- 1What is Parallel transmission?This is where a number of wires are used to send data simultaneously, the more wires there are, the more data that can be sent at any time. Parallel transmission is usually used over small distances like buses as over long distances signals will arrive at different times.
- 2What is Serial Transmission?Serial Transmission is where data is sent in series, one bit at a time. It is used to connect most of the peripherals to the computer and is much cheaper than parallel transmission due to less cabling required.
- 3What is bandwidth?It is the amount of data that can be transmitted along a communication channel. However it relates to the frequencies that are available on the carrier wave that carries the data. As the frequency increases, so does the amount of data that can be transferred per second. Bandwidth is measured in (Hz).
- 4What is Bit Rate?Bit rate is the term used to describe the speed at which a particular transmission is taking place. It is measured in bits per second(bps). The higher the range of frequencies, the more data can be transferred therefore the more bits per second.
- 5What is Baud rate?Baud rate is another term used to describe the amount of data that can be transmitted. One Baud represents one electronic signal change per second.
- 6What is Latency?Latency is the time delay that occurs when any computer system is responding to an instruction. It occurs due to the signals taking time to travel down buses and cables and through logic gates. However the delays can be so short they are unnoticeable.
