CISSP®- The CIA Triad - Part 1 - Confidentiality, Integrity, and Availability

The video tutorial provides a foundational understanding of networking, covering key concepts such as simplex, half duplex, and full duplex communication. It explains the differences between baseband and broadband, and the roles of intranet and extranet. The tutorial also compares circuit and packet switching, highlighting their costs and uses. Finally, it discusses various types of networks, including PAN, LAN, MAN, WAN, and VPN, emphasizing their characteristics and applications.
