Computer Hardware Questions and
Answers Graded A+
Case (Tower or Chassis) ✔✔Covers and protects all internals parts from the outside
environment(skin)
Motherboard ✔✔The circuit board that houses most of your computers components and directs
data traffic to and from the appropriate devices (skeleton/ central nervous system
Central Processing Unit (CPU) ✔✔Carries out all complex calculations to perform instructions
sent by the user or input devices and then sends processed data to output devices. CPU speed is
measured in Hertz(brain)
Heat Sink ✔✔Metal block which mounts on top of the CPU in order to cool the processor by
dispersing heat. Most have fans (sweat)
Memory(RAM- Random Access Memory) ✔✔Where the CPU stores temporary data used to run
programs. When the (blank) is full, the CPU redirects the excess data to the hard drive which
isn't as fast. More (blank)= more applications can run simultaneously with no loss in speed.
(short-term memory)
Video Card (Video Adapter) ✔✔Sometimes integrated into the motherboard, this device gives
the system display capabilities. Converts data into a video signal to be sent to a display device.
High quality (blank)s include their own processor and memory. (eyes)
Network Card (Network Adapter) ✔✔Usually a modem (phone jack) port and Ethernet port
PCI Slots (Peripheral Component Interconnect) ✔✔Allows sound cards, video cards, TV/radio
tuners, and modems to communicate with the processor. These devices include connects on the
back of the computer.
Power Supply Unit (PSU) ✔✔Funnels power to all other parts of the computer such as the
motherboard, CD-ROM drives and other peripherals. It also has a fan to cool all internal
components. (heart)
Universal Serial Bus(USB) ✔✔A port on the computer in which many peripheral devices can be
connected such as printers, scanners, cameras, mmp3 players, phones storage devices, etc...
Sound Card (Sound Adapter) ✔✔A separate card you can plug into a PCI slot in order to get
better sound that is provided by the integrated sound chips. (ears)
Basic Input/Output System (BIOS) ✔✔Performs system checks at boot-up time of the computer.
It also provides communication between the processor and peripherals. A mini-, built-in
operating system. (Waking up)
PS/2 ports ✔✔Ports to connect a mouse and a keyboard(color-coded)
Parallel ports ✔✔A port to connect a printer or scanner
Peripherals ✔✔Anything connected to the motherboard or computer such as mice, keyboards,
monitors, sound cards, video cards, network cards, printers, scanners, cameras, storage devices
etc...(arms and legs)
hard drive ✔✔High capacity storage devices used to store the operating system, applications,
and other data. Info is stored on magnetic disks. (long-term memory)
Optical Drives ✔✔CD-ROM, CD-R, CD-RW and DVD-ROM, DVD+/-R, DVD+/-RW drives
used to read high capacity storage media. R= recordable and RW= recordable/rewriteable
Ribbon Cable (multi-wire planar cable) ✔✔A series of parallel, connected wires used to connect
disk drives to disk drive controllers. Red wire goes on Pin 1.
