Maya, Anika, and Ethan are working on a school project. They are trying to connect their computers to share and exchange information. What are they trying to create?

• They are trying to create a network, which is a term used to describe a group of animals living together in the wild.

• They are trying to create a network, which is a type of computer virus.

• They are trying to create a network, which is a collection of interconnected devices.

• They are trying to create a network, which is a group of people who are connected through social media.

Luna, Maya, and Anika are setting up a home network. What would be the purpose of a router in their network?

• The purpose of a router in their network would be to block data packets between their computer networks.

• The purpose of a router in their network would be to amplify data packets between their computer networks.

• The purpose of a router in their network would be to encrypt data packets between their computer networks.

• The purpose of a router in their network would be to forward data packets between their computer networks.

Aria, Olivia, and David are discussing the differences between LAN and WAN. What is the main difference between LAN and WAN?

• LAN is used for personal use while WAN is used for business purposes.

• LAN is a local network while WAN is a wide network.

• LAN is a wide network while WAN is a local network.

• LAN and WAN are the same thing.

Noah, Evelyn, and Oliver are discussing about their home networks. They are talking about IP addresses. What is an IP address?

• A password used to access a computer network.

• A type of computer virus.

• A software program that controls internet access.

• A unique numerical label assigned to each device connected to a computer network.

Michael is setting up a website for his school project. He wants to understand the role of DNS in a network. What does DNS do?

• DNS is responsible for encrypting network traffic.

• DNS translates domain names into IP addresses.

• DNS is a protocol used for file sharing in a network.

• DNS is used to authenticate users in a network.

Maya is working on a project that requires data transmission between two devices. She needs to choose between TCP and UDP protocols. What is the difference between TCP and UDP?

• TCP and UDP both provide reliable and ordered delivery of data packets.

• TCP guarantees reliable and ordered delivery of data packets, while UDP guarantees reliable delivery but not ordered delivery of data packets.

• TCP provides reliable and ordered delivery of data packets, while UDP does not guarantee reliable delivery or ordered delivery of data packets.

• TCP does not guarantee reliable or ordered delivery of data packets, while UDP guarantees reliable and ordered delivery of data packets.

Ethan, Daniel, and Emma are setting up a local network for their school's computer lab. Ethan mentions something about a subnet mask. What is a subnet mask in this context?

• A subnet mask is a 32-bit number used to divide an IP address into network and host addresses.

• A subnet mask is a security feature used to protect a network from unauthorized access.

• A subnet mask is a type of computer virus that can infect a network.

• A subnet mask is a hardware device used to connect multiple computers to a network.

Henry, Aria, and Elijah are setting up a network for their school's computer lab. Why would they want to install a firewall in their network?

• They would install a firewall to provide free internet access to all users in the school.

• They would install a firewall to block all incoming and outgoing traffic in the network.

• They would install a firewall to slow down the network speed in the computer lab.

• They would install a firewall to protect the school's network from unauthorized access and potential threats.

Charlotte, Avery, and Abigail are working on a school project about communication systems. They come across the term 'OSI model'. What is the OSI model in the context of their project?

• The OSI model is a conceptual framework that standardizes the functions of a communication system into seven different layers.

• The OSI model is a physical model that describes the layout of computer hardware components.

• The OSI model is a software program used for network monitoring and troubleshooting.

• The OSI model is a protocol used for encrypting and securing network communications.

Scarlett and James are setting up a network for their school's computer lab. They have a hub and a switch available. Aria, their classmate, asks them about the difference between a hub and a switch. How should they explain?

• They should tell Aria that a hub and a switch are the same thing.

• They should tell Aria that a hub is faster than a switch.

• They should tell Aria that a switch can only connect two devices at a time.

• They should tell Aria that a hub is a simple networking device that connects multiple devices in a network, while a switch is a more advanced networking device that connects multiple devices and intelligently routes network traffic.
