Define an extended service set.

Answer:

Abbreviated as ESS, Extended Service Set is a component of the IEEE $8$ architecture that extends the range of mobility to a single Basic Service S Extended Service Set $($ESS$)$ is a set of two or more BSSs that form a sing network.

An extended service set $($ESS$)$ is one or more interconnected basic servic and their associated LANS. Each BSS consists of a single access point $($A with all wireless client devices istations, also called STAS$)$ creating a local $802\mathrm{.}11$ wireless LAN $($WLAN$).$ To the logical link control layer $($part of layer layer OSI Reference Model$)$ the ESS appears as a solitary BSS at any on

A set of one or more interconnected BSSs and integrated LANs that appe BSS to the LLC layer at any station associated with one of these BSSs$.$

What is the difference between TKIP and CCMP$?$

Answer:

Temporal Key Integrity Protocol $($TKIP$)$

Counter Mode$-$CBC MAC Protocol $($CCMP$).$

TKIP is designed to require only software changes to devices that are impl the older wireless LAN security approach called Wired Equivalent Privacy $($ provides two services:

Message integrity: TKIP adds a message integrity code $($MIC$)$ to the $802\mathrm{.}1$ frame after the data field. The MIC is generated by an algorithm, called Micl
