Fundamental of Computer

Computer comes from a Greek word “Compute”, which means Calculation.

Computer is an electronic device, which receive data in its input, process and stores in its own memory and give us require result in need and a clear format. Computer is a high speed electronic device. It is able to do different types of mathematical and logical function.

C: – Commonly

O: – Operating

M: – Machine

P: – Particularly

U: – Used For

T: – Technical

E: – Education

R: – Research.

Computer is a commonly operating machine which particularly use for technical education research.

A Computer is an electronic machine, operating under the control of instructions stored in its own memory, which can accept data (Input), manipulate the data according to specified rules (Process), produce results (Output), and store the results for future use.

“Charles Babbage is the father of Modern computer.”

Computer used for:-

The main reasons for computer using are:-

• To avoid mistakes.
• To store data easily.
• To save time by quick performance.
• The Results is in need and clear format.

Advantages & Disadvantages of Computer:-

• Advantages:-

Following list demonstrates the advantages of computers in today’s arena.

1. High Speed:-

• Computer is capable of performing calculation of very large amount of data.
• The computer has units of speed in microsecond, nanosecond and even the picoseconds.
• It can perform millions of calculations in a few seconds as compared to man who will spend many months for doing the same task.

2. Accuracy:-

• In addition to being very fast, computers are very accurate.
• The calculations are 100% error free.
• Computers perform all jobs with 100% accuracy provided that correct input has been given.

3. Storage Capability:-

• Memory is a very important characteristic of computers.
• A computer has much more storage capacity than human beings.
• It can store any type of data such as images, videos, text and many others.

4. Versatility:-

• A computer is very flexible in performing the jobs to be done.
• This machine can be used to solve the problems related to various fields.
• At once instance, it may be solving a complex scientific problems and the very next movement it may be playing card game.

5. Reliability:-

• Modern electronic components have long lives.
• Computers are designed to make maintenance easy.

• Disadvantages:-

1. No I.Q:-

• A Computer is a machine that has no Intelligence to perform any task.
• Each instruction has to be given to computer.
• A computer cannot take any decision on its own.

2. Dependency:-

• It functions as per a user’s instruction, so it is fully dependent on human beings.

3. Environment:-

• The operating environment of computer should be dust free and suitable.

4. No Feeling:-

• Computers have no feelings or emotions.
• In cannot make any judgment based on feeling, taste, experience and knowledge unlike a human being.
