Over the years science has improved and man went on making more and more inventions. Now the question arises which is the best invention......I would consider computers to be the best invention of mankind. Over the years the computers have been improved upon to give us what we know as computer now. Imagine a single day in our life without these devices.....impossible. Everything absolutely everything is possible using the computers, be it talking with your dear ones living far away, or studying for exams, you can even do your shopping using computers. So till date I would say Computers are the best invention ever made by man.
