My InfoTech Journal: Decoding the Networking Enigma: OSI vs. TCP/IP Reference Models The OSI (Open Systems Interconnection) Reference Model and the TCP/IP (Transmission Control Protocol/Internet Protocol) Reference Model: The OSI Reference Model and the TCP/IP Reference Model are both conceptual frameworks used to understand and standardize how different networking protocols and technologies interact. Here are some areas of comparison: 1. Number of Layers: OSI Model : It consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and TCP/IP Model : It has four layers: Network Interface, Internet, Transport, and Application. 2. L ayer Functionality: OSI Model : Tends to be more comprehensive and abstract, defining each layer's functions independently. TCP/IP Model : Reflects the actual implementation of the Internet and focuses on how protocols are used in practice. 3. Adoption / Use: OSI Model : Less commonly used in practice, but it is still valuab...

- Plan Activation
Specify how and when to activate the plan, including the criteria for declaring a disaster, roles and responsibilities of key personnel, and the process for communicating with stakeholders.
- Communication and Notification Procedures
Establish procedures for communicating with key personnel, stakeholders, and customers during a disruption.
- Testing and Maintenance Procedures
Establish procedures for testing and maintaining the plan to ensure it remains effective and up-to-date.
