Which component serves as both a signal converter and connector in network communication?

The correct choice is the transceiver, as it functions both as a signal converter and as a connector in network communication. A transceiver is capable of transmitting and receiving information, which makes it essential for facilitating two-way communication. In the context of data networks, transceivers convert signals from one format to another, enabling different types of network media to communicate with each other. For example, in optical networks, a transceiver will convert electrical signals into optical signals and vice versa, allowing seamless communication over fiber optic cables.

This dual functionality of converting signals and serving as a connection point makes transceivers an integral part of modern networking equipment, where they ensure compatibility between different layers and types of communication technologies. As networks become increasingly complex, the ability to convert and transmit signals efficiently is increasingly important, highlighting the significance of transceivers in maintaining robust network communication.

In contrast, while repeaters amplify signals to extend transmission distances, they do not convert signals. Modulators change the form of signals for transmission over certain media, but they typically do not perform signaling for both directions (transmit and receive) within the same component. Aggregators combine multiple signals into one but do not serve the dual role of conversion and connection like a transceiver does.
