What is Bit Stuffing? Bit stuffing is the process of adding one extra 0 whenever five consecutive is follow a 0 in the data, so that the receiver does not mistake the pattern 0
Along any transmission path from a given source to a given destination, a group of virtual circuits can be grouped together into what is known as path.
Explain Presentation layer in OSI model
MPI contains hundreds of functions, a small subset of which is enough for most practical purposes. We shall talk about some of them in this unit. Functions for MPI Environment:
Distributed Shared Memory (DSM) systems copy a shared memory abstraction on loosely coupled architectures in order to allow shared memory programming despite missing hardware suppo
Q. Explain about Multiplicative Decrease ? Multiplicative Decrease (MD) if a time-out take places the threshold is set to one maximum segment size (TCP Tahoe, TCP Reno).
Design the user interface for mode switching and data entry any way that you like. For example, to switch an application from transmit mode to receive mode, you can give it special
