Launching of Satellite

A way by which the satellite is kept in the correct orbit in space is known as Satellite Launching. The earth-based stations are responsible for providing proper control to the satellite moving in space. Satellite launching is one of the crucial aspects of satellite communication. Through satellite communication, the exchange of information occurs between multiple …

Satellite Networks

Satellite Networks are defined as the orientation of various elements that establish communication through various nodes from one point of the earth to another point. Any satellite network can provide both types of transmission technologies i.e., point to point as well as broadcasting connections. When we talk about a network through which data is transmitted …

CSMA with Collision Detection

CSMA/CD is an acronym used for Carrier Sense Multiple Access with Collision Detection and is a collision detection protocol. It is basically a refinement/improvisation of CSMA where the user detects the occurrence of data packet collision along with sensing for the availability of carrier in a multiple user network channel. This technique enables us to …

Carrier Sense Multiple Access (CSMA)

CSMA an acronym used for Carrier Sense Multiple Access. It is a type of random-access protocol, where multiple stations transmit their data over a shared channel. However, before transmission, each station senses the channel first and transmits only when finds the channel idle. In CSMA, each station is equally prioritized and thus the transmission occurs …
