VGA Cable: This is the most common cable used to connect your monitor (screen) to your computer and projector. If you are having issues with the display, check to make sure this cable is secure as being loose can often cause issues.
Ethernet: This is the cable that provides internet to your computer. If you find that you don't have an internet connection, check this on the computer and the wall to make sure it is secure. A loose cable can mean you will not connect to the network or the internet.
USB: This is a widely used cable for most peripherals such as keyboard or mouse. Sometimes unplugging and replugging into a different port, can fix a peripheral if the port had stopped working.
