6 IGCSE Data representation Hex to binary and binary to hex

Learn how to effortlessly convert between hexadecimal and binary number systems in this IGCC Computer Science lecture. Discover the fundamental relationship where one hexadecimal digit directly corresponds to exactly four binary digits, known as a nibble. This video breaks down the simple swap method, requiring no arithmetic, to move between these systems. We demonstrate hex to binary conversion by replacing each hex digit with its four-bit equivalent and binary to hex conversion by grouping binary digits into fours and swapping them for their hex counterparts.
