Study Notes
TCP/IP and OSI Model Introduction
- The TCP/IP and OSI models are crucial for understanding network communication
- The OSI model, developed by the International Organization for Standardization (ISO), is a conceptual framework for standardizing network functionalities
- The OSI model consists of seven layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical
- The Application layer handles user applications
- The Presentation layer translates and encrypts data for the application layer
- The Session layer manages sessions and dialogues between applications
- The Transport layer ensures reliable data transfer
- The Network layer routes data, handles addressing, and forwards packets
- The Data Link layer manages node-to-node data transfer and error detection
- The Physical layer handles the physical connection and raw data transmission
- The OSI model serves as a universal guideline for network interoperability
- The TCP/IP model, developed by the U.S. Department of Defense (DoD), has four layers: Application, Transport, Internet, and Network Interface
- The Application layer in TCP/IP focuses on user interfaces and higher-level protocols
- The Transport layer manages end-to-end communication and data transfer
- The Internet layer handles routing and addressing of data packets
- The Network Interface layer focuses on network interfaces for data exchange
TCP Connection Observation using Wireshark
- A TCP (Transmission Control Protocol) connection, at the transport layer, follows steps:
- A three-way handshake (SYN-SYN-ACK-ACK) establishes the connection
- Data transmission occurs in segments, acknowledged by the receiving device
- Wireshark is a network protocol analyzer, used to capture, inspect, and analyze network traffic in real-time.
