VPNs and Wifi networks use tunneling to send data privately over a network
Answer:
<em>During a traceroute, the router decreases the Time To Live values of the packet sent from the traceroute by one during routing, discards the packets whose Time To Live values have reached zero, returning the ICMP error message ICMP time exceeded.</em>
Explanation:
Traceroute performs a route tracing function in a network. It is a network diagnostic commands that shows the path followed, and measures the transit delays of packets across an Internet Protocol (IP) network, from the source to the destination, and also reports the IP address of all the routers it pinged along its path. During this process, the traceroute sends packets with Time To Live values that increases steadily from packet to packet; the process is started with Time To Live value of one. <em>At the routers, the Time To Live values of the packets is gradually decreased by one during routing, and the packets whose Time To Live values have reached zero are discarded, returning the ICMP error message ICMP Time Exceeded</em>
Answer:
Following are the missing code to this question:
break;
Explanation:
In the given python code, a method "retry" is defined, that accepts two-variable, that is "operation and attempts" in its parameters, inside the method a for loop is defined that uses the n variable to holds attempt values and define the conditional statement.
- Inside if block, it checks if the operation value is true, it will print a successful attempts values and break the condition, otherwise it will goto else block.
- In the else block, it will print failed attempts values.
Answer:
see explaination
Explanation:
void allocate(double *q,int size)
{
if(size<=0)
q = new double; //Allocates a single double
else
q = new double[size]; //Allocates an array of doubles
}
This function allocates new space for a double array. It alter its pointer argument to point to the newly allocated space.
