7 Managing and sharing information
Drives are digital storage devices that help you store, manage, share, and access information. Your
computer has an internal hard drive that stores your computer's software, operating system, as well
as providing storage for all of your personal files.
For added capacity or functionality, connect an external drive (purchased separately), such as an
optical drive or hard drive, or insert a memory card to import information directly from your phone or
camera. A USB flash drive, connected to the Universal Serial Bus (USB) port on your computer, also
allows quick data transfer. Some devices use the computer's power to run; others have their own
power source. Some devices come with software that must be installed.
NOTE: For information about connecting external wireless devices, see Connecting to a network
on page 19 .
NOTE: For more information about required software and drivers, or to learn which computer port to
use, see the manufacturer's instructions.
Using a USB device
Most computers have more than one USB port, because this versatile interface allows you to connect
numerous kinds of external devices—such as a USB keyboard, mouse, external drive, printer,
scanner, or USB hub—to your computer.
Your computer has more than one type of USB port. See Getting to know your computer on page 3
for the types of USB ports you have on this computer. Be sure to purchase devices that are
compatible with your computer.
