A more thorough explanation:

Definition: Call of the roll is a process of taking attendance by calling out the names of individuals on a list.

For example, in a classroom, the teacher may take the call of the roll at the beginning of each class to ensure that all students are present. The teacher will call out each student's name, and the student will respond with "present" or "here."

Another example is during a meeting, where the chairperson may call the roll to determine if there is a quorum, which is the minimum number of members required to conduct business.

The call of the roll is a simple and effective way to keep track of attendance and ensure that everyone is accounted for.
