Async, Sync And Line Coding

Question 1

what is meant by maintaining synchronicity?

Answer 1

Data is sent one bit at a time and the timing of these bits must be the same at both transmit and receive terminals to prevent errors occurring

Question 2

Define Synchronous systems?

Answer 2

These systems require extra elements added to a transmitted data stream to inform the receive terminal where a block of data begins and ends. To prevent errors occurring clocking devices at both transmit and receive terminals must be synchronised

Question 3

Define Asynchronous Systems?

Answer 3

These systems require extra elements added to a transmitted data stream to inform the receive terminal where a WORD begins and ends. These systems do not require any linked timing devise to maintain synchronicity
