What is the CPU?

 The CPU (Central Processing Unit) is the brain of the computer. It processes instructions and handles all basic operations needed for the system to function, including running programs and managing hardware.

The CPU follows a cycle: it fetches instructions from memory, decodes them, executes them, and stores the result if needed. This happens millions of times per second.

Key parts of a CPU include:

• ALU (Arithmetic Logic Unit): handles calculations and logic.

• Control Unit: directs data flow.

• Registers: store temporary data.

• Cache memory: stores frequently used data for faster access.

Important CPU features:

• Clock speed (GHz): how fast the CPU works.

• Cores: each core can handle tasks; more cores = better multitasking.

• Threads: virtual cores that improve efficiency.

• Architecture: the CPU's design (e.g., x86, ARM).

• TDP: how much heat the CPU produces.

CPUs need cooling (air or liquid) to prevent overheating, which can slow performance or damage the hardware.

Main CPU brands:

• Intel: Core i3, i5, i7, i9

• AMD: Ryzen, Threadripper

• Apple: M1, M2, M3 (Apple Silicon, ARM-based)
