Computers have to have output devices in order to relay information back to other devices for its use. If computer information remaines exclusively in the computer, then it is useless, because nothing is done with it. Even in the case of stored data, the information is often relayed to another computer with output devices, or directly to an output device, so that it can affect the outer world.Output devices include: screens, electric motors, cars, lights, speakers, etc.Without output devices, it would be, in addition, impossible to determine the inner workings of computers without output devices, as any modifications to allow the viewing of the information/functionality would be considered an output device.
Output devices for a computer include monitor, printer etc. which are used for displaying or printing the result of execution of a program on the computer. Input devices include mouse, keyboard or a scanner which are used for data or control inputs. - Neeraj Sharma

In the broadest sense, the items you mention are all peripherals. Peripherals are items that are used by a computer but are not always necessary and often don't come with the computer.Now, looking at the example items individually, they are input and output devices. Speakers and printers are output devices. A speaker provides output in the form of sound, while a printer provides output in printed form on paper. A webcam is an input device, since it converts images from the real world into digital data a computer can use.
