Difference between prorogation of the Legislature and an adjournment of a meeting of the Legislature

A session is the period of time between the meeting of a Parliament, whether after, a prorogation or dissolution, and its prorogation. .... During the course of a session, either House may adjourn itself of its own motion to such date as it pleases. The period between the prorogation of Parliament and its re-assembly in a new session is termed a 'recess'; while the period between the adjournment of either house and the resumption of its sitting is generally called as 'adjourned'.
