How does the TCP/IP model differ from the OSI model?
- A.The TCP/IP model has 4 layers (Network Access, Internet, Transport, Application) compared to OSI's 7 layers - TCP/IP combines OSI's Physical and Data Link into Network Access, and merges Session, Presentation, and Application into a single Application layer. TCP/IP is the practical model used on the internet
- B.They are identical
- C.TCP/IP has more layers than OSI
- D.TCP/IP doesn't have a Transport layer
Why A is correct
TCP/IP model: Network Access (OSI 1+2), Internet (OSI 3), Transport (OSI 4), Application (OSI 5+6+7). TCP/IP is the practical implementation (actual internet protocols). OSI is the theoretical reference model. Both useful for understanding networking concepts.
