Final answer:
An IP network transmits both voice and computer data using technologies like optical fiber and wireless systems such as satellite and microwave, enabling efficient and high-quality communication.
Step-by-step explanation:
The network that transmits both voice and computer data, effectively replacing traditional voice networks, is known as an IP (Internet Protocol) network. This technology includes advancements such as extensive optical fiber infrastructures and wireless technologies like satellites and microwave transmission. Optical fiber systems are advantageous because of their low loss, high bandwidth, and reduced crosstalk, allowing for long-distance, cheaper, faster, and better-quality data transmission. Additionally, cell phone conversations, television voice and video images, and computer data are all transmitted as digital binary sequences, facilitating the use of compression algorithms to transmit more data efficiently. The emergence of the Internet and subsequent spin-off technologies like free Internet-based calling and video calling, have dramatically improved and expanded communication capabilities, offering services that were once expensive and low quality.
