The OSI Model Made Simple Free Download
Master the Open Systems Interconnection (OSI) model by following along with networking expert Zanis Khan. This topic is a subset of Zanis Khan’s course, The Definitive Preparation Guide to the CCNA (Cisco Certified Network Associate) Certification Exam. OSI is a conceptual model that standardizes the communication functions of a network without regard to its underlying internal structure and technology. Become familiar with the seven-layer architecture which includes the Physical, Data Link, Network, Transport, Session, Presentation, and Application layers. A more stripped down version is the TCP/IP model which includes the four levels of Network Interface, Internet, Transport, and Application. Learn the high-level responsibilities of each layer.
