Type: Informational Material

Overview:

Data is stored differently depending on its type. Numbers are stored as integers or real numbers, text as string or characters. Lists of the same type of data can be stored in an array.

This webpage examines integer data, real or float data, characters, strings, boolean values, and arrays.

Content Standard(s):
Digital Literacy and Computer Science

Grade: 8
21) Differentiate types of data storage and apply most efficient structure.

Examples: Stack, array, queue, table, database.

Unpacked Content
Evidence Of Student Attainment:
Students will:
  • identify which data storage structure is used given a set of data and the intent on using that data.
Knowledge:
Students know:
  • different types of data storage and the appropriate use of those structures.
Skills:
Students are able to:
  • apply the most efficient data storage given a set of data.
Understanding:
Students understand that:
  • applying appropriate tools, in this case a data structure, to appropriate task increases efficiency.
