A more thorough explanation:

Definition: Concurrent (adjective) means happening at the same time or having authority over the same matters.

Examples:

• During the concert, there were concurrent performances on two different stages.
• The two courts have concurrent jurisdiction over this case.

The first example shows how concurrent can be used to describe two events happening simultaneously. In this case, there were two performances happening at the same time during the concert.

The second example shows how concurrent can be used to describe two entities having authority over the same matter. In this case, two courts have the power to make decisions about the same case.
