Study Notes

Overview of Computer System Components and Software

A computer system consists of hardware and software working together to process data.
The central processing unit (CPU) is responsible for processing data and instructions.
The CPU consists of four main parts: Control Unit, Arithmetic Logic Unit, Cache memory, and Registers.
The Control Unit coordinates the activities of the CPU and is responsible for the FDE (Fetch, Decode, Execute) cycle.
The ALU performs logical and arithmetic calculations.
Cache memory is fast memory in the CPU that stores regularly used data.
Registers, such as the Program Counter and Accumulator, hold memory addresses and data.
The Von Neumann architecture is a computer architecture where the CPU runs programs stored in main memory (RAM).
The FDE cycle describes how the CPU carries out instructions, involving fetching, decoding, and executing.
RAM is the main memory where data and programs in use are stored.
ROM is non-volatile memory that stores essential data and instructions for booting up the computer system.
Factors affecting CPU performance include clock speed, cache size, number of processing cores, and RAM capacity.
