Cartridges are small containers that hold materials used in various devices. For example, in printers, cartridges contain ink or toner that helps produce text and images on paper. They are designed to be easily replaced when they run out, making it convenient for users to maintain their devices without needing to buy a whole new printer. In the world of gaming, cartridges refer to the physical media that store video games for consoles like the Nintendo Switch or Sega Genesis. These cartridges are inserted into the console, allowing players to enjoy their favorite games. Just like printer cartridges, they can be swapped out for different games, providing endless entertainment options.
