Operates in the 2. 4 GHz frequency band and offers speeds of up to 54 Mbps.

hard
 
Question 3 / 20

Operates in the 2. 4 GHz frequency band and offers speeds of up to 11 Mbps.

hard
 
Question 4 / 20

Operates in the 2. 4 GHz or 5 GHz frequency bands. The typical expected data rates are 100 Mb/s to 600 Mb/s with a distance range of up to 70 meters. It is backward compatible with 802. 11a/b/g devices.

hard
 
Question 5 / 20

Can simultaneously operate in the 2. 4 GHz and 5. 5 GHz frequency bands providing data rates up to 450 Mb/s and 1. 3 Gb/s (1300 Mb/s. ) It is backward compatible with 802. 11a/b/g/n devices.

hard
 
Question 6 / 20

Also known as "WiGig". It uses a tri-band Wi-Fi solution using 2. 4 GHz, 5 GHz, and 60 GHz and offers theoretical speeds of up to 7 Gb/s.

hard
 
Question 7 / 20

What is one main characteristic of the data link layer?

medium
 
Question 8 / 20

__________ a method of converting a stream of data bits into a predefined "code”.

medium
 
Question 9 / 20

As data travels on the media in a stream of 1s and 0s how does a receiving node identify the beginning and end of a frame?

medium
 
Question 10 / 20

What is true concerning physical and logical topologies?

hard
 
Question 11 / 20

What are two characteristics of 802. 11 wireless networks?

medium
 
Question 12 / 20

If a data signal is absent and therefore the media is free, the device transmits the data. If signals are then detected that show another device was transmitting at the same time, all devices stop sending and try again later. Traditional forms of Ethernet use this method.

hard
 
Question 13 / 20

If the media is free, the device sends a notification across the media of its intent to use it. Once it receives a clearance to transmit, the device then sends the data. This method is used by 802. 11 wireless networking technologies.

hard
 
Question 14 / 20

All nodes compete for the use of the medium but have a plan if there are collisions.

hard
 
Question 15 / 20

Each node has its own time to use the medium.

hard
 
Question 16 / 20

Used by the MAC sublayer to identify the beginning and end limits of the frame.

medium
 
Question 17 / 20

Used by the MAC sublayer to identify the source and destination nodes.

hard
 
Question 18 / 20

Used by the LLC to identify the Layer 3 protocol.

medium
 
Question 19 / 20

____________ enables a number of nodes to communicate by using the same shared media. Data from only one node can be placed on the medium at any one time. Every node sees all the frames that are on the medium, but only the node to which the frame is addressed processes the contents of the frame.

hard
 
Question 20 / 20

In a _________________, each node in turn receives a frame. If the frame is not addressed to the node, the node passes the frame to the next node.
