The limitations of computers primarily define certain tasks that computers cannot perform, or in which humans perform better than computers.
Computers’ working speed, data storage capacity, reliability, and ability to work day and night without getting tired make them better than humans.
Computers can easily beat humans in terms of speed, accuracy, and memory management, but computers still have some limitations, there are many tasks in that computers cannot perform like humans. And today we are going to talk about these limitations of computers.
Today we will learn in detail what are the limitations of computer. And how humans are better than computers at performing certain tasks.
So without wasting any time let’s understand the limitations of computers.
Limitations of Computer
1) Lack of Common Sense
A computer is an automatic machine that works according to pre-written programs and logic. If the computer is asked to perform a task for which there is no program already fitted in the computer, then the computer will not be able to perform that task.
Computers do not have any common sense, which is one of the major limitations of computers.
There is no doubt that computers are fast, reliable, and efficient but they lack common sense. Computers function entirely based on stored programs or logics.
Since there is no fullproof algorithm designed for computers that can help them program general logic. Computers cannot make sound and rational decisions based on the situation or facts.
Let us understand this with an example. Read the following sentence:
“Suresh is red and the man holding the stick is a nice person.”
This word is based on common sense. If we write this sentence in Word, the computer will not show any error. But any person reading this sentence will say that this sentence is wrong because he has common sense and the computer does not have common sense.
Its correct sentence is given below
“Suresh is a nice person and the wood in his hand is red.”
2) No IQ or Zero IQ
We all know that computers are faster than humans in terms of speed, give accurate results, and are more brilliant than humans but they cannot replace humans because they have zero IQ. Zero IQ means that the computer does not have the brain to do anything on its own. They can’t do anything on their own.
Like us humans, a computer does not do any work on its own nor can it take any decision on its own.
In simple words, computers do not have the ability to think and understand. Which is another main limitation of computers.
Computers can work continuously without stopping but there are some tasks that require suggestions and ideas to do them. Such tasks can be completed only when the person in front has an IQ (Intelligence Quotient).
Since a computer is a machine that works only according to pre-written programs, it lacks intelligence and cannot perform tasks that require suggestions and ideas.
No matter how easy or complex the work is, if the computer does not already have a program for it, it cannot do that work. A computer works only when an instruction or program has already been inserted into it to perform that task.
However, nowadays computers are becoming smarter with time as more instructions are given to them programmatically than before.
3) No Feelings
A computer is a machine. This is not like us humans. Have you ever seen a computer crying? Or has a computer rejected your order or instruction? The answer is BIG NO because there is no emotion in it. They are not able to differentiate between good and bad because they work according to pre-written programs or instructions.
Computers can work round the clock with the same accuracy and speed because they do not feel fatigue, boredom, jealousy, etc.
They do not have their own IQ and cannot make their decisions based on logic. They are completely dependent on humans for input. But nowadays scientists are engaged in making such computers which have the ability to think and feel on their own. An example of this is Sophia, a humanoid robot developed by Hong Kong-based company Hanson Robotics.
4) No Thinking Capability
Computers do not have the ability to think. A computer is a machine which cannot think for itself. These are machines that have been programmed to perform specific tasks.
Computers can not do any work by thinking on their own, they are given instructions to complete that task. A computer without programs is just a box.
However, humans have developed some algorithms to make computers work and think like humans, which is known as Artificial Intelligence. But this concept still depends on the set of instructions and programs which are given by humans.
5) No Decision-Making Ability
Computers cannot take decisions on their own as humans, they cannot take decisions. Decision making is a complex task that usually requires elements such as information, intelligence, knowledge, and judgment ability. Computers lack all these, so they are unable to take decisions. Also, without a power supply, they are simply a dead machine.
Computers are not programmed to make decisions on their own but to work with logic and algorithms. Computers work only on logic. They work only as per the instructions given by the users.
Let us understand this with an example.
For example -: Mohan, Sulekha, Kavita, Simran, Sophia, Ram, etc. are some names. We humans know which name is of a boy and which name is of a girl, but computers do not know which name is of a boy and which name is of a girl because they do not have the ability to take decisions. , They only work according to the pre-given instructions or programs which are given by humans.
6) No Learning Power
Computers do not have the power to learn things from the jump like we humans do, they cannot learn things on their own. They work on the basis of pre-given programs and instructions.
Computers cannot learn the way we humans learn from our past experiences. If we have to get any work done by the computer, then for this we will have to give input again and again, only then the computer will process it on the basis of our input and give the result output.
7) User Dependent
This is the main limitation of computers. Today computers have become quite smart but they still depend on the user to take input. If a computer is not given the necessary data to complete a task, it cannot process that task.
The computer always depends on the user. Without human instruction, computers cannot perform any task. Most situations always require some form of human assistance. It cannot function completely on its own without human intervention because how will the computer produce output unless it receives input?
In simple words, the computer does not do any work until the computer does not receive any instructions from humans. Here instruction means input data received by the user.
Since computers are programmed by humans and follow the instructions that are already fitted in the computer, if those instructions are not accurate then the computer will also not be able to function accurately.
Computer is such a machine that once it is switched on it becomes completely automated. But a computer cannot turn on and off on its own unless it is fed with such a program.
Some modern computers can handle some automated and repetitive tasks on their own but, the user still needs to configure the automated process by monitoring the task process and providing correct data.
8) No Implementation Power
Computers can store large amounts of data and perform complex operations, but they do not have implementation power. This means that computers cannot implement anything on their own.
Let us understand this with an example.
When you type something on Word, you must have seen that if any word is wrong, some red line appears below it and as soon as you click on that word, the option to correct that word comes and that word is correct. It happens.
This means that the computer is unable to implement the wrong word and correct it.
A computer can store a book of law but cannot implement it.
It can store hundreds of guides to solve various problems. But it can solve only those problems for which it is programmed.
9) Cannot Express Ideas
This is also a limitation of computers. Since a computer is a machine and a machine can never express its thoughts. Therefore even computers cannot express their thoughts. Computers work on pre-programmed instructions and given data.
10) Made For Knowledgeable Audience
it is necessary to have knowledge of computer to operate a computer.
Only a person having computer knowledge can use a computer because without computer knowledge you cannot operate the computer. Although it is easy to operate a computer for basic tasks, some complex tasks may require an IT specialist or programmer to work on.
