Wwan Card
This card is identical to the WLAN
card or the Wi-Fi card. And is not installed on every laptop, rather it is more found on the
business end laptops or the gaming laptops. Wwan is commonly used for corporations or larger sized
businesses running cross country or worldwide servers or networks. Same goes for the Gaming based
laptops like the Alienware m17x which uses Wwan to Game Online. A lot of manufacturers of laptop
motherboards will apply the port contact pads but do not install the port due to specific laptop case
specs and the port not fitting certain laptop case configurations.
Webcam
Laptop webcams have not had a lot
of improvement in the past few years, I can’t think of any laptop model offhand that has a good
Webcam. If a laptop does have one, it will usually be located on the upper portion of the front of the
screen. It will usually have a microphone located right nest to it or nearby. These are almost always
stationary cameras and do not move in any way, though there are models that have movable cameras.
Acer has some models that used a spinning camera. It could rotate up or down, though not left or right.
PC Slot Card/SD/MMC
These will be found on
both the sides and the front of certain laptops, more commonly found on newer laptops. They
allow the use of external components such as Memory cards, Ethernet Network cards, Modems and
similar.

every laptop ever released. It is used to connect an external monitor or viewing device to. It is
Video Out, not Video In. The most common thing to connect to this port is a Desktop Computer
Screen.
HDMI/Other
