How do computers
work?
Computers
basically work by changing and moving small
electrical charges around an electronic
circuit.
The key to a
computer is that is uses only a yes and no system. This is also
called binary. or I or O. Yes there is an
electrical charge or no there isn't.
Everything a
computer receives and delivers are electrical
signals that are either there or not there. ON or
OFF.
A stream of this
information(IOIOIIIIOOO) can be then changed into
information we can see or hear.
So how do
these charges get about?
 The key component to a computer is a
substance called a semiconductor. This substance is
built into something called a diode or a
transistor. A transistor is a kind of switch that
allows an electrical charge to get through or not
get through.
A computer 'chip'
is made up of thousands, or even millions of these
transistors. The computer chip spends most of it's
time letting electrical charges go from one
transistor to another.

How do the
parts of computers work?
A computer is
made of several basic parts.
- A Central
processing unit (CPU)
- Random Access
Memory (RAM)
- Harddisk
drive
- Read Only
Memory ROM (ROM)
- Input/output
devices
There are a
variety of different types in this group, for
example there are different types/brands of CPUs,
RAM, HD with different abilities like speed and
capacity.

specifics on how these different parts work check

The first Australian
computer was being designed
almost at the same time as ENIAC.
This aussie computer was called
CSIRAC and in many ways was
developed independently to those
in Europe and USA. 
Is the film "The Matrix" a possible
future of how computers become part of our
existance? This idea is taken quite seriously at
