The act of communicating verbally via a telephone has evolved significantly. Traditional methods relied on circuit-switched networks. Contemporary telephone communication often utilizes digital networks, transmitting voice as data packets. This shift allows for features like Voice over Internet Protocol (VoIP), where the audio signal is converted into digital information and sent over the internet. For example, applications enabling voice communication over the internet transmit voice as data.
Understanding the underlying mechanisms of voice communication is essential in managing data consumption. This knowledge is beneficial for budgeting mobile data plans and optimizing network performance. The evolution of phone systems highlights the increasing integration of data networks in everyday communication. The historical transition from analog to digital systems has driven innovation and expanded communication possibilities.
