Introducation to computer [www.studysharebd.com]Rafiq Azad
Computer is an advanced electronic device that takes raw data as an input from the user and processes it under the control of a set of instructions (called program), produces a result (output), and saves it for future use. This tutorial explains the foundational concepts of computer hardware, software, operating systems, peripherals, etc. along with how to get the most value and impact from computer technology.
Audience
This tutorial has been prepared for beginners as well as advanced learners who want to deal with computers. The tutorial is also very useful for undergraduate students of computer science, engineering, business administration, management, science, commerce and arts, where an introductory course on computers is a part of curriculum.
After completing this tutorial, you will find yourself at a moderate level of expertise in the knowledge of computer basics from where you can take yourself to the next level.
Prerequisites
Knowledge of computers is not a prerequisite to follow the contents of this tutorial. This tutorial assumes no background in Computers or Computer programming.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

§ The word computer comes from the word “compute”,
which means, “to calculate”
§ Thereby, a computer is an electronic device that can
perform arithmetic operations at high speed
§ A computer is also called a data processor because it can
store, process, and retrieve data whenever desired

1) Automatic: Given a job, computer can work on it
automatically without human interventions
2) Speed: Computer can perform data processing jobs
very fast, usually measured in microseconds (10-6),
nanoseconds (10-9), and picoseconds (10-12)
3) Accuracy: Accuracy of a computer is consistently high
and the degree of its accuracy depends upon its design.
Computer errors caused due to incorrect input data or
unreliable programs are often referred to as Garbage-
In-Garbage-Out (GIGO)

4) Diligence: Computer is free from monotony, tiredness,
and lack of concentration. It can continuously work for
hours without creating any error and without grumbling
5) Versatility: Computer is capable of performing almost
any task, if the task can be reduced to a finite series of
logical steps
6) Power of Remembering: Computer can store and
recall any amount of information because of its
secondary storage capability. It forgets or looses certain
information only when it is asked to do so

to do. It cannot take its own decision in this regard
8) No Feelings: Computers are devoid of emotions. Their
judgement is based on the instructions given to them in
the form of programs that are written by us (human
beings)
