What is Synchronous serial transmission?
The two parts of this are the serial part, this is where all the information you send is broken down into it’s smallest components – ‘bits’ and these are sent one at a time. A bit is a value which is either 1 or 0 and ( usually ) each letter or character that you see is represented by a unique combination of 8 bits. The next part is the Synchronous part, this means that both ends are involved in the conversation and as data is sent, the receiver will acknowledge what it’s received. This also means if there are transmission problems, that the receiver can ask for parts of the message to be resent. This is more important when using something like a dial up line as there can sometimes be interference on the phone line which will garble the data being sent.
