👉 Processor computing, or simply computing by processors, is the process of performing calculations and manipulating data using multiple processing units, typically within a central processing unit (CPU) or more complex architectures like multi-core processors, GPUs, or FPGAs. At its core, a processor executes instructions from software by fetching them from memory, decoding the instructions to determine the operation required, and then executing that operation using arithmetic logic units (ALUs), registers, and other components. Modern processors can handle multiple tasks simultaneously through techniques like pipelining and parallel processing, allowing them to perform complex computations at high speeds. This capability is fundamental to the functioning of computers, enabling them to run applications ranging from simple tasks like word processing to highly demanding operations such as artificial intelligence, scientific simulations, and data analysis.
