Murray Gell-Mann is likely one of the top physicists of the area. He used to be provided the Nobel Prize in Physics in 1969 for his paintings at the class and symmetries of basic debris, together with the approximate SU(3) symmetry of hadrons. His record of courses is extraordinary; a couple of his papers became landmarks in physics.

10. Virtual LANs. These are configured on the layer 2 switches, and layer 3 devices provide a means for moving traffic between the VLANs. 1. 2. Review Questions 1. 2. 54 You work for a large company that needs to connect four buildings with a high-speed, highbandwidth backbone. They are all on the same city block, and fiber already connects the buildings. There are multiple departments in each building and all run multiple protocols. The company already owns Cisco Catalyst 6000 series switches, which you can use for the distribution layer.
9. What devices provide multicast control and packet-based security? 10. What breaks up broadcast domains in a layer 2 switched network? Answers A layer 3 device, usually a router. Layer 2 devices do not break up broadcast domains. A layer 2 device, typically a switch. Although routers break up both collision domains and broadcast domains, layer 2 switches are primarily used to break up collision domains. 3. Segment, packet, frame, bits. It is important to understand the question. This question asked for the units of data, which shows how data is encapsulated as user data goes from the Application layer down to the Physical layer.
Now that you have a sense of the OSI model and how routers and switches work together, it is time to turn our attention to the specifics of each layer of switching technology. Chapter 1: The Campus Network 35 36 Chapter 1: The Campus Network Layer 2 Switching Layer 2 switching is hardware based, which means it uses the Media Access Control (MAC) address from the host’s network interface cards (NICs) to filter the network. Switches use application-specific integrated circuits (ASICs) to build and maintain filter tables.
