Instructions and memory address are represented by
A. Character code
B. Binary codes
C. Binary word
D. Partiy bit
E. None of these
Answer: Option B
Solution (By Examveda Team)
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.
The correct answer is b) binary word.
Explanation:
Instructions and memory addresses in computers are typically represented as binary words, which are sequences of binary digits (0s and 1s). A "binary word" is a unit of data used by a computer, where the length of the word (e.g., 16 bits, 32 bits, 64 bits) depends on the architecture of the system. These binary words are used to represent instructions (machine code) and memory addresses in a form that can be processed by the CPU.
Why the other options are less suitable:
a) Character code: Character codes (such as ASCII or Unicode) are used to represent text characters, not instructions or memory addresses.
c) Binary code: While this is a broad term that could technically apply to both instructions and memory addresses (since they are represented in binary), the more precise term used in computer architecture is binary word when discussing how instructions and addresses are represented.
d) Parity bit: A parity bit is used for error detection and is a single bit added to data to make the number of 1s either even or odd. It is not used to represent instructions or memory addresses.
Thus, the correct term is binary word, which represents instructions and memory addresses in a computer system.
B) Binary Codes
