WebJun 4, 2013 · Bit-shifting is an N-bit operation. Masking is also an N-bit operation. Depends on how you represent it internally, it's relatively easy to jump to the correct byte, but high-level languages (if you're using one) usually don't allow you to directly access a specific bit, you'll need some operation (e.g. bit-shift (of that byte only)) to get ...
