Networking Devices and Their Functions

What is the primary function of a router?

• To store data packets for later use.

• To provide internet access to devices.

• To connect devices within a single network.

• To direct data packets between networks.

How does a switch differ from a hub?

• A switch forwards data to specific devices, while a hub broadcasts data to all devices.

• A switch operates at the physical layer, while a hub operates at the data link layer.

• A switch connects multiple networks, while a hub connects devices within a single network.

• A switch is used for wireless connections, while a hub is used for wired connections.

What role does a modem play in a network?

• A modem acts as a firewall to protect the network.

• A modem stores data for offline access.

• A modem amplifies the internet signal for better speed.

• A modem connects a network to the internet by converting digital data to analog signals and vice versa.

Define the purpose of a firewall in network security.

• To monitor employee internet usage for productivity.

• The purpose of a firewall in network security is to protect networks by filtering traffic and preventing unauthorized access.

• To provide a backup for network data storage.

• To enhance internet speed by optimizing data flow.

What is an access point used for in a wireless network?

• To increase the range of a wired network.

• To serve as a firewall for network security.

• To provide a direct internet connection to devices.

• An access point is used to connect wireless devices to a wired network.

What are the advantages of using a switch over a hub?

• Switches are less expensive than hubs.

• Hubs provide faster data transfer rates than switches.

• Hubs can connect more devices than switches.

• Switches are more efficient, reduce network collisions, provide better security, and allow for full-duplex communication compared to hubs.

How does a firewall protect a network?

• A firewall enhances network speed by increasing bandwidth.

• A firewall is used to store data securely on a server.

• A firewall allows all traffic to pass through without restrictions.

• A firewall protects a network by filtering traffic and blocking unauthorized access.

What is the main difference between a hub and a switch in terms of data handling?

• A hub and a switch both send data to all devices but at different speeds.

• A hub broadcasts data to all devices; a switch sends data only to the intended recipient.

• A hub filters data based on the type of device; a switch does not filter data.

• A hub sends data only to the intended recipient; a switch broadcasts data to all devices.

In what scenarios would you use a modem?

• To boost Wi-Fi signal strength.

• To create a local network without internet access.

• To connect to the internet via DSL, cable, or satellite.

• To connect a printer to a computer.

What is the significance of MAC addresses in a switch?

• MAC addresses are used to encrypt data in a switch.

• MAC addresses enable switches to direct data frames to the correct destination port.

• MAC addresses are only relevant for wireless networks.

• MAC addresses determine the speed of data transmission in a switch.
