Which OSI layer handles flow control, data segmentation, and reliability?1 pointApplicationPhysicalTransportData Link

The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and implement network protocols in seven layers. The layer that handles flow control, data segmentation, and reliability is the Transport layer. Here’s a step-by-step explanation:

1. Flow Control:

   • The Transport layer manages the rate of data transmission between two nodes to ensure that a sender does not overwhelm a receiver with too much data at once. This is crucial for maintaining efficient and reliable communication.

2. Data Segmentation:

   • At the Transport layer, data from the application layer is divided into smaller, manageable pieces called segments. This segmentation allows for more efficient data transfer and reassembly at the receiving end.

3. Reliability:

   • The Transport layer ensures that data is delivered accurately and in the correct sequence. It uses mechanisms like error detection and correction, acknowledgments, and retransmissions to provide reliable data transfer.

Given these functions, the correct answer is:
