Network+ N10-009 Layer 4 (Transport)
The Transport layer acts as the dividing line between the upper (application-oriented) layers and the lower (network-oriented) layers of the OSI model, offering essential services like segmentation, reassembly, error detection, flow control, and reliable end-to-end delivery through protocols such as TCP and UDP.
