Network Type


The network type associated with the network operating system. There are two types  network, ie client-server and peer to peer type network.

a) Client-Server Networks 
Servers are computers that provide facilities for komputerkomputer  others in the network and the client is a computer-computer  who receive or use the facilities provided by the server.  Server in client-server type of network called a Dedicated Server  because the pure act as servers that provide facilities to  workstations and servers can not serve as  workstation.  

Excellence
· Higher access speeds due to the provision of network facilities and  management is carried out exclusively by a single computer (server)  that is not burdened with other tasks such as workstations.
· Security systems and network administration is better, because  there is a computer that served as the administrator network, which manages the administration and network security systems.
· Data backup system is better, because on a client-server network backups performed centrally at the server, which will backup all
data used in the network.
Weakness
· Cost is relatively more expensive operation.
· Required the presence of one particular computer which enabled more to be assigned as a server.
· Tissue viability depends on the server. When the server  impaired the overall network will
disturbed.16

b) Peer To Peer Network

When viewed from a server role in both types of networks, the  server in the network of peer to peer type is termed non-dedicated server,  because the server does not act as a pure server but at the same time  can serve as workstation.

Excellence
· Inter computers in the network are able to share facilities  who has such as: hard drive, drive, fax / modems, printers.
· Cost relatively cheap operation compared with the type  client-server network, either because they do not require any  server that has a special ability to organize and provide networking facilities.
· Viability of the network is not dependent on a single server.  So if one computer / peer dead or damaged tissue as a whole will not experience interference.

Weakness
· Troubleshooting network is relatively more difficult, because the tissue type  peer to peer every computer it is possible to engage in  existing communications. In client-server network, communication is between the server and workstation.
· The performance is lower compared to client-server network,  because every computer / homework in addition must manage the use of  network facilities also have to manage the job or the application itself.
· Network security system is determined by each user  to regulate the safety of each facility owned.
· Since data networks spread in each computer in  network, the backups should be performed by each computer them.
