2. WHAT IS HARDWARE?
Your PC (Personal Computer) is a system,
consisting of many components. Some of
those components, like Windows XP, and all
your other programs, are software. The stuff
you can actually see and touch, and would
likely break if you threw it out a fifth-story
window, is hardware.
4. INFORMATION ON
• mouse probably has at least two buttons on
it. The button on the left is called the
primary mouse button, the button on the
right is called the secondary mouse button
or just the right mouse button. I'll just refer
to them as the left and right mouse buttons.
Many mice have a small wheel between the
two mouse buttons.
• Like the mouse, the keyboard is a means of
interacting with your computer. You really only
need to use the keyboard when you're typing text.
Most of the keys on the keyboard are laid out like
the keys on a typewriter. But there are some
special keys like Esc (Escape), Ctrl (Control), and
Alt (Alternate). There are also some keys across
the top of the keyboard labeled F1, F2, F3, and so
forth. Those are called the function keys, and the
exact role they play depends on which program
you happen to be using at the moment.
• A monitor or display (also called screen or
visual display unit) is an electronic visual
display for computers. The monitor
comprises the display device, circuitry, and
an enclosure. The display device in modern
monitors is typically a thin film transistor
liquid crystal display (TFT-LCD) thin
panel, while older monitors use a cathode
ray tube about as deep as the screen size.
• Computer speakers, or multimedia
speakers, are speakers external to a
computer, that disable the lower fidelity
9. IMPORTANCE OF COMPUTER
HARDWARE AND SOFTWARE
• Every computer consists of hardware and
software. Both the hardware and the software are
very important for the way in which the computer
operates. Any problem that might occur within the
function of computer hardware or software
influences the way in which the computer
functions. This is why it is very important for all
of us to become aware of what our computer
consists of and how its components operate so as
to be able to overcome certain problems that might
occur within our PC. The hardware is considered
the most important part within a computer because
even the software is influenced by it.
I would like to thank my father, mother and
sister for giving me great ideas and for
constructive criticism. I would also like to
thank my teacher for giving me this
opportunity to learn so much.
