The unguided transmission media is one which does not use the physical medium to transmit information from one computer to another. Unlike the guided transmission media, the unguided transmission media utilize air as a transmission media instead of wire or cable so it is also termed as ‘wireless transmission media’. The wired or guided transmission media are good at their … [Read more...] about Unguided Transmission Media

Communication satellites are human-made satellites that work in such a way that the satellite receives a signal from one point on earth, amplifies the signal and send it back to another point earth using transponders. Thus, it creates the communication network between the source that transmitted the signal and receiver. Communication satellite or the artificial satellite can … [Read more...] about Communication Satellites

Guided transmission media is the physical medium that is used to transfer information bits from one computer to the other. The physical medium directs the path that information bits have to follow to reach the desired receiver. The other transmission medium is the unguided transmission media which does not incorporate any physical medium for the transmission of the … [Read more...] about Guided Transmission Media

Distance Vector Routing protocol is a 'dynamic routing' protocol. With this protocol, every router in the network creates a routing table which helps them in determining the shortest path through the network. All the routers in the network are aware of every other router in the network and they keep on updating their routing table periodically. This protocol uses the principle … [Read more...] about Distance Vector Routing Protocol

Mobile IP is a communication protocol that enables a host to move from one network to another while still being connected to its home network. Mobile IP allows a mobile host to communicate with the remote host being in a foreign network. It is the improvised version of Internetworking Protocol (IP) that boosts mobile communication. In this section, we will discuss mobile IP, … [Read more...] about Mobile IP
