4.1.1-4.1.2 Network Devices (Scored)

What is the primary function of a router?

• The primary function of a router is to route data between different networks.

• To connect devices within the same network.

• To store data for backup purposes.

• To provide internet access to a single device.

How does a switch differ from a hub?

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

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

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

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

What does a Network Interface Card (NIC) do?

• A NIC is used for printing documents.

• A NIC manages the computer's power supply.

• A Network Interface Card (NIC) enables communication between a computer and a network.

• A NIC stores data for the computer.

What is the role of a NIC in a computer network?

• The role of a NIC in a computer network is to enable communication between the computer and the network.

• To store data temporarily for processing.

• To provide power to the computer.

• To manage the computer's hardware components.

What is a Media Access Control (MAC) address?

• A MAC address is a unique identifier for network interfaces.

• A MAC address is a software application for managing networks.

• A MAC address is a physical cable used for connections.

• A MAC address is a type of network protocol.

How is an IP address structured?

• An IP address is structured as either IPv4 (e.g., 192.168.1.1) or IPv6 (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).

• An IP address is always 32 bits long.

• An IP address consists of only letters.

• An IP address is a single number.

What is the purpose of data packets in networking?

• To encrypt data for security purposes.

• The purpose of data packets in networking is to encapsulate and transmit data efficiently across networks.

• To compress data for faster transmission.

• To store data permanently on a server.

What distinguishes a hub from a switch?

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

• A hub connects devices in a star topology; a switch connects them in a mesh topology.

• A hub operates at the network layer; a switch operates at the data link layer.

• A hub can filter data packets; a switch cannot filter data packets.

What is the function of a bridge in a network?

• To provide wireless connectivity

• To serve as a firewall for security

• The function of a bridge in a network is to connect and filter traffic between different network segments.

• To amplify signals in a network

How do routers manage data traffic?

• Routers manage data traffic by encrypting all packets before sending them.

• Routers manage data traffic by directing packets to their destinations using routing tables and implementing traffic management techniques.

• Routers manage data traffic by randomly dropping packets to reduce congestion.

• Routers manage data traffic by storing all data packets in a central server.
