In a computer, the smallest storage unit is byte, and the smallest recognizable unit is bit, 0 or 1. 1byte=8bit.
When it comes to high and low bits, at least 16 bit = 2 bytes should be stored.
For example, the numbers in the memory are:
0 1 1 1 1 100 10000000
0111100 This is the high eight, 10000000 This is the low eight.
16 stop loss is expressed as:
0x7c80
10 is expressed as:
3 1872
Octal is:
076200
The actual storage content is not necessarily an integer, but can be two asccii characters or a utf- 16 encoded character.
