Auxiliary Hardware For Your Computer

Auxiliary computer hardware is equipment that’s used for input, output and data storage, including an adapter that enables one type of device to communicate with another and a complementary metal-oxide-semiconductor (CMOS), an onboard, battery-powered semiconductor chip inside a computer that stores data, including system hardware settings and system time and date.

In addition to all the items, there’s more computer hardware called auxiliary hardware, of which a computer might have none, or several, of some kinds:

  • Fan (CPU, GPU, Case, etc.)
  • Heat Sink
  • Data Cable
  • Power Cable
  • CMOS Battery: CMOS (short for complementary metal-oxide-semiconductor) is the term usually used to describe the small amount of memory on a computer motherboard that stores the BIOS settings. Some of these BIOS settings include the system time and date as well as hardware settings.
  • Daughter board

Some of the devices listed above are called peripheral devices. A peripheral device is a piece of hardware (whether internal or external) that isn’t actually involved in the computer’s main function. Examples include a monitor, video card, disc drive, and mouse.
