← Back to Syllabus

These practicals are made for doing in class. Students should look, touch, run commands, draw, discuss and show what they learned.

Do first

1. Look at a router, switch, modem, cable and connector.
2. Say the name of each item and what it does.
3. Run one simple network command such as ping or ipconfig.
4. Draw a small network map on paper.

Do in class

1. Watch a short visual explanation of how devices connect.
2. Handle the networking devices and point to the ports and cables.
3. Compare wired and wireless connection by using real examples.
4. Work in pairs to check IP address, default gateway and a ping result.

Evaluation

1. Quizzes and short tests on devices, cables and protocols.
2. Peer evaluation during group work and demonstrations.
3. Presentation of a small network model or practical report.

Step-by-step tasks practice by doing

Task 1 — Identify devices & cables

1. Gather a set of cables (CAT5/6, fiber patch) and devices (router, switch, modem).
2. Label each cable and connector; identify RJ45 pins and fiber connectors.
3. Verify: take a photo and list each item's purpose.

Task 2 — Check IP & Default Gateway

1. On Windows: open Command Prompt and run ipconfig /all. On macOS/Linux ifconfig or ip addr.
2. Note your IPv4 address, subnet mask and default gateway.
3. Verify: ping the gateway.

ping <gateway-ip>

Task 3 — Basic network tools

1. Use ping to ping 8.8.8.8 and record latency.
2. Use tracert (Windows) or traceroute (macOS/Linux) to trace route to example.com.
3. Use nslookup to resolve domain names.

Task 4 — Create a small LAN

1. Connect two computers to a switch; set static IPs in same subnet.
2. From one, ping the other and transfer a small file via simple HTTP or shared folder.
3. Verify: successful ping and file transfer.

Task 5 — RJ45 crimping demo

1. Demonstrate how to strip, arrange wires (T568B) and crimp an RJ45 plug.
2. Test using a cable tester or by connecting.

3

Student output what to submit

Log

1. Write the device names and one line about each.
2. Add screenshots or a photo of the activity.

Presentation

1. Say what you did in the activity.
2. Tell one thing you learned.
