Chapter 9, Problem 1CTQ
Program Plan Intro
Two-factor authentication:
- It is also called as 2FA, which is an extra security layer that is used when logging into websites or applications.
- First, the user has to provide his/ her username and password.
- Second, the user will be provided with another form of authentication method like text message authentication or voice based authentication.
- The three factors that are involved in two-factor authentication include:
- Knowledge
- It is the information that is known to the user like PIN number.
- Possession
- It is nothing but the thing that the user has like an ATM card.
- Inherence
- It is something that the user contains like biometric characteristics.
- Knowledge

C. Homework Assignment
Task: Write a one-page CV using the provided template.
Steps:
1. Use the CV guide to structure your CV.
2. Fill in each section with real information about yourself.
3. Format your CV neatly and use professional language.
4. Submit to the instructor before the next class
Simulate on a vertical time axis (with events labeled with the senders names A-D) the contention period of FOUR equally distanced Ethernet stations that all attempt to transmit at T=0 a minimally sized frame, in the style of the binary Exponential Backoff Algorithm. Assume that time is measured in slot times, and that exactly one slot time is needed to detect a collision (so that if two stations transmit at T=1 and collide, and one of them chooses a backoff time k=0, then that station will transmit again at T=2).
Use as coin flip (source of randomness) an ID written in binary.
use the bits in order from the least significant to the most significant. If for a given coin throw you need k bits, use the least significant ID bit extracted in the corresponding group of bits, as the least significant bit of the coin thrown.
Start be writing the ID, which is 904012207

- Big State University The Big State University course catalog reads as follows: "To enroll in MIS 260, which is an advanced course, a student must complete two prerequisites: MIS 120 and MIS 222. A student who completes either one of these prerequisites and obtains the instructor's permission, however, will be allowed to take MIS 260." Tasks 1. Create a decision table that describes the Big State University course catalog regarding eligibility for MIS 260. Show all possible rules. 2. Simplify the table you just created. Describe the results. 3. Draw a simplified decision tree to represent the Big State University catalog. Describe the results. 4.
