Men's vs. Women's
Look, the main difference between men's and women's college basketball is the attention the programs and players get. The guys get most of the TV time and unless you go to one of the biggest programs in the country (think UConn or Tennessee), they'll often draw bigger crowds at games as well. But not always.
There are some women's programs that outdraw the men's programs (source). (We hear Stanford's women's b-ball games are pretty popular...) More importantly, the women's game has also started to explore ways to grow larger and increase popularity (source).
The number of scholarships offered to men and women college basketball players are very similar (source). Women have access to the same training facilities and play on the same court as the men's teams, too.
Technically speaking, the difference between the men's and women's game comes down to size and speed. The women's ball is slightly smaller than the men's ball. Men get a thirty-five-second shot clock, while women only get a thirty-second shot clock.
Rule-wise, pretty much everything else is the same, from the length of the game down to the size and dimensions of the court (source).
