Wireless Network
wireless networking is a way to connect computers or other devices, either in your home or across long distances, using infrared light or radio frequency signals. Devices commonly used for wireless networking include desktop and laptop computers, hand-held
computers, personal digital assistants (PDAs), mobile phones, pen-based computers, and pagers. Wireless networking is useful in many situations. For example, if you are away from your computer, you can use your mobile phone to read and respond to e-mail. If you travel with a laptop computer, you can connect to the Internet through wireless access points installed in airports, hotels, and other public locations.
You can also synchronize data and transfer files between two computers or between a computer and another device. Wireless local area networks (WLANs) are often used in corporate or campus buildings, or in airports. WLANs are also used in home or small office networks. There are two type of WLAN
A local area network that uses access points to connect computers and devices on the network. This is also called an infrastructure network.
A computer-to-computer local area network (also called an ad hoc network) with several users in a limited area, such as a conference room. This type of network does not use an access point.
When your computer is in range of a wireless network, a message will appear in the notification area on your screen. You can click the message to see a list of wireless networks and then select a wireless network to connect to. if you are traveling, you can get a list of available wireless networks in the area where you will be staying by entering the city, state or province, and postal code for that area.
Sometimes when you connect to a wireless network, you are prompted to enter a network key (also called a WEP key, or wired equivalency privacy key). This key is like a password that you need to gain access to the network. In some cases, the key might be provided to you by the network administrator. In other cases, you might be asked to create a key.
