Motherboards contain many different expansion slots including USB or universal serial bus, HDMI or high-definition media input, VGA or video graphic array, RJ45 or Ethernet, SATA or serial AT attachment, and more. The USB expansion slots can be used for peripherals such as keyboards, mice, and headphones as well as for storage like flash drives or charging another device. Another thing to consider when using USB is that three different generations of USB will also have different connectors and are capable of different speeds. Users can also use different expansion slots for video such as HDMI, VGA, and DVI which connect to a monitor or projector to display the screen. SATA expansion slots are also used to connect external hard drives for more passive storage while the onboard NVME M.2 slots are used for quicker storage. Just like USB, SATA also has three different generations which get faster the higher the number.
