The color (core) are smaller processing units. Interconnected within the CPU, they share the workload more efficiently. It is common to see terms such as dual-core (two cores), quad-core (four cores), octa-core (eight cores), among others, even for mobile devices. In a simplified way, the processor receives an instruction from an app or the operating system, performs a calculation and issues a response. The process is divided into three stages, which are: The processor has several specialized units inside it, in addition to registers (an extremely fast and expensive type of memory) and other levels of memory of its own, as we will show below. The arrangement of these transistors in larger units allows complex operations to be performed in a fraction of a second. Therefore, the processor is the unit responsible for translating each command received and generating a response, whether to open an application, play a video on YouTube or run a game of Fortnite (something done with the aid of the GPU, the video card). The modern processors for PCs are built from billions of transistors, small components that individually perform operations from electrical signals, which are converted to the digital world in binary form “0” and “1”. Everything is manufactured on a nanoscale scale, making it impossible to observe each of the physical parts with the naked eye. The processor is one of the main parts of an intelligent electronic device, be it a PC, smartphone or even a smartwatch. It is responsible for processing practically all the commands and operations performed on the computer, acting from the control of the RAM memory to the opening and execution of a program, communicating with the other parts of the machine through the motherboard and its various buses.įor its function, the processor is often considered as the brain of the computer, also acting in the organization of the entry and the exit of the data, in the recording of the information in the memory and in the storage devices.Ĭurrently, the two main computer processor manufacturers are Intel and AMD. Both produce CPUs for virtually all price and performance segments, as we will see later. What is a processor and how does it work?
