Answer:
E
Step-by-step explanation:
The correct answer is E. repeater.
A repeater is a network device that strengthens and propagates a signal along a long communication line. It receives a signal on one side, amplifies it, and then sends it out on the other side. This allows the signal to travel longer distances without losing strength or becoming distorted. Repeaters are commonly used in network environments that require long-distance communication, such as in wide area networks (WANs).
A modem, on the other hand, is a device that converts digital data into a format that can be transmitted over a communication line, such as a telephone or cable line. It is commonly used to connect computers to the internet.
A gateway is a device that connects two networks with different protocols, allowing them to communicate with each other. It is commonly used to connect a local area network (LAN) to a wide area network (WAN), or to connect a LAN to the internet.
A node is a point of connection in a network, such as a computer, printer, or other device. It is a device that is connected to the network and can send and receive data.
A router is a device that forwards data packets between computer networks. It is used to connect multiple networks together, such as a LAN to the internet. It determines the best path for data to travel and forwards the data accordingly.
