A voting system refers to a method by which people express their choice or opinion in an election, referendum, or poll. It is a process that allows individuals to make their voices heard and play a role in determining the outcome of an issue or decision. There are several different types of voting systems used around the world, including plurality/first-past-the-post, proportional representation, instant runoff voting, and more. The specific method chosen can have a significant impact on the results and outcomes of elections and other decision-making processes.
