What is the difference between an airport gate and a terminal, and how do they function together to facilitate the smooth flow of passengers and flights?

An airport gate is where passengers board and disembark from a specific flight, while a terminal is the entire building where passengers check-in, go through security, and access various gates. Gates and terminals work together by providing designated areas for different flights to operate efficiently, ensuring passengers can move smoothly between check-in, security, and their flights.
