Network Devices Multiple Choice Question With Answer | Networking MCQs

Networking devices like repeaters, gateways, and switches are all used to build, extend, and connect different parts of a network.

Routers operate at the Network Layer (Layer 3) and use IP addresses to determine the best path for data packets.

A Gateway acts as a protocol converter, allowing communication between networks that use entirely different architectures and protocols.

A Repeater receives a signal and retransmits it at a higher level or higher power so that the signal can cover longer distances.

Bridges are used to connect two separate LAN segments that use the same protocol, effectively making them act as a single network.

A Switch is commonly used to connect multiple devices or LAN segments using the same protocol to facilitate communication within a network.

Repeaters work at the Physical Layer (Layer 1) as they only deal with bits and electrical/optical signals without looking at addresses.

A Switch is more secure than a Hub because it sends data only to the specific destination port (unicast) rather than broadcasting it to everyone.

Unlike a Hub which broadcasts data to all ports, a Switch uses MAC addresses to unicast messages directly to the intended recipient.

'Store & Backward' is not a standard switching technique; common methods include Store-and-Forward and Cut-Through.

Routers act as traffic controllers by managing data flow between different networks and choosing the most efficient paths.

Routers function at the Network Layer (Layer 3) of the OSI model to handle routing and logical addressing (IP).

Hubs operate in Half Duplex mode, meaning they can either send or receive data, but not both at the same time, leading to potential collisions.

Traditional standard Ethernet hubs typically operate at a speed of 10Mbps.

Gateways are specifically designed to bridge the gap between two networks that are built on entirely different technologies and protocols.

A Layer 3 switch combines the functionality of a switch and a router, allowing it to route data based on IP addresses.

Gateways are high-level devices that can operate across all seven layers of the OSI model to perform complex protocol translations.

In many network architectures, the gateway serves as the security checkpoint or Firewall for the internal network.

In a Star topology, all individual nodes are connected to a central device, which is typically a Hub or a Switch.

A Modem (Modulator-Demodulator) converts digital signals from a computer into analog signals for transmission over telephone lines, and vice versa.
