What is the difference between blocking calls and non-blocking calls? Explain 2 methods to remove blocking from your application.
Answer:
integrgrg
Explanation:
integrety or not iim not
Non-blocking code does not prevent execution from continuing while blocking code prevents execution from continuing until the operation is complete. Blocking calls hold off on returning until the I/O operation is finished. Synchronous results are returned from it.
What is the difference between blocking calls and non-blocking calls?Blocking calls hold off on returning until the I/O operation is finished. Synchronous results are returned from it. During the waiting period, nothing else in that process happens. In contrast, a non-blocking call uses a different method to check for completion and returns right away without any results.
Non-blocking code does not prevent execution from continuing while blocking code prevents execution from continuing until the operation is complete. Blocking occurs when subsequent JavaScript in the Node. js process needs to wait until a non-JavaScript activity is finished, according to the documentation for the language.
A program that is non-blocking does not prevent the execution of subsequent operations. Non-blocking techniques run in an asynchronous fashion. Asynchronously refers to the possibility that the program may not always run line by line.

Write a program that takes a positive integer argument N, and prints out the average, minimum, and maximum (in that order) of N uniform random numbers that it generates. Note that all three statistics should be over the same sequence of N random numbers python
Answer:
from random import seed, choices
from statistics import mean
number = int(input("Enter integer number: "))
if number > 0:
try:
data = range(number+1)
# to generate a pseudo-random number list.
seed(10)
# you can also use: num_list = [random.randint(0, number+1) for i in data]
num_list = choices(data, k=len(data))
print(num_list)
mean_val = round(mean(num_list), 2)
min_val = min(num_list)
max_val = max(num_list)
except ValueError:
print("Must be an integer value.")
print('Avg number: {}\nMax number: {}\nMin number: {}'.format(mean_val, max_val, min_val))
Explanation:
To generate random items in a list of integers, the random choices method is used and a sequence is passed as an argument. The average, maximum, and minimum number of the list is calculated and displayed.
Let g(x) = cos(x/2) - 3x. Let f(x) = 2x + 5. What is g(f(x))?
Answer:
f = 2
Explanation:
g(x) = cos(x/2) - 3x=w where w=-3.5 or -1 or -38.5
13– (13/2)-3*13=-3.5 (1st d value of g(x))
-1-(-1/2)-3*(-1)=-1 (the 2nd possible value)
g(x) = cos(x/2) - 3x=-1 where the first x=13 and the 2nd one=-1
where the first x=-1 and the 2nd one=-38.5 (the 3rd value)
g(x) = cos(x/2) - 3x)=0 where cos(x/2=-3.5
g(f(x)) = cos(f(x)/2) - 3 aka 0.5 f(x) = cos(2x+5 aka 7x) (x/2 - 3 =aka -1 );
(2x+5) = 7x by definition but the equation has to be set to 7 to find x)
(7x/2 -6x=0) -7 on both sides
x/2–6x=-7
x/2= 13
26/2=x
x=13 (these values are set up for 2x+5=7.
13-(-7)=-7
13-6+-1=-7
the 2nd x=-1
gfx=cos*2*x i.e cos*2*13 or cos*2*-1
cos*2*13=26
cos*2*(-1)=-1
cos=1
(cos*2*13)=the 1st gfx value=26 basically.
( cos*2*(-13)=-26 (the 2nd gfx value)
cos*2*(-1)=-`1 (the 3rd gfx value)
f=2

