Hello everyone,
I love to repair computers, but what I really love is
to teach others how to understand/repair computers. I attempt to
simplify any kind of explanation so that even the novice can understand
what I’m teaching. Here is how I teach/explain the seven major computer
components:
1) Motherboard
The motherboard is the heart of the computer.
Every other computer part either sits on, or connects to, the
motherboard in some way. The motherboard is the rectangular colored
board that sits at the bottom of the case.
2) CPU
The CPU (Central Processing Unit) is the brain of the computer.
It runs the software and processes the data that you are working on.
The CPU sits on top of the motherboard and is covered up by a heat sink
and cooling fan.
3) RAM
RAM (Random Access Memory) holds or remembers the data of the software that you are currently running.
The RAM modules (“sticks”) are long and thin and look like a short
ruler. Each RAM module snaps into a corresponding slot on the
motherboard.
4) Video Card
The video card creates the images that appear on the computer monitor.
Almost all modern day video cards attach to either the AGP (Accelerated
Graphics Port) slot, or to the PCI Express (Peripheral Component
Interconnect Express) slot on the motherboard.
5) Power Supply
The power supply supplies the power that the computer needs.
All wires going from the power supply go either directly to the
computer components or to the motherboard. The power supply sits at the
top of the case.
6) Hard Disk Drive
The Hard Drive holds all of your information (even when the computer power is off).
When you turn on the computer, the software and data load from the Hard
Drive into the RAM. The Hard Drive slides into the Hard Drive bay in
your computer case.
7) Optical Drive
The optical drive uses a laser to read (play) or write (record, burn) CDs and DVDs. The optical drive sits in the front bay of the computer.
