Webcam  35
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
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 up the webcam, see “Using the webcam”.
Network
A network allows you to connect your devices with each other and to the
internet. These devices include computers, tablets, phones, printers, and
other peripherals. You can set up your network using cables (LAN) or using
wireless devices (WLAN). Networks can be set up using Ethernet, Wi-Fi,
WWAN, Bluetooth, and so on.
Local Area Network (LAN)
Devices are connected using Ethernet cables and cover a relatively small
area, generally within a house or a building.
Wireless Local Area Network (WLAN)
Devices are connected wirelessly and cover a relatively small area, generally
within a house or a building. The wireless connection used for setting up
WLAN is generally Wi-Fi (802.11x where x refers to the different 802.11
protocols).
Wireless Wide Area Network (WWAN)
Also known as Mobile Broadband, this service is generally provided by the
phone companies for use on mobile devices. A mobile device or laptop
must support WWAN technology to connect to this network.
Wireless Personal Area Network (WPAN)
Devices are generally connected wirelessly using Bluetooth, RF, Near-Field
Communication (NFC), and so on. This type of network generally operates
within a few feet of the devices. To connect your computer or tablet to the
internet, see “Connecting to the internet”.
