     • In an LCD TV projector, a very bright light shines through a small LCD screen into a lens, which throws a hugely magnified image of the screen onto the wall.

     • When a fluctuating electric current flows through the coil (orange), it becomes a temporary electromagnet, attracted and repelled by the permanent magnet (blue/red).
   • Camera
     • When you press the button to take a photograph with a digital camera, an aperture opens at the front of the camera and light streams in through the lens. So far, it's just the same as a film camera. From this point on, however, everything is different. There is no film in a digital camera.

3. Storage

   • Memory stick

   • DVD
     • t's amazing when you think about it: you can store a movie several hours long on a shiny piece of plastic no bigger than your hand! Although compact discs (CDs) have been around for more than 30 years, they are still one of the most popular ways of storing music and computer data.
   • CD
     • A compact disc is a thin, circular disc of metal and plastic about 12cm (just over 4½ inches) in diameter. It's actually made of three layers. Most of a CD is made from a tough, brittle plastic called polycarbonate. Sandwiched in the middle there is a thin layer of aluminum. Finally, on top of the aluminum, is a protective layer of lacquer.
   • SD card
   • Hard Drive
     • is a data storage device used for storing and retrieving digital information using one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material.
