- 1RAM (Random Access Memory)Main memory of computer that stores data,applications and the operating system while in use.When the power is turned off RAM loses it's data.
- 2Cache MemorySpecial high speed memory used by a computer.
- 3Solid stateTechnology based on electronics with no moving parts, for example transistors and capicatators as used in memory chips.
- 4Flash memorySolid-state memory used as low cost secondary storage in portable devices and as removable memory.
- 5Volatile and Non-volatile memoryData lost when there is no power
Data rentained even when power turned off. - 6Embedded systemA computer system that forms part of an electronic device.
- 7TCP/IPTransmisson control protocol/internet protocol - a set of standards that control how data is sent across networks including the internet.
- 8Binary and DenaryA system of number using only two digits '0' and '1', unlike the decimal (denary) system in everyday use that that uses ten.
- 9CPUCentral processing unit of the computer containing the control unit, ALU and cache memory.
- 10ALUThe ALU performs all the arithmetic and logical operations within the CPU.
- 11Secondary storageNon-volatile storage used to store programs and files that need to be kept even when the power is not on.
- 12Fetch-execute cycleThis is the process of fetching the instruction from memory, decoding them and then executing them so that the CPU performs continuously.
- 13ROMRead only memory, a store for data in a computer that cannot be overwritten. Data in ROM is always avaliable and is not lost when the computer is turned off.
- 14Virtual memoryA section of hard disk used as if it were RAM to supplement the amount of main memory avaliable to the computer.Used when there is not enough main memory to run the programs required.
- 15Input devicesA hardware device used to input data into a computer system for processing. e.g.
Graphics tablets, Trackballs, Bar code reader, Digital camera, Game pad, Joystick, Keyboard, Microphone, Mouse or pointing device, Scanner, Webcam, Touch pads, Pen Input, Microphone, Electronic Whiteboard. - 16Output devicesA hardware device used to output data from a computer system. e.g.
3D Printer, Flat panel, GPS, Headphones, Monitor, Plotter, Dot matrix printer, Inkjet printer, Laser printer, Projector, Sound card, Speakers, Speech-generating device, TV,Video card.
