Explanation

A graphics card (GPU) handles the rendering of images, videos, and animations on the computer screen.

It is essential for tasks like gaming, video editing, and graphic design.

Explanation

Clock speed measures how fast a computer's processor can execute instructions.

It is expressed in Gigahertz (GHz).

1 GHz equals 1 billion cycles per second, indicating the processor’s speed.

Explanation

The Control Unit (CU) directs the operation of the Arithmetic Logic Unit (ALU).

It tells the ALU what operation to perform based on the instructions from the program.

Explanation

The CPU (Central Processing Unit) includes:

1. ALU (Arithmetic Logic Unit)
2. CU (Control Unit)
3. Registers (temporary storage inside CPU)

Primary Storage (like RAM) is not part of the CPU; it is part of the main memory.

Explanation
