  The second thing which changed the world is computer

  Computers have changed the world in many ways.  They allow huge amounts of information to be stored in a small space.  They also allow a person to calculate mathematical problems with ease.  Finally, computers allow people to communicate with one another through internet sites such as Facebook, My Space, and Twitter. Personal computers today can hold up to 32 gigabytes of memory.  They can be used to store music, pictures, documents, videos, and much more.  Computers are able to be reprogrammed to suit any user's needs.  This is one of the key traits of a computer today. Computers were first designed to help a person calculate numbers; this function can be seen as far back as 2000 B.C. with the use of the abacus.  Modern computers are simply very advanced calculators.  Almost any mathematical function can be plugged into a computer, and the computer will solve almost instantaneously.  The use of a computer as a calculating device takes away the monotonous task of calculating by brute force. Finally, computers have changed the way that we communicate as a society.  People can now talk to one another in almost no time at all through the use of social networking sites, and people can even live video chat with applications such as Skype.  Imagine, if this idea had been presented to scientist 50 years ago, the presenter would have been laughed out of the conversation.
