A Cryptographich hash is created by using a secure hash function to generate a hash value for a message and then encrypting the hash code with a private key.
Answer:
Check the explanation
Explanation:
Going by the question above,there are 2 routers in a sequence amid Host A and Host B and using store-and-forward routing.
So that time would conprise of both propagation delay and transmission time
Propagation delay is nothing but the time taken for traveling.
Transmission delay is the amount of delay time from the beginning to end of transmission)
Now,
Propagation delay = distance traveled / speed of propagation
= 161200 / 2.7 *108 = 59703703.70 * 10-8 mili sec
Transmission delay:
= packet size / bandwidth
= 4 / (9.1 * 1024) = 4.2925 * 10-1 mili sec
Let us assume routers have zero (0) processing time
total time = Transmission delay by host A + Transmssion delay by router1 + Transmssion delay by router2 + propagation time
= 3 * ( 4.2925 * 10-1 ) + (59703703.70 * 10-8)
= 1.28775 + 0.5970370370 ms
= 1.884787 ms
Answer:
PING
Explanation:
To check if there's still connectivity between the computer and server, I would use the ping command.
The ping command is primarily a TCP/IP command. What this command does is to troubleshoot shoot. It troubleshoots connection and reachability. This command also does the work of testing the name of the computer and also its IP address.
