Question 1 Introduction to Physical and Logical Topologies Topology refers to the placement or direction of where of the devices which could be represented Physically or Logically. Physical topology refers to the interconnected of the cable and other hardware components like the Nodes we see or the hub and server and other peripherals we can see and touch. Logical topology refers to the flow of data throw a network which we cannot physically see or tough, to how the devices on the network appear to be connected together. 1.1 Physical Topology is the layout of the Network devices, where they are actually positioned in the physical world and how the direction the information flows on the network like a map. Types of Different Physical Topologies Star Topology In Star topology, all the components of network are connected to the central device called “hub” which may be a hub, a router or a switch. Here all the workstations are connected to central device with a point-to-point connection. So it can be said that every computer is indirectly connected to every other node by the help of “hub”. All the data on the star topology passes through the central device before reaching the intended destination. Hub acts as a junction to connect different nodes present in Star Network, and at the same time it manages and controls whole of the network. Depending on which central device is used, “hub” can act as repeater or signal booster. Central device can also communicate with other hubs of different network. Unshielded Twisted Pair UTP Ethernet cable is used to connect workstations to central node.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
