​Data Structures

The primary purpose of a computer system is to process data. The data can be of any type. If a computer program needs to process one piece of data, then that data can be stored in a variable and the resultant data can be stored in another variable. In this case, a couple of variables are sufficient to write a program. But real-life programs need to handle tens of thousands of pieces of data. To handle large amounts of data, it is impossible to store each piece data in a separate variable. Therefore, data is grouped together or, more precisely, structured in a specific format. The collection of data structured together is called a data structure. In this article, types of data structures and implementation of data structures in computer programs are discussed.

This GCSE Computer Science module introduces ​​data ​structures to your students, explaining:

  • ​Different types of ​data structure
  • ​Arrays
  • Declaring arrays
  • Using arrays in Python
