How do user applications, data encryption, and active sessions work at the top of the OSI model? Through the final three layers.
Here are the key points:

🔹 1. Layer 5 - Session Layer
Establishes, maintains, and terminates communication "sessions" between devices (e.g., managing your active login session on a banking app).
🔹 2. Layer 6 - Presentation Layer
Acts as a translator and security guard. It handles Encryption/Decryption, Data Compression, and formatting so different systems can understand each other.
🔹 3. Layer 7 - Application Layer
The topmost layer where users directly interact with software and apps (like web browsers or email clients).
Key Protocols: HTTP/HTTPS, FTP, and SMTP.

🚀 Together, these three layers take raw data from the network and transform it into the interactive apps and websites you see on your screen!
