SOLVE STEP BY STEP PLEASE THANKS! A website password is made up of 8 characters, of which at least 2 must be letters (uppercase or lowercase, assume there are 26 of each), at least 2 must be decimal digits (0 to 9) and at least 2 must be special characters (assume there are 24 special characters). In how many ways can the password be chosen if repeating characters is allowed and it is case sensitive?

Heading 1 Heading 2 Heading 3 Heading 4 Paragraph Styles Turtle Graphics is a Python feature like a drawing board, which lets us command a turtle to draw all over it! We can use functions like forward(...) and right(...) which can move the turtle around. Commonly used turtle methods are found in the posted pdf file "turtle - Turtle graphics - Python 3.7.1rc1 documentation" Г To make use of the turtle methods and functionalities, we need to import turtle. "turtle" comes packed with the standard Python package and need not be installed externally. The roadmap for executing a turtle program follows 3 steps: 1. Import the turtle module 2. Create a turtle to control. 3. Draw around using the turtle methods.

Denial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $10,000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $6,000. The cost of implementing these controls is $12,000 a year. From a purely financial point of view, is it worth for the company to implement these controls? O None of the these Yes, because the measures will save the company $2,000. ONo, because the measures will cost the company $2,000. No, because the measures will cost the company $4,000. Yes, because the measures will save the company save $14,000.
3. Students are required to create 6-character long passwords to access the library. The letters must be from lowercase letters or digits. Each password must start with "a" or "b", it also must contain at most three lowercase- letters (including the first letter) and contains no repeated digits (letters can be repeated). How many valid passwords are there? You are required to show your work step-by-step. [10 marks] 10 points
HackerLand National Bank has a simple policy for warning clients about possiblefraudulent account activity. If the amount spent by a client on a particular day is greaterthan or equal to 2 ×the client's medianspending for the last d days, they send the client a notification about potential fraud. The bank doesn't send the client any notificationsuntil they have at least d prior days of transaction data.Given the value of d and a client's total daily expenditures for a period of n days (where n>d) write amethod which returns the number of times the client will receive a notification over all days.Note: Your algorithm time efficiency should not exceed O(nd) where n is the total number of daily expenditures and d is the number of prior day expenditures used for frauddetection.Your algorithm space complexity should not exceed O(n+d).where n is the total number of daily expenditures and d is the number of prior day expenditures used for frauddetection.Space complexity is defined as the…
Bob has designed a secure login system for the student portal of the Xiamen University of Technology (XUT). In Bob's design, a two-factor authentication method is used for verifying the authenticity of the user. A brief description of the design is provided below. For the two-factor authentication, the followings are required: • Factor 1: a user first required to provide a secret password, • Factor 2: the user then needs to provide the correct answer to a security question. To securely store the user password in the system, Bob has used state-of-the-art encryption algorithm, Advanced Encryption Standard (AES), to encrypt the user password and stored the encrypted password in the system database. For securely signing in to the system: the user needs to provide his/her user ID and the corresponding password. This information will be transmitted to the system over a secure communication channel. Upon receiving this information, the system will: o locate/retrieve the corresponding…
The - method has a parameter, amount, that is a double. When the method is called, the amount that is to be withdrawn from the account is passed into this parameter. The value of the parameter is then subtracted from the value in the balance field. The method multiplies the interestRate field by the balance field to determine the monthly interest for the account. The amount of interest is assigned to the interest field and added to the value in the balance field. Choose... Choose...
A SAF authorization form is used in most universities to approve funding for students to aid their studies. Suppose a student fills out a blank form and sends it to his or her departmental chairperson for a signature. If the amount of funds requested by the student is small (under 10,000 Tk), then the chairperson signs the form and routes it to accounts payable to be input into the accounting system. The system cuts a check that is sent to the student for the right amount, and after the check is cashed, the form is filed away with the canceled check. If the check is not cashed within 30 days, the form expires. When the amount of the requested fund is large (over 10,000 Tk), the chairperson signs the form and sends it to the chief financial officer along with a paragraph explaining the reason for the grant, and the chief financial officer will sign the form and pass it along to accounts payable. Both the chairperson and the chief financial officer can reject the SAF authorization form…

CS 386 Project: Overview Project Synopsis: This group project will require your group to design and implement your own enciphering algorithm. Your team's algorithm must combine the two operations, substitution and permutation/transposition, into your unique encryption algorithm. Your encryption algorithm must include multiple rounds of the two operations. You program must be able to encrypt and decrypt messages. Your team will need to give your algorithm a name that is unique to your encryption technique. Your group may
What is the difference between a binary semaphore and a counting semaphore? Question 9 options: A binary semaphore is used for mutual exclusion, while a counting semaphore is used for synchronization. A binary semaphore can only take two values, while a counting semaphore can take any positive integer value. There is no difference between a binary semaphore and a counting semaphore. A binary semaphore is used for synchronization, while a counting semaphore is used for mutual exclusion.
