D.
Router

Explanation:
A repeater is a basic LAN connection device. It allows a network cabling system to
extend beyond its maximum allowed length and reduces
distortion by amplifying or regenerating network signals. Repeaters can also be used to connect
network segments composed of different
media, such as to connect a twisted pair cable segment to a fiber-optic cable segment. A repeater
works at the physical layer of the OSI
model.
Answer option A is incorrect. A hub is a device used to link computers in a network. It connects
computers that have a common architecture,
such as Ethernet, ARCnet, FDDI, or Token Ring. All hub-computer connections for a particular
network use the same type of cable, which can
be twisted-pair, coaxial, or fiber-optic. Hubs are generally used in star topology networks. Token
Ring hubs are also known as Multistation
Access Units (MSAUs). A hub works on the physical layer of the OSI model.
Answer option B is incorrect. A switch is a network connectivity device that brings media segments
together in a central location. It reads the
destination’s MAC address or hardware address from each incoming data packet and forwards the
data packet to its destination. This reduces
the network traffic. Switches operate at the data-link layer of the OSI model.

Answer option D is incorrect. Router is a device that routes data packets between computers in
different networks. It is used to connect
multiple networks, and it determines the path to be taken by each data packet to its destination
computer. Router maintains a routing table of
the available routes and their conditions. By using this information, along with distance and cost
algorithms, the router determines the best
path to be taken by the data packets to the destination computer. A router can connect dissimilar
networks, such as Ethernet, FDDI, and
Token Ring, and route data packets among them. Routers operate at the network layer (layer 3) of
the Open Systems Interconnection (OSI)
model.
