Answer:

Decrease file size

Explanation:

This goes for almost every file you compress. If you compress it, you try to decrease the storage space it takes up as a way to make it more portable. After a compressed file is extracted, it does not have many effects on the state of the extracted file.

To deny a host from sending HTTP traffic destined to a specific server you will need to apply a __________ Access Control List.

DedPeter [7]

I would a Standard Access control List

There are two common access lists: The standard and extended access list. With the standard access list, it creates filters only on source addresses and is commonly used for server-based filtering. They are not as powerful as extended access lists. Standard Access lists are typically used for restricting access to a router through HTTP and HTTPS.

vampirchik [111]

Answer:

This exercise includes the following question and options:

What is the logical error in the coded query?

A) The condition in the WHERE clause should be coded in the HAVING clause.

B) The column name for the fifth column in the result set doesn't match the data.

C) The three columns in the ORDER BY clause should use the DESC keyword so the city totals will be in the right sequence.

D) The condition in the HAVING clause should be coded in the WHERE clause.

And from the options provided, the error is in the 5th column, due to the column name in that result series/group doesn't really coincide with the data, thereby the correct option is B).

Write a function called 'game_of_eights()' that accepts a list of numbers as an argument and then returns 'True' if two consecut

MrRa [10]

Answer:

In Python:

def main():

n = int(input("List items: "))

mylist = []

for i in range(n):

listitem = input(", ")

if listitem.isdecimal() == True:

mylist.append(int(listitem))

else:

mylist.append(listitem)

print(game_of_eights(mylist))

def game_of_eights(mylist):

retVal = "False"

intOnly = True

for i in range(len(mylist)):

if isinstance(mylist[i],int) == False:

intOnly=False

retVal = "Please, enter only integers"

if(intOnly == True):

for i in range(len(mylist)-1):

if mylist[i] == 8 and mylist[i+1]==8:

retVal = "True"

break

return retVal

if __name__ == "__main__":

main()

Explanation:

The main begins here

def main():

This gets the number of list items from the user

n = int(input("List items: "))

This declares an empty list

mylist = []

This iterates through the number of list items

for i in range(n):

This gets input for each list item, separated by comma

listitem = input(", ")

Checks for string and integer input before inserting item into the list

if listitem.isdecimal() == True:

mylist.append(int(listitem))

else:

mylist.append(listitem)

This calls the game_of_eights function

print(game_of_eights(mylist))

The game_of_eights function begins here

def game_of_eights(mylist):

This initializes the return value to false

retVal = "False"

This initializes a boolean variable to true

intOnly = True

This following iteration checks if the list contains integers only

for i in range(len(mylist)):

If no, the boolean variable is set to false and the return value is set to "integer only"

if isinstance(mylist[i],int) == False:

intOnly=False

retVal = "Please, enter only integers"

This is executed if the integer contains only integers

if(intOnly == True):

Iterate through the list

for i in range(len(mylist)-1):

If consecutive 8's is found, update the return variable to True

if mylist[i] == 8 and mylist[i+1]==8:

retVal = "True"

break

This returns either True, False or Integer only

return retVal

This calls the main method

if __name__ == "__main__":

main()
