This loop is controlled by a condition at the start of the loop

(a)  

This logic gate takes one input and has one output which is always opposite to the input

(a)  

This logic gate takes two inputs and gives one output. If both inputs are 1 then the output is 1, otherwise it is 0

(a)  

This logic gate takes two inputs and gives one output. If either input is 1 then the output is 1, otherwise it is 0

This programming feature is a data structure which allows you to store a collection of data values. It can be a single column list (one dimensional), double column list (two dimensional) or more.

(a)  

Used to describe something which changes value smoothly, it is the opposite of digital which changes something in steps

(a)  

Used to describe something which changes value in steps, it is the opposite of analogue which changes something smoothly

(a)  

This means to make a copy of the data held on the system in case the original data is lost or damaged

(a)  

This term is the measure of capacity of a communications channel.

It measures the amount of data which can be uploaded or downloaded in a specific measure of time

(a)  

This is the smallest amount of information that a computer can store. It can be set to 0 (false) or 1 (true), this is called binary

(a)  

This is made up of 8 bits

(a)  

This piece of software translates a computer program written in a high level language into machine code in one go to create an .exe file

(a)  

This piece of software translates a computer program written in a high level language into machine code one line at a time

(a)  

This is a form of very fast memory used to avoid having to continually fetch data from RAM. A CPU may have one or more levels of this memory to hold frequently-used data and instructions.

(a)  

This describes how the speed of a CPU is measured and is recorded in Hertz, eg a PC might have a 3.8GHz processor

(a)  

The process of reducing the size of a data file so that it takes up less space on a storage drive or can be sent quicker via the internet

(a)  

A type of compression which removes data meaning that the original file can never be replicated

(a)  

A type of compression which retains all of the original data meaning that the original file can be fully recreated

(a)  

This is the part of the CPU which controls the flow of information through the processor

(a)  

This is the process of reorganising the data on a hard drive to put parts of files back together and collect all the free space together

(a)  

The process of scrambling data to prevent third parties from being able to access it

(a)  

This is the name for all of the characters that a computer system can represent

(a)  

This is the data stored in an image file to help the computer recreate an image from the binary data. It will contain details of file format, height, width, colour depth and resolution

(a)  

This term describes the number of bits available to store colour data for each pixel in an image

(a)

This sorting algorithm is used to put an unordered list in order by focussing on just two items at a time

(a)  

This type of sorting algorithm splits a list into indiviual items before combining them into increasingly larger lists

(a)  

This type of sorting algorithm takes the first item of a list as a starting point and creates a new list. It then takes each item in turn and puts it in the correct place in the new list
