This is the first module we are filming. The finished video, short notes and practice questions will go on this page. A test cut is on the home page for now.
Scope This module is logical shifts only: zeros fill the gaps and bits fall off the end. Edexcel also asks for arithmetic shifts and two’s complement. They have their own modules: 2.6 Two’s complement and 2.7 Arithmetic binary shifts.
