Word origin
The word 'queue' originates from the Latin word 'cauda', meaning 'tail'. This connection stems from the visual image of waiting people or items lined up. During the late Middle Ages, the term entered the English language, initially used to describe a line of people waiting for service. The pronunciation evolved over time, but the spelling remained relatively constant. As systems of organization developed, especially in governance and commerce, the term became more prevalent to describe both physical and abstract lines of items or tasks that are pending action. In computing, 'queue' became an essential term as programming and task management systems grew, referring to the ordering of processes for execution.
