2. A process by which data is obtained from a storage device or entered into a storage device in such a way that the process depends on the location of that data and on a reference to data previously accessed. Synonym: sequential access.Source(s): wikipiedia

Your COM1 port is a serial port. It sends bits into the bus in series. It's main disadvantage is that it is much slower than a parallel port. Parallel ports [usually labeled LPT1] send bits in parallel. So, serial [or series] sends a bit one after another, a parallel port sends 8 bits at a time. I haven't seen a computer with a COM1 port being used in a few years. It was mainly for the mouse or maybe a handheld PDA or something, but nowadays the PS2 port or USB port is used for peripheral devices.
