A1: You can represent 3 bits of information in a single decimal digit: The most common scheme would be straight binary with wrapping where 0=8=000 and 1=9=001. But you could use any scheme there is nothing that says this is the only way to encode bits into decimal digits.

What is the length of the bits required to represent 234?

(1 bit = a single 0 or 1) in assemblies: nybbles (4 bits), bytes (8 bits), words (16 bits), or long words (32 bits). Place value works for binary just as it does for the decimal system. In ordinary decimal numbers 234 means 2×100 + 3×10 + 4×1 or 2×102 + 3×101 + 4×100.
