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:
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.
No Decision-Making power
Computer cannot take any decision of its own. It does only those tasks which are already instructed to it.
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 if same type of problem is given you to solve, then you can do it.
Computers are emotionless. They do not have emotion, like dislike feelings. They are simply machines
which work as per the instruction given to them.
Curtail human Capabilities
Although computers are great help to human beings, it is commonly felt that we people have become so
dependent on calculator that we cannot make very simple calculation without calculator. Sometimes, find it
difficult to instantly speak out even that telephone number which they use every now and then as they have
got the habit of using them by retrieving the storage.
Excessive use of computers is causing various type of health injuries such as cervical and back pain, pain
in eye, headache.
