Network Mega Labs

Master the syllabus safely avoiding examiner traps through interactive simulation.

Network Performance Sandbox

Theory: 1.3.1 Factors

Download a 1000 MB file. Adjust the factors (Bandwidth, Users, Interference) to see how they impact the true speed available per device.

Connection Medium (Base Bandwidth)

Active Users / Devices: 1

More devices split the available bandwidth.

Physical Interference

Effective Bottleneck Speed

1000 Mbps

Calculated natively removing protocol overhead for simplicity.

DNS Phonebook Visualiser

Theory: 1.3.1 Internet

Examiner Trap Override: Examiners hate when you say the DNS "searches the internet". Let's prove it doesn't search. It simply acts as a static translation directory.
