A. character codes

B. binary codes

C. binary word

D. parity bit

### Check Answer

The correct answer is

Instructions and memory addresses are represented by binary codes. Binary code is a digital code that represents information using only two digits: 0 and 1.

Option A (“character codes”) is incorrect because character codes represent characters, such as letters, numbers, and symbols, using binary codes.

Option C (“binary word”) is incorrect because a binary word is a fixed number of bits that are processed as a unit by a computer.

Option D (“parity bit”) is incorrect because a parity bit is a binary digit that is added to data to check for errors in transmission.

Therefore, the correct answer is B) binary codes.
