Grade 12 Computer Networking Quiz

Why are computer networks important in today's world?

• Computer networks are important only for accessing entertainment

• Computer networks are important in today's world because they allow for communication, sharing of resources, and access to information on a global scale.

• Computer networks are only important for local communication

• Computer networks are not important in today's world

What are the different types of computer networks?

• Computer networks are categorized as Happy, Sad, and Angry

• Types of computer networks include AAN (Alien Area Network), BAN (Banana Area Network), and PAN (Penguin Area Network)

• The different types of computer networks include LAN (Local Area Network), WAN (Wide Area Network), WLAN (Wireless Local Area Network), MAN (Metropolitan Area Network), and CAN (Campus Area Network).

• The different types of computer networks are Red, Blue, and Green

Explain the concept of networking protocols.

• Networking protocols are physical cables used to connect devices on a network.

• Networking protocols are a set of rules and conventions that govern the communication between devices on a network. They define how data is transmitted, received, and processed, ensuring that devices can understand and interpret the information being exchanged.

• Networking protocols are only necessary for small networks, not for large-scale networks.

• Networking protocols are only used for wireless communication, not for wired networks.

What is the difference between LAN and WAN?

• LAN is a wireless network, while WAN is a wired network.

• LAN is a network that connects computers and devices within a limited area, such as a home, office, or building, while WAN is a network that connects computers and devices over a large geographical area, such as across cities, countries, or continents.

• LAN is a network that connects computers and devices over a large geographical area, while WAN is a network that connects computers and devices within a limited area.

• LAN and WAN are the same and can be used interchangeably.

What are the advantages and disadvantages of using a wireless network?

• Advantages include mobility, easy installation, and flexibility. Disadvantages include potential security risks, interference, and limited range.

• Advantages include limited mobility, complicated installation, and lack of flexibility.

• Disadvantages include no security risks, no interference, and unlimited range.

• Advantages include high cost, slow speed, and difficult setup.

What is the role of routers in a computer network?

• Routers are responsible for forwarding data packets between computer networks, making decisions about the best path for the packets to travel, and ensuring that the packets reach their intended destination.

• Routers are used to store data on the network

• Routers are only used for connecting devices to the internet

• Routers are responsible for creating new computer networks

How does the internet work and what are its key components?

• The key components of the internet are telephones and fax machines

• The internet is controlled by a single giant computer in a secret underground bunker

• The internet works through a global network of interconnected computers and servers. Its key components include routers, switches, and protocols such as TCP/IP.

• The internet is powered by magic and unicorns
