Question | Answer |
abstraction | the process of operating and filtering out ideas and specific details that are not needed in order to con concentrate on those that are needed. |
algorithm | a sequence of logical instruction for carrying out a task in computing. algorithms are needed to design computer programs. |
binary search | a faster method of searching, in which the data being searched is halved with every step |
bubble sort | a sorting algorithms that repeatedly passes though a list to be sound, comparing and swapping items that are in the wrong order |
bucket sort | a sorting algorithm m that separate data into different collection called buckets which are filled with data and then sorted |
computational thinking | a problem solving method using computer science Technics were possible solutions are developed and presented in away that is understandable by humans and computers. |
condition | in computing, this is a statement or sum that is ever true or false. a computation depends on whether a condition equates to true or false. |
counter | device which stores (and / or displays) the number of times a particular event or process has occurred. |
criteria | a set of rules or condition that must be met. often using searches |
data | unit of information. in computing there can be different data types including integers, characters, and Boolean. data is often acted on by instructions. |
data type | the format in which a variable or constant holds data such as integer or string. |
database | a system designed to store data in an organised way making it easier to search for the information that you need. |
decomposition | the breaking down of the system in to smaller parts that easier to understand, program and maintain. |
design criteria | principles and standard that designers should meat in designing a system. |
flowchart | a digraph that shows a processed a box that representing a steps, decision, inputs and outputs. |
input | entries or changes which are inserted into a system and which activate/ modify and process. |
instruction | a single action that can be performed by a computer processor. |
iteration | in computing programming, this is a single pass through a set of instruction. |
keyword | an important word that will help return accurate search result. |
logical reasoning | the application of rules to problem solving. |
loop | a method used in programming to repeat a set instructions. |
notation | a system of written symbols or graphics used to represent something in order to aid communication and understanding. |
output | either an exit or changes which exit a system and which activate or modify a process. |
pattern recognition | finding similarities and patterns in order to solve complex problems more efficiently |
program | sequences of instructions for a computer. |
programming | the process of writing computer software. |
programming language | A language used by a programmer to write a piece of software. there are many programming languages. |
pseudo code | a method of write a set of instructions for a computer program using plain English. this is a good way of planning a program before coding. |
selection | a dissension with in a computing program when the program deiced to move on based on the results of an event. |
sequences | in computer programming, this is a set of action that follow on one from another. |
serial search | a simple of search in which the search moves from one item to a next in a sequence until either a match or end of the data which no match has found. |
sorted | when things are put in to order e.g. from largest to smallest. |
specification | a statement that tells the design exactly what the product has to to and the design requirements are. |
sytax | rules governing how to write statement in a programming language. |
variable | in computer program this is a memory location where values are stored |
