2. Computer hardware
• What is computer hardware and how does it
work?
Computer hardware is any physical components
used in computing
Many computer components work together to
make up a computer
Computer hardware uses software and binary to
communicate to other hardware which allows the
components to work with each other
3. Computer hardware
• How is computer hardware developing?
Too put it simply, it is getting faster and
smaller
4. Motherboard
A motherboard
looks like this.
The mother board is the
centre part of the
Computer.
It holds the
Components and connects them together with a
series of circuits and chips . This is also helps power
each component

system that allows installation from the USB
• The bios will allow a boot from USB which
when loaded with the windows 7 operating
system software will start a installation
• USB 3.0 is preferred version to use when
installing with USB because of the superspeed
transfer mode
52. Step 1:
