Why are the keyboard and mouse a peripheral?
Many computer users are surprised to learn that a computer can run without a keyboard and a mouse. Both of these devices are not required for a computer to run, which is why they're considered peripherals. In fact, many of the servers at data centers have no keyboard or mouse and are often managed remotely.

When you buy a new desktop computer, it comes with a keyboard, mouse, sound card, power plug, and may also include a monitor. A laptop computer includes everything, so it only includes a power cord.
