•
Baud:
The number of signal changes made to the transmission medium per second. Each
symbol can represent or convey several bits of data.
•
Data bit:
The number of bits that are conveyed or processed per unit of time in data
communication. The data bit is quantified the actual data using bits per second except Parity,
Start bit, Stop bit, or control signals.
•
Stop bit:
In Asynchronous data transmission, a stop signal (last 2 bits) is sent after each
codeword to bring the receiving mechanism to rest in preparation for the reception of the next
symbol.
•
Parity:
A bit added to ensure that the number of bits with the value one in a set of bits.
•
Flow Control
: The process of managing the data transmission rate, so that the receiving
node is not to miss or lock up by overwhelmed data
