Study Notes
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.
