- 8. Page 8 When connecting a peripheral device, always read the manufacturer’s installation instructions first. The major reason for this is to determine when the driver gets installed on the PC. Some OSs are very peculiar about some driver installations. Installing the driver in the incorrect order can result in frustration due to loss of functionality. Peripheral devices.

They have a connection to the computer and utilize drivers to communicate with the OS and other peripherals. Topic What are peripheral devices? Summary There are many ways in which they may connect to the PC. Some wired connections include: through a serial port, through a PS/2 port, and via a USB port. Peripheral devices may also connect wirelessly. If manufacturers require a proprietary type of connection, it is up to them to provide the means of making the connection. Read the installation instruction before installing to reduce frustration. How peripheral devices connect. They can be broken out into three basic categories: input devices (e.g., keyboard/mouse, KVM, scanners), output devices (e.g., printers, video displays, speakers), or multimedia devices (e.g., camcorders, webcams, MIDI). Examples of peripheral devices.
