A New Year is well underway. Are you on track with any certification pursuits as part of a New Year's Resolution from January 1st? Have you set any goals to “learn a little everyday” as part of a life-long learning mindset? We strive to help all of our Cisco Learning Network Premium subscribers grow by providing quality educational content. We’ve added some valuable Cisco CCNA Routing and Switching content this month, so read on!
The OSI and TCP/IP model describe the structure of a network and how hosts communicate end-to-end. In this series you learn the history of both the OSI and TCP/IP model. You also learn about the encapsulation and decapsulation processes as data moves up and down the layers of the protocol stack.
In this series, the Cisco Learning Network explores Protocol Data Units (PDUs) within the TCP/IP model. These lessons provide an overview of PDUs, examine them at each TCP/IP layer, and conclude with a review session.
All the best on your educational pursuits.
Thank you for reading.
