The 2/2 time signature, also known as "cut time" or "alla breve," is a meter in music that indicates two beats per measure where the half note gets the beat. It's commonly used in faster music because it allows musicians to mentally divide measures in half, simplifying the counting of quick tempos. One way to visualize 2/2 time is to think of a regular 4/4 time signature (which is the most common time signature and is sometimes called "common time") and imagine it being "cut" in half. In 4/4 time, there are four beats per measure, and the quarter note gets the beat. When you "cut" this in half, you get 2/2 time: two beats per measure, with the half note getting the beat.
