What is Computer architecture and organization

Computer architecture and organization is the study of how computer hardware interacts with software to function as a complete system.

It involves understanding the components that make up a computer, including the CPU, memory, input/output devices, and storage units.

The term “architecture” refers to the design of these components and their interconnectivity, while “organization” refers to how they are arranged and managed within a system.

One key aspect of computer architecture is instruction set design. This involves creating a set of instructions that the CPU can understand and execute.

Different CPUs may have different instruction sets, which can affect their performance and compatibility with software applications.

Other important considerations in computer architecture include memory hierarchy, where data is stored at different levels of speed and capacity depending on its usage frequency; bus systems for transmitting data between components; and interrupt handling for managing unexpected events or prioritizing tasks.
