1b Network Devices - Repeater, Hub, Bridge, Switch & Router Flashcards
(16 cards)
What problem does a Repeater solve?
It fixes data decay over long distances by regenerating the signal.
What is a Hub and what does it do?
A multi-port repeater that sends all traffic to all connected devices.
What’s the downside of using a Hub?
It broadcasts all traffic to every device on the network.
What is a Bridge used for?
To connect two hubs and learn which devices are on each side.
A Switch is the love-child of…
A Hubs and a Bridge; with multiple smart ports.
What is the role of a Router?
To connect different networks and route data between them.
What is a Routing Table?
A list of known networks and the best routes to reach them.
What’s the difference between Routing and Switching?
Routing = between networks; Switching = within a network.
What is the primary function of a Repeater?
Fixes data decay over long distances by regenerating the signal.
How does a Bridge function in a network?
Connects two hubs and learns which devices are on which side.
What is a Switch?
A smart combination of Hubs and Bridges that learns where devices are and sends data only to the correct port.
What is the role of a Router?
Connects separate networks and uses a Routing Table to decide where data should go.
Fill in the blank: A Router has a _______ IP in each network, acting as the ‘exit door’ for traffic.
Gateway
What do Routers store to facilitate communication?
Routes in a Routing Table.
True or False: The Internet is made up of many Routers passing data along.
True
What is the purpose of a Gateway in networking?
A host’s way out of their network.
