Sati [7]

Question with options:

What kind of digital certificate is typically used to ensure the authenticity of a web server to a client?

-private

-web server

-public web

-web client

Answer:

Web server digital certificate such as SSL(Secure Sockets Layer) Certificate

Explanation:

Digital certificates are certificates issued by trusted authorities (called Certificate Authority such as Encrypt Certificate Authority) and allow users determine the originality of a resource. With these certificates, users can confirm who the issuer of the certificate is and to whom the certificates are issued. They give users more confidence when using the web.

To determine the authenticity of a web server to a client, a web server digital certificate such as SSL certificate is used.

What is the difference between a master device in a Bluetooth network and a base station in an 802.11 network?

spayn [35]

Answer:

In an 802.11, a master device in a bluetooth network organize themselves into a "Piconet" of up to 8 slave devices. In an 802.11, a base station is a receiver and transmitter that plays a role of the WIFI network.

Explanation:

802.11 is the original wireless specification and it was developed by IEEE. IEEE stands for Institute of Electrical and Electronic Engineers (IEEE).

In an 802.11, a master device in a bluetooth network organize themselves into a "Piconet" of up to 8 slave devices. In an 802.11, a base station is a receiver and transmitter that plays a role of the WIFI network.

Write a program that lists all ways people can line up for a photo (all permutations of a list of strings). The program will rea

irinina [24]

Answer:

Check the explanation

Explanation:

Executable Code:

def all_permutations(permList, nameList):

# Define the function to create a list

# of all the permutations.

def createPermutationsList(nameList):

# Compute and store the length of the list.

n = len(nameList)

# Return an empty list if the size is 0.

if n == 0:

return []

# Return the element if the size is 1.

if n == 1:

return [nameList]

# Create an empty list to store the permutations.

permList = []

# Start the loop to traverse the list.

for i in range(n):

# Store the first element of the current list.

first = nameList[i]

# Compute the store the remaining list.

remaining = nameList[:i] + nameList[i+1:]

# Start the loop and call the function recursively

# with the remaining list.

for perm in createPermutationsList(remaining):

# Append the element in the permutation list.

permList.append([first] + perm)

# Return the permutation list.

return permList

# Call the function to compute the permutation list

# and store the result.

permList = createPermutationsList(nameList)

# Start the loop to display the values.

for perm in permList:

for val in perm:

print(val, end = " ")

print()

# Call the main() function.

if __name__ == "__main__":

# Prompt the user to enter the input.

nameList = input().split(' ')

permList = []

# Call the function to create and output

# the permutations of the list.

all_permutations(permList, nameList)

#endcode

What are the first and the last physical memory addressesaccessible using

Misha Larkins [42]

Answer

For First physical memory address,we add 00000 in segment values.

For Last physical memory address,we add 0FFFF in segment values.

NOTE-For addition of hexadecimal numbers ,you first have to convert it into binary then add them,after this convert back it in hexadecimal.

a)1000

For First physical memory address, we add 00000 in segment value

We add 0 at the least significant bit while calculating.

10000 +00000 = 10000 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

10000 +0FFFF =1FFFF (from note)

b)0FFF

For First physical memory address,we add 00000 in segment value

We add 0 at the least significant bit while calculating.

0FFF0 +00000=0FFF0 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

0FFF0 +0FFFF =1FFEF (from note)

c)0001

For First physical memory address,we add 00000 in segment value

We add 0 at the least significant bit while calculating.

00010 +00000=00010 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

00010 +0FFFF =1000F (from note)

d) E000

For First physical memory address,we add 00000 in segment value

We add 0 at the least significant bit while calculating.

E0000 +00000=E0000 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

E0000 +0FFFF =EFFFF (from note)

e) 1002

For First physical memory address,we add 00000 in segment value

We add 0 at the least significant bit while calculating.

10020 +00000=10020 (from note)

For Last physical memory address,We add 0 at the least significant bit while calculating.

we add 0FFFF in segment value

10020 +0FFFF =2001F (from note)
