A simple icon, consisting of a series of links surrounded by a circle, is a common symbol for a connection or hyperlink. The lines of the icon are outlined in a dark black color on the background, with the addition of military elements of the Saudi national identity such as the Ghutra, Shamaa, and Saudi Bisht, to reflect the distinctive local character of Qassim University.
