In Assembly, Do Instructions Refine Data Types?

Question

I am starting to program in assembly language (x86).

Is the following true for him?

In assembly data types, such as BYTE, WORD, DWORD, respectively 8 bits, 16 bits and 32 bits, not only INTEGERS. They have no meaning in themselves, they are just bit patterns. The instructions that use them give them meaning.

Answer 1

The "assembly" code contains many special instructions that work with operands of various sizes (for x86, 1 or more bytes), which contain values ​​that require individual instructions of a certain type.
