What is Qword PTR?

qword ptr is a hint for the assembler to create a move op-code (machine code) using a 64bit constant address. The value that is provided is a 32bit value (8 hex-digits => 8 times a hex-digit/letter => 8 * 4bits => 32bit).

What is a word in assembly?

How many bits is a character?

eight bits

What happens to values above 255 in binary?

There is nothing specific for values above 255. There is just a particular approach to convert a given decimal to binary. The thing to know is that you need to sequentially divide the given decimal (base 10) value by 2 and write down the floor(factor). For example over here 255 /2 =127.5 and now the floor(127.5) =127.
