Directional refers to something that indicates or shows a specific direction or path. This term is often used in navigation, where directional signs help guide people to their destinations. For example, a compass provides directional information by pointing towards the magnetic north, helping travelers orient themselves. In technology, directional can describe devices that focus their signals in a specific direction. For instance, a directional antenna is designed to transmit or receive signals more effectively in a particular direction, improving communication range and quality. This concept is essential in various fields, including telecommunications and broadcasting.
