Final answer:
Voice over IP (VoIP) technology allows for transmission of voice communication over the Internet in digital format, leading to cheaper, faster, and better-quality data transmission and enabling technologies like free internet calling.
Step-by-step explanation:
The question pertains to Voice over IP (VoIP), which is a technology used for transmitting voice communication over the Internet or other packet-switched networks. VoIP is part of a broader trend in digital telecommunications where traditional analog signals, such as cell phone conversations and television voice and video images, are converted into a sequence of binary ones and zeros, thus enabling digital transmission.
This conversion into digital data increases the clarity of the transmission, especially when signals are weak, and allows for the application of computer algorithms that can compress data to enable more efficient transmission in each frequency range. With advances in technology, particularly the introduction of optical fibers with low loss and high bandwidth, telecommunications have seen improvements in terms of cheaper, faster, and better-quality data transmission. This supports spin-off technologies like free Internet-based calling and video calling, which leverage VoIP for cost-effective and high-quality communication.
