The telephone is an effective and commonly used medium for oral communication due to the following factors:
1. Immediacy: This technology facilitates instantaneous interaction, allowing individuals like Rahul to issue prompt directives to his staff.
2. Lucidity and Clarification: Spoken instructions minimize ambiguity by enabling immediate question resolution.
3. Speed: It offers a time-saving alternative to written formats such as electronic mail or memoranda.
For example, Rahul can rapidly converse about project advancements and address challenges with his team via telephone.
