“It’s hardware that makes a machine fast. It’s software that makes a fast machine slow.”

People can play songs, perform their documentation work, surf the internet, check emails, search for your requirements on the internet with great speed and accuracy.

The speed is considered as the biggest advantage of computers because they can perform all operations at an incredible speed which can reduce the amount of time spend when working manually.

For Example, It can calculate the salaries of Employees within a fraction of seconds before it would take long hours when done manually by people.


Not only speed but a computer can work with almost 100% accuracy.

This is also one of its advantages, as it can perform complex numerical calculations not only with speed but with unbelievable accuracy..

Imagine you have given a task to calculate the gross salary of ten thousand employees with reduction as per the rules and regulations of the organization.

That’s not a simple task to calculate the given salaries manually, you are bound to make mistakes and even a small mistake can harm you badly economically.

Virus and Hacking Attacks

Viruses are just computer programs that are designed and developed to harm the computer, steal important information like passwords, pins, and other sensitive information.

Hackers use this program to crack your system down and get unauthorized access to your computer systems, which can damage people economically as well as socially .

One should use legal software, antivirus program, and anti-hacking software while surfing on the net or while online trading which minimizes the hacking and virus attacks.

Data security has been a major concern due to computer viruses and hacking attacks many companies offers services for data security.

Computer Cannot Take Their Own Decision NO IQ

As personal computer [PC] does not have their own IQ they cannot take decisions on their own, which sometimes make our work tedious.

They simply operate when given proper and correct instruction, if computers gets wrong or improper instruction the result will be wrong as they do not have logical brains determining true or false.
