Which network type utilizes WEP security?

WEP, or Wired Equivalent Privacy, is a security protocol that was introduced with the original 802.11 standard for wireless networks. The key feature of WEP is that it was designed to provide a wireless local area network (WLAN) with a level of security comparable to that of a wired network.

In the context of the options presented, the correct choice is associated with 802.11b, as this was one of the earliest Wi-Fi standards to implement WEP as its security mechanism. Although 802.11n and 802.11g can utilize WEP for backward compatibility, they are more commonly associated with stronger security protocols such as WPA (Wi-Fi Protected Access) and WPA2, which were introduced after WEP was largely deemed insufficient in terms of security.

In summary, the association of WEP with 802.11b highlights its role as one of the foundational technologies in the evolution of wireless networking, making it the correct answer in this context.
