TCP is used in nearly every transaction users have on a network. Surfing the web, checking your email, watching a streaming video, all use TCP as the transport layer protocol. TCP has a very precise operation, and understanding how it works leads to becoming a great network troubleshooter. In this course, TCP and UDP Operation for Cisco CCNA 200-125/100-105, you will learn about the TCP three-way handshake, port number addressing, and sequence and acknowledgment numbers used for reliable communication. Next, you explore at TCP's less reliable partner, UDP. Finally, you'll understand where UDP is used and why you use it. By the end of this course, you'll know how the TCP three-way handshake works, as well as how TCP uses sequence numbers to ensure successful data delivery.
Course Overview Hi, everyone, my name is Ross Bagurdes, and welcome to my course, TCP and UDP. I'm a network engineer with 20 years experience building and managing enterprise networks and teaching people about them. TCP, Transmission Control Protocol, is a transport layer protocol, and is used in nearly every data communication on a network. Understanding its operation can lead to outstanding troubleshooting skills and is truly fundamental knowledge for a network engineer. In this course, we'll learn about TCP operation and reliable communication, as well as UDP, User Datagram Protocol, which is TCP's less reliable sibling. By the end of this course, you'll know how the three-way handshake works, as well as how TCP uses sequence numbers to ensure successful data delivery. Before beginning the course, you should be familiar with IP addressing and network operation, which can be learned in the previous videos in this CCNA Series. From here, you should comfortable diving in to Application Layer Protocols and the rest of the courses in the CCNA Series. I hope you'll join me on this journey to learn the TCP three-way handshake and reliable communication with the TCP and UDP course at Pluralsight.
