Define firewall ?with example
Explanation:
it acts as a barrier between a trusted system or network and outside connections, such as the Internet. However, a computer firewall is more of a filter than a wall, allowing trusted data to flow through it. ... For example, a basic firewall may allow traffic from all IP.
if my answer helps you than mark me as brainliest.
Answer:
hope this helps
Explanation:
Firewalls are software or hardware that work as a filtration system for the data attempting to enter your computer or network. Firewalls scan packets for malicious code or attack vectors that have already been identified as established threats.And also firewall is a network security device that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules.
Create a Python dictionary that returns a list of values for each key. The key can be whatever type you want.
Design the dictionary so that it could be useful for something meaningful to you. Create at least three different items in it. Invent the dictionary yourself. Do not copy the design or items from some other source.
Next consider the invert_dict function.
def invert_dict(d):
inverse = dict()
for key in d:
val = d[key]
if val not in inverse:
inverse[val] = [key]
else:
inverse[val].append(key)
return inverse
Modify this function so that it can invert your dictionary. In particular, the function will need to turn each of the list items into separate keys in the inverted dictionary.
Run your modified invert_dict function on your dictionary. Print the original dictionary and the inverted one.
Describe what is useful about your dictionary. Then describe whether the inverted dictionary is useful or meaningful, and why.

What are the differences between sequential and random files? Which one do you think is better and why?
Answer:
Sequential is better
Explanation:
Sequential is more organized while the more easier to make but less dependable one is random.
sequential is used for things such as date of birth, or where someone was born.
you can't do that with a random file.
Write a program that creates an an array large enough to hold 200 test scores between 55 and 99. Use a Random Number to populate the array.Then do the following:1) Sort scores in ascending order.2) List your scores in rows of ten(10) values.3) Calculate the Mean for the distribution.4) Calculate the Variance for the distribution.5) Calculate the Median for the distribution.
Answer:
Explanation:
The following code is written in Python. It uses the numpy import to calculate all of the necessary values as requested in the question and the random import to generate random test scores. Once the array is populated using a for loop with random integers, the array is sorted and the Mean, Variance, and Median are calculated. Finally The sorted array is printed along with all the calculations. The program has been tested and the output can be seen below.
from random import randint
import numpy as np
test_scores = []
for x in range(200):
test_scores.append(randint(55, 99))
sorted_test_scores = sorted(test_scores)
count = 0
print("Scores in Rows of 10: ", end="\n")
for score in sorted_test_scores:
if count < 10:
print(str(score), end= " ")
count += 1
else:
print('\n' + str(score), end= " ")
count = 1
mean = np.mean(sorted_test_scores)
variance = np.var(sorted_test_scores, dtype = np.float64)
median = np.median(sorted_test_scores)
print("\n")
print("Mean: " + str(mean), end="\n")
print("Variance: " + str(variance), end="\n")
print("Median: " + str(median), end="\n")

A hierarchy chart can be helpful for a. planning the functions of a program b. naming the functions of a program c. showing how the functions of a program relate to each other d. all of the above e. a and c only
Answer:
Hence the correct options are option B and option C.
Explanation:
Hierarchy Chart means top to bottom structure 0f a function or a program or an organization.
Planning the functions of a program means deciding beforehand that what are the functions of a program and what to try to do and when to try to, hierarchy Charts are often helpful In doing/knowing this all.
Showing how the functions of a program relate to every other means what's the connection between two functions for instance if we have a hierarchical chart of a corporation member then we'll have the connection among the members of the team i.e., first, we'll have CEO, then Manager then team/ project lead then team members and by using hierarchical chart ready to " we will be able to identify the connection among them. during a similar way, we will have a relationship among the functions of a program using the hierarchical chart.

Mario is giving an informative presentation about methods for analyzing big datasets. He starts with the very basics, like what a big dataset is and why researchers would want to analyze them. The problem is that his audience consists primarily of researchers who have worked with big data before, so this information isn’t useful to them. Which key issue mentioned in the textbook did Mario fail to consider?
Answer:
Audience knowledge level
Explanation:
The Key issue that Mario failed to consider when preparing for her presentation is known as Audience knowledge level.
Because Audience knowledge level comprises educating your audience with extensive information about the topic been presented. she actually tried in doing this but she was educating/presenting to the wrong audience ( People who are more knowledgeable than her on the topic ). she should have considered presenting a topic slightly different in order to motivate the audience.

