Suppose an IP packet is fragmented into 10 fragments, each with a 1% (independent) probability of loss. To a reasonable approxim
Marysya12 [62]

Answer:

a. 0.01

b. 0.001

c. The identification field of the packet fragment can be used to uniquely identify and collate the fragments lost in transmission.

Explanation:

The probability of losing a packet is 10% or 0.1, so the probability of losing the packet twice during transmission;

= 0.1 x 0.1 = 0.01

When any fragments have been part of the transmission, the probability of the packet is dependent on the fragments;

= 0.01 x 0.1 = 0.001

The identification field is a unique 16-bit value assigned to an IPv4 packet, when a packet is fragmented for transmission, its field is used to collate the unique fragments in the packet.

What is the output of the following code?
Lynna [10]

Answer:

The output is 24

Explanation:

Given

The above code segment

Required

The output

We have (on the first line):

x = 6

y = 3

z=24

result=0

On the second line:

result = 2*((z/(x-y))\%y+10)

Substitute the value of each variable

result = 2*((24/(6-3))\%3+10)

Solve the inner brackets

result = 2*((24/3)\%3+10)

result = 2*(8\%3+10)

8%3 implies that, the remainder when 8 is divided by 3.

The remainder is 2

So:

result = 2*(2+10)

result = 2*12

result = 24

<em>Hence, the output is 24</em>
