Answer:
Your computer now has the IP address of that website cached, and no longer has to lookup the IP address of that domain name. The TTL of the first query is bigger than the TTL of the second query as less time was taken to execute the request.
Explanation:
On the first request to the website, the computer needs to contact other machines to find the record of the IP address.
On the second request, the computer already has the IP address and can use that to connect.
An example I believe of relational context is when I was out with my son on the weekend (he has a developmental disability) and we had agree I would buy him a 1/2 sub sandwich the day before but then he said I would like a McFlurry so I said okay and then he said so you mean I can have a McFlurry and a sub and I thought oh oh I stuck my foot in it so I said but it must be only a 1/2 sub so he said no I want a full sub then and no mcflurry so I agreed so from the original 1/2 sub idea the idea evolved to a full sub which was affected by the warm sunny summery weather in the afternoon and seeing people lined up at ice cream shops so the idea developed in relation to the weather, how hungry he was and the social aspect people buying ice cream.
Answer:
The correct output of this question is "Sneezy Sleepy".
Explanation:
In the given code firstly we create the object of the integer class that is first in this we pass the integer value that is 7. Then we declare another second integer variable is this variable we pass object as a reference. Then we use the two conditional statements. In the first, if block we check that the object of the class is equal to the reference variable. If it is true it prints Sneezy. otherwise, it will print Grumpy. In second if block we check that the object of the class is equal to the reference variable. but in this time we the equals() function it is the same as(==). If the condition is true it prints Sleepy. otherwise, it will print Doc. So the output of the code is Sneezy Sleepy.

Answer: You need a temporary variable to hold the value 3
Explanation:
So, aList[0] is 3 and aList[1] is 19, if it will be as it is you litteraly say to the compiler to change aList[0] to aList[1] at this moment aList[0] is 19 and aList[1] also is 19 and if you try to change aList[1] to aList[0] it will not change its value because they are the same.
You need temp variable to keep one of the values.
