Hint:A Joint Session is defined as a joint convention where two parties meet together.
The President is the head of the State of India. He is the highest executive officer.

Complete answer:
The Parliament of India was founded on 26th January 1950 and it meets at Sansad Bhavan in New Delhi at least twice in a year. The Parliament is considered to be the supreme body of India. The members nominated or elected by the President in any of the houses of Parliament are known as the Members of Parliament. It is considered to be a bicameral legislature. The concurrence of both the houses, i.e. Lok Sabha and Rajya Sabha is required for passing any bill.
The creators of the Constitution predicted situations of deadlock between the Upper House, i.e. Rajya Sabha and the Lower House, i.e. Lok Sabha and this led to the formation of Joint Sittings of the Houses in order to break this deadlock. According to the Article 108 of Constitution of India the Joint Sitting of the Parliament is provided which is called by the President of India and presided by the Speaker. In case of absence of the Speaker it is presided over by the Deputy Speaker of the Lok Sabha and in his absence the Deputy Chairman of Rajya Sabha as the Chairman is not presided at any cost.

Note:Regarding the summoning it takes place in situations like:-
If a bill has been passed by one house but rejected by the other house
The houses have disagreed to the changes made in the bill.
When a period of six months has elapsed from the day of receiving the bill by the other house and is not passed by it.
