ANS:A - The floppy COM port is short for communications port. COM ports are also called serialports and on PCs are sometimes called asynchronous communications ports. PCs can normally have up to 4 COM ports. Most PCs have 2 COM ports either built in to the motherboard or on an add-in I/O card. COM ports built in to a motherboard are usually configured with options in CMOS setup but may be configured with jumpers on the motherboard. COM ports on add-in cards are normally configured with jumpers on the card. |
