Computer hardware is all the equipment and devices associated with the
operation of a computer system. Everything that is tangible or touchable
regarding the computer is hardware, including the disks used to program the
computer. Hardware is divided into input devices, edit devices, output
devices, and input/output devices.
Practice the following general maintenance procedures to maintain your
computer in peak operating efficiency:
Keep devices clean and free of debris.
Clean the keyboard and button selection areas with a camel hair brush.
Clean optical surfaces with a lint-free cloth or chamois. Check the
operating manual to make sure screen surfaces are not covered with a
glare preventative spectral coating that spray cleaners could damage.
Clean exterior cases, tabletops, and mouse track with a slightly
dampened, lint-free cloth. Dampen the cloth; do not wet the components.
Do not allow food or drink near the keyboard, the mouse track, or the
pressure sensitive and electronic tablets.
Inspect connector ports (COMPORTS) and pins for damage.
Carefully align pins and never force a connection when connecting
