12. OCR GCSE (J277) 1.2 Units of data storage
OCR J277 Specification Reference - Section 1.2 In this video we explain why computers use binary to store data. The difference between a bit, nibble, byte, kilobyte, megabyte, gigabyte, terabyte and petabyte is explained. These are known as measurements of capacity, or how much data can be stored either in memory or on secondary storage devices. Don't forget, whenever the blue note icon appears in the corner of the screen, that is your cue to take notes about the content being shown on the current slide. 00:00 Units of data storage 00:06 Intro 00:11 About units of data capacity - Part 1 03:07 Units 05:12 Converting between units 05:51 About units of data capacity - Part 2 07:12 Going beyond the GCSE specification 07:26 Data capacity vs transfer speeds 08:09 Outro Comments are disabled on our videos because we want to ensure they are always appropriate to use in the classroom.
