Q. Explain Full Duplex data transmission?
- Have two separate Communication channels as well as use each one for simplex Data traffic (in different directions).
- If this is through we have two separate physical circuits each with a "forward" channel (for data) and a "reverse" channel (for acknowledgements).
- In both cases the bandwidth of the reverse channel is approximately entirely wasted and in effect the user is paying for two circuits but using only the capacity of one.
- A better idea is to utilize the same circuit for data in both directions and in this model the data frames from A to B are intermixed with the Acknowledgement frames from A to B.
- By gazing at the kind field in the header of an incoming frame the receiver can tell whether the frame is data or acknowledgement.
Which switching technology can decrease the size of a broadcast domain? Ans) VLAN's are logical ways to break up a huge broadcast domain. To get from VLAN to VLAN you must ha
Q. What is data link of osi model? - The data link layer offers access to the networking media and physical transmission across the media and this enables the data to locate it
GRP uses a composite metric complete up of bandwidth and delay by default, it updates each 60 Seconds and will trigger an update if the topology changes.
Create and simulate a network similar to the one shown here, using the NetML system. The network is a little more complex, as depicted at the right. There is an extra node
define the concept of routing protocol?
It is a basic quantitative property of networks. Delay is a calculate how long it takes for a bit of data to cross across the network from one end to the other. It is calculated in
Q. Describe Physical Layer in OSI layers model? Physical Layer : Controls the transmission of the actual data onto the network. It describes the electrical signals, line state
Describe the method of static and dynamic routing
discuss the interdependence of workstation hardware with relevant software
Q. Show VLAN Membership and Configuration? VLAN Membership - May be classified by - Switch port numbers - MAC addresses - IP addresses - IP multicast addresse
