The name serial communication comes from
the fact that each bit of information is transferred in series from one location to another.
Serial communications are of two types
Synchronous and Asynchronous
Synchronous communications
sending and receiving ends of the communication are synchronized using a clock that precisely times the period between bits. By checking the clock the receiving end can determine if a bit is missing or introduced in the stream.
Asynchronous communications
the bit stream is marked to help keep track of each bit. The start bit indicates the start of the data stream and the timing of each bit helps in finding the position of each bit. Here, timing is not important but the speed of the ports should be the same.
In a serial port
communication takes place through a single line\circuit. The data is transferred one bit at a time from sender to receiver. The serial port takes 8, 16, or 32 parallel bits from the computer bus and converts it to a bit serial stream.
Parallel ports
the easiest to use and work with as they are fast and mostly problem free.Sends its information in parallel signal wires.

send their data at 115,200 bits per second and new enhanced parallel ports will go up to 100 times faster.

IEEE 1394A is capable of transferring data at speeds of up to
400 megabits per second
IEEE 1394B is capable of transferring data at speeds of
800 megabits per second.
IEEE 1394
fastest external i/o bus available, can support up to 63 devices, and is optimal for bandwidth-hungry devices (such as digital video cameras and external storage devices.)
