The TCP/IP transport layer transports data between applications on source and destination devices. Familiarity with the transport layer is essential to understand modern data networks. This module will describe the functions and services of this layer. Many of the network applications that are found at the TCP/IP application layer are familiar to most network users. HTTP, FTP, and SMTP are acronyms that are commonly seen by users of Web browsers and e-mail clients. This module also describes the function of these and other applications from the TCP/IP networking model. This module covers some of the objectives for the CCNA 640-801, INTRO 640-821, and ICND 640-811 exams. Students who complete this module should be able to perform the following tasks: Describe the functions of the TCP/IP transport layer Describe flow control Explain how a connection is established between peer systems Describe windowing Describe acknowledgment Identify and describe transport layer protocols Describe TCP and UDP header formats Describe TCP and UDP port numbers List the major protocols of the TCP/IP application layer Provide a brief description of the features and
