Frequently Asked Questions

What networking models will I learn?

The course explains both the OSI and TCP/IP models and connects them to the link, network, transport, and application layers used in real networks.

Is previous networking experience required?

No. The lessons introduce core terminology, addressing, DHCP, and layered communication before later courses cover subnetting, routing, and configuration.

Why learn both OSI and TCP/IP?

The OSI model is useful for reasoning and troubleshooting, while the TCP/IP model more directly reflects the protocol suite used by modern networks.
