Networks Challenge

What is a network?

• A network is a collection of interconnected devices.

• A network is a physical barrier between devices.

• A network is a single device.

• A network is a group of unrelated devices.

Explain the difference between LAN and WAN.

• LAN connects devices in a limited area, while WAN connects devices over a large geographical area.

• LAN and WAN are the same thing

• LAN is used for wireless connections, while WAN is used for wired connections

• LAN is faster than WAN

What is a router used for in a network?

• A router is used to play music in a network.

• A router is used to water plants in a network.

• A router is used to forward data packets between computer networks.

• A router is used to cook food in a network.

Define the term 'bandwidth' in relation to networks.

• Amount of memory storage on a computer

• Number of devices connected to a network

• Minimum data transfer rate of a network

• Maximum data transfer rate of a network or internet connection

What is the purpose of a firewall in a network?

• To monitor and control incoming and outgoing network traffic based on security rules.

• To bake cookies

• To play music

• To water the plants

What is a MAC address and how is it used in networking?

• A MAC address is a unique identifier assigned to network interfaces for communications on a network.

• A MAC address is a software application used to browse the internet.

• A MAC address is a type of computer virus used to infect networks.

• A MAC address is a physical address used to send letters in networking.

What is the function of an IP address?

• To play music on a device

• To uniquely identify a device on a network and enable communication between devices.

• To cook a meal

• To predict the weather

Explain the concept of packet switching.

• Packet switching requires a dedicated point-to-point connection for data transmission.

• Packet switching does not involve addressing packets with destination information.

• Packet switching involves sending data in a continuous stream without any division.

• Packet switching involves breaking down data into packets, each with a destination address, sending them independently over the network, and reassembling them at the destination.

What is a DNS server and what is its role in networking?

• A DNS server is a type of hardware used to connect multiple computers in a network.

• A DNS server is responsible for managing email communication between devices.

• A DNS server is used to store photos and videos on a computer network.

• A DNS server translates domain names into IP addresses for internet communication.

Differentiate between a hub and a switch in a network.

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

• A hub operates at Layer 3 of the OSI model, while a switch operates at Layer 2.

• A hub has multiple collision domains, while a switch has a single broadcast domain.

• A hub filters data based on MAC addresses, while a switch filters based on IP addresses.
