Answer:
Explanation:
This connection socket will be created when Host B receives a TCP SYN segment that contains the destination port number 977. This means that there is data that is trying to enter through that port number, as a welcoming socket this destination is available and when data requests access through it the OS creates a connection socket using Host B in order to allow access to the TCP SYN segment.
If a function receives an object as an argument and needs to change the objects member data, the object should be:_____________.
Question
If a function receives an object as an argument and needs to change the objects member data, the object should be:_____________.
A) passed by constant reference
B) passed by reference
C) passed by value
D) none of the above
Answer:
The correct answer is B)
Explanation:
The above question relates to computer programming.
Passing by reference is the same and can be used interchangeably with passing by address.
A special ID used by a computer's procesing unit for recording or tracking data is referred to as a memory address.
When the memory address of a calling function is passed on to the function, the function is said to have been passed by address or reference.
This enables changes to be made to the function or argument directly from the parameter.

wordList is a list of words that currently contains the values ["tree", "rock", "air"]
Which of the following lines will result in the list containing the values ["air", "rock", "air"]
A. wordList[0] = wordList[2]
B. wordList[2] = wordList[O]
C.insertitem(wordList, O, "air")
D. removeltem(wordList,0)
Answer:
A. wordList[0] = wordList[2]
Explanation:
Required
Which line would give ["air", "rock", "air"]
From the question, we have that:
wordList = ["tree", "rock", "air"]
which means that:
wordList[0] = "tree"
wordList[1] = "rock"
wordList[2] = "air"
Analyzing the options.
A. wordList[0] = wordList[2]
This will assign the item in wordList[2] to wordList[0].
and the result would be
So:
wordList[0] = "tree"
would change to
wordList[0] = "air"
The new content of wordList would then be ["air", "rock", "air"]
Option (A) answers the question
The list variable wordList contains three string values, Hence, to obtain the list, ["air", "rock", "air"], the lines wordList[0] = wordList[2] would be used.
List values are indexed from 0 ; hence, tree = index 0 ; rock = index 1 ; air = index 2 To assign the the string "tree" to index 0, then wordList[2] is assigned to wordList[0].wordList[0] is now "air"Hence, the required line of code would be wordList[0] = wordList[2]

Assume you are using the text's array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements and then deque elements. Which indices of the internal array elements hold the remaining elements? a) 0 to 2 b) 7 to 9 c) 2 to 4 d) 1 to 3
Full question:
Assume you are using the text's array-based queue and have just instantiated a queue of capacity 10. You enqueue 5 elements and then deque 2 elements. Which indices of the internal array elements hold the remaining elements? a) 0 to 2 b) 7 to 9 c) 2 to 4 d) 1 to 3
Answer and Explanation:
If you instantiate a capacity of 10 for the queue, you have the queue a capacity of not more than 10 values.
To enqueue means to add an element to the array(if it's not full, n<10)
To dequeue means to delete an element from the array or queue(if n! =0)
From the question, for example:
We create a queue of capacity 10:
Queue q(10);
We add elements/enqueue 5 elements to the queue :
q.queueEnqueue(10);
q.queueEnqueue(5);
q.queueEnqueue(8);
q.queueEnqueue(9);
q.queueEnqueue(2);
If we print this out:
q. queueDisplay()
We would get:
10, 5, 8, 9, 2
We remove elements/dequeue 2 elements from the queue :
q. queuedequeue();
q. queuedequeue();
We print it out:
q. queueDisplay()
8 ,9, 2
We observe that deletion/dequeue starts from the front/first index.
We are left with indices 2, 3, 4 or 2 to 4
Note: the above methods/ functions and objects used are merely for example purposes. The queue uses a floating front design approach.

Partner Exercise: Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km – pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Supply a method drive that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank. Also supply methods getGasInTank(), returning the current amount of gasoline in the fuel tank, and addGas(), to add gasoline to the fuel tank. Sample usage: Car myHybrid = new Car(50); // 50 miles per gallon myHybrid.addGas(20); // Tank 20 gallons myHybrid.drive(100); // Drive 100 miles double gasLeft = myHybrid.getGasInTank(); // Get gas remaining in tank You may assume that the drive method is never called with a distance that consumes more than the available gas. Supply a CarTester class that tests all methods.

Explanation:
A new version of your operating system is released with several changes made to the transport layer protocols. Specifically, TCP has been removed completely but UDP was not changed. What specific changes must be made to your application to accomodate these changes?
Answer:
Throughout the description section down, the overview and per the instance.
Explanation:
Throughout terms of communicating and maintaining a link between the application as well as the network, TCP protocols were essential. The program would not be linked or activated if the TCP has indeed been fully disabled. The essential TCP protocol that enables the application to be linked from over network become HTTP as well as HTTPS. Almost all of the significant protocols needed to operate some programs are based primarily on TCP protocols. Besides, as SSH would not operate as a TCP protocol, the OS would not be remotely linked.Therefore, that would also make it impossible for all the administrators to operate upon this system.

Write in Java:
Given a long integer representing a 10-digit phone number, output the area code, prefix, and line number using the format (800) 555-1212.
Ex: If the input is:
8005551212
the output is:
(800) 555-1212
Hint: Use % to get the desired rightmost digits. Ex: The rightmost 2 digits of 572 is gotten by 572 % 100, which is 72.
Hint: Use / to shift right by the desired amount. Ex: Shifting 572 right by 2 digits is done by 572 / 100, which yields 5. (Recall integer division discards the fraction).
For simplicity, assume any part starts with a non-zero digit. So 0119998888 is not allowed.

Write the function which takes an arbitrary real number p , and returns true if the numeber is equals to some power of 2, i.e. p=2n for some n . Your task is to implement a recursive function power_of_2 withount using loops and library functions.
def power_of_2(p):
if p == 2:
return True
elif p < 2:
return False
return power_of_2(p/2)
print(power_of_2(32))
The function keeps dividing the number by 2 until it is equal to 2 or the number ends up being less than 2. If at some point the number is equal to 2, it is a power of 2 otherwise it's not a power of 2.

Channel logging tokens can be set to all but:________. a. Relaxed b. Strict c. Both versions d. None
Answer:
c. Both versions
Explanation:
The Windows Remote management has hardening levels that could be set to Relaxed, Strict, or None based on the channel binding token associated with a request. This feature could be automatically found in the system or manually configured to a user's choice.
Relaxed settings mean rejection of channel binding token that are not valid and the acceptance of requests with no channel binding tokens, but which may be susceptible to attacks. Strict settings entail an automatic rejection of invalid channel binding tokens. None settings entail the acceptance of all requests with no protection against credential-forwarding attacks.
Sequential and direct access are two methods to locate data in memory. Discuss why major devices now a days use direct access? How can we convert data that is written on a device that supports only sequential access to a device that only support direct access method?
Answer:
Direct data access reduces the speed of retrieving data from memory or storage. Retrieving data and storing it in a cache memory provides direct access to data in the storage.
Explanation:
Sequential memory access, as the name implies, goes through the memory length location in search of the specified data. Direct memory access, provides a memory location index for direct retrieval of data.
Examples of direct and sequential memory access are RAM and tapes respectively. Data in sequential memory access can be access directly by getting data in advance and storing them in cache memory for direct access by the processor.
