Unit 1 (1.1 part 1)

1. A pointing device which has a ball or laser light underneath to detect movement so that the user can control the position of the cursor by moving it; it usually has two buttons with different functions and a scroll button or wheel (4, 2, 1, 5)
5. Pointer is controlled by gripping the stick and buttons make selections, another button on the top is often used for gaming purposes; they are used for simulators (4, 2, 1, 8)
6. The general term for the physical components that make up a computer system e.g. keyboard monitor, processor, base unit etc. – if you can touch it or hold it, it is hardware (4, 2, 8)
7. A general purpose computer which is made up of separate monitor, keyboard and mouse and processing unit (base) (4, 2, 1, 2)

4. A basic program that governs the video card’s operations and provides the instructions that allow the computer and software to interface with the card (4, 2, 5, 4)
8. Hardware devices that allow data to be inputted into a computer, examples include keyboards and barcode readers (4, 3, 5, 7)
9. Device that inputs data to a computer where the data is a measurement of some physical quantity which is always changing; these physical qualities are analogue in nature and will need converting into digital using analogue to digital converter (4, 3, 7)
10. A computer where the monitor, keyboard, pointing device and processor are all together in one unit; they are the most common type of computer in the home (4, 2, 1, 6)
