PRESENTED BY- PRIYA KUMARI CLASS-10th SCHOOL NAME- SHARADHEYA BHAVRAW DEVRAS, SARASWATI VIDYA MANDER MUNGER. COMPUTER SYSTEM Is a collection of entities(hardware,software and liveware) that are designed to receive, process, manage and present information in a meaningful format. COMPONENTS OF COMPUTER SYSTEM * Computer hardware - Are physical parts/ intangible parts of a computer. eg- Input devices, output devices, central processing unit and storage devices. * Computer software - also known as programs or applications. They are classified into two classes namely - system software and application software. *Liveware - is the computer user. Also known as orgwareor the human ware. The user commands the computer system to execute on instructions. CONTACT ME-8340628280 GMAIL-saurabhraj9272@gmail.com ----------------------THANK YOU-----------------------

4. WHAT IS COMPUTER
SYSTEM
1.The word is derived from ‘compute’, which means to
calculate.
2. A Computer is an electronic device that can
perform a variety of tasks by executing a given set of
instructions.
3.It is a versatile and can handle multiple tasks like
documentation, accounting, designing, airlines,
railways and many more.
4. The acronym for COMPUTER is Common
Oriented Machine Particularly Used for Trade and
Education Research.

5. ORGANIZATION OF COMPUTER
SYSTEM

6. CENTRAL PROCESSING
UNIT
A central processing unit (CPU) is the
electronic circuitry within a computer
that carries out the instructions of a
computer program by performing the
basic arithmetic , logical , control and
input/output (I/O) operations
specified by the instructions.

7. MONITOR
1. A monitor or a display is an
electronic visual display for
computers.
2. The display device in modern
monitors is typically a thin film
transistor liquid crystals (TFT-
LCD) thin panel, while older
monitors used a cathode ray
tube (CRT) about as deep as the
screen size.

8. MOUSE
In computing, a mouse is a
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 for fine control of a
graphical user interface.

9. KEYBOARD
1. A keyboard typically has
characters engraved or printed
on the keys and each press of a
key typically corresponds to a
signal written symbol.
2. However, to produces some
symbols requires pressing and
holding several keys
simultaneously or in sequence.

10. PRINTER
In computing, a printer
is a peripheral which
makes a persistent
human readable
representation of
graphics or text on
paper or similar
physical media.

11. MODEM
A modem (modulator-
demodulator) is a device
that modulates signals to
encode digital information
and demodulates signals to
decode the transmitted
information.

12. SPEAKER
Computer speakers, or multimedia
speakers, are speakers external to a
computer, that disable the lower fidelity
built-in speaker.

13. CHARACTERISTICS OF A COMPUTER
1.Speed
2.Accuracy
3.Reliability
4.Storage Capacity
5.Versatility
6.Reduction in Manpower
7.Reduction in Paper Work

14. MEMORY TYPES
1. Computer memory is the storage space in computer
where data is to be processed
And instructions required for processing are stored.
2. Memory is primarily of two types-
* Internal Memory- cache memory and
primary/main memory.
* External Memory- magnetic disk/ optical disk etc.
