I think you're referring to NBA and College Basketball games. NBA games consist of four, 12-minute quarters while college Basketball games consist of two, 20-minute halves. I'm not sure what the reasons are other than the level of talent of each league.
there are 4 quarters
Professional basketball (NBA and FIBA) has its games divided into quarters, as do high school ball (at least in my experience). NCAA basketball games are divided into two 20 minute halves, as are many recreational leagues. So, does basketball have quarters? Sometimes.
In the NBA, the games consist of 48 minutes with 12 minute quarters. In pickup basketball, it really depends on what the players want.
College basketball games are divided into halves.
College Basketball games are played in two halves.
