Study Notes
Transmission Media
- Guided media for transmission includes twisted pair, coaxial cable, and fiber optic cable.
Line Coding
- The purpose of line coding in digital transmission is to convert the digital signal into a format suitable for transmission over a communication channel.
Error Control Protocols
- The Automatic Repeat Request (ARQ) protocol is based on retransmission of the entire frame when an error is detected.
Modem Function
- The primary function of a modem in data communication is to convert digital signals from a computer into analog signals that can be transmitted over analog communication channels.
Multiplexing Techniques
- Time-Division Multiplexing (TDM) allows multiple signals to be transmitted simultaneously over a single communication channel by allocating a different time slot to each signal.
