A scientific instrument outputs its status logs as a sequence of characters encoded in standard 7-bit ASCII. Determine the total number of bits required to represent a status message that is exactly 12 characters long.
Practise Edexcel GCSE Computer Science Data representation with exam-style questions for GCSE Computer Science. 50 questions covering Encoding characters with 7-bit ASCII, Representing bitmap images in binary, Representing analogue sound in binary, and Limitations of binary representation, matched to the Edexcel GCSE Computer Science (1CP2) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
