Transport layer protocols bridge the gap between the raw packets of the internet layer and the refined needs of application. It is necessary for user-space programs as otherwise it would be difficult for user-space programs to deal with a bunch of raw packets the way that kernel does. Its important to know how the computer presents paclet data it recieves from other hosts to its running processes.
Transport layer protocols play a crucial role in networking by acting as a bridge between the raw packets handled by the internet layer and the specific requirements of applications. They are essential for user-space programs because dealing directly with raw packets, as done by the kernel, can be challenging for these programs. Understanding how the computer presents packet data received from other hosts to running processes is vital for efficient communication between applications over a network.
