Modes of data transmission
and Multiplexing
, Serial Communication
• In serial communication, data transmission occurs bit by
bit on a single communication line or channel. This process
means that data bits are sent one after the other in a
sequence or series (hence the term 'serial'), with the
receiving device collecting and reassembling these bits
into a complete message.
, • In simple terms, serial data transmission is like a single-lane road where cars
can only travel one after the other, not side by side. Here is a simple
breakdown of how serial data is transmitted:
1.Start of communication: The device sending the data, called the transmitter,
sends a start bit to the device receiving the data, known as the receiver. The
start bit is like a heads-up, signaling, "Hey, I'm about to send some data."
2.Data transmission: Next, the transmitter sends the data bit by bit in a
specific order. It's like sending a long message, one letter at a time.
3.End of communication: When all the data bits have been sent, the
transmitter sends a stop bit, saying, "That's it, I've sent everything I had to
send."
4.Error checking (optional): The receiver then checks if it has received the
data correctly. This is done through a process known as parity checking. If the
data isn't correct, the receiver can ask the transmitter to resend the data.
