TALKING ABOUT COMPUTERS AND THE INTERNET
Since computers were first introduced to the public in the early 1980’s, technology has changed a lot. The first computers were simple machines designed for basic tasks. They didn’t have much memory and they weren’t very powerful either. Early computers were expensive and customers often had to pay thousands of dollars for machines which actually could do very little. Most computers were separate, individual machines, used mostly as typewriters or for playing games.
But time has changed, and computers became powerful machines with countless practical applications. In the civilized world, there is at least one computer in every household, as they do not cost a fortune any more.
Programmers create a large selection of useful programs which do everything from teaching foreign languages to bookkeeping. We are still playing videogames, but today’s games have become faster, more exciting interactive adventures. People can get online and communicate with other computer users around the world, and join international communities online. Social media sites are also very popular. In short, the simple individual machines of the past have evolved into an international World Wide Web of knowledge.
How does a computer work?
Whether you realize it or not, computers play an important role in our lives. When you withdraw cash from an ATM, scan groceries at the store, or use a calculator, you’re using a type of computer. But do you know what a computer is and how it works? A computer is an electronic device that manipulates information or data. It has the ability to store, retrieve, and process data. You can use a computer to type documents, send emails, and surf the Internet. You can also use it to handle spreadsheets, accounting, database management, presentations, games, and more.
