Final answer:
The three basic elements used in the OSI model are the Network layer, Data Link layer, and Physical layer. These are the foundational layers of the OSI model, governing physical connections, error correction, and packet delivery in network communications. Option 4.
Step-by-step explanation:
The question is asking about the three basic elements used in the OSI model, which is a conceptual framework used to understand and implement standards for network communication.
The OSI model has seven layers, but the correct answer among the choices provided for the three basic elements is option 4) Network layer, Data Link layer, and Physical layer.
These are the bottom three layers of the OSI model and are essential for communication over a network.
- Physical Layer: Deals with the physical connection between devices and the transmission and reception of raw bit streams over a physical medium.
- Data Link Layer: Responsible for node-to-node data transfer, error correction, and flow control.
- Network Layer: Concerned with the delivery of packets from the source to the destination across multiple networks (routing).
Each layer serves a specific function and is fundamental to network communication. Together, they ensure that transmitted data is successfully delivered from one device to another.
Hence, the right answer is option 4.
