Metropolis of Area Network (MAN)

Metropolis of Area Network (MAN)
Network MAN represent the development from network LAN which its scope is extended in one metropolis area. Generally MAN used by company or office owning branch or unit work in a town. We can say network MAN connect the computer usher the building in one town.

WIDE AREA NETWORK (WAN)

WAN represent the network computer owning scope very wide, this network constitutoing appearance Internet. Generally WAN used to connect the interregional computer owning distance enough far. Of course this network will be more be complicated and complex when drawn in diagram. In this time between WAN and Internet difficult to be differentiated and almost one coherent infinite.

APPLICATION PROGRAM SPREADSHEET

Application program of number Processor (Spreadsheet) are software used for the process and save data requiring calculation in the form of spread sheet ( sheet), for example: the tables, the list assess, the student list, financial book keeping and others.

Follow the example of the application program of number processor for example :
Lotus 123, Quattro, Quattro Pros, Supercal, Microsoft Excel and Open Office.Org Cals.

Operating System (OS)

Operating system represent the programs used for the control of and arrange entire computer resource. operating system determine the execution work the computer program. follow the example of the Operating System (OS) for example :
MS-DOS, UNIX, LINUX, Microsoft Windows, Solaris And BSD.

LOCAL AREA NETWORK (LAN)

Network Computer owning referred as by tight coverage (LAN), this network a lot of attached at office, factory, school, laboratory, library which only be at one location. Essential requirement in building network local of generally used to share the resource, and transfer the data usher the computer. LAN felt of vital importance when in an space own the computer more than 3 unit. LAN applicable to share printer or other folder peripheral. Also often used for the share of Internet connection. Topology which is at most applied in this time use the STAR with the network center in the form of Switch equitment.

COMPUTER NETWORK

Progressively the increasing of requirement of use computer as a means of assist in finishing some of job human being push the technological progress acceleration computer itself. People progressively dissatisfy by old computer, even will be felt worn out. Data transfer and information is progressively required, this matter push incidence of network computer. So that user shall no longger have to move place to simply to copying data from computer one to computer other. Enough by accessing computer wanted by through network hence all work transfer the data can be conducted during which quickly. Internet as one of successful network computer form formed by human being of totality world cleft.

Network requirement of computer in this time more developed at a speed of transferring data and flexible network. Velocity which can be reached in this time have reached 1Gbps for the network of local, while tired Internet speed newly until grade of Mega- byte per second ( Mbps).

network of Computer sharing of vital importance in the world of effort the example at banking area by system online, network phone the celluler, and a lot still the other. This matter show how important is network computer in this time.

At article hereinafter I will presentation about various network type of according to wide of its coverage area;
