers of routers and bridges. Switches control the flow these areoperated from each of the individual layers of the OSI layer. Certain caseswhere the devices operate on multiple layers are called multilayer switch.· Bridges: Technically, a bridge acts aconnector between the data link layer and the network layer. The three types ofbridges are Local Bridges, Remote Bridges and Wireless bridges. Bridges come inthree basic types:1. Local bridges: Directly connectLANs2. Remote bridges: Can be used tocreate a wide area network (WAN) link between LANs. Remote bridges, where theconnecting link is slower than the end networks, largely have been replacedwith routers.3. Wireless bridges: Can be used tojoin LANs or connect remote stations to LANs.· Network Cards: Network cards are the mostimportant hardware component of a network. The most important functionality ofthe layer is to enable communication between the computers in a network.· Firewalls: A firewall is an importantaspect of a network with respect to security. It typically rejects accessrequests from unsafe sources while allowing actions from recognized ones. Thevital role firewalls play in network security grows in parallel with theconstant increase in 'cyber' attacks for the purpose of stealing/corruptingdata, planting viruses, etc.· Repeaters: A repeater is an electronicdevice that receives a signal, cleans it of unnecessary noise, regenerates it,and retransmits it at a higher power level, or to the other side of an obstruction,so that the signal can cover longer distances without degradation. In mosttwisted pair Ethernet configurations, repeaters are required for cable thatruns longer than 100 meters.· Hub: A repeater with multiple portsis known as a hub. Repeaters work on the Physical Layer of the OSI model.Repeaters require a small amount of time to regenerate the signal. This cancause a propagation delay which can affect network communication when there areseveral repeaters in a row. Many network architectures limit the number ofrepeaters that can be used in a row.For anyproblem related to computer network use onlinetechnical support provided by some well renowned companies like impcsupport.
