UDP and TCP Sessions

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. At the transport layer of the TCP/IP model, you find the User Datagram Protocol. When fast, connectionless transport is desired, then UDP is the protocol to use. In this course, you'll learn about the features associated with connectionless protocols. You'll explore the header fields of UPD, the functions and ranges of port numbers, and the port numbers that are used with UDP. You'll also learn what a socket is and how it is used with TCP/IP. When reliability is necessary for network communications, the Transmission Control Protocol is the protocol of choice. In this course, you'll also learn characteristics of connection-oriented protocols and TCP, as well as the names, sizes, and functions of each TCP header field. You'll explore the importance of eight session flags in the TCP header and how the window size field and maximum segment size options are used to provide flow control. Also, you'll explore the TCP options and their uses, along with the TCP connection and termination process. Finally, you'll learn about the use of sequence and acknowledgment numbers in providing reliable transport and the methods by which TCP manages network congestion. This course was originally created by Global Knowledge (GK).
