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.
