Every day we see improvements and innovations in technology. Telephones and computers can be operated without any need for a wired connection; instead, all you need is an antenna and receiver, and a wireless protocol compliant device to send and receive signals. It has become all the more important to make sure security loopholes are plugged and secure communication is enabled. This course on network WiFi covers the types of WiFi standards, their origin, and the security involved with these WiFi networks.
