Which model has five layers and was developed with protocols that grew up with Internet needs?

• A. OSI Model
• B. Internet Protocol Suite
• C. TCP/IP Model
• D. Hybrid Model

Answer: (C)

The concept being tested is the real-world, protocol-focused design of the Internet’s own architecture, the TCP/IP model (Internet Protocol Suite). This model grew from actual protocols that needed to interoperate across diverse networks as the Internet expanded. In practical diagrams it’s shown as five layers, reflecting how responsibilities are divided across the stack: a layer handling the hardware and network access, an Internet layer for addressing and routing, a Transport layer for end-to-end delivery, and an Application layer for user-facing protocols like HTTP, FTP, and email. Some descriptions split the hardware/Link portion further, which yields five layers in total, but the essence is that this model was built from working protocols that evolved with Internet needs. In contrast, OSI is a seven-layer framework created as a theoretical standard, not the actual Internet’s protocol suite. The Internet’s needs shaped the TCP/IP model, making it the correct reference for a five-layer depiction built around real-world Internet protocols.
