Connecting to a network
Your computer can travel with you wherever you go. But even at home, you can explore the globe
and access information from millions of websites using your computer and a wired or wireless
network connection. This chapter will help you get connected to that world.
Connecting to a wireless network
Wireless technology transfers data across radio waves instead of wires. Your computer may be
equipped with one or more of the following wireless devices:
●
Wireless local area network (WLAN) device—Connects the computer to wireless local area
networks (commonly referred to as Wi-Fi networks, wireless LANs, or WLANs) in corporate
offices, your home, and public places such as airports, restaurants, coffee shops, hotels, and
universities. In a WLAN, the mobile wireless device in your computer communicates with a
wireless router or a wireless access point.
●
Bluetooth device—Creates a personal area network (PAN) to connect to other Bluetooth-
enabled devices, such as computers, phones, printers, headsets, speakers, and cameras. In a
PAN, each device communicates directly with other devices, and devices must be relatively
close together—typically within 10 meters (approximately 33 feet) of each other.
