Study guide
This lab is about building and fixing real networks: identifying devices (LAN adapters, hubs, switches, routers), transmission media and tools (coaxial, UTP, crimping tool, connectors), preparing straight and cross cables, creating LAN topologies, configuring TCP/IP on Windows and Linux, sharing files and printers, designing class A, B and C networks with subnet plans, dynamic IP configuration, troubleshooting with ping and ipconfig, computing Hamming distance, installing an FTP server and client, configuring a proxy server and using network simulators. Learn to use ping first when something does not work; it narrows the problem quickly.
Why Computer Networks-I Laboratory Matters
Hands-on cabling, configuration and troubleshooting are the skills network and support engineers use every day, and they are a good first step toward certifications such as CCNA.
How to Prepare for Computer Networks-I Laboratory
- Practise making a straight and cross cable until the colour order is memorised.
- Use a simulator to test subnet designs before configuring real machines.
- Learn the basic troubleshooting steps: ping, ipconfig, then check cables and settings.
Computer Networks-I Laboratory: Frequently Asked Questions
What is done in the Computer Networks lab?
