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.
