Description

Full-duplex

Full-duplex communication allows simultaneous two-way data transmission. This means that both the sender and receiver can transmit and receive data at the same time without interfering with each other.

Half-duplex

Half-duplex communication supports two-way data transmission, but only one direction at a time. Devices must take turns transmitting and receiving.

Checksum Options

Option

Description

BCC

BCC is a simple form of checksum that uses a single 8-bit XOR operation on all bytes of the message.

CRC

CRC is a more advanced error-checking method that uses polynomial division to detect more complex errors in transmission.
