Assume that you want to click on a link to obtain a Web page. The IP address for this link is not cached in your local host, so a DNS lookup is necessary to obtain the IP address corresponding to that link. Suppose that n DNS servers are visited before your host receives the IP address from DNS. The successive visits incur an RTT of RTT1 ,..., RTTn. Further suppose that the Web page contains one object(e.g. base file) but referencing 10 other objects on the same server, like images, audio, etc. Let RTT0 denote the RTT between the local host and the server containing objects above. Assuming zero transmission time of the objects, how much time elapses when the client clicks on the link until the client receives all the objects with:

(1) Non-persistent connection without parallel TCP connection

(2) Non-persistent connection with 4 parallel TCP connections

(3) Persistent connection without pipelining

Answer:

4, 8 and 12

Explanation:

Given

[tex]Array: 1\ 2\ 3\ 4\ 5\ 6\ 7\ 8\ 9\ 10\ 11\ 12\ 13\ 14\ 15[/tex]

[tex]n = 15[/tex]

Required

Elements that would be found by examining 2 or fewer numbers

To do this, we apply the following binary search algorithm

[tex]head = 1[/tex] at 0-index

[tex]tail = 15[/tex] at 14-index

Calculate the mid-index

[tex]Mid = \frac{0 + 14}{2}[/tex]

[tex]Mid = \frac{14}{2}[/tex]

[tex]Mid = 7th[/tex]

The mid-element (at 7th index) is:

[tex]Mid = 8[/tex]

The element at the mid-index is found by just 1 comparison

For 2 comparisons, we search in either directions

For the lower half, the new head and tail are:

[tex]head = 1[/tex] ---- at 0-index

[tex]tail = 7[/tex] at 6-index

Calculate the mid-index

[tex]Mid = \frac{0 + 6}{2}[/tex]

[tex]Mid = \frac{6}{2}[/tex]

[tex]Mid = 3rd[/tex]

The mid-element (at 3rd index) is:

[tex]Mid = 4[/tex]

For the upper half, the new head and tail are:

[tex]head = 9[/tex] ---- at 8-index

[tex]tail = 15[/tex] at 14-index

Calculate the mid-index

[tex]Mid = \frac{8 + 14}{2}[/tex]

[tex]Mid = \frac{22}{2}[/tex]

[tex]Mid = 11th[/tex]

The mid-element (at 11th index) is:

[tex]Mid = 12[/tex]

The elements at the mid-index of both halves is found by 2 comparisons

Hence, the numbers are: [tex]4, 8, 12[/tex]

The array can be initialized as

1-  An array can also be initialized during declaration. ( as in I )

2- In Initializing an array without assigning values, the default value of each element is zero. ( as in II )

3- An array can be initialized by setting each value of an element to zero by looping the length of the array. ( as in III)

I. It creates an array of 4 elements. The default value of int in java is Zero.

II. It also creates an array of 4 elements and manually initialized all the values to 0.

III. It creates an array of 4 elements. and uses a loop to manually initialized all the values to 0.

2) Output is 7 i.e Option(D).

total =total+values[total]; => total = 3+values[3];

=> total=3+(-2) => total=3-2 =>total=1.

total =total+values[total] =>total =1+values[1]

=>total= 1+6 =>total =7.

3)Option(D) i.e 2 8 10.

In If condition it is checking whether the element in the array is Positive and also it is divided by 2 with 0 reminder.
