Question: Which of the following is also known as brain of computer

Answer:

The "Central Processing Unit" (CPU) is also known as the brain of the computer.

The CPU is a crucial component of a computer system responsible for executing instructions and performing calculations. It acts as the primary processing unit that carries out the instructions of a computer program. The CPU interprets and executes instructions fetched from memory, performs arithmetic and logical operations, controls the flow of data within the computer, and coordinates the activities of other hardware components.

The CPU consists of two essential components: the control unit and the arithmetic logic unit (ALU). The control unit fetches instructions from memory, decodes them, and directs the operations of the other components. The ALU performs arithmetic operations (such as addition, subtraction, multiplication, and division) and logical operations (such as comparisons and boolean operations).

The CPU's role as the brain of the computer is analogous to how the human brain processes information, makes decisions, and coordinates the activities of the body. It is responsible for the computer's overall functionality and plays a critical role in executing software programs and performing tasks.
