Computer architecture

Computer architecture - Quiz

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.
