LIMITATIONS OF COMPUTERS:-

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

1.        They are unnatural and therefore unintuitive - the natural way for a human to interact with another human is by verbal and nonverbal communication.

2.        Computers cannot think for themselves. They are not intelligent. If some incorrect information is fed into computer, it will result in an incorrect output.

3.        They cannot adequately deal with 'fuzzy' terms, unlike humans who describe most things in a fuzzy way.

4.        A computer can't tell us something completely new; it can only derive something based on something known that it was previously programmed to manipulate. They are not creative or imaginative, nor are they prone to arbitrary moments of genius.

5.        They are unquestioning devices. They do not feel and they do not understand ethics.

6.        Computers can only adequately process information that may be quantised. They cannot adequately deal with abstractions.

7.        The greatest limitation of a computer is that they are engineered, built and used by humans. They expose our flaws and under-sights.

8.        They do not have common sense. We cannot teach it to think morally and ethically.

9.        Its limitations are how much data we put into it. How much memory it has. Its life expectancy is how long the hardware survives. They get replaced easily because as the years passes, the technology and components get better.

10.    They are not smart, innovative and creative.

11.    We cannot expect them to invent, understand human emotions.

12.    A Computer cannot care itself like a human. A computer is dependent still to human beings for this purpose.

13.    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 cannot

14.    This is an area where the computer simply excels—one mainframe system boasts 700 pages of raw output per night (while translators are sleeping), and other systems are equally prodigious. How raw the output actually is—and how much post-editing will be required, another factor of speed—will depend on how well the computer has been primed to deal with the technical vocabulary of the text being translated. That way computer is dependent on human being.
