Final answer:
The correct answer to the question regarding the OSI model layer that segments/reassembles packets and handles flow control is the Transport Layer. It is responsible for reliable data transfer and can control the flow to ensure the data integrity is maintained throughout transmission.
Step-by-step explanation:
The layer of the OSI model that segments and reassembles data packets, as well as manages flow control, is the Transport Layer. This layer ensures that data are transferred from point A to point B reliably and without errors. It provides services such as connection-oriented communication, reliability, flow control, and multiplexing.
The Transport Layer is responsible for breaking down large messages into smaller segments on the sender's side and reassembling them on the receiver's side. It also handles the flow control to prevent a fast sender from overwhelming a slow receiver. Additionally, it ensures that data packets are delivered in sequence and without loss or duplication.
Considering the options provided:
- a. Transport Layer
- b. Network Layer
- c. Data Link Layer
- d. Physical Layer
the correct answer is a. Transport Layer.
