Intrusion means unauthorized and harmful activities happening in your system. Any irregularities in the system is considered as intrusion and therefore monitored by administrators and can be detected using Intrusion Detection System.

Examples of Intrusion attacks in a network are:

Denial of Service (Dos) - denial of service means flooding the system causing it to crash and unable to respond to a service request. Normally, a DoS attack is facilitated by numbers of hosts sending enormous request to a victim computer. The requests can be in a form of code that would flood the system and making it to unresponsive.
Man in the Middle Attack (MiM) - a hacker would be in the middle of the communication between a client computer and a server computer. The hacker can mimic IPs within the network and steal information then sends it to the intended receiver.
SQL Injection - For websites that runs database like SQL, a code by the hacker can be added to the website and making him gained access to the database information successfully.

enter a formula in cell b10 to return a value of 35000 if the net profit after tax (cell B() is greater than or equal to 350000

Aliun [14]

Step by step explanation:

Statement to be written in cell B10 :

IF ( B9 >= 350000 , 35000, 1000)

Formula:

IF ( logical_test , [value_if_true] , [value_if_false] )

logical_test = Net Profit After Tax (cell B9)

value_if_true = 35000

(if the Net Profit After Tax (cell B9) is greater than or equal to 350000)

value_if_false = 1000

(if the Net Profit After Tax (cell B9) is lesser than 350000)

In cell F29, use an IF function to display the correct Shipping Charge, based on the amount of the Discounted Total. If the Disc

sladkih [1.3K]

Answer:

= IF(B29 >= B28,0,(0.05 * B29))

Explanation:

Given

Free Shipping Minimum = B28

Shipping Charge = F29

Required

Write a formula in F29 to calculate the total shipping charge based on the condition in the question.

To solve this, the following assumption needs to be made.

It'll be assumed that cell B29 contains the value for Discounted Total.

So,

Discounted Total = B29

The condition in the question says

1. If Discounted Total (B29) is greater than or equal to the Free Shipping Minimum (B29), then Shipping Charge (F29) is 0

This can be represented as

If(B29 >= B28)

F29 = 0

2. Else (i.e. if (1) above is false), Shipping Charge (F29) equals 5% of Discounted Total (B29)

This can also be represented as

F29 = 0.05 * B29

Writing the formula in (1) and (2) together in Excel format;

= IF(B29 >= B28, 0, (0.05 * B29))

The above formula will give the desired result based on the condition in the question.

Take for instance;

Free Shipping Minimum = B28 = 28

Discounted Total = B29 = 30

Since 30 >= 28, the value of F29 will be 0 because it satisfies condition 1.

But if

Free Shipping Minimum = B28 = 30

Discounted Total = B29 = 28

Since 28 < 30, the value of F29 will be 5% of 28 = 1.4 because it satisfies condition 2

san4es73 [151]

Answer:

import re

def country_capita():

#opens file

file=open("inputfile.txt", "r")

dictionary=dict()

#reads line by line

for line in file.readlines():

# substitutes for multiple space a single space

line = re.sub(r"[\s]{2, }", ' ', line)

list=[]

#splits line on space

list=line.split(" ")

#put into dictionary

dictionary[list[1]]=list[2]

# get input

while True:

choice=input("Enter the country name or quit to exit: ")

if choice=="quit":

elif choice in dictionary.keys():

print(dictionary[choice])

else:

print("Invalid Country")

country_capita()

Explanation:

Using python to code this program. First we, (line 1) import the re module which offers us a set of functions that allows us to search a string for a match. ((line 2) Next we define a function country_capita() that will open rawdata_2004.txt, read the information within line by line and create a dictionary list. The we create a while loop with conditional statements that prompt the user to enter country names, print the corresponding values and stops when the user enters quit.