The advantage of returning a structure type from a function when compared to returning a fundamental type is that a. the function can return multiple values b. the function can return an object c. the function doesn’t need to include a return statement d. all of the above e. a and b only
Answer:
The advantage of returning a structure type from a function when compared to returning a fundamental type is that
e. a and b only.
Explanation:
One advantage of returning a structure type from a function vis-a-vis returning a fundamental type is that the function can return multiple values. The second advantage is that the function can return can an object. This implies that a function in a structure type can be passed from one function to another.

Page scaling mode helps increase or reduce the size of the worksheet to fit within the set number of pages to be printed. Which option re-scales
a worksheet vertically?
To re-scale a worksheet vertically, select the number of pages in the height text box in the____group.
Answer:
Scale to fit.
Explanation:
The scale to fit group can be found in the page layout tab as it is used to deal with display of functionalities of a document and spreadsheet program. The scale to fit requires input in the width option which will dictate the width of the page in which to place the documents on. By specifying 1 for the width, this means that the document will be rescaled to fit on a single page. The automatic option may be selected for the height option which will allow the program to make an auto Decison in the shrinkage depending on the stated width value.
What is the relationship between an organization’s specific architecture development process and the Six-Step Process?
Answer:
It is a method of developing architecture in various stages
Explanation:
The organization-specific architecture developmental process is a tested and repeated process for developing architecture. It made to deal with most of the systems. It describes the initial phases of development. While the six step process is to define the desired outcomes, Endorse the process, establish the criteria and develop alternatives. Finally to document and evaluate the process.Consider a short, 90-meter link, over which a sender can transmit at a rate of 420 bits/sec in both directions. Suppose that packets containing data are 320,000 bits long, and packets containing only control (e.g. ACK or handshaking) are 240 bits long. Assume that N parallel connections each get 1/ N of the link bandwidth. Now consider the HTTP protocol, and assume that each downloaded object is 300 Kbit long, and the initial downloaded object contains 6 referenced objects from the same sender.
Required:
Would parallel download via parallel instances of non-persistent HTTP make sense in this case? Now consider persistent HTTP. Doyou expect significant gains over the non-persistent case?

Copy the code above into your program but write all the other code for this assignment yourself. Do not copy any code from another source.
Write a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False.
Implement has_duplicates by creating a histogram using the histogram function above. Your implementation should use the counts in the histogram to decide if there are any duplicates.
Write a loop over the strings in the provided test_dups list. Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following.
aaa has duplicates
abc has no duplicates
Print a line like one of the above for each of the strings in test_dups.

In the welding operations of a bicycle manufacturer, a bike frame has a long flow time. The set up for the bike frame is a 7 hour long operation. After the setup, the processing takes 6 hour(s). Finally, the bike frame waits in a storage space for 7 hours before sold. Determine the value-added percentage of the flow time for this bike frame. Round your answer to the nearest whole number for percentage and do NOT include the "%" sign in the answer. For example, if your answer is 17.7%, please answer 18. If your answer is 17.4%, please answer 17. No "%" sign. No letter. No symbols. No explanation. Just an integer number.
Answer:
Bike Frame Flow Time
The value-added percentage of the flow time for this bike frame is:
= 46.
Explanation:
a) Data and Calculations:
Bike Frame Flow Time:
Setup time = 7 hours
Processing time = 6 hours
Storage time = 7 hours
Flow time of the bike frame = 13 hours (7 + 6)
Value-added percentage of the flow time for this bike frame = 6/13 * 100
= 46%
b) Flow time represents the amount of time a bicycle frame spends in the manufacturing process from setup to end. It is called the total processing time. Unless there is one path through the process, the flow time equals the length of the longest process path. The storage time is not included in the flow time since it is not a manufacturing process.
