Question

Explain how Cyclic Redundancy Check (CRC) can be used in communication network environment

Expert Solution

Cyclic redundancy check.

Successful communication between devices is key to proper functioning of embedded systems.
Embedded systems rely on and work with a protocol or set of rules that govern the transmission, synchronization, and error checking of data sent and received between devices.
Protocols are essential components in the operation of embedded systems, so it's important that they work well.
Communication errors occur, so many protocols such as USB, CAN, and A2B have built-in error checking mechanisms such as Cyclic Redundancy Checks and CRCs. CRC is used to mark corrupted data and prevent it from being sent over the bus.
Today's protocols often support higher bandwidths and speeds, so CRCs are essential to keep data clean and reliable within embedded systems. Dfferent ways CRCs are used in different protocols.
