What Are The Limitations Of A Computer ?

The computer can outperform human beings in speed, memory and accuracy but still the computer has limitations. There are following limitations of a computer.

Programmed by human:
Though computer is programmed to work efficiently, fast and accurately but it is programmed by human beings to do so. Without a program, computer is nothing. A program is a set of instructions. Computer only follows these instructions. If the instructions are not accurate the working of computer will not accurate.

Thinking:
The computer can not think itself. The concept of artificial intelligence shows that the computer can think. But still this concept is dependent on set of instructions provided by the human beings.

Self Care:
A Computer can not care itself like a human. A computer is dependent still to human beings for this purpose.

Retrieval of memory:
A computer can retrieve data very fast but this technique is linear. A human being's mind does not follow this rule. A human mind can think randomly which a computer machine can not.

Feelings:
One of the main limits in the computer is of feeling. A computer can not feel about some like a human. A computer can not meet human in respect of relations.

Human can feel, think and caring but a computer machine itself can not.

A computer can not take place of human because computer is always dependent of human.

The limitations of computers can be better explained in terms of artificial intelligence which considers computers as machines which lack analytical skills possessed by the humans. Computer is still a machine and is programmed by the programmers. It lacks the ability to take cognitive and analytical decisions by its own. Scientists are investing lots of money and efforts to develop intelligent devices which can perform cognitive tasks as smart as humans do. However computers have the edge over the other devices in simultaneous processing of tasks. One of the limitations also includes machine failure in the case of some hardware or software problem. The computer sometimes malfunctions and results in loss of data if some virus attacks or in the case of power failure. They are also costly to purchase and have higher maintenance costs which can also serve as major limitation.

Computers are machine which can operate according to instructions given by humans through computer programs. If instructions or softwares are not installed in computer, computer cannot work and If those instructions or softwares are not designed to meet our requirements, the  we cannot benefit from computers. Computers doesn't posses their own brain, they can only work as designed and might sometimes not meet users' requirements.

Capabilities are,

1. Can solve complex calculations quickly which takes a long time to solve manually

2. Capable of handling and processing large calculations at a single time

3. All Electronic Items have some form of Computing functions.

Limitations are,

1. Cannot replace a Human Brain

2. Works only on Stored Procedures and cannot think on its own.

3. Not all complex calculations can be solved through computers

4. Cannot depend on computers all the time

A computer can not take place of human because computer is always dependent of human.Definition Of Computer:   A  Computer is a device that computes, especially a programmable electronic machine
that performs high-speed mathematical or logical operations or that
assembles, stores, correlates, or otherwise processes information.
