Large packets of data are broken down to small packets before it is sent over a network. This article explains how routing, compression and flow control enables...

Synchronous communication is a form of data transmission between devices that is synchronised.

Asynchronous communication refers to digital communication between devices. There is no timing requirement for transmission.

During data transmission, errors occur as a result of noise and other corruptions during data transmission. Parity bits are used to check for errors during data transmission.

CRC (cyclic redundancy check) is a better error checking method when compared to the parity bits. CRC uses some complex mathematical calculations to check for errors...
