What is the main function of a network hub in a computer network?

• To send data to all connected devices

• To filter and forward data to specific devices

• To connect two different networks

• To provide wireless internet access

What is one main function of a router in a network?

• Connects different networks and sends data between them such as the internet.

• Only stores files for users

• Encrypts all network traffic

• Provides power to network devices

Why is a router important for network communication between devices and the internet?

• It manages the flow of data, directs traffic, and ensures devices can communicate with external networks.

• It only provides wireless signals to devices.

• It stores all the data on the network.

• It only connects printers to computers.

Which of the following devices would you use if you want every device in your network to receive the same data packet?

• Hub

• Switch

• Bridge

• Gateway

Explain one disadvantage of using a hub in a network compared to other network devices.

• Hubs are more secure than switches

• Hubs slow down the network by broadcasting data to all devices

• Hubs can only connect wireless devices

• Hubs increase the speed of data transfer

A network administrator needs to connect a local area network (LAN) to a wide area network (WAN). Which device should they use?

• Switch

• Bridge

• Gateway

• Hub

Which hardware component connects different types of networks together?

• Switch

• Bridge

• Gateway

• Router

Why are hubs considered inefficient in a network?

• They are expensive to purchase

• They slow down the network by sending data to all devices

• They only connect two devices at a time

• They require special software to operate

Which hardware component connects all your network devices together and sends data ONLY to the intended recipient?

• Switch

• Hub

• Repeater

• Modem

Why is it important for a network device to send data only to the intended recipient?

• To reduce network congestion and improve security

• To increase the number of devices on the network

• To allow all devices to receive the same data

• To make the network wireless
