1
Define serial transmission.
Data is transmitted one bit at a time down a single wire
2
Define parallel transmission
Data is transmitted several bits at a time, using multiple wires
3
Give two advantages of serial over parallel transmission
1) Serial requires less cabling, so it is cheaper
2) Bits always arrive in the correct order
4
What is synchronous data transmission
Data transmission between two devices where the clock of the sending device and the receiving device are in time with each other (the devices share a common clock)
5
What is asynchronous data transmission
Data transmission between two devices that do not share a common clock signal. A start bit indicates the start of the transmission of data; a stop bit indicates the end of the transmission.
6
Under what circumstances would you use synchronous data transmission
When there is a constant flow of data between two devices, for example when streaming online videos.
