Now, walk into any cafe store or other public places, has wireless connectivity, you're not alone. Currently, more and more places will have free wireless connectivity, 241,506 WiFi hot spots are scattered throughout 134 countries, and some of those “spots” are entire cities.
These hot spots usually connect to the larger Internet community by cables or wires and broadcast the Internet signal wirelessly to individual computers using radio frequencies. Many personal computers pick up that signal using a Wireless Internet card, a small device about the size of a credit card.
Wireless Internet cards, are one of the many types of adapter cards that add capabilities to your computer, also known as Local Area Network, or LAN, cards. Other adapter cards can enable teleconferencing, improve sound systems or download photos from a digital camera.
Wireless Internet cards come in several forms, different cards exist for laptops, desktops and PDAs. Many computers come with one preinstalled, but they can also be purchased relatively inexpensively and self-installed or simply inserted into a slot on the side of the computer.
The sheer number of WiFi hot spots has made wireless Internet cards even more desirable. Initially used mostly in businesses or homes so that multiple people could share an Internet connection, they are a hot commodity for anyone with a computer, especially with entire cities going wireless.
Wireless Internet cards make people doing business or others more convenience.
It is such a good thing for computer.
