Explanation / Answer

1. WPA2

WPA2 helps an employee continue to run his or her database while moving his computer from a building to another as both buildings have WPA2 access which is secured network and stands for "Wifi Protected Access II".

2. Autonomous AP

A wireless home router are commonly used as home wireless networks. Home routers generally have one autonomous AP to connect all home computers.

3. MIMO

MIMO stands for "Multiple Input Multiple Output". It is a method for multiplying the capacity using multiple transmissions. It is basically an essential element of wireless communication and is used for enhancing the performance.

4. Beacon

Beacon frames constitutes among one of the management frames in wireless networks as it contains all the information about the network. It is announced periodically to announce the presence of wireless networks.

5. Control

Control frames are used to facilitate the exchange of data frames in wireless networks as they are transmitted with the basic rates and are also used to clear the channel.

6. WEP

WEP stands for "Wired Equivalent Privacy" is least secured among all security modes because it uses two set of keys to encrypt each bit of information which can easily be broken down and information can be obtained.

7. IEEE 802.1X

RADIUS stands for "Remote Authentication Dial-In User Service" which uses IEEE 802.1X as a standard because they use radius protocols to communicate with radius servers such as NPS servers.

8. Linksys Router Settings

This window shows SSID, Wireless password and administrative password.
