Define serial transmission.
Data is transmitted one bit at a time down a single wire
Define parallel transmission
Data is transmitted several bits at a time, using multiple wires
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
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)
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.
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.
Under what circumstances would you use asynchronous data transmission
