Discuss ISO-OSI Reference Architecture in details.

The ISO-OSI Reference Model is a conceptual framework used to understand network communication and design, aiming to standardize and simplify the way computer systems communicate over a network. It is based on a layered approach where each layer has a specific function, and the interdependencies between layers help manage the complexities of communication. Developed by the International Organization for Standardization (ISO), this model divides the communication process into seven distinct layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

### 1. Physical Layer
The Physical layer is the lowest layer of the OSI model. Its primary function is to transmit raw bits over a physical medium like cables, radio waves, or fiber optics. It defines the hardware elements involved ___ ______ ________ ________ ___ _____.
