Discuss the differences between a quantitative and qualitative risk analysis. Please write two paragraphs.

Burka [1]

Answer:We start each project to get some business benefits. We design it to achieve users and other stakeholder’s satisfaction. And we build it to improve organization KPIs. But, we live in a world where the project faces many uncertainties. These uncertainties or risks can prevent from achieving our project goals or objectives. So, it is critical that we identify them in time to take care of their effective responses.

The more we know our risks, the more we can evaluate and prioritize them timely for:

Reducing their probable negative impacts, or

Increase their likely positive impacts

We can use Qualitative Risk Analysis and Quantitative Risk Analysis techniques to evaluate and prioritize risks. I see there are a lot of confusions around how these two techniques are different from each other. In this blog, I will address these confusions and differences between these two techniques.

Before we get into the difference between qualitative and quantitative risk analysis/assessment, it is mandatory to understand how we perform risk analysis in projects. Below is the summarized demonstration of the risk analysis:

Three PCs are on an Ethernet LAN, connected by a hub. Describe how the Ethernet protocol deals with collisions in this situation

sdas [7]

Answer:

All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.

A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision

Explanation:

Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.

CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.

1. Your task is to process a file containing the text of a book available as a file as follows:A function GetGoing(filename) tha

Irina18 [472]

Answer:

See explaination

Explanation:

#function to count number of characters, words in a given file and returns a list of words

def GetGoing(filename):

file = open(filename)

numbrOfCharacters =0

numberOfWords = 0

WordList = []

#iterate over file line by line

for line in file:

#split the line into words

words = line.strip().split()

#add counn of words to numberOfWords

numberOfWords = numberOfWords + len(words)

#find number of characters in each word and add it to numbrOfCharacters

numbrOfCharacters = numbrOfCharacters + sum(len(word) for word in words)

#append each word from a line to WordList

for word in words:

WordList.append(word)

#display the result

print("The number of characters: ", numbrOfCharacters)

print("The number of Words: ", numberOfWords)

#return the list of words

return WordList

#find matches for keywords given in textlist

def FindMatches(keywordlist, textlist):

for keyword in keywordlist:

keyword = keyword.lower()

print ("The number of occurrences of {} is: {}".format(keyword,len([i for i, s in enumerate(textlist) if s == keyword])))

#main

booktext = GetGoing("constitution.txt")

FindMatches (['War', 'Peace', 'Power'], booktext)
