Year 12 Computer Science - Network Protocols
9th October 2025
On Friday last week, Mr. Harrison Mwangi, our Network Administrator and in-house expert, visited the Year 12 Computer Science class to share his expertise on data transmission and network protocols. His depth of knowledge and professional experience brought the topic to life, offering students a fascinating real-world perspective on this important field of Computing.
During the session, Mr. Mwangi outlined the basics of IPv4, the most widely used Internet Protocol that assigns unique numerical addresses to devices so they can communicate across networks. He also explained subnetting, a technique used to divide larger networks into smaller, more efficient segments, helping to improve performance and security.
Students learned about the vital role of routers, which direct data packets between different networks and ensure that information reaches its correct destination. Mr. Mwangi also discussed the rise of IPv6, the next generation of Internet Protocol designed to replace IPv4, offering a vastly larger address space and improved efficiency for the ever-growing number of connected devices.
The talk helped students connect theoretical knowledge with practical applications, deepening their understanding of how data moves seamlessly across global networks.
A big thankyou to Mr. Harrison Mwangi
