What opeartions will acquire memory from heap? Select all that apply. Group of answer choices malloc new free declaraion
Answer:
malloc, new
Explanation:
Heap memory is that part of the memory which is allocated to the JVM and it is shared by all the executing threads in the application. This memory is used by the programming languages to store the global variables. All the global variables are stored in the heap memory by default. This memory is also known as the dynamic memory.
In C programming, the library function, malloc is mainly used to allocate the block of the memory on the heap.
The new operation also acquires memory form the heap.
Thus, the answer is 'malloc' and 'new'.

Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain fewer than 20 integers.
Ex: If the input is
5 50 60 140 200 75 100
the output is
50 60 75
Answer:
The program in Python is as follows:
num = int(input())
numList = []
for i in range(num+1):
numInput = int(input())
numList.append(numInput)
for i in range(len(numList)-1):
if numList[i] <= numList[-1]:
print(numList[i],end=" ")
Explanation:
This gets input for the number of integers
num = int(input())
This initializes an empty list
numList = []
This iterates through the number of integers and gets input for each
for i in range(num+1):
numInput = int(input())
The inputs including the threshold are appended to the list
numList.append(numInput)
This iterates through the list
for i in range(len(numList)-1):
All inputs less than or equal to the threshold are printed
if numList[i] <= numList[-1]:
print(numList[i],end=" ")
Select the correct statement(s) regarding PONS. a. only MMF cables can be used, since MMF enables greater data capacities compared to SMF b. PONS systems require active amplifiers, since high frequency signals attenuate quickly over distance c. PONS systems use passive devices between OLT and ONT d. all are correct statements
Answer:
The correct statement regarding PONS is:
c. PONS systems use passive devices between OLT and ONT
Explanation:
PON means Passive Optical Network. Based on fiber-optic telecommunications technology, PON is used to deliver broadband network access to individual end-customers. It enables a single fiber from a service provider to maintain an efficient broadband connection for multiple end-users (homes and small businesses). OLT means Optical Line Terminal, while ONT means Optical Network Terminal. They provide access to the PON.

major characteristics of the bus in computer architecture
Answer:
A bus is characterized by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel.
In computer architecture, a bus (related to the Latin “omnibus”, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.)

It's currently 1:00 in the afternoon. You want to schedule the myapp program to run automatically tomorrow at noon (12:00). What two at commands could you use
Answer:
at 12 pm tomorrow
at now +23 hours
Explanation:
The at command could be used in the command line to perform a scheduled command in Unix related systems. The at command coule be ua d to program a complex script or used to perform simple scheduled reminders.
The at command is initiated by first writing the at string followed by the condition or statement to be performed.
Currently (1:00 pm) ; To make a schedule for 12pm then that will be at noon the following day:
at 12:00 pm tomorrow
Or :
Using the number of hours between the current tone and the schedule time : 12 pm tomorrow - 1:00 pm today is a difference of 23 hours ;
Hence, it can be written as :
at +23 hours
When in global configuration mode, which steps are necessary to edit an ip address on an Ethernet interface?
Answer:
I. You should enter interface configuration mode.
II. Configure the IP address and subnet mask.
Explanation:
A node refers to the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.
Some examples of network nodes are modem, hubs, computer, switches, phone and printers.
In Computer networking, network devices such as routers and switches are usually configured (programmed) through the use of specific network commands commonly referred to as configs e.g show int description, config terminal (config t), show IP address, etc.
In Cisco devices, there are five (5) main types of command modes;
1. Sub-interface configuration mode.
2. Interface configuration mode.
3. Line configuration mode.
4. Router configuration method.
5. Global configuration mode.
Global configuration mode is a configuration mode that avail network engineers and end users with the ability to modify or edit the running (global) system configuration of a networking device. Thus, any change effected at the global configuration mode will affect the network device as a whole.
In global configuration mode, the steps which are necessary to edit an ip address on an Ethernet interface include;
I. You should enter interface configuration mode using the "configure terminal" command.
II. Configure the IP address and subnet mask.
See an example below;
"Router(config-if)# IP address 192.168.1.2 255.255.255.0"
This criterion is linked to a Learning OutcomeCreate checkDuplicates method that receives an array of ints, and an int as parameters. It will return true if the int is found in the array, and false if the int is NOT found in the array. Call the checkDuplicates method from both the MegaMillionsLottery constructor, and the getUserPicks() method.
Answer:
Explanation:
The MegaMillions Lottery class was not provided and neither was the getUserPicks() method. Since they were not found online either, I have created the checkDuplicates method so that it works standalone. Therefore, you can simply call the method from wherever you need by pasting the call line where it needs to be called. A test case has been created in the main method so that you can see the method in action. The output is seen in the attached image below.
public static boolean checkDuplicate(int[] myArr, int element) {
for (int x : myArr) {
if (x == element) {
return true;
}
}
return false;

Imagine you are trying to choose what restaurant to visit. You have a list of restaurants, each with a collection of star ratings. You also have a minimum standard; you will only go to a restaurant whose star rating is at least your minimum standard. Write a function called restaurant_rating. restaurant_rating has two parameters. The first is a dictionary, where the keys are restaurant names and the values are lists of ratings. The second parameter is your minimum rating. If a restaurant's average rating is above your minimum rating, you might visit it. If it is not, you won't. restaurant_rating should return a list of restaurants eligible for you to visit. That is, it should return a list of restaurant names from the dictionary whose average ratings (the average of the ratings in their lists) is greater than or equal to your minimum rating. This list should be sorted alphabetically. For example: rest_and_rating
Answer:
The function in Python is as follows:
def restaurant_rating(restaurants,minRatings):
restaurantList = []
for key in restaurants:
if restaurants[key] >= minRatings:
restaurantList.append(key)
restaurantList.sort()
return restaurantList
Explanation:
This declares the function
def restaurant_rating(restaurants,minRatings):
This initializes the list of eligible restaurants
restaurantList = []
This iterates through the restaurant dictionary
for key in restaurants:
If the ratings is greater than or equal to minimum ratings
if restaurants[key] >= minRatings:
The restaurant name is appended to the restaurant list
restaurantList.append(key)
Sort the eligible lists
restaurantList.sort()
Return the list
return restaurantList
