I/O Port Uses and Types

As desktop computers get smaller and smaller, and more and more PC users are dumping desktop computers for laptop and notebook computers, input/output (I/O) ports are more important than ever before. I/O ports have always been used for connecting input devices such as keyboards and mice and output devices such as printers, but I/O ports can do much more today:

  • Expand your computer's built-in storage without your having to open the cover

  • Create temporary connections between computers for data transfer

  • Add network and Internet capabilities

  • Connect to digital cameras, scanners, DV camcorders, and other types of imaging devices
