An embedded systems engineer is designing a low-power digital display and needs to choose between a 4-bit colour depth and a 12-bit colour depth to represent bitmap images.
Compare the binary representation, colour capabilities, and storage requirements of these two options.
40 exam-style questions on Edexcel GCSE Computer Science Data representation, covering Encoding characters with 7-bit ASCII, Representing bitmap images in binary, Representing analogue sound in binary, and Limitations of binary representation. Each one has a worked solution and a mark scheme showing where the marks go.
