WAN question

What is the difference between 802.11b, 802.11b/g, and 802.11a/b/g wireless cards (for laptops). My scool says I need a 802.11b card but does that mean the 802.11b/g card and it will work also?

g is backward compatable to b

I would suggest getting a g one, since there isn't that big of a price gap, and 802.11g is definitly the future.

Actually G is kinda the past
the new thing is SuperG 108Mbps

I'm seeing that a lot of the laptops in the stores have the g ones. Now, the g ones will work on a network that requires the a? Sorry, I have no clue on this wireless stuff.

No, 802.11g equipment will not necessarily be compatible with 802.11a equipment, this is due to the fact that they operate on different frequencies/bands.
In 802.11b/g equipment, the transceiver operates on a band in the 2.4 GHz range. In marked contrast, 802.11a transceivers operate on a band in the 5 GHz range. So to have both b/g AND a you will have to have a transceiver capable of both ranges. Most equipment does not support both. Most equipment that does suppot both will have something like "dual band" or something similar in the tagline.

The primary purpose of the DATA statement is to give names to constants; instead of referring to pi as 3.141592653589793 at every appearance, the variable PI can be given that value with a DATA statement and used instead of the longer form of the constant. This also simplifies modifying the program, should the value of pi change.
