Introduction to LAN:

Key Topics:

LAN Topologies:

Understand the different physical layouts of local area networks (LANs).

Learn about star, bus, and ring topologies, their advantages and disadvantages.

Example: Visualize these topologies in the interactive lab within the task.

• Star Topology

Network Devices:

Explore the functions of key networking devices:

• Switches: Forward data packets directly to the intended recipient.
• Routers: Direct data between different networks.
• Hubs: Broadcast data to all connected devices.

Example: Understand how switches reduce network traffic compared to hubs in the lab.

• ARP Protocol:
• Learn how the Address Resolution Protocol (ARP) helps devices find each other's physical addresses (MAC addresses).
• Example: Investigate how ARP works in the interactive lab by capturing packets.
• DHCP Protocol:
• Discover the Dynamic Host Configuration Protocol (DHCP) and how it automates IP address assignment.
• Example: Understand the DHCP process by examining packet captures or configuring DHCP servers.

Subnetting:

• Understand how subnetting divides a large network into smaller, manageable subnets.
• Learn to calculate subnet masks and determine valid IP address ranges.
• Example: Practice subnetting exercises in the task or use online calculators.

Additional Learning Opportunities:

• OSI Model: Delve deeper into the seven layers of the Open Systems Interconnection (OSI) model, which describes how data is transmitted across networks.
• IP Addressing: Explore the basics of Internet Protocol (IP) addressing, including IPv4 and IPv6.
• Network Security: Investigate common security threats to LANs and learn how to protect against them.

Overall Learning Outcomes:

By completing the "Intro to LAN" room, you'll gain a foundational understanding of local area networks, their topologies, and essential protocols. You'll also develop practical skills in configuring and troubleshooting basic network components. This knowledge can serve as a stepping stone for further exploration of networking concepts and technologies.