Supporting mobility and smartphone apps is important to MasterCard. What challenges does MasterCard face in rolling out smartphone payment systems? Which of these do you think will be most difficult to address? Why?
(BEWARE OF PLAGARISM, DO NOT JUST COPY PASTE FROM THE INTERNET)
Answer:
Throughout the clarification portion below, the definition of the concern is mentioned.
Explanation:
SecurityThe best characteristic that arrives in and out of mind when people think concerning mobile payments would be security. The greater problem for customers and suppliers is this. As mobile purchases are made, suppliers store card information for potential purchases. Anyway, several vendors note that the data would not be kept on either the service side, however people are rather fearful of sending details.
TechnologySome people seem to agree that there's been a significant change in technology in recent years. Especially if we get to see that the frequency of internet access also isn't up to standards in most countries. And in some countries, the network is unavailable and will not link.
Different mobile platformsThe very next thing that needs to be confronted seems to be the multiple platforms crisis. Mobile now has multiple systems and apps that a company produces towards one platform simply doesn't work on yet another platform. Platforms including Android exist.
Fewer usersThat very many consumers are accustomed to the current payment service, such as currency, credit card, debit card, pockets including a few others. Because they do not believe them, they weren't in a condition to introduce a different payment system. This has become one of the smartphone transaction system's obstacles.
Required incentivesIncentives are offered whenever the purchase is done by cards or wallets, but they are not accessible when another payment has been made via the billing system for smartphones. To draw more customers, they can do good promotions.
Tedious circulate of payments and incoherent consumer experienceThe payment water flowing through several iterations through both the smartphone financial services for compensation. Although if we take into account the payment movement of cards, it is very straightforward. Some manufacturers have now launched embedded chips that are safer than magnet circuits. The transaction seems to be much better on these chips, and performance is instantaneous and smooth.

If after a call to fork, we want any updates to memory by the parent process to be visible to the child process, and vice-versa, what flag should be included in the fourth argument of mmap?
Answer:
MAP_SHARED
Explanation:
The MAP_SHARED should be included in the 4th argument of map. When we have a MAP_SHARED set, then we have it that it is preserved across a fork2 system call.
It is visible immediately in every parent, siblings or child processes. This is to say that any change that is made to this mapping is immediately seen by readers.

discuss data and its types from computer programming and data analysis prospectively?
Answer:
With the use of data and their types the extent of how much data can be stored can get insanely large. types like doubles and longs allow for a range of values nearly incomprehensible in their size for storing user information, web pages, games ect. Using them essentially allows you to plan for the future of the size of whatever you're creating. On top of that, it allows for a preciseness not typically able to be reached without these types.
Raw information that is made up of simple facts and figures is referred to as data. Computer data can take many different forms, including financial data, notes, photographs, and coding.
What is data?The amount of data that may be kept can become absurdly vast depending on how it is used and the categories of data. For storing user information, web pages, games, etc., types like doubles and longs provide for a range of values almost incomprehensible in their vastness.
Utilizing them effectively enables you to plan for the magnitude of whatever you're developing in the future. Additionally, it enables a level of precision that is often not possible without these types.
Therefore, raw information that is made up of simple facts and figures is referred to as data. Computer data can take many different forms, including financial data, notes, photographs, and coding.

A flashlight bulb uses 2.4 W of power when the current in the bulb is 0.8 A. What is the voltage difference?
Answer:
3 Volts.
Explanation:
Answer:
3 Volts
Explanation:
Because Power = Voltage x Current, so if you substitute the values into the equation, it would be :
2.4 W = Voltage x 0.8 A
Then if you rearrange the equation, it would be :
2.4 W / 0.8 A = Voltage
Which is :
3 V = Voltage

A2 Suggest why the Petri dish and agar jelly needed to be sterile.
A Petri dish (Petri plate) is a shallow cylindrical glass lidded dish that is typically used to culture microorganisms (agar plates). There are glass and plastic Petri dishes, and both can be sterilized (using an autoclave) and re-used. Before being used for culture purposes, it is important to ensure that the Petri dish is not only clean, but also sterile. This helps prevent the contamination of the new culture.Agar is a polymer made up of various sub-units of galactose and various species of red algae. Although it has other uses including culinary and dentistry, agar plays an important role in microbiology as culture media for a variety of microorganisms.As compared to some of the other alternatives like gelatin, agar has a number of advantages which include:Cannot be easily degraded by microorganism Stronger Firmer than gelatin
