What is the brain of the computer?
a) Central Processing Unit (CPU)
b) Random Access Memory (RAM)
c) Hard Disk Drive (HDD)
d) Power Supply Unit (PSU)
Answer:
a) Central Processing Unit (CPU)
Explanation:
The Central Processing Unit (CPU) is often referred to as the brain of the computer because it performs most of the processing inside a computer. It carries out instructions from programs by performing basic arithmetic, logical operations, control, and input/output operations.
The CPU interprets and executes commands from both hardware and software. It is critical to the overall functionality of the computer, determining how fast tasks are completed based on its processing power.
Modern CPUs are capable of handling multiple tasks simultaneously through multi-core processing, which enhances the computer’s efficiency and speed when running complex programs or multiple applications at once.
