1.- This one is about wireless:
Is the following table correct?
802.11a > 54 Mbps >5-GHz
802.11b > 11 Mbps >2.4-GHz
802.11g > 54 Mbps >5-GHz
802.11n > 100+ Mbps >2.4/5-GHz


2.- Network (Ethernet cables, all of them UTP):
CAT5 100Mbps
CAT5e 1Gbps
CAT6 10Gbps


Feel free to edit/add extra info.
thanks!

802.11g works in the 2,4 Ghz range

 

Thanks, that's what I thought, but the Meyers book, in the glossary has the above (incorrect) information.

 

There are few mistakes in all books. Meyers has an errata website which corrects all the mistakes, I never checked for any MS errata sites though.

 

Not saying you'll have problems but when I did my A+ and N+ I always used to get confused with the wireless characteristics as I tried remembering them in alphabetical order as you've listed. The way I got to remember was to think of the word B(e)GAN:

802.11b > 11 Mbps >2.4-GHz
802.11g > 54 Mbps >2.4-Ghz
802.11a > 54 Mbps >5-GHz
802.11n > 100+ Mbps >2.4/5-GHz

Then all I had to remember was the first one was slowest but shared a frequency with the next one and the rest fell into place

 

There are lots of clues in the way they are written. If you start at the bottom, as in the slowest and work you way up it will look like this.

10 Base 5
10 mbps
500 meters the clue being 10 and the 5 to associate with 500 and 10 mbps....Thicknet if you can rem that

10 Base 2
10 mbps
185 meters 10 mbps, LESS than 2 so 185 meters thin-net coax 30 devices per segment

10 Base T
10 mbps
100 meters T for twisted pair, 10 mbps, 100 meters the odd one to remember as it has no association

100 Base TX
100 mbps
100 meters T for twisted cat 5, 100mbps in the 100 base TX, 100 meters in the 100 base tx

1000BaseT
1000mbps
100 meters 1000mbps/1 gbps, t for twisted pair, 100 meters


That is how i remembered it.




Wireless.....

G is backward compatible to B, N as well...so far and all have MAC filtering as well as an option.

Hope it helps

Edit...All the T's here are 100 meters as well so that is easy to remember

Wish i could tell you more about the test but there is a NDA on it and i respect that.
