NETWORK TOPOLOGY

NETWORK

A network consists of multiple computers connected using some type of interface, eachhaving one or more interface devices such as a Network Interface Card (NIC) and/or a serial device for PPP networking. Each computer is supported by network software that provides the server or client fuctionality. The hardware used to trasmit data across the network is called the media. It may include copper cable, fiber optic, or wireless trasmision.

TOPOLOGY

When we talk of topologies, we are talking of the manner in which network devices are organized. Topology is a term that refers the shape of the network and the layout of cabling from a bird's eye view, much as a floor plan identifies the layout of offices and hallways in a building. Topology refers to the way in which the network of computer is connected. Each topology is suited to specific tasks and has its own advantages and disadvantages.

The choice of topology is dependent upon

		type and number of equipment being used

		planned applications and rate of data trasfers

		required response times

		cost

There are FOUR major competing topologies

You'll find a lot more in Bus Topology

You'll find a lot more in Ring Topology

You'll find a lot more in Star Topology

You'll find a lot more in FDDI Topology
