- The software scans text/handwriting, interprets them, then generates a text file | Optical Character Recognition
- Reads product packaging, generates the product number so the rest of the details can be located in a database. | Barcode scanner
- Used on many compact portable devices where having a physical keyboard or mouse would be impractical due to size. | Touch screen
- A device to allow the user to give positional data to a computer using hand and wrist movement while keeping the user's arm steady | Trackerball
- A device to allow the user to give positional data to a computer using hand and wrist movement. Movement is detected using a reflected light source underneath the device. | Mouse
- A mechanical device used for physical data entry into computers by the user. Some users can accomplish data entry speeds of 80-90 words per minute. | Keyboard
Also offered: Head Wand; Retina Scanner; Laser Printer; Digital Camera; Finger Print Scanner

Q: Match the printer to the description:
- Can use continuous stationery or multi-part stationery. Paper is fed through the printer using the holes at the side. The holes are then torn off to give a printed page. | Dot-matrix Printer
- An early form of computer printer, very noisy because the print head has to strike the paper through an ink ribbon to print text on a page. | Dot-matrix Printer
- Modern printer capable of printing 10 - 100 pages per minute at a cost of about 1p per page for black & white. | Laser Printer
- The toner ink is supplied in the form of a loose dry powder that is sealed or fused onto the page during printing by heated rollers. | Laser Printer
- It works by spraying ink onto the page so if you have big shaded areas on a page the page will come out a bit damp and wrinkled! For normal text they produce good quality printing at a low cost. | Inkjet Printer
- The ink is never sealed on the page so if the printed page gets wet the ink will smudge. Quite slow so they are not suitable for a large office or classroom. | Inkjet Printer
- An impact printer that creates raised dots on the paper to represent each letter | Braille Printer
- Designed specifically to allow visually impaired people to read. | Braille Printer
Also offered: 3D Printer; Vinyl Cutting Machine; Litographic Printer
