Hardware Devices in Computer Networking

A device connecting multiple LANs to a larger LAN.

Connecting different LAN topologies or segments; improving bandwidth by creating separate collision domains.

OSI model's data link layer; a two-switch level part in network architecture.

A network device connecting dissimilar networks and converting protocols for seamless communication.

The act of bridging different sections of network.

Network security managed by a gateway, which filters and analyzes data packets.

A gateway's role in translating different network languages or protocols.

Careful planning is needed when adding switches to prevent network loops or exceeding device/port limits.

Connects multiple devices on a network, allowing them to communicate.

Data can flow in only one direction at a time.

Connects devices on a local area network (LAN) to enable communication.

Operates at Layer 2 (Data Link Layer) of the OSI model.

Maintains a table of MAC addresses of connected devices, mapping them to ports.

Forwards data packets only to the intended recipient's port.

Increases network efficiency, reduces collisions, and offers scalability.

Can be expensive, limited distance for connections, and single point of failure.

A networking device that connects multiple networks and directs data packets between them. It determines the best path for forwarding data to its destination, enabling communication between devices on different networks.

Routers examine data packets and use their routing tables to decide the best path to send them. They connect different networks, like an office's HR and IT departments, and can also connect to the internet.

A simple networking device that connects multiple devices in the network. It broadcasts data to all connected devices.

It acts as a central connection point for devices on a network, but unlike a switch, it doesn't filter data. This means any data sent through the hub is received by all connected devices.

Unlike a switch, which filters and sends data only to its intended receiver, a hub does not filter data and broadcasts it to all connected devices.

A hub operates at the Physical Layer of the OSI model, offering a simple way to connect multiple devices.

Hubs are inexpensive and simple to use, making them suitable for basic networking tasks and small-scale networks.

A network topology where devices are connected to a central hub. It's simple to set up and manage, but the central hub can be a single point of failure.
