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.
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.

Explanation:
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.
What is the advantage of using a translation look-aside buffer (TLB), also called associative memory, in the logical-physical address mapping process? Explain how the logical-physical address mapping logic works using an inverted page table. When does the MMU detect page-fault? Explain four of the main steps for resolving page faults.
Answer:
A) The advantage of using TLB is that it is used for storing the recent transactions of the virtual memory to the physical memory and this is used for the sole purpose of fast retrieval of data
B) When using an inverted table the logical-physical address mapping logic works as a hashing function by connecting pieces of the hardware of logical address and getting them translated to the physical address. this hash function in turn generates the index to the frame table
C) The MMU detect page-fault when there is an exception been raised by the computer when a program is ran to access a memory page and this program is not mapped out by the MMU in the process
The four steps are :
The first step is to check on the memory address requested to make sure of a valid memory request.
The second step is to setup A free frame and a disk operation that is scheduled for getting the necessary page from the disk.
As the the I/O is been completed the processor table is been updated
Finally the Instruction will get restarted from the beginning indicating what might have been caused by a page fault.

Answer:
numB and power
Explanation:
Correct answer edge 2020
The variables have the same scope for the given function is power and base. The correct option is B.
What are variables?A variable in mathematics is a symbol and placeholder for any mathematical object. A variable can specifically represent a number, a vector, a matrix, a function, a function's argument, a set, or an element of a set.
A variable in computer programming is an abstract storage location with an associated symbolic name that contains some known or unknown quantity of information referred to as a value; or, to put it another way, a variable is a named container for a specific set of bits or type of data.
Because power and base are declared in the same container, they have the same scope. Because they are not present in a function, their scope is said to be global.
Thus, the correct option is B.

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]

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.

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.

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.
