Mention any two limitations or weaknesses of a computer ?

What are the limitations of computers?

Now I described about your question that,
Limitations of Computer :
Computer cannot operate without the instructions given by humans. It is programmed to work effectively, fast and accurately. Computer cannot think by itself and does not have common sense. It is totally dependent on humans.
Depend on users input.
Computer have no imagination.
Cannot detect error in logic.
Only expert user can work on it.
Cannot take its own decisions.
Some of the limitations of computer are as follows:
No Self-Intelligence
Computer does not have intelligence of its own to complete the tasks. They give wrong output if the input given by humans are wrong. It works according to the instructions given to it by the user.
No Thinking and Decision Making Power
The computer cannot think itself. The concept of artificial intelligence shows that computer can think. But still this concept is dependent on set of instructions. It cannot take any decision. It can only perform the tasks that are instructed by the users.
No Feeling
Lack of feeling is another limitation of computer. A computer cannot feel like us. It does not have emotions, feelings, knowledge etc. It does not get tired and keep on doing its tasks. It can do very risky works which are not capable by human beings.
No Learning Power
Computer has no learning power. Computer cannot perform the tasks without instructions. It cannot read the same instructions time and again. Once the instructions is given it will work for one time. It can solve the problems but it cannot learn the problems. It can only work according to the instructions given.
More, limitation of computer
Computer has done this and that. Actually this is not the computer which has done this but the user. Despite its various features, a computer does have the following limitations:
a. No Self Intelligence
Today, a computer is able to do a work which is impossible for man. Computers are used to do risky and dangerous work and where sharp actually is needed. But it does not have any intelligence of its own. It works according to the instruction only.
b. No Decision-Making power
Computer cannot take any decision of its own. It does only those tasks which are already instructed to it.
c. No learning power
Computer has no learning power. Once you give instructions to a computer how to perform a task, the very task is cannot perform if you do not give it any instructions for the next time. For example, when you are taught how to solve a problem and it same type of problem is given to you to solve, then you can do it because you have learned how to solve the problem.
Thank you for the question. I hope you will be benefit from this answer.
Limitations
1. Computer Assisted Learning is always liable to be
underused. If not implemented and applied properly it may fail to help the
learner achieve learning objectives.
2.Though Computer Assisted Learning creates virtual
atmosphere while teaching science subjects such as Chemistry, Physics, Biology,
etc., students may miss hands on experience which they get in an actual
laboratory.
3. Computer Assisted Learning is quite expensive as compared
to ordinary learning.
4.Learning Content used in Computer Assisted Learning needs
timely and regular upgradation, which again is quite expensive. Delay in upgradation
and development of new content might make the old content useless with the
passage of time.
5. Computer Assisted Learning requires highly efficient
teachers; efficient teachers are exceedingly rare in our country. Inefficient
handling of Computer Assisted Learning apparatus and content may further cause many problems.
