Data Representation KS3

Data Representation KS3 is a five-mission Year 8 computing activity book mapped to the DfE National Curriculum for understanding how data is represented in binary. Pupils learn that computers store everything as binary (base 2), define a bit and a byte and order the units KB, MB, GB and TB, convert between binary and denary using 4-bit and 8-bit place values, and discover how text is stored with character codes such as ASCII (capital A = 65), how images are built from pixels, and how sound is captured by sampling. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
