257
If the contents of this byte (01000001) were written in hexadecimal the value would be:
41
If the top byte represents an integer and the bottom byte is used on the top byte with a bitwise logical AND. 01000001 11100111
65
If the contents of this byte (01100111) were written in hexadecimal the value would be:
67
These two bytes added as integers gives the integer: 00100011 00100010
69
How many bits are in a byte:
8
If the top byte is an 8 bit integer then a bit wise OR with the bottom byte gives: 01100011 01000010
99
