There is no doubt that people of our information-dependent society should be computer-literate. They must understand that computers can greatly influence the quality of life.  

There was a time when only priviliged people had an opportunity to study the basics, called the three R's: reading, writing, and arithmetics.  

Computer literacy is the ability to use computers and related technology efficiently from elementary use to programming and solving of advanced problems.    

As personal computers become commonplace and they become more powerful, the concept of computer literacy is moving beyond basic functionality to more powerful applications under the name of multimedia literacy or new literacies.

Commоnly recognized examples of new literacies include such practices as instant messaging, blogging, maintaining a website, participating in online social networking spaces, podcasting and videocasting, photoshopping images and photo sharing, emailing, taking part in online discussion, etc.
