CPU

A CPU (Central Processing Unit) is the primary component of a computer that executes instructions from programs by performing basic arithmetic, logic, control, and input/output operations. It acts as the brain of the computer, processing data and managing system resources to run software applications and operating systems.

Also known as: Central Processing Unit, Processor, Microprocessor, Chip, CPU Unit

Why learn CPU?

Developers should understand CPU concepts to optimize code performance, manage system resources efficiently, and design scalable applications. This knowledge is crucial for tasks like parallel programming, algorithm optimization, and troubleshooting performance bottlenecks in high-load systems or embedded devices.
