THE INTERNET
Connecting to the internet
You can connect to the internet either via an internet cable or wireless.
Most newer desktop computers include a Wi-Fi card but the early desktop computers don't have a Wi-Fi card and so doesn't have a wireless connection feature and so connecting to the internet is solely by a cable or you will have to purchase a USB wireless adapter in order to be able to connect to wireless networks.
You can connect a USB wireless adapter to a desktop computer if wireless connection is the only option available for you (absence of a router or switch provided by an internet service provider -ISP or USB modem)

If your desktop computer doesn't have the Wi-Fi card, you will have to purchase a USB wireless network adapter similar to the above figure and insert into the USB port of the computer.
This will make it possible to see available wireless networks for you to connect to.

Forgetting a wireless network
To forget a wireless network simply means delete a wireless network profile.When you forget a wireless network, the computer device will remove that particular network from saved networks list and it will not remember the password and other network credentials that were previously saved. The next time you connect to a forgotten wireless network, you will be asked the password before being connected to. If you temporary share your hotspot/wireless network on a friend's computer, you can forget the wireless network once the device finishes using the network. Otherwise the next time your wireless network is on and the device is in the vicinity, the device can automatically connect to your wireless network without your knowledge.
