Machine Language:
• The number of bits that form the “word” of a microprocessor is fixed for that particular processor. – These bits define a maximum number of combinations.
• For example an 8-bit microprocessor can have at most 28 = 256 different combinations.
• However, in most microprocessors, not all of these combinations are used. – Certain patterns are chosen and assigned specific meanings. – Each of these patterns forms an instruction for the microprocessor. – The complete set of patterns makes up the microprocessor’s machine language.
