Bit size 8-bit versus 16-bit
Increased computer speed has led some software to make use of 16-bit but not all software!

Think of bit size as the size of rucksack: a 8 kilo rucksack can be carried up a hill by most people but a 16 kilo will prove impossible for some. Does the size of your rucksack make you a better person?! Stick to 8-bit please.
