Which of the following statements are true about a CPU? i. The full form of CPU is Central Processing Unit. ii. It acts as the primary component that performs arithmetic and logic operations. iii. The CPU exists as a set of instructions stored on a hard drive. iv. Modern CPUs are integrated circuits known as microprocessors.
i, ii and iii
i, ii and iv
ii, iii and iv
All are true
i, ii and iv
The Central Processing Unit (CPU) is the primary logic circuitry of a computer that interprets and executes instructions from software. Statement (iii) is incorrect because the CPU is hardware (an integrated circuit), not software instructions stored on a hard drive.
ISO/IEC 2382:2015
The Central Processing Unit (CPU) is the primary logic circuitry of a computer that interprets and executes instructions from software. Statement (iii) is incorrect because the CPU is hardware (an integrated circuit), not software instructions stored on a hard drive.

The CPU follows the Fetch-Decode-Execute cycle. It fetches instructions from memory, decodes them into control signals, and executes them using the Arithmetic Logic Unit (ALU) and Control Unit (CU) to perform operations on binary data.
CPU serves as the brain of the computer, executing basic arithmetic, logic, control, and I/O operations.
A microprocessor is a CPU fabricated on a single integrated circuit.
Modern CPUs utilize multiple cores to increase parallel processing capabilities.
Data resides in registers during processing, which are faster than system RAM.
High computational speed for complex calculations
Versatility in handling diverse software workloads
Generates significant thermal energy requiring cooling solutions
Subject to physical limitations like clock speed ceilings due to power density
Personal computers and servers
Embedded systems and IoT devices
Statement (iii) describes software or programs, whereas the CPU is the physical hardware executing them.
Microprocessors evolved from discrete components to LSI (Large Scale Integration) and VLSI (Very Large Scale Integration).
B is correct тАФ Statements (i), (ii), and (iv) accurately define the role and nature of a CPU, while (iii) incorrectly confuses hardware with software data.
In exams, remember that a CPU is the 'processor' (hardware), while the 'program' (software) consists of instructions stored on secondary storage.
