Networking Basics for Grade 14

What is network access?

• Network access is the ability to connect to a microwave.

• Network access is the ability to connect to a toaster.

• Network access is the ability to connect to a printer only.

• Network access is the ability to connect to and use resources on a network.

Explain the basics of networking.

• Networking is the practice of connecting computers and other devices to share resources and communicate with each other.

• Networking is a form of gardening

• Networking is a type of fishing technique

• Networking is the practice of knitting sweaters

What is IP addressing and why is it important in networking?

• IP addressing is crucial for identifying and communicating between devices on a network.

• IP addressing is irrelevant in modern networking

• IP addressing is only important for large networks

• IP addressing is used for securing network connections

Describe the structure of a network.

• A network consists of links but no nodes or protocols.

• A network is composed of only nodes without any links or protocols.

• A network is a single device connected to multiple protocols.

• A network consists of nodes (devices), links (connections between nodes), and protocols (rules for communication).

List and explain different networking devices.

• Routers, switches, hubs, modems, access points, firewalls

• Gateways

• Transceivers

• Repeaters

What is NAT (Network Address Translation) and what are the types of NAT?

• The types of NAT are Static NAT, Dynamic NAT, and Virtual NAT

• NAT stands for Network Access Terminal

• NAT is a method used to modify network address information in the IP header of packets while they are in transit across a traffic routing device. The main types of NAT are Static NAT, Dynamic NAT, and Port Address Translation (PAT).

• NAT is a method used to encrypt network traffic

Differentiate between L3 and L2 networks.

• L3 networks use IP addresses for routing, while L2 networks use MAC addresses for communication.

• L3 networks use IP addresses for communication, while L2 networks use MAC addresses for routing.

• L3 networks use MAC addresses for communication, while L2 networks use IP addresses for routing.

• L3 networks use MAC addresses for routing, while L2 networks use IP addresses for communication.

How does a router function in a network?

• A router functions by randomly selecting a path for data packets to travel.

• A router functions by storing all data packets it receives.

• A router functions by receiving data packets and determining the best path for them to reach their destination network.

• A router functions by sending data packets to all devices on the network.

What is a switch and how does it differ from a hub?

• A switch broadcasts data to all connected devices creating a single collision domain.

• A switch forwards data based on MAC addresses and creates separate collision domains, while a hub broadcasts data to all connected devices creating a single collision domain.

• A hub forwards data based on MAC addresses and creates separate collision domains.

• A switch and a hub perform the same functions and have no differences.

Explain the concept of subnetting in IP addressing.

• Subnetting helps in efficient utilization of IP addresses, reduces network congestion, and enhances overall network scalability.

• Subnetting has no impact on IP address management or network efficiency

• Subnetting causes network congestion and reduces IP address utilization

• Subnetting hinders network scalability and increases IP address wastage
