It's means disabling 3G (cellular) internet. When it's off you can only access the web via WiFi. It's good if you're on a limited data plan and don't want to waste it. If you have unlimited data, you don't have to worry about it.

Cellular data uses the data plan (internet through the cellular antenna / tower system) So if you turn it off, you will not have internet connection (if 3G is also turned off)

3G is also for data transfer, but its a different technology than Cellular Data, and is much faster than Cellular Data. 3G is not available everywhere all the time so your internet may not work if you only turn on 3G in some locations.

as you probably know, cellular data is any non-WiFi internet source, for GSM iPhone it would be GPRS, Edge, or 3G. for CDMA, it would be 1X or 3G.
turning off cellular data will prevent you from accessing the internet, unless you are connected to WiFi. people would usually turn off cellular data to prevent international roaming charges (although you can turn off data roaming for this), or to prevent going over possible data limits that your carrier has

so Iphones can do all their program stuff on wifi, which only works if you are near the wifi base, like the same building. Celluelar data is connecting to the network anywhere the company has service in the nation. Turning it off means it will only do internet and network in a wifi area
