Programming Key Terms
Before you embark on your practical investigation you will need
to know the meaning of some key programming terms:
Algorithm – A series of steps designed to solve a mathematical
or other problem
Sequence – A list of instructions to be carried out in order,
one after the other.
Selection – The pathway through a program is selected by using a
condition to decide on what instructions to execute next i.e IF
Statements, or SELECT CASE Statements.
Iteration (repitition) – A group of instructions is executed
repeatedly until a condition is met.
