Adapters are devices that allow different types of equipment to connect and communicate with each other. For example, a USB to HDMI adapter enables a computer to send video signals to a television. Adapters can also convert power sources, such as changing a plug type to fit different electrical outlets. In technology, adapters are essential for compatibility between various devices. They can be found in many forms, including audio adapters that connect headphones to different ports, or network adapters that enable wireless connections. Overall, adapters help bridge gaps between different technologies, making them more versatile and user-friendly.
