– Peripheral devices:
» Are not built into the computer.
» Are external to the system.
» Have a connection to the PC:
• Via a wired connection.
• Via a wireless connection.
» Have a main purpose:
• To improve input.
• To improve output.
• To extend functionality.
• To increase productivity.
• To expand enjoyment.
– Peripheral devices use device drivers.
» Device drivers tell the host operating system how the peripheral
device is supposed to interact with the system.
» Device drivers tell the OS how the peripheral devices interact
with each other.
» The manufacturer of the peripheral device provides the driver.

» Manufacturers of peripheral devices may require proprietary
connection types; when they do, they also provide the means to
accomplish the connections.

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.

They are add-on components that are external to the PC. They add
capabilities that were not present when the system was built. 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).
