Helpful context and quick facts
Computer networking is built on layered models (like OSI and TCP/IP) that standardize how data is packaged, addressed, transmitted, and received. A key milestone was the adoption of TCP/IP on ARPANET in 1983, which helped shape the modern Internet.
Tips for better scores
- Read the question for the layer or device being tested (link, network, transport, application)
- Watch for addressing clues like private IP ranges, masks, and default gateways
- Separate routing (between networks) from switching (within a LAN)
- Learn common ports and protocols (DNS, HTTP/S, SSH, DHCP)
- Use wrong answers to identify weak areas and retake quizzes to confirm improvement
