Question: Which layer of the osi model defines services to segment and reassemble data for individual communications between end devices?

The Transport Layer (Layer 4) of the OSI model is responsible for segmenting and reassembling data for individual communications between end devices. This layer ensures reliable data transfer by breaking down data into smaller segments, assigning sequence numbers, and reassembling them in the correct order at the destination. It also provides error detection and recovery, as well as flow control to prevent data congestion.

Key protocols in this layer include TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
