Definition of computer:
The word computer comes from Latin computare which means to
calcite so normally computer can be consider as calculation device that
can perform calculation at enormous speed.
Computer can be defining auto matics mechine which takes input from
user process it store it neassary and give output in desired from.
Characteristics of computer:
Speed: The
speed of computer is very fast which can in a few second. The amount
of work that a human being can do in an entire year can be done by
computer in no time. The speed of computer is measure in fraction of
second speed of computer always l
Word Length:
The word length or size refers to the number of bites that CPU can
manipulate at one time. It is based another size of rejecter in the CPU
and the number of data lines in the data bus.
Automatic:
Everything given to computer is process and done by computer.
According and given data that computer works itself without interaction
of users. As job is started in carries out until the job finished which
makes computer Automatic.

Versatility:
A computer can perform more than one work having different
character. Such character is known as versatility. Computer is capable of
performing almost all tasks at the same time. These devices used in
different application area such as education, business, hospital etc.
DILIgeanc
Computer is freest tried of monotony so can work par an hour without
grumbling due to this property computer is able to perform the work
reptile which is known as Diligeance.
Non-inteiiigent:
Computer cant do simple work if its not given input of data &
instruction everything that computer does is behind the sense of human
being so computer is called brain-less idiot.
Advantage Of computer:
# Computer is always 100% accurate.
#computer is much faster than man.
#it is much more important Reparative job.
#it can perform many work at time.
# it is used for general purpose and multiple fields.

Computersystem:
The design Arrangement construction or organization different parts of
a computer system are known as computer archicture.
The physical arrangement of the computer associate
together for the world is known is as computer system a computer is
divided in two following element.
Hardware:
Hardware is a physical part of the computer which is contained and
tangible is known as hardware monitor, mouse, ram and keyboard.
Software :
Software are the terms use to descried that is truncation that tell the
hard ware what and how to perform a task software nontangible e.g.
MS office tall etc.
Data and information:
Data can be considers as the raw facts that does not provide sensible
meaning whereas information are manly plate data at provide sensiblemeaning.

Input:
Input unit reads the data and instruction from the user convert
them in too computer understandable form into the processing
unit. Input unit links external Enverment with the computer
system keyboard mouse light pen are the example.
Output:
Output supply the information obtains and result of data from
the outside of the world in takes the information and result
from the processing unit and present into the user understand
able from monitor printer speaker etc.
Processing unit:
CPU build in single chips is known as processing unit.it is also
known as CPU and is mounted in mother board processing unit
has two sub unit.

2) Secondary memory:
This memory also known as auxiliary storage or backup storage.
These memory storage result data and information permantly
and for feature extended so, are non-volatile in neuter before
reading the data and result should be loded in primary memory
first e.g. hard disk cd,dvd flash drive etc.
Microprocessor:
A CPU build single chip is known as microprocessor. A
microprocessor is an electronic device which in interface with
memory and several device microprocessor can be consider as
brain of computer because it devices every things to the
computer for the result it also doesnt the brain of human that itcontrols stores and process with different unit like register array
contract unit some character that different microprocessor from
each other.

ACKNOWLEDGEMENTIts my great pleasure to submit a project report to Narayani Public
HIGHER SECONDARY SCHOOL in the partial fulfillment of requirements
for +2 programs of HSEB.I am glad to study and know about different
programs. This helped to develop lo0gic in different logical statement.
I would like to express my gratitude from the inner core of my hearts to
our computer teacher and our college who helped us to prepare this
project more efficiently. Without those encouragement and support we
wouldnt have completed this project report successfully.
My special thanks goes to Mr. Amit Bhusal, our computer teacher for
his support, suggestion and his help during preparation of this project.
I have tried hard to make my project work better and error free as far
as possible. I have consulted many books and web sites to prepare this
project.
I hope our endeavors will be rewarded well.
