  • What is OSI model ?Resham Thapa October 1, 2011 at 10:34 AM

    OSI model stands for Open System Interconnection. it provides a description of how network hardware and software work together in ayered fashion to make communication possible. it also helps with trouble shooting by providing a frame of reference that describe how components are supposed to function.

  • Layer 2 (Data Link)Michael Davis October 6, 2011 at 3:40 PM

    Minor correction. Hubs do not use the data link layer, they do not have a cam table or read layer 2 addresses to store and forward frames. Switches use the data link layer, hubs do not. They operate at Layer 1 of the OSI model and just repeat the physical signals they recieve out to all ports except the port the signal came in on.
