a symbol or word that instructs the computer to perform a specific calculation or action

a collection of data in a particular sequence

Mathematical operations in data structures

Computing

In this unit pupils will discover how data is represented and processed in sequences, such as lists and strings. They will cover a spectrum of operations on sequences of data, that range from accessing an individual element to manipulating the entire sequence though real world practical activites.
