Computers have changed the way we do everyday things, such as working, shopping and looking for information. We design houses with the help of PCs; we buy books or make flight reservations on the Internet; we use gadgets that spring to life the instant they are switched on, for example the mobile phone, the music player, or the car ignition, all of which use microchips.
Many people now work at home, and they communicate with their office by computer and telephone. This is called ‘teleworking’.
With the appropriate hardware and software, a PC can do almost anything you ask. It’s a magical typewriter that allows you to type and print any sort of document. It’s a calculating machine that makes financial calculations. It’s a filing cabinet that manages large collections of data. It’s a personal communicator that lets you interact with friends. It’s a small lab that helps you edit photos and movies. And if you like electronic entertainment, you can also use it to relax with games.
