Hubs, Switches and Routers

What is the primary function of a hub in a network?

• To intelligently direct data packets to the correct destination

• To connect all network devices together on an internal network

• To route data packets based on their IP addresses

• To store data for network devices

Why is a hub considered not intelligent?

• Because it can store MAC addresses

• Because it filters data to the correct port

• Because it rebroadcasts data to all ports regardless of the destination

• Because it can route data packets based on IP addresses

What is a key feature that differentiates a switch from a hub?

• A switch rebroadcasts data to all connected devices

• A switch routes data based on IP addresses

• A switch learns and stores the MAC addresses of connected devices

• A switch cannot connect multiple network devices

How does a switch handle data packets compared to a hub?

• It requires manual configuration for each data packet

• It sends data packets only to the device that is the intended recipient

• It sends data packets to all connected devices

• It discards all incoming data packets

What is the main role of a router in a network?

• To store MAC addresses of devices

• To route data packets between different networks based on IP addresses

• To connect internal network devices

• To rebroadcast data packets to all ports

Why can't hubs and switches route data outside their own network?

• Because they do not have the capability to read or interpret IP addresses

• Because they can only connect to devices within the same network

• Both B and C are correct

• Because they only operate on physical addresses or MAC addresses

What happens when a router receives a data packet not meant for its own network?

• It forwards the data packet to another network

• It discards the data packet

• It stores the data packet for later processing

• It sends the data packet to all connected devices

How do routers on the internet interact with each other?

• By storing MAC addresses of all devices across networks

• By rebroadcasting data packets to every connected network

• By exchanging data packets based on their MAC addresses

• By forwarding data packets to the correct network based on IP addresses

What is the significance of the color-coded data packets in the explanation?

• To represent different IP addresses intended for specific networks

• To indicate the speed of data transmission

• To differentiate between data packets sent to hubs and switches

• To show the level of security of data packets

What is the primary advantage of using switches over hubs in a network?

• Switches can connect more devices than hubs

• Switches can operate without electricity

• Switches reduce unnecessary network traffic by directing data packets only to the intended recipient

• Switches are cheaper than hubs
