• An asynchronous connection, in which each character
is sent at irregular intervals in time (for example a user
sending characters entered at the keyboard in real time).
So, for example, imagine that a single bit is transmitted
during a long period of silence... the receiver will not be
able to know if this is 00010000, 10000000 or 00000100...
To remedy this problem, each character is preceded by some
information indicating the start of character transmission
(the transmission start information is called a START bit)
and ends by sending end-of-transmission information (called
STOP bit, there may even be several STOP bits).
• In a synchronous connection, the transmitter and
receiver are paced by the same clock. The receiver
continuously receives (even when no bits are transmitted)
the information at the same rate the transmitter send it.
This is why the transmitter and receiver are paced at the
same speed. In addition, supplementary information is
inserted to guarantee that there are no errors during
transmission.
