Limitations Of Computer

We think computer is more intelligent than human being but actually it is just a machine that follows the user commands / instructions. It is programmed in such a way that it gives the correct information to the user. Having a lot of best features such as speed, accuracy, versatile, diligence, automatic and electronic it lacks something among which some of them are shortly described below.

Limitations / Lack of Computer

1. No. IQ

Computer is a dumb machine. Nowadays, computers are doing very risky jobs with its great speed and accuracy but it can not do any work without instructions from the user as it does not have its own intelligence. It is the user who decides what to do and in what sequence.

2. No Feelings and Emotions

Computer does not have feelings, emotions, taste, knowledge and experience like human beings. Thus it does not get tired and bored of doing the same task repeatedly for many hours. It does not distinguish between the users but its speed and performance may depends upon its capacity. 

3. Lack of Decision Making Ability

Computer does not have its own intelligence to make any decisions. As a machine it can not find the difference between any things neither it can correct the mistakes by itself. It needs the help of the user to correct the mistakes and so on. 

4. No Heuristics

Computer being an intelligent machine it lacks the characteristic of learning from other and its past experience. As a human being we can learn from others and our past experience but the computer can not do so.

History Of Computer In Nepal

The history of computer in Nepal, dates back to 2028, B.S. (1972 A.D) when a Second Generation IBM 1401 computer was initially hired on rent by The Government of Nepal, paying Rs. One Lakh Twenty Five Thousand per month to use in the census of that year. After that the computer was purchased by the government for further data processing in Bureau of Statistics.

                   
                  Later in 2031, B.S. (1975 A.D) Electronic Data Processing Center (EDPC) named as "Yantrik Sarinikaran Kendra" in Nepali language was established in the capital city which is nowadays called National Computer Center (NCC). Another British model computer called ICL 2950/10 having 64 terminals was purchased for the census of 2038 B.S.

Introduction Of Computer

The word computer has been derived from the Latin word "Computare" which means to calculate. Computer is an electronic man made programmable machine that first takes input from user through its input devices, process it to produce meaningful information in human understandable language/form and even can store the data and information for future use in its storage devices as per the user requirements.

All the modern computer works by following the principle of IPOS (Input Process Output and Storage) cycle. The IPOS cycle has been described shortly below:-

a) Input:

The raw data and instructions which are given to the computer for processing is called an input. Input can be given in any form such as text, numbers, letters, characters, symbols, audio, images, etc. Input are given to the computer through its input devices such as mouse, keyboard, scanner, light pen and many more. 

b) Process: 

An action taken upon input data to produce the meaningful information as an output in human understandable language is known as processing. The processing is done by the Central Processing Unit of a computer. CPU is also known as the brain of computer.
