Understanding Network Devices: Hubs, Switches, and Routers

The video tutorial explains the differences between hubs, switches, and routers in networking. Hubs are basic devices that broadcast data to all ports, while switches are more advanced, directing data to specific devices using MAC addresses. Routers are the most sophisticated, managing data between networks using IP addresses. The video also touches on additional router functions like DHCP and DNS services.

Which OSI model level does a hub operate on?

• First

• Second

• Third

• Fourth

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

• To route data to specific devices

• To encrypt data

• To broadcast data to all connected devices

• To filter data packets

Why are hubs considered less secure in modern networks?

• They require complex configurations

• They encrypt all data

• They are expensive

• They send data to all devices

What is a key difference between a hub and a switch?

• Switches operate on the first OSI level

• Hubs are more intelligent

• Hubs use IP addresses

• Switches send data to specific devices

What type of messages do switches broadcast to all ports?

• Private

• Encrypted

• Broadcast

• Unicast

How does a switch determine where to send data?

• By guessing

• By using MAC addresses

• By using IP addresses

• By user input

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

• To store data

• To encrypt data

• To broadcast data to all devices

• To connect different networks

Which device is capable of working with IP addresses?

• Hub

• Switch

• Router

• Modem

What additional functions can a router perform besides routing?

• Act as a DHCP server

• Encrypt data

• Broadcast data

• Store data

Which device is considered the most intelligent among hubs, switches, and routers?

• Hub

• Switch

• Router

• Modem
