cpu

The Central Processing Unit (CPU) is often called the brain of the computer—and for good reason. It’s the main component responsible for carrying out instructions and running programs. Every time you open an app, browse the internet, or type a document, the CPU is hard at work behind the scenes, processing data and making things happen. A CPU is made up of two main parts: the Arithmetic Logic Unit (ALU) and the Control Unit (CU). The ALU handles all the mathematical and logical operations, like adding numbers or comparing data. The Control Unit, on the other hand, directs the flow of information, telling other parts of the computer what to do and when. Modern CPUs can have multiple cores—which means they can do several tasks at once. For example, a quad-core CPU has four processing units, allowing it to handle multitasking much more efficiently. This is why more cores usually mean better performance, especially when running heavy software or multiple programs. The speed of a CPU is measured in gigahertz (GHz). A higher number means the processor can execute more instructions per second, but performance also depends on architecture and how efficiently it handles tasks—not just raw speed. In short, the CPU is the powerhouse that drives your computer’s performance. Whether you're gaming, working, or just browsing, the CPU is constantly calculating, managing, and keeping things running smoothly. Without it, a computer simply wouldn't function.
