FTP works on TCP ports 20 and 21. The TCP and UDP transport layer protocols use port numbers to manage multiple, simultaneous conversations. retrieve web pages from a server and interact with the pages using their web Generally on GNU . header. The purpose of network hardware and protocols 1 Layered network protocols. An FTP server can easily be set up with little networking knowledge and provides the ability to easily relocate files from one system to another. The transport layer protocols need to track this activity and ensure that received data is directed to the correct application layer protocol otherwise, for example, webpage data may be directed towards an email application.
