For example, most printers can't do much on their own and only become functional when connected to a computer system. Peripheral devices depend on the computer system. (Zandbergen, n.d.)Peripheral devices fall into three general categories:1. Input devices, such as joysticks and digital cameras (COMPUTER HOPE, 2013)2. Output devices, such as a speaker and a 3D printer (COMPUTER HOPE, 2013)3. Storage devices, such as a hard drive or USB flash drive and refer to any hardware that can hold information (COMPUTER HOPE, 2013). Some devices fall into more than one category. Let's consider a CD-ROM drive; you can use it to read data or music (input), and you can use it to write data to a CD (output). Peripheral devices are not essential for the operation of the computer. For example, you can unplug a printer and your computer will continue to work perfectly. However, remove a desktop computer monitor and it becomes virtually unusable.Performance
