- 1Binary CodeThe code in which all data and instructions in a computer as stored. This made of the digits 0 and 1
- 2communication DeviceA Device that allows a computer system to 'talk' to another system directly in binary code
- 3Computer misuse act (1990)The UK law that makes it illegal to hack into a person's computer and to disrupt deliberately someone else's computer
- 4Computer systemAll the parts that make a computer work, including the hardware, software and data. This may not be a traditional computer.
- 5Data Protection Act (1998)The UK law that tells organisations how they must protect the personal data of real people.
- 6Electronic white boardA computer system that uses a large white board as an input/output device in a classroom.
- 7Environmental issuesIssues concerned with whether something is good or bad for the environment.
- 8Ethical issuesIssues concerned with whether something is morally right or wrong in itself.
- 9Input deviceA device that allows data to be entered into a computer by transforming it into an electronic form.
- 10Output deviceA device that takes data which has been processed by the computer and translates it a human readable form.
- 11Storage deviceA device that stores data in a binary form for use later.
- 12Virtual Learning Environment (VLE)A computer system that helps teachers by allowing them to provide learning resources to pupils and monitor their progress.
- 13Boot programThe program that is used to start the computer. It is automatically loaded so that its instructions can be fetched when the computer is turned on, and it eventually loads the operating system.
- 14Central Processing Unit (CPU)The main component of the computer. It carries out all the processing by fetching and executing instructions.
- 15Clock speedThe speed at which the processor carries out instructions, measured in Megahertz (MHz) or Gigahertz (GHz).
- 16CoreEach single processor circuit capable of fetching and executing instructions.
- 17CPU cacheMemory buffer on the processor that stores instructions which have been fetched before and allows them to be fetched more quickly the next time.
- 18Fetch–Execute cycleThe process by which programs are run on a computer. The processor repeatedly fetches the instructions of the program from memory and executes them.
- 19Multi-core processorA processor with more than one core (processor circuit) which means it can fetch and execute more than one instruction at a time.
- 20AND gateA logic gate that has two inputs. If both inputs are ‘1’ it will output ‘1’, otherwise it will output ‘0’.
- 21Binary digitThe digits ‘0’ and ‘1’.
- 22Binary numberA number consisting only of binary digits.
- 23Denary numberA number that uses the denary digits from 1 to 10.
- 24Digital circuitAn electronic circuit based on binary numbers, where the presence or absence of electricity in any part of the circuit is represented by the digits ‘1’ and ‘0’.
- 25Logic gateA special circuit that allows a specific outut depending on the inputs. A processor is made up of millions of these circuits.
- 26NOT gateA logic gate that has one input. If the input is ‘0’, its output is ‘1’. If the input is ‘1’, its output is ‘0’.
- 27OR gateA logic gate that has two inputs. If either or both of the two inputs is ‘1’, its output is ‘1’.
