Peripheral devices are commonly referred to as I/O (input/output) devices. These devices allow information to be communicated between the CPU and the outside world, such as the keyboard, mouse, printer, and more. Option A (CPU) is incorrect as it is the central processing unit, which is responsible for processing instructions and managing the flow of data within a computer. Option B (control device) is too general and doesn't specifically refer to I/O devices. Option D (register) is a component of the CPU, used for temporarily storing and manipulating data.
