DIA [1.3K]3 years ago
7 0

The <em>cloud bleed vuneraliblity</em> describes the security flaw which was discovered in 2017 and had affected internet service company CloudFlare and many websites using the company's services.

CloudFlare is a internet service company which operates to provide security of data to millions of websites. However, a glitch occured during a certain security update which led to a loophole which wasn't discovered for months.

This made the user data on CloudFlare's network susceptible over the course of that period. It was reported that companies such as Uber, OKcupid and several others on the CloudFlare security network were affected.

Therefore, the company affected by the cloud bleed vuneraliblity is CloudFlare.

The birthday problem is as follows: given a group of n people in a room, what is the probability that two or more of them have t
Julli [10]

Answer:

import random

def calc_birthday_probability(num_people):

   num_tries = 1e6

   num_duplicates = 0

   tries = 0

   while tries < num_tries:

       total_birthday = {}

       for i in range(1, 366):

           total_birthday[i] = 0

       for count in range(num_people):

           birthday = random.randint(1, 365)

           if total_birthday[birthday] != 0:

               num_duplicates += 1

               break

           total_birthday[birthday] += 1

       tries += 1

   return num_duplicates/num_tries

def main():

   num_people = 10

   p = calc_birthday_probability (num_people)

   print(p)

   num_people = 20

   p = calc_birthday_probability (num_people)

   print(p)

   return

if __name__ == "__main__":

   random.seed(2020)

   main()

Explanation:

  • Run the loop until the value of tries is less than num_tries to do number of trials.
  • Run the loop to create the desired number of birthdays by generating random numbers.
  • Increase  the num_duplicates  variable by 1, if the birthday has  already occurred.
  • Lastly define and then call the main function.

How does polling-based network receive work? How is it different than interrupt based network? Describe both functions and list
Alenkasestr [34]

In a polling-based network receives, the operating system keeps checking the status register after a fixed time interval to see whether a device needs hardware attention or not. CPU gradually checks the status of receive bit after a defined time interval of a clock and if the value of receive bit is true then data is moved from the RX register to the memory. In interrupt-based networks, whenever a device needs hardware processing then an interrupt is raised to inform the CPU for device attention. The data of the device is transferred to memory from the network card.

Polling is a protocol, not a hardware mechanism where the device gets attention by CPU. An interrupt is a hardware mechanism, not a protocol where the device gets attention by the interrupt handler. In polling, during receiving, parts of received data need to transfer to memory but in case of interrupts, whole data is transferred at once after receiving is done. An interrupt is a heavy operation as compared to pooling because hardware involves in it. For large amounts of data, Polling becomes an inefficient method. In polling, CPU gradually checks devices at regular intervals whereas the Interrupt handler can send interrupt at any time. Each device has its own Command ready bit which indicates whether the device requires servicing or not. In polling, CPU wastes numerous clock cycles by repetitively checking the command-ready little bit of each device. In Interrupt based network, the interrupt request line indicates whether the device requires servicing or not. In interrupt-based network, CPU cycles not wasted but CPU is disturbed only when device send interrupt signals.  

Relative performance between programmed I/O and DMA:

For determining the relative performance between programmed I/O and DMA, important factors are:

1. Size of data  

2. Frequency of operations
