The OSI model, or Open Systems Interconnection model, is a conceptual framework that standardizes network communication. It divides the process into seven layers, each handling specific tasks like data presentation, routing, and physical connections. This model helps in understanding and designing networks effectively.


📱 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻: Handles user interfaces, application services, and high-level protocols.

🎁 𝗣𝗿𝗲𝘀𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻: Deals with data translation, encryption, and compression.

🤝 𝗦𝗲𝘀𝘀𝗶𝗼𝗻: Manages sessions or connections between applications.

🚚 𝗧𝗿𝗮𝗻𝘀𝗽𝗼𝗿𝘁: Ensures reliable end-to-end communication. Similar to the transport layer in TCP/IP.

🌐 𝗡𝗲𝘁𝘄𝗼𝗿𝗸: Focuses on logical addressing and routing of packets.

🔗 𝗗𝗮𝘁𝗮 𝗟𝗶𝗻𝗸: Manages access to the physical medium and error detection.

🔌 𝗣𝗵𝘆𝘀𝗶𝗰𝗮𝗹: Concerned with the physical medium like cables, switches, and connectors.

TCP/IP, short for Transmission Control Protocol/Internet Protocol, is a set of rules governing how data is sent and received over networks. It's the foundation of Internet communication, ensuring reliable data delivery (TCP) and guiding data packets to their destinations (IP).


📱 𝗔𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻: This layer is responsible for high-level protocols like HTTP, FTP, SMTP, etc.

🚚 𝗧𝗿𝗮𝗻𝘀𝗽𝗼𝗿𝘁: Manages end-to-end communication, ensuring data delivery and reliability. TCP and UDP protocols operate at this layer.

🌐 𝗜𝗻𝘁𝗲𝗿𝗻𝗲𝘁: Focuses on routing and forwarding packets across different networks. IP (Internet Protocol) is the primary protocol at this layer.

🔗 𝗟𝗶𝗻𝗸: Deals with the physical connections, addressing, and access to the medium (Ethernet, Wi-Fi, etc.).

1: 🌐 The TCP/IP model is more commonly used in practical applications and is closely tied to the functioning of the modern internet.
2: 🔬 The OSI model is more of a theoretical standard and is often used for educational purposes and as a reference point for understanding network concepts.
3: Both models provide a structured way to understand and discuss networking concepts, but TCP/IP is the dominant model in terms of real-world implementation. 🌐🔬.
