The CPU is the brain of the computer and handles. The CPU produces heat and are covered by a heat sink to keep cool and regulate the temperature. Each CPU sockets fit certain types of CPU.
Arithmetic Logic Unit
the Arithmetic logic unit which handles the maths ,calculations , logic and decision-making.
The Control Unit forwards controls to the rest of the computer
Memory Management Unit
the memory management unit translates the logical address to the RAM
the instruction register hold the instruction which is currently being executed by the cpu
The program counter dosen’t count programs. Instead it holds the addess of the instruction which is being processed by the cpu. The program counter then directs the next instruction.
Fetch,Execute , decode
Fetch execute and decode sis the cycle the cpu goes through when executing instructions and performing tasks .
First the information for the task is fetched from the RAM on the motherboard. Then the instruction is fetched by the program counter. First the instruction need to be decrypted. The CPU decodes the instruction . The process is executed then and the instruction is stored in the registry on the cpu
CPU employ clock signals which changes depending on how much the CPU is being used.The faster the clock speed the more operations and instructions can take place at once.
The CPU includes integrated graphics. Integrated graphics are okay for general 3d rendering, video editing. Integrated graphics shares a small percentage of ram in the computer. However Integrated graphics have got better over time. Below is a link to PC Gamer’s test using integrated graphics using intel graphics 520.
