Computer & Mobile Networks

Completed

Networking fundamentals for internet and mobile systems, including protocols, routing, wireless communication, and network troubleshooting.

What I Learned

I learned how data moves across networks, how protocols fit together across layers, and how mobile and wireless networking introduces additional design and performance considerations.

Key Concepts

Layered networking (TCP/IP approach)
Reliable vs unreliable transport
Network design, performance, and diagnostics

Key Topics

Network layers and protocol roles
IP addressing and routing
TCP and UDP
Wireless networking fundamentals
Mobile networking concepts
Network performance and troubleshooting

Practical Takeaways

Ability to explain end-to-end network communication more clearly
Better troubleshooting mindset for protocol and connectivity issues
Stronger foundation for packet analysis and cybersecurity work

Tools & Technologies
