  • 1. Computer architecture refers to the design and organization of the components of a computer system. This includes the structure of the central processing unit (CPU), memory, input/output devices, and other hardware components. It also encompasses the instruction set architecture, which defines the operations that a CPU can perform and the formats in which they are encoded. Computer architecture is essential for understanding how computers work and how to optimize their performance and efficiency.

    What does CPU stand for?

C) Central Processing Unit
D) Control Processing Unit
  • 2. Which component is responsible for storing temporary data that can be accessed quickly by the CPU?
A) Cache memory
B) RAM
C) Registers
D) Hard drive
  • 3. What is the purpose of the ALU in a CPU?
A) Maintain system clock
B) Store program instructions
C) Perform arithmetic and logical operations
