The computer memory is like that it stores each and every bit of data input in it at any time and it can store it for unlimited period of time.You can imagine a computer that stores the history of the world and all what happened in past and what is happening in the present and you keep on recording things and events in it for one million years and after that the human at that time can read all that history by pressing one or few keys on computer keyboard, yes sir it is still remembered by the computer at that time.

Remembarance of a Computer:
The fifth point is very important and it is remembering power of a computer, what you can say is that a computer can have unlimited rememberance without any doubt of loss of any information.Consider a human or may be consider yourself and ask a simple question from yourself do you remember all of the things that happened to you starting from the day that you were born.The answer is that no you don`t remember each and every single thing.But think and imagine that if you had the rememberance power of a computer like a hard disk memory.Now when you have the rememberance power of a computer you can answer that yes may be you could remember each and every thing that happened to you since the day you were born.

The versatility of a computer:
The fourth point is the versatility of a computer machine.It simply means that we can open a couple(a lots of applications will slow down an ordinary computer machine so we are talking about a few applications oppened at a time on a computer machine) of applications at a time on a computer machine, what you can say that a computer can prepare the results of schools or college students and at the same time you can print electricty bills with it and at the same very time you can play a song on it and side by side you can play a computer game on it.All that is done by mutitasking property of computer in which the processing of the applications are done in a mutitask manner.

The deligence in computer:
The second point is that there is deligence in computer.We all know that all living things have feelings and a life cycle of their own like most of them they sleep at night, eat food and get worried,get happy etc.But being a machine the computer has no feelings ,it does not need to sleep,itnever gets worried and it has no emotions at all so it never gets happy too or never cries etc.And there is one other thing too that differentiates it from living beings and that is that it never gets tired and never looses its concentrations so if we perform billions of arithmetic from it, it will do all that stuff like the same way from start to end, what I mean to say that it will not get tired in the middle of billions of calculatins or arithmetics.I think that is much for deligence.

The one line conclusion:
Lets take a look that what are those technological weaknesses, I am not going to number each of it but I will point to it using a simple example.Lets say a programmer writes a computer programme and the language he or she is using has its own weaknessen and limitations so the picture we get as a result shows us a computer programme that has addopted the weaknesses and limitations of language itself and as a result the programme produces errors at some points when used in fully operational enviorment.The one line conclusion is that the computers are better accurated than human but are not fully perfectly accurated so that they never ever make any miske or produce an error.

Is computer responsible for all?
But these mistakes and errors are because of humans rather than computer itself , what I mean to say that a computer can make mistakes and produce errors too but all these mistakes and errors are human generated like somebody enters a wrong name in result card record of a student or enters wrong and mistaked marks in marks record and thus the result produced by computer is in error like the result is a wrong name or mistaked marks on result card.But wait a minutes dude is it the human every time that is reponsible for mistakes or are there other reasons too? The answer is yes there are other reasons too like technological weaknesses.

Calculating the conclusion:
So now i made a point that humans can be errorfull, so where do we go from here? Yes,conclusion is that a computer as being an accurate machine never ever makes mistakes and errors like humans do.You can check it out by replacing a computer with a clerk in a school or college office and check the difference yourself.But we must not forget that there nothing in this world without errors what I mean to say that nobody and nothing is so perfect so why computers are so perfect ? are they really perfect ? or may be sometimes they make mistakes too? The answer to these questions is that computer may be make mistakes and produce errors.
