What is API?

Imagine you're at a restaurant and you want to order your favorite burger. You can't just walk into the kitchen and start making it yourself because that's not how it works!

Instead, you give your order to the waiter, and they take it to the kitchen staff. They then prepare your burger according to your request, and the waiter brings it back to you.

In this scenario, the waiter is like an API (Application Programming Interface). Here's how:

- You (the customer) are like a computer program or app that wants to get something done (like ordering a burger).
- The kitchen (the restaurant's system) has the ability to make burgers, but you can't directly access the kitchen.
- The waiter (the API) acts as an intermediary between you and the kitchen. You tell the waiter what you want, and they communicate your request to the kitchen staff.
- The kitchen staff then prepares your burger according to your request, and the waiter brings it back to you.

In the same way, an API allows different computer programs or apps to communicate with each other and exchange information. It's like a messenger that helps different systems work together!

So, just like how you can't walk into the kitchen and start making your own burger, a computer program can't directly access another system's data or functions without an API. The API helps facilitate the communication and exchange of information between different systems.

The United Nations (UN) is an international organization founded on October 24, 1945, with the primary goal of promoting peace, security, and cooperation among its member states ¹. The UN replaced the League of Nations and was established after World War II to prevent future wars and foster friendly relations among nations.

*History*
The UN's formation was a response to the devastation of World War II, with the signing of the UN Charter by 51 countries in San Francisco on June 26, 1945. The first session of the UN General Assembly was convened on January 10, 1946, in London

*6 Main Organs*

1. *General Assembly (GA)*: The main policy-making and representative body, comprising all 193 member states. It meets annually in September and makes key decisions, including appointing the Secretary-General and approving the UN budget
2. *Security Council (SC)*: Responsible for maintaining international peace and security, with 15 members, including 5 permanent members (China, France, Russia, the UK, and the US)
3. *Economic and Social Council (ECOSOC)*: Coordinates economic and social work, promoting higher standards of living, full employment, and economic and social progress. It has 54 members elected by the General Assembly for three-year terms
4. *International Court of Justice (ICJ)*: The primary judicial organ, settling legal disputes submitted by states and providing advisory opinions on legal questions. It consists of 15 judges elected by the General Assembly and Security Council for nine-year terms
5. *Secretariat*: The administrative organ, headed by the Secretary-General, who is appointed by the General Assembly on the recommendation of the Security Council. The Secretariat carries out the day-to-day work of the UN
6. *Trusteeship Council*: Administers trust territories, which are territories not yet self-governing. However, since the last Trust Territory became independent in 1994, the Council has suspended operations
