Explanation

Expansion bus is a collection of wires and protocols used for the expansion of a computer. It connects expansion cards such as network interface card, video card, etc., to system bus. Expansion cards connect to the expansion bus through the expansion slot. Answer option D is incorrect. Fiber optic cable is made of light-conducting glass or plastic fibers. Answer option C is incorrect. Expansion bus is not a network connectivity device. It does not translate different communication protocols and is not used to connect dissimilar networks. FactWhat is a gateway? Gateway is a network interconnectivity device that translates different communication protocols and is used to connect dissimilar network technologies. It provides greater functionality than a router or bridge because a gateway functions both as a translator and a router. Gateways are slower than bridges and routers. Gateway is an application layer device.
