Routing Information Protocol(RIP): is a dynamic routing protocol which uses hop count as a routing metric to find the best path between the source and the destination network.
If no loopback is configured then the highest active IP address on the interface of the router is considered. First, highest loopback address is considered.
If there is a tie in router priority then highest router will be considered. Router having the highest router priority will be declared as DR. Open shortest path first (OSPF): Open shortest path first (OSPF) is a link-state routing protocol which is used to find the best path between the source and the destination router using its own SPF algorithm.ĭesignated Router(DR) and Backup Designated Router(BDR) election takes place in broadcast network or multi-access network. It depends on Internet Control Message Protocol(ICMP) to provide an error control. Internet Control Message Protocol: Since IP does not have a inbuilt mechanism for sending error and control messages. If data contains ED then, byte is stuffed into data to differentiate it from ED.īit stuffing: Sender stuffs a bit to break the pattern i.e. Framing in DLL: It provides a way for a sender to transmit a set of bits that are meaningful to the receiver.Ĭharacter/Byte Stuffing: Used when frames consist of character. Hamming Code: is a set of error-correction codes that can be used to detect and correct the errors that can occur when the data is moved or stored from the sender to the receiver. Where,L is the number of signal levels used to represent data. Maximum data rate (channel capacity) for noiseless and noisy channels. #Computer networking notes in hindi pdf serial
Let n = collision number or re-transmission serial number.Įarly Token Reinsertion : Efficiency = 1/(1 + a/N)ĭelayed Token Reinsertion : Efficiency = 1/(1 + (N+1)a/N) Efficiency in TDM(polling) = T t / (T poll + T t).>= (Sender’s Window Size) + (Receiver’s Window Size ) (in SR both sender and receiver window are same) NRZ-Inverted/ Differential encoding:In this, the transitions at the beginning of bit interval is equal to 1 and if there is no transition at the beginning of bit interval is equal to 0.It considers the first bit data as polarity change. NRZ-level encoding : The polarity of signals changes when incoming signal changes from ‘1’ to ‘0’ or from ‘0’ to ‘1’.The problem is that the synchronization is lost due to lack of transmissions. Manchester Encoding: When there is a long sequence of 0s and 1s, there is a problem at the receiving end.
Full-duplex Mode: both stations can transmit and receive simultaneously. Half-duplex Mode: each station can both transmit and receive, but not at the same time. Simplex Mode: the communication is unidirectional, as on a one-way street.Only one of the two devices on a link can transmit, the other can only receive. In this topology, it forms a ring connecting a devices with its exactly two neighboring devices. If N devices are connected to each other, then the no. In star topology, all the devices are connected to a single hub through a cable. If N devices are connected, then the number of cables required 1 which is known as backbone cable and N drop lines are required. In mesh topology, every device is connected to another device via particular channel.If suppose, N number of devices are connected with each other, then total number of links required to connect NC 2.īus topology is a network type in which every computer and network device is connected to single cable.
