What is Transport?
The Transport layer is the fourth layer of the OSI model, responsible for end-to-end communication, data flow control, and error recovery between applications on different hosts. It breaks data into segments, ensures they are delivered reliably and in order, and manages retransmission if packets are lost. The two main protocols at this layer are TCP, which provides reliable delivery, and UDP, which prioritizes speed over reliability.
