  • Physical maintenance strategies for use of a computer system  11 ATAR, 12 GEN

    • use of an uninterruptible power supply (UPS)
    • environmental temperature control


  • BE CLEAR ON THIS - The current AIT syllabus dictates that UPS and environmental temperature control are the items to be described for this topic.
  • Both of these are more suited to computer sytems in a server room which often have many servers that can overheat and will cause major hardware and software issues if turned off in a power failure.

Uninterruptible Power Supply (UPS)

  • A UPS is electrical hardware that provides backup power for a computer system.
  • The UPS is plugged into the wall socket and the computer system is plugged into the UPS.
  • The UPS provides power to the computer when a power outage occurs.
  • Another benefit of a UPS is to keep the power to the computer system at a constant voltage. This prevents power surges which can otherwise damage computer parts.

Environmental Temperature Control or Air Conditioning

  • Computer systems can run hot at times so it is wise to have control of the temperature to prevent overheating.
  • This is most suitable for server rooms and classrooms of computers.
  • Computer systems that run cooler, will run more efficiently leading to better computer system performance.
