Please explain the purpose of the President having a leader in each department, what term is used to describe this group and what term is used to mean the leader of each department

Purpose:

Term for group

Term for department leader.

They pick qualified people to do certain work, expect them to do their best and then report back on what they have accomplished. The top person, such as the President, will probably make the final decisions. But he or she can't possibly do all the day-to-day work alone, henceforth the Cabinet.

Term for group; Cabinet

Term for department leader; Cabinet ministers or secretaries. (most commonly secretaries.)

Hope this helps!
