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
