1. WHAT IS COMPUTER
an electronic device for storing
and processing data, typically
in binary form, according to
instructions given to it in a
variable program.

TYPES SPECIFICATIONS
1 PC It is a single user computer system having moderately powerful
microprocessor
2 Workstation It is also a single user computer system, similar to personal
computer however has a more powerful microprocessor.
3 Minicomputer It is a multi-user computer system, capable of supporting
hundreds of users simultaneously.
4 Mainframe It is a multi-user computer system, capable of supporting
hundreds of users simultaneously. Software technology is
different from minicomputer
5 Supercomputer It is an extremely fast computer, which can execute hundreds of
millions of instructions per second.

3. THE BASIC PARTS OF A COMPUTER SYSTEM ARE:
1 Monitor.
2 CPU (Central Processing Unit).
3 Keyboard.
4 Mouse.
5 Speakers.
6 Printer.

4. A television receiver used in a studio to select or
verify the picture being broadcast from a
particular camera.

5. A central processing unit (CPU), also called a central
processor, main processor or just processor, is the electronic
circuitry that executes instructions comprising a computer
program. The CPU performs basic arithmetic, logic,
controlling, and input/output (I/O) operations specified by
the instructions in the program.

7. A Central Processing Unit ( CPU) is the main
microchip in a computer, while a CPU fan is the
dedicated fan that helps keep the processor
cool. Processors generate heat from internal
electrical energy.

8. A floppy disk, also known as a floppy, diskette, or
simply disk, is a type of disk storage composed of a
disk of thin and flexible magnetic storage medium,
sealed in a rectangular plastic enclosure lined with
fabric that removes dust particles. Floppy disks are
read and written by a floppy disk drive (FDD).

9. A keyboard is one of the primary input devices
used with a computer. Similar to an electric
typewriter, a keyboard is composed of buttons
used to create letters, numbers, and symbols,
and perform additional functions. The following
sections provide more in-depth information and
answers to some of the frequently asked
questions about the keyboard.

10. A computer mouse (plural mice) is a hand-held
pointing device that detects two-dimensional
motion relative to a surface. This motion is
typically translated into the motion of a pointer
on a display, which allows a smooth control of
the graphical user interface of a computer

11. Speakers are transducers that convert
electromagnetic waves into sound waves. The
speakers receive audio input from a device such
as a computer or an audio receiver. This input
may be either in analog or digital form. Analog
speakers simply amplify the analog
electromagnetic waves into sound waves.

12. A printer is an output device that prints paper
documents. This includes text documents,
images, or a combination of both. The two most
common types of printers are inkjet and laser
printers.
