Computer Networking facts about the Dual-Band Wireless PCI Adapter
A Dual-Band wireless PCI adapter card allows your notebook computer to communicate with the present wireless networking standards and also prepares you for the future.
The Dual-Band PCI card connects with the 2.4 GHz, 802.11b wireless networks present in today's homes and businesses and with also a growing number of 5GHz, 802.11a networks that are now spreading across the country. The Dual-Band card supports 152-bit data encryption thus keeping your wireless computer networking communications secure.
The 802.11a standard is almost 5 times faster than the 802.11b but is not as popular yet. Its use is increasing especially where higher speed connections are required.
Connecting two or more Computers using Network Interface Cards (NIC)
If your Networking has more than two computers, you will need a hub to connect the other computers to the Host computer. For example, if your Networking has two computers along with the Host computer, you will need a 2-port Hub to connect the two computers to the Host computer.

If you will be networking only two computers, you will not need a hub, you will only need a Cat5 crossover cable along with a Network Interface Card (NIC) for each computer.

Wireless Cheap Computer Networking
If you are using a dial-up connection, wireless networking is not recommended. Wireless Networking should only be used with a high speed internet connection such as DSL and cable.
Using DSL or cable is dependent on their availability in your area.
Having Wireless Networking allows you to be able to share your internet connection with other computers without having to run network cable in your house.
It also makes moving computers around much easier. For example, If you have a laptop computer with a wireless network card, you can use it from any room in your house.
Final Thoughts on Cheap Computer Networking
Wireless Networking is the best way to go but, unfortunately, neither DSL nor cable are available in some areas. Therefore, some of us are 'stuck' with a dial-up connection and will have to use wired computer networking.
