What technology allows different network segments to communicate with each other?

The correct answer is internetworking, which refers to the practice of connecting different networks to enable communication between them. This technology facilitates the seamless exchange of data and resources across distinct network segments, regardless of differences in protocols or architectures. By utilizing devices such as routers and switches, internetworking creates a cohesive environment that supports interaction among diverse types of networks, such as local area networks (LANs), wide area networks (WANs), and even the internet.

Internetworking leverages standards such as the Internet Protocol (IP) to ensure that data packets can be routed effectively between various network segments, overcoming potential barriers associated with dissimilar systems. This fundamental capability is crucial for modern networking, where organizations often maintain various kinds of networks for different functions.

The other options represent important network security and communication technologies, yet they do not primarily focus on enabling communication among distinct network segments. Intrusion Prevention Systems (IPS) are designed to monitor and protect networks from threats but do not facilitate communication. Virtual Private Networks (VPN) create secure and encrypted connections over the internet, primarily for remote access, rather than for inter-segment communication. Network Address Translation (NAT) is used to modify IP address information in packet headers while in transit, primarily for the purpose
