We encounter(сталкиваться) daily many computers thatspring(появляться) to life the instance(пример) they are switched on (e.g.calculations, the car’s electronic ignition, the timer in the microwave, or theprogrammer inside the TV set), all of which use chip technology.What makes your computer such a miraculous(удивительный) device? Eachtime you turn it on; it is a tabular rasa(нетронутое) that,with appropriate(соответствующий) hardware and software, is capable of doing anything you ask. It is a calculating machine that speedsup financial calculations. It is an electronic filing cabinet, which manages large collections of data such as customers’ lists, accounts, orinventories.

It is a personalcommunicator that enables you to interact with other computers and peoplearound the world.
