In this presentation we will…..
Explain how I/O devices function inside a
computer system
Identify the spectrum in which I/O devices
can affect a computer’s performance
List I/O devices most major brands and
their equivalent costs.
Make recommendations to an array of
users that will help make their life easier

How the products work and
function in a computer system.
Input Devices:
Keyboard
Mouse
Scanner
Digital camera
Joystick

A hardware device
that sends information
into the CPU. Without
any input devices a
computer would
simply be a display
device and not allow
users to interact with
it, much like a TV.
Output Devices:
Monitor
Printer
Speakers
Sound card
Video card
Any peripheral that
receives and/or
displays output from a
computer.
