Study Notes
TCP and UDP
- TCP (Transmission Control Protocol) is a connection-oriented protocol. A connection is established between the sender and receiver before data transmission.
- UDP (User Datagram Protocol) is a connectionless protocol. No connection is established before data transmission.
- TCP provides reliable data transfer, ensuring all data is transmitted correctly, completely, and in the correct order.
- TCP employs acknowledgments and retransmissions to guarantee data integrity.
- UDP offers faster data transmission than TCP, lacking the overhead of connection establishment and error checking.
- TCP is suitable for applications requiring reliable transfer, like file transfers and web browsing.
- UDP is preferable for applications needing speed, even with potential data loss, such as video streaming and online gaming.
- TCP incorporates flow control to regulate transmission rate, preventing sender overload of the receiver.
- UDP lacks flow control.
OSI Model
- The OSI (Open Systems Interconnection) model is a conceptual framework defining networking system functions.
- It comprises seven layers, each with distinct responsibilities.
- Layers include:
- Physical Layer: Transmits raw bit streams over the physical medium.
- Data Link Layer: Encapsulates bits into frames, controlling physical medium access.
- Network Layer: Routes packets across networks.
- Transport Layer: Provides reliable or unreliable data delivery between applications.
- Session Layer: Establishes, manages, and terminates communication sessions.
- Presentation Layer: Translates data formats between applications.
- Application Layer: Provides network services to applications (e.g., email, web browsing).
- Layers interact in a structured manner.
- Each layer adds its header to data before passing it down.
- Headers are removed at each receiving step.
TCP/IP Model
- TCP/IP (Transmission Control Protocol/Internet Protocol) model underpins the internet.
- It's simpler than the OSI model, with only four layers.
- Layers consist of:
- Network Access Layer: Corresponds to OSI's physical and data link layers, handling physical data transmission.
- Internet Layer: Corresponds to OSI's network layer, managing packet routing. IP is central in this layer.
- Transport Layer: Matches OSI's transport layer, providing reliable or unreliable data delivery. TCP and UDP operate here.
- Application Layer: Corresponds to OSI's session, presentation, and application layers, providing network services to applications.
Comparison of TCP/IP and OSI Models
- Both models are hierarchical, employing layered structures for networking.
- The TCP/IP model is simpler and more practical, reflecting real-world network design better.
- The OSI model is more theoretical, serving as a conceptual framework.
- TCP/IP is used in practical networking; the OSI model is primarily a reference.
- Modern networks predominantly use TCP/IP protocols.
- While more comprehensive, the OSI model hasn't achieved the same standardisation as TCP/IP.
