External and Internal Computer Components
Internal Hardware
1. Motherboard-Contains all of the connections
that allow the carious other subsystems to interact.
2. Central Processing unit (CPU)-The components that performs all calculations and
mathematical manipulations in a computer.
3. Read Only Memory (ROM)-The memory that
computers use to store data and instructions
needed by the CPU for computer operation.
4. Disk Drive-Allows a computer to play CD’s or
DVD’s.
5. Battery-The battery allows your computer to
function. Without a battery you would not be able
to turn on.

everything to work.
8. Fan-The fan is a device that helps your
computer cool down a lot easier by blowing around
the air in your laptop.
9. Heat sink- Necessary to have a CPU cooler.
Without it, your CPU will quickly burn itself out.

computer systems to form a local area network.
15. Serial Port-A connector by which a device that
sends data one bit at a time may be connected to a computer.
16. Random Access Memory-The most common computer memory.
