●● the components of a pc designed to perform the function of input,
output, or for external storage.
input: keyboard, mouse, mic.
output: monitor, speakers, printer.
Answer: peripheral devices
●● the connection point on an I/O panel that allows peripheral devices
to be connected to the pc.
m; these are designed for different device types so there are a variety of
types as well.
Answer: port
●● the cutouts housing the ports that allow for the connection of
peripheral devices.
,m; front panel ports: audio, USB. motherboard panel ports; everything
necessary. adapter card ports; whatever necessary for its function.
Answer: I/O (input/output) panel
●● a piece of plastic on the I/O rear panel.
grounds I/O ports to the case. blocks electromagnetic interference. acts
as a dust barrier.
Answer: I/O shield
●● powers PC components with direct current (DC) low voltage power;
must meet the combined power requirements of the components.
m; access is on the tower's rear panel. has a fan exhaust.
Answer: power supply unit (PSU)
●● a static charge on someone's finger or on a tool conducted into a
computer chip that can cause a temporary or permanent fault in the chip.
m; connected through to the PSU to the building's ground system diverts
this charge away from the chip.
Answer: electrostatic discharge (ESD)
,●● energy from magnetic and electrical sources that components are
exposed to that can cause temporary or permanent faults.
m; a pc's case absorbs this energy.
Answer: electromagnetic interference (EMI)
●● has the value of one or zero and is referred to with a "b".
Answer: bit (b), or binary digit
