Each time you turn it on, is a tabula rasa that, with appropriate hardware and software, is capable of doing anything you ask. It is a calculating machine that speeds up financial calculations. It is an electronic filing cabinet which manages large collections of data such as customers' lists accounts, or inventories. It is a magical typewriter that allows you to type and print any kind of document-letters, memos or legal documents. It is a personal communicator that enables you to interact with other computers and with people around the world. If you like gadgets and electronic entertainment, you can even use your PC to relax with computer games. (Estbras, Santiago Remacha, 2002: p 4)
