Answer:

10

Explanation:

An enqueue operation is a function that adds an element(value) to a queue array. A dequeue operations removes an element from a queue array. Queue arrays follow a first-in-first-out approach, so elements that are first stored in the queue are removed/accessed first(enqueue operations add elements at the rear of the queue array).

The following operations leave 10 elements in the queue of array size 12 after its done:

10 enqueue operations= adds 10 elements

5 dequeue operations= removes 5 elements( 5 elements left in queue)

6 enqueue operations= adds 6 elements(11 elements in queue)

10 dequeue operations= removes 10 elements(1 element left in queue)

8 enqueue operations= adds 8 elements(9 elements in queue)

2 dequeue operations= removes 2 elements(7 elements left in queue)

3 enqueue operations= adds 3 elements(10 elements in queue)

Therefore there are 10 elements in the queue after enqueue and dequeue operations.

Discuss TWO changes in ICMP that took place with the development of IPV6 and indicate why those changes were made.
max2010maxim [7]

Answer:

Over and above basic medication signaling, but instead of signaling, ICMPv6 could be used for other objectives. It could be utilized for the below description.

Explanation:

That falls into the same category even though IPv4 does through ARP.  

  • <u>Neighbor Discovery</u>:

Used mostly for control of hosts but instead multichannel interface setup.  

  • <u>Router Discovery</u>:

Trying to manage Handheld IPv6 hand-offs.  

Throughout IPv6, within a week of negligible and sometimes more broadcast group, this same ICMPv6 response can begin. The whole last extension connector before another ICMPv6 connector contains a 58-value new Header field.

4.8 code practice question 2
Anna35 [415]

Answer:

Written in Python

for count in range(88, 42,-2):

    print(count,end=' ')

Explanation:

The programming language is not stated.

However, I used python to answer the question.

First, we need to loop from 88 to 44 with a difference of -2 in each term.

This is implemented as

for count in range(88, 42,-2):

Which means to start at 88 and ends at 42 - (-2) which is 44 with an increment of -2

Next, is to print the current iterating value;

This is implemented using print(count)

However, since all values are to be printed on a line, there's a need t modify the statement as: print(count,end=' ')
