802.11 Wireless Networking

Question 1

802.11a IEEE Standard

Answer 1

5 GHz, 6-54 Mbit/s, Wifi 1

Question 2

802.11b. IEEE Standard

Answer 2

2.4 GHz, 1-11 Mbit/s, Wifi 2 (like dial-up internet—super slow but reliable)

Question 3

802.11g IEEE Standard

Answer 3

2.4 GHz, 6-54 Mbits/s, Wifi 3. (is like early broadband—faster but still not great by today’s standards)

Question 4

802.11n IEEE Standard

Answer 4

2.4 GHz / 5 GHz, 72-600 Mbit/s, Wifi 4, Uses MIMO (Supports HD streaming and gaming without constant buffering).

Question 5

802.11ac IEEE Standard

Answer 5

5 GHz, 433-6,933 Mbit/s, Wifi 5, Uses MU-MIMO (Fast Wi-Fi for the whole house! Stream 4K, game online, and use multiple devices smoothly)

Question 6

802.11ax IEEE Standard

Answer 6

2.4 GHz / 5 GHz / 6 GHz, 574-9,608 Mbit/s Wifi 6. (You’re in a crowded stadium, airport, or school, and Wi-Fi still works great! 802.11ax (Wi-Fi 6) is designed for tons of devices, giving everyone fast speeds and low lag)

Question 7

802.11be IEEE Standard

Answer 7

2.4 GHz / 5 GHz / 6 GHz 1,376-46,120 Mbit/s. Wifi 7

Question 8

802.1Q Trunking

Answer 8

A single cable carries multiple VLANs, letting switches separate traffic while using fewer cables. ( A single cable carries multiple VLANs, letting switches separate traffic while using fewer cables.)

Question 9

Port Tagging

Answer 9

adds VLAN IDs to network traffic so switches know which VLAN data belongs to, keeping networks organized and secure.

Question 10

Trunking

Answer 10

allows multiple VLANs to share one network link by tagging traffic, letting switches send data to the right VLAN.

Question 11

802.3ad

Answer 11

Link Aggregation Control Protocol (LACP) is used with 802.3ad to automatically combine multiple network links into one, improving speed and reliability.
