Movie: 3. Laptop Computers.
A laptop computer is a small, light computer that you can easily carry about with you. It can be powered by battery or mains power. A laptop computer has a keyboard, and comes with specialised input devices, for example trackballs, touch pads or track points. They are needed because laptop computers are often operated in places where it is impracticable to use a mouse.
For output the laptop has an LCD or TFT screen and a set of small speakers.
‘Laptops’ are often as powerful as desktop computers and run the same range and type of software.
People use laptops for working when they are on the move, going to meetings or attending courses.
Many businesses are replacing desktop PCs with special plug-in workstations designed round laptop computers because of the flexibility they offer.
