[#170] Instructions and memory address are represented by
Correct Answer

(B) Binary codes
(F) Binary codes

Explanation

Solution: Computers work with binary code . This means they use only two digits: 0 and 1. Everything inside a computer, from the simplest instruction to the location of data (memory address), is represented using combinations of these 0s and 1s. Option A is incorrect because character codes (like ASCII) represent letters, numbers, and symbols, not the fundamental instructions or memory locations. Option B is correct because binary codes are sequences of 0s and 1s used to represent instructions and memory addresses. Option C is also related to binary representation, but “binary word” is a more general term; “binary code” is more specific to the representation of data and instructions. Option D is incorrect; parity bits are used for error detection, not for representing instructions or addresses. Option E is incorrect because binary codes are the correct answer.
