Computer System Components and Functions

A computer system consists of hardware and software working together to process data.
The CPU (central processing unit) is responsible for processing data and instructions.
The CPU consists of the control unit, ALU, cache memory, and registers.
The control unit coordinates the activities of the CPU and is responsible for the FDE cycle.
The ALU performs logical and arithmetic calculations.
Cache memory is super fast memory in the CPU that stores regularly used data.
Registers such as MAR, MDR, ACC, and PC hold memory addresses, data, and instructions.
The Von Neumann architecture is characterized by the CPU running programs stored in main memory and using one memory for both data and instructions.
The FDE cycle involves fetching, decoding, and executing instructions.
RAM is the main memory where data and programs in use are stored.
Virtual memory is used when RAM is full and is slower than RAM.
Secondary storage, such as solid state, magnetic, and optical storage, is used for storing data not in use.
