7.1)

BSS (Basic Service Set) is a basic building block of  802.11 wireless LAN.

It is the wireless station that executing the similar competing and the MAC protocol for accessing a similar wireless system is shared.

7.2)

The Extended Service Set is one of the basic components of IEEE 802.11 WLAN architecture which increases the mobility range to the individual BSS (Basic Service Set).

An ESS is the set that contains two or more than two Basic Service Sets

that forms an individual sub-network.

7.3)

The IEEE 802.11 service has the MAC layer implement which falls in two categories:

Service Station - 802.11 standard has defined the services which is providing the functions among the stations.

It includes the following components:

Distribution System Service - It defined by the 802.11, provides the functionality across the distribution system and access point also provides the DSS.

It includes the following components:

7.4)

It either may be or either not be a wireless network.  

Because distribution system has these three things:

7.5)

Association agrees on the set security capabilities to use.

It also allows the mobile node which has made the transition to identifies itself to the AP (Access Point) within a BSS so that's why the nodes can be participated in the data exchanges with  another mobile nodes.

7.6)

The IEEE 802.11i are addresses the three types of security areas:

1) authentication,

2) key management,

3) data transfer privacy.
