Networking Devices: Hub, Switch, and Router APT

Front

What is the purpose of a hub in a network?

Back

A hub connects all network devices together on an internal network and rebroadcasts data packets to all ports.

Front

How does a hub handle data packets?

Back

A hub copies incoming data packets to all of its other ports, regardless of the intended recipient.

Front

What are the security concerns associated with using a hub?

Back

Hubs create unnecessary traffic on the network and expose all connected devices to data packets not intended for them.

Front

What is the main difference between a hub and a switch?

Back

A switch is intelligent and can learn the MAC addresses of connected devices, directing data packets only to the intended destination port.

Front

How does a switch manage data packets?

Back

A switch looks up the MAC address in its table and delivers the data packet only to the correct port.

Front

Why are switches preferred over hubs?

Back

Switches reduce unnecessary traffic on the network and improve security by directing data only to intended devices.

Front

What do hubs and switches use to exchange data?

Back

Hubs and switches are used to exchange data within a local area network (LAN).

Front

What is the role of a router in a network?

Back

A router routes or forwards data from one network to another based on IP addresses.

Front

How does a router determine where to send a data packet?

Back

A router inspects the data's IP address to determine if it is meant for its own network or another network.

Front

What happens to data packets not intended for a router's network?

Back

The router rejects data packets that are not meant for its own network.
