NET-01Network SystemsInteractive simulation
Network Topology & Packet Flow
Follow how information travels from an end device, through switching and routing infrastructure, to a destination server.
- Packet
- Frame
- IP / MAC
- Network path
NET-02Network SystemsInteractive simulation
ARP & MAC Address Resolution
See how a device discovers the MAC address behind a local IP destination, and how the resulting Ethernet frame moves across the LAN.
- ARP request
- ARP reply
- MAC table
NET-03Network SystemsInteractive simulation
IP Routing & Packet Forwarding
Understand how routers examine destination information and forward packets between different networks.
- Routing table
- Next hop
- Subnets
- TTL
NET-04Network SystemsInteractive simulation
TCP vs UDP Communication
Compare the transport-layer behaviour of TCP and UDP side by side across the same path.
- TCP
- UDP
- Transport layer
- Ports
NET-05Network SystemsInteractive simulation
DHCP & DNS Network Services
Understand how a device obtains its network configuration and how domain names are resolved to addresses.
- DHCP
- DNS
- Name resolution
- Gateway
NET-06Network SystemsInteractive simulation
VLAN & Network Segmentation
Understand how one physical switch infrastructure is logically separated into VLANs, and how traffic between segments is handled.
- VLAN
- Access port
- Trunk
- Broadcast domain
