The purpose of the discovery phase in the is for a sta and an ap to recognize each other, agree on a set of security capabilities, and establish an association for future communication using those security capabilities.

The answer to this question is RSN(Robust Security Network).

Explanation:

The term RSN stands for Robust Security Network. This security network that allows you to create RSNAs(robust security network associations). It associates with STA and AP. Which provide the secure communication. It also provides authentication or association to the 4-Way Handshake.

STA used to AP(access point) sometimes, in which case an STA is any device communicating via the 802.11 protocol. So RSN provides security capabilities and establishes an association for future communication using those security capabilities.

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?
