EVM stands for Electronic Voting Machine. It is a device that is used to record votes electronically without any manual interference. In India, EVMs were introduced in the 1990s and have been used in all the elections since then.

How does EVM work?

When a voter goes to vote, he or she is given a slip with the names of the candidates and their symbols. The voter has to press the button against the name of the candidate he or she wants to vote for. Once the button is pressed, the machine records the vote and displays a message saying 'Thank you for voting'. The vote is recorded electronically and the data is stored in the machine's memory.

Advantages of EVMs

- EVMs are easy to use and do not require any special skills or training.
- They are faster and more efficient than manual voting systems.
- EVMs are more accurate and reliable than manual voting systems as they eliminate the possibility of human error.
- They are tamper-proof and ensure the secrecy of the vote.

Disadvantages of EVMs

- EVMs are expensive to manufacture and maintain.
- They require a constant power supply and may malfunction if there is a power outage.
- EVMs require the use of batteries which can pose an environmental hazard.
- EVMs can be hacked or tampered with if they are not properly secured.

Why do we need Parliament? Explain in detail.

Parliament is the supreme law-making body in India. It is an essential institution of democracy and plays a crucial role in the functioning of the government. The primary functions of Parliament are:

1. Law-making: Parliament makes laws on various subjects that affect the lives of citizens. These laws are made through a democratic process involving debates and discussions in both the houses of Parliament.

2. Control over the government: Parliament exercises control over the government by holding it accountable for its actions. Members of Parliament can ask questions, raise issues of public importance, and demand explanations from the government.

3. Representation: Parliament represents the voice of the people and ensures that their interests are protected. Members of Parliament are elected representatives of the people and are expected to work in the best interests of their constituents.

4. Budgetary control: Parliament has the power to approve the budget and monitor the government's spending. It ensures that the government spends public money wisely and in accordance with the priorities of the country.

5. Constitutional amendments: Parliament has the power to amend the Constitution. This power ensures that the Constitution remains relevant and responsive to changing times.

In conclusion, Parliament is an essential institution of democracy and plays a vital role in the functioning of the government. It ensures that the government is accountable to the people and works in their best interests.
