FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Latency refers to the amount of time it takes a packet of data to travel across a network. With satellite service, that data must travel up to the satellite and back (about 45, 000 miles).

Detailed explanation-2: -Message latency is the time elapsed between the time a message is generated at its source node and the time the message is delivered at its destination node.

Detailed explanation-3: -The delay of a packet is calculated by adding the following four components: propagation delay, transmission delay, queuing delay, and processing delay.

Detailed explanation-4: -Processing delay – time it takes a router to process the packet header. Queuing delay – time the packet spends in routing queues. Transmission delay – time it takes to push the packet’s bits onto the link. Propagation delay – time for a signal to propagate through the media.
