Computer CPU (Central Processing Unit) is the main processor and the “brain” of every computer system. Responsible for executing instructions, handling data, and powering overall system performance, CPUs are one of the most valuable and critical hardware components in desktops, laptops, and servers. Modern processors are built using advanced semiconductor technology and often contain precious metals such as gold, silver, and palladium in their connectors and circuits. This makes computer CPUs important not only for computing power but also for recycling and recovery of valuable materials.
