What is WiFi?
Wireless connectivity, often known as WiFi, is the technology that allows a PC, laptop, mobile phone, or tablet device to connect at high speed to the internet without the need for a physical wired connection. WiFi (pronounced “Why-Fy”) is a term that was coined by a branding company in 1999 as a name which would be easily recalled, due to its similarity to the then well-known term “hi-fi”.
The technology uses radio signals to transmit information between your WiFi enabled devices and the internet, allowing the device to receive information from the web in the same way that a radio or mobile phone receives sound.
Wireless security is the prevention of unauthorized access or damage to computers using wireless networks. The most common types of wireless security are Wired Equivalent Privacy (WEP) and WiFi Protected Access (WPA). WEP is a notoriously weak security standard.

Which type of security is best for WiFi?
Setting up WEP, WPA or WPA2 wireless security
Security |
Rank |
| WEP Wired Equivalent Protocol | Basic |
| WPA Personal WiFi Protected Access® Personal | Strong |
| WPA2 Personal WiFi Protected Access® 2 Personal | Strongest |
| WPA2/WPA Mixed Mode | WPA2: Strongest WPA: Strong |

Assessment:
- http://wififorbeginners.com/quizzes/module-1-quiz/
- The students will create a poster to inform the public on WiFi safety
Enrichment/Follow-up:
The students will research on the following questions:
- What are the benefits to “the cloud” and what are the risks?
- What is an easy rule to remember with USB devices? (If it’s not mine, don’t touch it-could be carrying malware/viruses).
- What might the storage of data look like in the future?
- Is there something better than the cloud?
- What do you prefer a USB, a school network storage drive, or the cloud? Why do you prefer the method? What are the positives and negatives of your choice? Have you ever experienced an issue or problems retrieving your stored information? How was it handled?
- If you do not have experience in data storage yet, What is the best practice to store data a USB or cloud storage?
