Network Components

What is the function of a router in a network?

• To play music between computer networks.

• To cook data packets based on destination IP addresses.

• To forward data packets between computer networks based on destination IP addresses.

• To translate data packets into different languages.

Explain the role of a switch in a network.

• A switch in a network is a device that converts analog signals to digital signals.

• A switch in a network is a device that amplifies Wi-Fi signals to increase network speed.

• A switch in a network is a device that connects multiple devices within a local area network (LAN) and uses MAC addresses to forward data to the correct destination.

• A switch in a network is a device that blocks all incoming data traffic.

What is the purpose of a modem in networking?

• Modulate and demodulate digital data for transmission over analog communication lines.

• Regulate the flow of data within a network

• Encrypt and decrypt data for secure communication

• Translate data packets into binary code for transmission

Describe the function of a firewall in a network.

• Firewalls in a network are designed to create network congestion

• A firewall in a network is used to amplify network traffic

• The function of a firewall in a network is to monitor and control incoming and outgoing network traffic based on predetermined security rules.

• The function of a firewall in a network is to randomly block all network traffic

What is the difference between a hub and a switch?

• A hub broadcasts data to all devices, while a switch forwards data only to the intended recipient.

• A hub and a switch are interchangeable networking devices.

• A hub and a switch perform the same function in a network.

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

What is a network interface card (NIC) and why is it important?

• A network interface card (NIC) is a hardware component that allows a device to connect to a network. It is important because it enables communication between devices on the same network, facilitating data transfer and access to resources.

• A network interface card (NIC) is a software program that slows down network connections.

• A network interface card (NIC) is a type of monitor used to display network activity.

• A network interface card (NIC) is a type of printer that connects devices to a network.

What is a repeater and how does it work in a network?

• A repeater amplifies signals to reduce network latency.

• A repeater filters and blocks signals to improve network performance.

• A repeater encrypts data packets to secure network communication.

• A repeater regenerates and retransmits signals to extend the reach of a network.

Explain the concept of a gateway in networking.

• A gateway in networking is a device that connects two different networks, serving as an entry and exit point for data. It acts as a bridge between networks with different protocols, allowing communication between them.

• A gateway is a software application used for editing network settings

• A gateway is a type of computer virus that spreads through networks

• A gateway is a physical barrier that blocks network traffic

What is the significance of a patch panel in network infrastructure?

• A patch panel is only necessary for small-scale networks

• A patch panel is primarily for decorative purposes in network infrastructure

• A patch panel is used to regulate network speed

• A patch panel simplifies cable management and facilitates easier network troubleshooting and reconfiguration.

Describe the role of a network cable in connecting devices.

• A network cable wirelessly connects devices

• A network cable is used for charging devices

• A network cable is only used for decoration

• A network cable physically connects devices to a network, allowing data to be transmitted between them.
