Bicameralism is a system of government in which the legislature is divided into two separate chambers or houses. This structure is designed to provide a system of checks and balances, ensuring that no single group has too much power. Many countries, including the United States and India, utilize bicameral legislatures to represent different interests and regions. Each chamber typically has distinct roles and responsibilities. For example, in the U.S. Congress, the two houses are the Senate and the House of Representatives. The Senate often represents states equally, while the House represents the population, allowing for diverse perspectives in the law-making process.
