The document provides an overview of computers, including what they are, their main uses, and their key components. A computer is a programmable machine that is now ubiquitous in daily life. Computers are used to store documents, photos, communications and more. The main parts of a computer are the system unit, keyboard, monitor, speakers, mouse, and microphone. The system unit contains the central processing unit and other electronic components. Over time, computers have become smaller yet more powerful, going from room-sized early computers to today's personal devices.

2. WHAT IS THIS ?
• A computer generally means a
programmable machine.
• We are all familiar with what a
computer is in a specific,
contemporary sense. Personal
computers (PCs) are found in most
aspects of daily life, and for some it
is hard to even imagine a world
without them.

3. FOR SERVING ?
• Either your tasks to
your tasks will be
better if you write on
a computer
• A computer is
used to save the
phones from your
friends, their
homework, work
on your mom and

girlfriend.

4. PARTS

5. SYSTEM UNIT
• The system unit is the core of a
computer system. Usually it's a
rectangular box placed on or
underneath your desk. Inside this
box are many electronic
components that process
information.
• The most important of these
components is the central
processing unit (CPU), or
microprocessor, which acts as the
"brain" of your computer.

6. KEYBOARD
• A keyboard is used mainly for typing
text into your computer. Like the
keyboard on a typewriter, it has
keys for letters and numbers,

7. MONITOR
• A monitor displays information in
visual form, using text and graphics.
The portion of the monitor that
displays the information is called the
screen. Like a television screen, a
computer screen can show still or
moving pictures.

8. SPEAKER
• Speakers are used to play sound.
They can be built into the system
unit or connected with cables.
Speakers allow you to listen to music
and hear sound effects from your
computer.

9. MOUSE
• A mouse is a small device used to
point to and select items on your
computer screen. Although mice
come in many shapes, the typical
mouse does look a bit like an actual
mouse.

10. MICROPHONE
is a hardware
peripheral originally
invented by Emile
Berliner in 1877 that
allows computer users
to input audio into
their computers.

11. Computers have
become the most
important tool of
man. With them
you can do
something as
simple as writing a
letter or something
as complex as
controlling the
travel of a space
rocket traveling.
