I learnt some information about networks in Wiki,and I am so curious about naming IEEE standard networks. As far as I know:
The standard name of Wifi is 802
The standard name of Ethernet is 802.3
The standard name of Wireless LAN is 802.11,and 802.11a/b/g/n/ac after 802.11
I want to ask
Why do we always use the "802" to name the standard network? Why do we insist on using these three numbers,instead of other number like "123","456" ,or "789" these three numbers?
Why did we name standard name of Ethernet 802.3? Why don't we name it 802.2,or 802.9,is that .3 means the ethernet is the "third" standard network we discuss?or?
802.11ac is faster than 802.11n,
802.11n is faster than 802.11g,
802.11g is faster than 802.11b,
so 802.11a/b/g/n/ac is like the evolution of 802.11, I want to ask why should we use "a,b,g,n and ac" to describe the evolution of 802.11? why don't we just use a,b,c,d,e,f to describe the evolution of 802.11? Easiser to remember and determine which is faster.
