Computer. Network

Computer network [is] a system which consist of computer and peripheral of laboring other network together to reach a[n target of [is] same. Intention of computer network [is] to * Dividing resource: the example shar usage of printer, CPU, memory, harddisk * Communications: electronic letter the example, messaging instant, chatting * Access information: the example of web browsing
[So that/ to be] can reach the target of [is] same, each;every part of computer network ask and give service ( service). [Party/ side] asking for service referred [as] [by] client ( client) and giving service referred [as] [by] steward ( server). This architecture [is] referred [as] with system of client-server, and used [by] [at] almost entire/all computer network application
Classification Pursuant to scale * Local Area of Network ( LAN * Metropolitant Area of Network ( MAN * Wide Area of Network ( WAN
Pursuant to function : Basically each;every computer network there [is] functioning as client as well as server. But there [is] network owning special computer [is] dedication as server while other as client. There [is] also which [do] not have special computer function as just server. In consequence pursuant to its function hence there [is] two computer network type * Client-Server
That is computer network with computer which [is] special dedication as server. A service / service can be given by a computer or more. The example [is] a domain like www.detik.com served by many computer of web server. Or can also many service / service given by one computer. The example [is] jtk.polban.ac.id server representing one computer with service multi that is server mail, server web, That is computer network where each;every host can become server as well as becoming client concurrently. The example in file of sharing between computer [in] Network of Windows Network Neighbourhood there [is] 5 computer ( we give the name of A,B,C,D and E) entitling to access to owned file [it]. [At] one moment of A access file of share of so called B [of] data_nilai.xls as well as giving to access file of soal_uas.doc to C. Moment of A access file of B hence functioning A as moment and client of A give to access file to C hence functioning A as server. Both [of] that function [is] [done/conducted] by A concurrently hence network like this named [by] peer to peer
Pursuant to network topology : Pursuant to [ network topology], computer network can be differentiated of * Bus topology * Topology Star * Topology Ring * Topology of Mesh ( Random * Topology Tree ( Hierarchical * Linear Topology.
