TCP/IP Protocol Suite
TCP/IP is the foundational architecture powering all modern internet operations.
Definition for Exam:
TCP/IP (Transmission Control Protocol / Internet Protocol) is a suite of communication protocols that dictates how data is packetized, addressed, transmitted, routed, and received across a network.
The 4 Layers of TCP/IP:
- Application Layer: Interacts with software apps (Protocols: HTTP, FTP, SMTP, DNS).
- Transport Layer: Ensures end-to-end reliability and data sequencing (Protocols: TCP, UDP).
- Internet Layer: Handles logical IP addressing and routing (Protocol: IP).
- Network Access Layer: Connects software protocols to physical network hardware and cables.

2-Mark Questions
Q1. What is TCP/IP?
Answer: TCP/IP (Transmission Control Protocol/Internet Protocol) is the fundamental suite of networking protocols that governs how data is packetized, addressed, routed, and delivered across networks.
Q2. What are the specific functions of TCP and IP?
Answer: TCP breaks large data into smaller packets at the sending end and reliably reassembles them at the receiving end. IP handles logical addressing and routes those packets to the correct destination device.

3-Mark Questions
Q3. Briefly describe the 4 layers of the TCP/IP Architecture.
Answer:
- Application Layer: Provides network services directly to software applications (Protocols: HTTP, FTP, SMTP, DNS).
- Transport Layer: Manages end-to-end data sequencing, flow control, and reliability (Protocols: TCP, UDP).
- Internet Layer: Responsible for logical IP addressing and routing packets across different networks (Protocol: IP).
- Network Access Layer: Connects software layers to physical hardware media, framing data onto cables/signals.
