Based on the function and network topology

Based on the function: Basically every computer network is functioning as a client and server. But there is a network that has a dedicated computer as a server and the other as a client. There is also a computer that has no special function as a server only. Therefore, based on their function there are two types of computer networks:

• That is client-server.

computer network with a dedicated computer as a server. A service / service can be provided by a computer or more. An example is a domain like www.detik.com lots served by the web server computer. Or it could be a lot of service / services provided by a single computer. Examples are jtk.polban.ac.id server that is a multi-service computer with the mail servers, web servers, file servers, database servers and others.

• Peer-to-peer.

computer network That is where each host can be a server, and also became client simultaneously. For example in the file sharing between computers on the Windows Network Neighborhood Network have 5 computers (we give the name of A, B, C, D and E) that provide access rights to the files they have. At one point A to access the file share of B named data_nilai.xls and also gives access to the file soal_uas.doc C. When accessing a file from B then A serves as a client and as a give file access to C then A serves as a server. Both functions were performed by the same A network like this is called peer to peer.

Based on network topology, computer networks can be divided into:

• a bus topology.
• star topology.
• ring topology.
• mesh topology.
• Topology tree.
• Linear topology.
