There are many different peripheral devices, but they fall into three general categories: Input devices, such as a mouse and a keyboard. Output devices, such as a monitor and a printer. Storage devices, such as a hard drive or flash drive. Source: Study.com
Input device
Fun fact: You can use an input device such as a mouse or keyboard to give a device commands; to tell the device what you want it to do.
Output devices
In a nutshell 🐿️, computer monitors enable you to see what you are accomplishing using the computer itself.
storage device
Fun fact: External storage devices make it easy to copy large files (e.g. videos and multimedia presentations) between devices.
External storage devices can also be used to back up your important files — although it should be noted that external storage devices can become inoperable (i.e. turn into pumpkins 🎃) for no particular reason.
