Centralized control of internet layers threatens privacy. The TCP/IP model reminds us why decentralized protocols must stay open.

How each layer enables (or risks) freedom (e.g., ISP throttling at Network Access).

The OSI Model Explained: Key Layers in Computer Networking

Introduction The Open Systems Interconnection (OSI) model, created by the International...

DEV Community

In the world of networks where data flow, wired and wireless teleport to different destinations.

The OSI Model, its layers bestow.
From physical to application, each one unrolls, A framework of communication, enjoining our hearts.

👉 Layer one,
The foundation, physical and raw,
Bits and bytes, in cables they defect.
Electric impulses, signals they carry,
Setting the stage for connections to engage.

👉 Layer two,
Data link, where frames find their way, MAC addresses guide like stars in the candy way. Error detection, a vigilant check, Ensuring integrity, a safety net.

👉Layer three,
Network with routers and routes,
IP addresses secure, like winding routes.
Packet forwarding, across networks vast,
Routing protocols, a quest to broadcast.

👉 Layer four,
Transport where connections thrive,
TCP and UDP their protocols drive.
Reliable delivery for bytes to travel,
Seamless streams no matter the unravel.

👉 Layer five,
Session, a bridge in the mist,
Establishing and managing connections, it persists.

Allowing sessions, strings of communication,
controlled and organized, like a symphony's creation.

👉 Layer six,
Presentation, a translator supreme,
Encodes and decodes, the data's dream.
Encryption and compression, its key affair,
Translating information, beyond compare.

👉 Layer seven,
Application, where humans flex,
Web browsers and emails become our guide. Interacting with services, like a dance, Empowering users with a fruitful enhance.

The OSI Model, a harmonious blend,
Layer upon layer, its message to send.
From physical to application, it unfolds,
A network's grand tapestry, where wonders behold.

The legend all the tech geeks struggle with and the attacker's hideout.
