Computer Basics
To work on a computer you should know
about its various devices and their
functionality.
This simulation will teach you the basics of
the computer. It will familiarize you with
the various hardware devices of the
computer like mouse, keyboard, monitor,
printer etc.
A computer is an electronic device that automatically accepts
stores manipulates data and gives the output.
This is the keyboard. It's an input device through which you can
key-in the information. It is the main communication tool for
entering data into a computer. A computer keyboard looks very
much like a typewriter keyboard but has extra keys for specific
computer functions.
This is the mouse again an input device. It is used to give
instructions
to the computer by way of clicking or double-clicking or dragging.
It is
moved around on the desk to control cursor movements draw or
move
text and other objects on the screen. It has buttons that are used to
select options.
Pressing left mouse button once is
called clicking.
Pressing left mouse button twice is
called double-clicking.
Moving the mouse while holding down the left
mouse
button is called dragging.
This is the monitor. It is an output device. The monitor is a device with a
screen where you see what you have typed-in and it is how the computer
communicates with you. It is also called Visual Display Unit (VDU).
Printer is the hardware device you need to produce
"hard copy" or a printed-paper version of the
information from the computer.
Hard disk is a fixed disk
installed inside the computer.
It has very high capacity for
storing information and is
very efficient to use. For any
serious work it is more
practical to have a hard disk
on your system and all new
PCs now have them.
These are various types of external storage devices.
Disks are used for storage of computer-based data and programs.
Most disks have a form of magnetic coating on which data is recorded.
External disks can be carried around.
Programs and data can be stored on floppy disks and then
loaded into a computer for use. Because floppies are portable
they are good for back ups and for moving data around -from
home to office for example. There are two types available for
the PC: 5.25" and 3.5". The smaller ones are more robust and
have a higher storage capacity thus they are now much more
common. Floppy disk drives have a slot into which a disk can
be inserted.
A CD can store very large amounts of data - up to several
hundred megabytes -hundreds of times more than a floppy
disk. It is used for storing large amounts of data that will
never need to be changed. A CD-ROM is inserted into CDROM drive.
Zip disk is also an external storage device.
The zip disk stores data in compressed
form thus can store a large volume of data.
A Zip Disk is inserted into Zip drive.
The microchip is the heart of computers that actually does the work.
It is also known as the processor or CPU (central processing unit).
It is installed on the motherboard inside the computer. There are
different types of processors available in the market.
This is the sound card. A
sound card translates from
digital data into analog
sound and vice-versa. It
can either be used to play
sound that have already
been recorded via speakers
or it can be used to record
sounds digitally on your
computer either from a
microphone or from some
other audio source.
Modem is both an input and output device. The word Modem
comes from Modulator Demodulator. It is a hardware device
that allows computers to be linked using telephone lines.
A modem converts digital signals from computers into analog
signals that can be sent down the telephone and then back
again at the other end.
This is the opening screen of
Windows Me.
