1.2.3 units & data capacity


Topic Intentions

Lesson Objectives


  1. To know what the terms bit, nibble, byte, kilobyte, megabyte, gigabyte, terabyte, petabyte mean
  2. Know the Data capacity and calculation of data capacity requirements (sound, text, audio)
  3. What metadata isd calculation of data capacity requirements
  • Know what the various units of measurement are.
  • Be able to put them in order of size.
  • Calculate the various file sizes of image, audio and text files.

Lesson 1 Units Recap


Learning Intention: This lesson is about Units of Measurement.  You will learn recap the main measurements and units. 

Starter:
Look at the measurement of memory displayed on the board, place them into order of size, check with another student and correct them.

​​Plenary:​​
Working as a team, play the 'Wall of Measurement" game and place the values in order and under the correct headings.
​​
Impact:
​Play a Kahoot worksheet feeback

Lesson 2 Data Capacity


Learning Intention: Calculate required storage capacity for a given set of files (sound, images and text files)

Starter: List 5 facts that you remember from last lesson

Implementation: Learn the formula to calculate the file sizes, 
  • sound file size = sample rate x duration (s) x bit depth
  • image file size = colour depth x image height (px) x image width (px)
  • text file size = bits per character x number of characters
