Which of the following accurately describes the function of routers in a network?

Routers play a crucial role in networking by serving as devices that connect and manage multiple networks together. They facilitate data traffic between different networks, ensuring that information is correctly routed from one network to another. This includes directing data from a local area network (LAN) to a wide area network (WAN), such as the Internet, and determining the optimal path for data packets to travel based on various protocols and routing algorithms.

By managing the data flow between different networks, routers help to maintain efficient and secure communication by isolating and safeguarding segments of a network. This capability is essential for enabling various devices on separate networks to communicate without directly being connected to each other.

In contrast, amplifying signals to multiple devices involves different types of devices such as repeaters or switches, which enhance signal strength rather than direct network traffic. The conversion of analog signals to digital format is a function of modems or codecs, which handle signal translation rather than routing between networks. Finally, routers do not exclusively manage wireless devices; they can manage both wired and wireless devices simultaneously, allowing for a versatile networking environment.
