OSI Model Layer 4 Transport

OSI Model Layer 4 Transport

This lesson covers Layer 4, the transport layer of the OSI model. This layer provides us with management and control and also helps us to transfer data that we send and receive. It helps splits communications into different packages using either Transmission Control Protocol (TCP) or User Data Protocol (UDP). These protocols provide for either verification or no verification of delivery.
