Bus Topology

A multi-access bus topology used in local-area. In which all node share a singe transmission medium

Data transmission Medium

Transmission media refers to the node of physical connection needed for the transfer of data or signal or bits or bytes between two communicating devices and in the networks between computer when they are exchanging information transmission medium can be through wires or wireless. there are two types of transmission media. Guided / wires media. …

Twisted Pair Cable

Twisted Pair Cable wire consists of two brunches of thin copper wire.  Each brunch enclosed separately in a plastic insulation, then, then twisted around each other to reduce interface by adjacent wires. It is also called Unshielded twisted pair(U T P) cable because other then the plastic insulated around the two individual bunches of copper …

Unguided Media

Unguided Media or wireless communication transport electromagnetic waves with using a physical conductor. The various types of unguided media, there are: Infrared, Radio media, Microwave and Satellite. Infrared It is a new development in data communication. Infrared light to sand data. Infrared light transmits data through the air and propagate in the open space. The …

Satellite

Communication satellite are microwave relay stations placed in outer space. They are launched by rockets or space shuttles, and are positioned 36,000 km's above the equator with  an orbit speed spathe match earth's rotation speed exactly. A satellite is positioned in go synchronous orbit, it is stationary relation to earth, and always stage over same …

Topology

Topology of a network is refers to the way in which the network nodes are linked together. It determines the various data paths available between any pair of nodes in the network. The network uses different types of network topology such are: Bus, Tree, Star, Ring, Hybrid and Mash topology.

IP Address Classes

Internet Protocol addressing supports five different address classes: A, B, C, D and E, only A, B, and C are available for commercial use. Microsoft TCP/Internet Protocol supports class A, B, and C addresses assigned to host. The class of address defines which bits are used for the network ID and which bits are used …
