Each computer or device in a network is called a node. The geometrical arrangement of computer resources, remote device and communication facilities is know as network topology. It determined data paths that may be used between any two pairs of stations of the network.
Types of network topology:
Ring network:
It is form of circle as far as the nodes are connected. Computer are linked path or in ring. It doesn’t require central host computer. Thus each nodes of ring network must have simple communication capability.
Completely connected network:
It is combined using physical link (cables). Each computer of such computer has a direct dedicated link called point-to-point link with all other computer of network.
Transmission Media:
Data required some media to travel and that cables provide this platform with help of microwaves also but it is too much expensive. Commonly the cables are used they are follows:
Coaxial cable:
It consists of many small wires/cables of copper or aluminum in a protective cover. It is able to transmit data at higher rates. It is popular cable for connecting computer terminals.
Fiber cable:
It is thin and flexible like human beings. It is useful to transfer large volume of data. It is more expensive and difficult to work and harder to install.
