Peripheral devices.

– 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.

Peripheral devices.

– Legacy connections.» Serial port (DB-9).

» Parallel port (DB-25).

– Semi-legacy connections.» Personal system/2 (PS/2) ports.

– Current connections.» Small Computer System Interface (SCSI).

» USB.

» IEEE 1394 (FireWire).

» Wireless (Bluetooth).

» Network (Ethernet).

» Tip ring sleeve (analog).

– Other connections.» Manufacturers of peripheral devices may require proprietary

connection types; when they do, they also provide the means to

accomplish the connections.

Peripheral devices.

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.

– Input devices.» Mouse and keyboard.

» KVM = keyboard video and monitor switch.

» Scanners and barcode readers.

» Biometric devices.

» Game pads and joysticks.

» Microphones.

» Digitizers (capturing an analog signal in a digital format).

– Output devices.» Printers.

» Speakers.

» Display devices.

– Multimedia devices.» Digital cameras, camcorders, and webcams.

» MIDI = Musical Instrument Digital Interface.

Peripheral devices.

Peripheral devices.

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).
