AQA A Level Computer Science - Paper 1 –[2024] Strongly Typed -ANS-What type of language is Pascal? This type of language helps to reduce run time errors by forcing declaration of variables & data types, & captialisation. Constant -ANS-An item of data whose value DOESN'T change Variable -ANS-An item of data whose value COULD change, while being run Algorithm -ANS-A sequence of steps that can be followed to complete a task in a finite number of steps, always terminates. Element -ANS-A single value within an array (list) Record -ANS-One line of a text file Selection -ANS-Principle of choosing what action to take, based on certain criteria (conditions) - IF & CASE STATEMENTS Nesting -ANS-Placing one set of instructions inside another set of instructions Iteration -ANS-Principle of repeating processes - FOR, WHILE, REPEAT UNTIL Definite iteration -ANS-Process that repeats a set number of times - FOR LOOP Indefinite Iteration -ANS-Process that repeats until a certain criteria is met - WHILE Sequence -ANS-Principle of putting the correct instructions in the right order within a
