Webcam
A webcam allows you to capture videos and photos, and can also be used
for video calls. Your display may have a built-in webcam or you can connect
and external webcam to your computer. Camera quality is mainly defined by
the number of pixels it can capture.
To use the webcam, you must install webcam drivers and software. If you
ordered the webcam along with your computer, the drivers and software are
generally installed when you receive your computer.
For more information on using the webcam, see
Using the Webcam .
ExpressCards
ExpressCards can be inserted into the ExpressCard slot available on some
computers. Devices that are available in ExpressCard format are TV-tuner
cards, memory cards, communication devices, and so on.
When your computer ships from the factory, the ExpressCard slot is covered
or a blank card is inserted in the slot to prevent dust from entering the
computer. You must remove the blank to install an ExpressCard.
