Communication Basics (AQA A-Level Computer Science): Flashcards

Sends data one bit at a time down a single wire

Sends multiple bits simultaneously using multiple wires

Range of frequencies on carrier wave, measured in hertz (Hz)

Actual speed of data transmission, measured in bits per second

Number of electronic state changes per second

Time delays during data transmission between devices

Propagation, transmission, and processing latency

Devices synchronise signals for continuous data flow

Start bits and stop bits to coordinate data transfer

Set of rules defining how transmission should take place
