- 1DataA collection of facts without context, such as 7 11 14 is data you don’t know what it is but 7/11/14 is information
- 2Computational thinkingThinking logically about problems in terms of the problems
- 3ComputeTo compute means to carry out mathematical calculations.
- 4Input deviceAn input device enables the user to input data in to a computer.
- 5MemoryThis is where a computer keeps data that has been input, as well as software applications and the result of any processing it has carried out for the short term. This memory is lost when the computer is off.
- 6Storage deviceComputer stores files that have been created.
- 7ProcessorProcesses data according to the instructions it has been given. It provides the user with information.
- 8Output deviceEnables user to receive information from a computer.
- 9DecimalUsed for counting and computation. Uses ten digits: 0,1,2,3,4,5,6,7,8 and 9. Also called base 10.
- 10BinaryNumber that uses two digits. 0+1. All electronic computation is carried out using binary system. Also called base 10.
- 11BitBit is used to describe one binary digit and is derived from BInary digiT
- 12ByteA string of bits, usually 8 for example 10010101 is called a byte.
- 13DecomposeBreak a problem down in to a series of simpler problems.
- 14AlgorithmA set of step by step instructions.
- 15InformationInformation is data that has been processed by adding a meaning through interpretation and by asking questions and by asking questions.
- 16ModelSomething created to intimate a real life situation
- 17Pattern identificationLooking for identifiable patterns in raw data using data analysis
- 18Hypothesis testingA proposed explanation for something. You can test it to see if its correct, using observation and investigation
- 19AbstractionWorking with ideas or solving a problem by identifying common patterns in real situations, concentrating on general ideas and not on the detail of the problem itself. For example drawing a cat - we know they have a tail, eyes and fur and also they meow and like fish. But we don't NEED to know they meow or like fish to draw them. So we have a clearer idea
- 20GeneralisationTaking concepts used in the solution of a particular problem and using them to solve other problems that have similar features.
- 21Geometrical shapesShapes that are defined by a set of mathematical rules
- 22Iterationusing repetition of a process to create a more efficient solution
- 23Graphical programmingProgram language that allows users to create programs using graphics rather than text
- 24Text-based programmingA programming language that requires the user to write code in the form of a sequence of text based instructions into the computer to create the program
- 25Dry runTo run through a program on paper to see how it works. A dry run records the state of each variable when each line of the program is executed, so it has one line for each line of code in the program
- 26ExecuteTo carry out something, usually a set of instructions
- 27SequenceA sequence of instructions is a set of instructions that must be followed one after the other in a specific order
- 28ProcedureA procedure is a sequence f program instructions that have been abstracted and can be used over and over again. It can accept input from other parts of the program.
- 29FunctionLike a procedure, a function is a sequence of program instructions that have been abstracted and can be used over and over again. Again, like a procedure, it can accept input from other parts of the program, but it can also return information back to other parts of the program.
