In this lesson, students explore different units of data.
Learning Objectives:
Define the terms bit, nibble, byte, megabyte, gigabyte, terabyte
Suggested time: 50 mins
Curriculum Mapping:
KS3:
Understand how data of various types (including text, sounds and pictures) can be represented and manipulated digitally, in the form of binary digits
COMPUTER SCIENCE EDUCATORS:
1a: Demonstrate knowledge of and proficiency in data representation and abstraction
Effectively use primitive data types
Demonstrate an understanding of static and dynamic data structures
Effectively use, manipulate and explain various external data stores: various types (text, images, sound, etc.), various locations (local, server, cloud), etc.
Effectively use modeling and simulation to solve real-world problems
CSTA K–12 CS Standards:
2-DA-07: Represent data using multiple encoding schemes.
3A-DA-09: Translate between different bit representations of real-world phenomena, such as characters, numbers, and images.
Ask students to investigate different units of data and to create a revision resource which explains the terms bit, nibble, byte, megabyte, gigabyte and terabyte.
