Computer

                         

After so many inventions and discoveries, Humans finally made computer. And, today there are some people in the world who can't live a bit without computer or mobile phone.

                     

Computer means system device used for doing large processes and calculations in less time. Computer system works by 0,1

                 

0,1 is called as binary language of computer. Any computer or system device can work properly because of using Binary language.

                           

There are so many important components of computer. Because of so many components work at same time, computer system works properly.

                                                         

Any computer is dependent on the following components:

1) RAM

2) ROM

3) Processor

4) Display

                                           

                                                       

Computer are mainly used in office works, Home works, Construction works and so many things. Computers are also used in various organisations and companies. Millions of people use internet for their daily work like - Making presentations, Making documents, Tables.

                                                                   

If we connect internet with our computer, then we are connected with all world. And we know that, if we connect to the internet, then we are connected to the all world.

                                                       

After connecting internet to the computers, we can access any site on the internet with the help of computer. Also, we can access all social media like sites with the help of computer.

                                         

Millions of people uses internet for the educational purposes. We can get the information of anything or any matter with the help of computer. With the help of computers, we can complete our any project easily.

                                               

There are some disadvantages of computers too.

After using computers for long time, our body can have the harmful effects on it. If we use computers  6 to 7 hours daily, then our Neck can have the harmful effect.

                                               

We can have Brain tumor disease because of large use of computer. Also, we can get distracted because of computers in studies.

                   

So, We should use computers for less time and for good purposes. And we should not use the computers for very long time.
