It can be an abbreviation for several things. In part, I am borrowing
from PCWebopedia here:
(1) In DOS systems, the name of a serial communications port. DOS
supports four serial ports: COM1, COM2, COM3, and COM4. However, most
software uses system interrupts to access the serial ports, and there
are only two IRQ lines reserved. This means that the four COM ports
share the same two IRQ lines. Typically, COM1 and COM3 use IRQ4, while
COM2 and COM4 use IRQ3. So in general, if you have two devices, one of
which is attached to COM1 and the other to COM3, you cannot use them
simultaneously.
(2) Abbreviation of Component Object Model
(3) .com is a generic TLD (Top Level Domain), which indicates a
"commercial" or "company" domain.
