Router with three interfaces connects 3 subnets in a 184.108.40.206 network. Their subnet mask’s are given. Match the following IP’s and Interfaces they belong to?
Find the latency of Token Ring (in bits) where data rate of link is 20 Mbps and 40 stations separated by 100 meters and bit delay at each station is 1 bit. (Assume propagation speed as)
Assume 10 Mbps Ethernet and two stations A and B on it’s same segment. The RTT between two nodes is 650 bit times. A and B start transmitting frame and collision occurs and both sends 30-bit jam signal. Find the time at which both nodes A and B sense an idle channel (in)
Which of the following statement is TRUE?
In a RSA cryptosystem a particular A uses two prime numbers p = 11 and q =17 to generate her public and private keys. If the public key of A is 11. Then the private key of A is ____________.
During message transfer between two computer system present in a network connected with n numbers of routers, which is variable?
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. Let m be the data bit that we need to send and r be the number of redundant bit, that we added along with the data to detect and correct the error. The formula to calculate the number of redundant bit is:
The message 111010 is to be transmitted using the CRC polynomial to protect it from errors. What will be the CRC generated ?
