Which of the following is considered the 'brain' of a computer?
RAM
Hard Drive
CPU
Motherboard
CPU
The Central Processing Unit (CPU) is referred to as the brain of the computer because it performs all the fundamental arithmetic, logical, control, and input/output operations specified by the instructions in a program. It processes data by executing cycles of fetching, decoding, and executing commands from the system's memory.

It processes data by executing cycles of fetching, decoding, and executing commands from the system's memory.
In the context of India's technological history, the development of the PARAM series of supercomputers by CDAC (Centre for Development of Advanced Computing) in 1991 marked India's entry into high-performance computing, which relies on sophisticated multi-core CPU architectures.
The CPU consists of the Arithmetic Logic Unit (ALU) and the Control Unit (CU).
Modern CPUs are often called microprocessors as they are fabricated on a single integrated circuit (IC) chip.
Clock speed, measured in Gigahertz (GHz), determines the number of instruction cycles a CPU can execute per second.
RAM (Random Access Memory) acts as the computer's short-term memory, holding data currently in use for quick access by the CPU.
The Hard Drive serves as non-volatile secondary storage, retaining data even when the computer is powered off.
The Motherboard functions as the main printed circuit board (PCB) that acts as a communication hub, allowing all components like the CPU, RAM, and storage to connect.
The concept of the stored-program computer, which CPU architecture follows, is based on the Von Neumann model.
C is correct тАФ The CPU (Central Processing Unit) acts as the primary component for processing data and executing software instructions.
When studying computer hardware, always link the CPU performance with 'Operating Systems' topics, as the OS is responsible for scheduling tasks and managing CPU resources effectively.
