Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which Wi-Fi standard is the fastest?
A
802.11a
B
802.11ac
C
802.11g
D
802.11n
Explanation: 

Detailed explanation-1: -The theoretical maximum 802.11ac speed is eight 160MHz 256-QAM channels which are each capable of 866.7 Mbps. So, that means the grand theoretical total nears 7 Gbps! However, in the real world, you probably won’t be using eight channels (more like two or three), giving you a real-world maximum between 1.7-2.5 Gbps.

Detailed explanation-2: -The 802.11ac standard declares a maximum theoretical connection speed of up to 7 Gbps. It has become possible to significantly increase the data transfer rate by increasing the channel width to 80 MHz, increasing spatial streams, and supporting the new modulation 256-QAM.

Detailed explanation-3: -802.11ac is also referred to as Wi-Fi 5, using the nomenclature derived by the Wi-Fi Alliance. Although still considered current to a certain degree, 802.11ac is being displaced by the latest standard, 802.11ax, also known as Wi-Fi 6.
