The CPU communicates with peripherals via a bus. This bus is a set of electrical pathways that transfer data between the CPU and its peripherals. The most common type of bus is the PCI bus, which allows for communication between the CPU and the peripherals on the motherboard. Other types of buses, such as USB, FireWire, and SCSI, are used to connect external devices to the CPU.
The CPU communicates with peripherals through a combination of hardware and software. The hardware includes the bus, which is a collection of electrical lines that connect the CPU to peripherals, and the controller, which is a special-purpose chip that handles communication between the CPU and peripherals. On the software side, the CPU uses an operating system to manage the communication between it and the peripherals. The operating system includes device drivers, which are programs that allow the CPU to access the peripherals.
