From web browsing to e-mail, the most widely used applications in TCP/IP networks use application layer protocols that rely on TCP to provide reliable delivery. In this course, you'll explore the features and functions of Telnet and the internal operations of FTP. You'll also learn about the codes used in FTP, SMTP, and HTTP and examine the differences between SMTP, POP, and IMAP. Key network support activities are supported by application layer protocols that rely on the User Datagram Protocol. In this course, you'll also learn about the Trivial File Transfer Protocol and how to identify the different TFTP messages. You'll explore the use of Simple Network Management Protocol in network management, as well as the role of the network management station SNMP agent and Management Information Base in SNMP. Finally, you'll learn about the use of remote networking monitoring. Voice over IP is a good example of applying the TCP/IP protocols to carry time sensitive information such as voice or video. VoIP relies on various protocols to deliver new and innovative ways of communicating over TCP/IP networks. You'll learn about the TCP/IP protocols that support VoIP, the benefits of VoIP, and the basic components of a VoIP system. You'll explore how Session Initiation Protocol sets up a telephone call, the use of session description protocol, and some common VoIP codecs. You'll also learn about Real-time Transport Protocol.
