Комплексный тест по дисциплине «Английский язык» для специальностей среднего профессионального образования Вариант 1 Чтение 1. Текст “Different Types of Computers” … as I’ll explain to you now, computers can be divided into five main types, depending on their size and power. There are: mainframes, desktop PCs, laptops, tablet PCs and personal digital assistants, or PDAs. Mainframes are the largest and most powerful computers. The basic configuration of a mainframe consists of a central system which processes immense amounts of data very quickly. This central system provides information and computing facilities for hundreds of terminals connected together in a network. Mainframes are used for large-scale computing purposes in banks, universities and big companies. PCs, or personal computers, carry out their processing on a single microchip. They are usually classified by size and portability. A desktop PC is designed to be placed on your desk. It is used as a home computer or as a workstation for group work. Typical examples are the IBM PC and the Apple Macintosh. A laptop is a portable computer that has a flat LCD screen and uses batteries for mobile use. Small laptops are also called notebooks. The latest models can run as fast as similar desktop computers and have similar configurations. They are ideal for business executives who travel a lot. A tablet PC is a type of notebook computer that has an LCD screen on which you can write with a stylus or digital pen. Your handwriting is recognized and converted into editable text. You can also input text by using speech recognition or a small keyboard. You can fold and rotate the screen easily. Finally, a PDA is a lightweight, handheld computer. The letters stand for personal digital assistant. The term refers to a wide variety of handheld devices, including palmtops and pocket PCs. For input, you type using a small keyboard or use a stylus – a special pen to select items on the screen. PDAs can be used as mobile phones, personal organizers or media players. They also let you access the Internet via Wi-Fi networks, and some include a GPS navigation system. Decide whether these sentences are true or false. Correct the false ones. 1.
