Communication and Networking (AQA A Level)

The measure of capacity of the channel down which data is sent?

• Baud Rate

• Bit Rate

• Bandwidth

• Latency

The term used to describe the speed at which data can be transmitted

• Transmission Latency

• Bit Rate

• Baud Rate

• Propagation Latency

(a)   Latency is the amount of time it takes for a logic gate within a circuit to transmit the data

(a)   Latency is the time it takes data to pass around a network depending on how many servers or devices it has to pass through

The signal for which data transmission type will degrade as distance or speed increases?

• Serial

• Parallel

Which data transmission type uses more wires in the cable and is therefore mose expensive to produce?

• Serial

• Parallel

(a)   is the general term used to explain the time delay that occurs when any component within a computer system is responding to an instruction.

Asynchronous transmission relies on the synchronisation of the senders clock?

• True

• False

Start bit, stop bit and parity bit are used in which data transmission type?

• Synchronous

• Asynchronous

(a)   is when data is transmitted one bit at a time down a single wire
