Consider an e-commerce Web site that normally runs seven days a week, 24 hours a day, generating an average of $10,000 per hour in revenue from customer orders. Experience has shown that:
- the site becomes unavailable due to operating systems failure five times a week.
- At each operating system failure, the site is unavailable for 2 hours.
- In addition, the company estimates that upon a failure, it would spend $5,000 on advertising to counteract the negative publicity from such an incident.
Calculate SLE, ARO and ALE (Show the calculation).
Case Study:Consider an online shopping website that maintains a shopping cart. A user can search productsand place order and can make payment for it either online or cash on delivery. If a user placean order of amount RS 2500 or above he gets home delivery of the product for free, otherwisehe has to pay Rs 250 extra for home delivery. There are different types of users based onmembership Guest User (No membership), Gold User, Platinum User. Guest user doesn’t getany discount, Gold user gets 5% off on every product, Platinum User get 7.5% on everyproduct.

- Suppose a business person launches new cinema at Islamabad and ask his team to develop a ticket system for box office. He assigns some requirements about system that how should it work. The requirements are such a way that there are only '5' number of box office windows in the theatre. Each window can have at max '20' number of people waiting in line. To start with, only one window is opened. If the number of people waiting in line in that window exceeds 20, then the next window is opened and people can join the line in that window. Likewise, if both the first and second windows have n number of people waiting in each queue, then a third window is opened. This can go on until the maximum number of windows w is reached. Let us assume that once a window is opened it never closes. A new window is only opened if all open windows are full. Each person can buy only one ticket. So, the system should not allot more than one ticket per person. Let us assume that the system issues one ticket…arrow_forwardHow many of the following three conditions must be satisfied before we can call a network productive and successful?

- Suppose you have to select one project partner from a set of four classmates, who have different GPAs. Assume you do not know any student’s GPA in advance but can get to know it after you have picked a student from that group (a) Suppose you pick one of the four students at random and accept that student as your project partner. What is the probability that your partner is the one with the highest GPA? (b) Suppose you decide to reject the first student and to then accept the next student if and only if that student has a higher GPA. Note that you MUST have a partner, so if the first three are rejected by you, then you have to accept the fourth student. What is the probability that your partner will be the one with the highest GPA.arrow_forwardSuppose you open a small shop and can't pay electronically. There are only four kinds of coins in the cashbox: 25 cents, 10 cents, 5 cents and 1 cent. If you are a salesperson and want to change 41 cents for customers, how can you arrange to give customers the right amount of money and the least number of coins? The idea:Take the coin with largest denomination without exceeding the remaining amount of cents, make the locally best choice at each step.arrow_forwardSuppose you are going to simulate GPS positioning using 4 satellites. You are going to pretend to be a GPS receiver somewhere on the map and will figure out where you are based on the 4 “signals” you receive. But for you (and for a GPS receiver) all those signals tell you is where the satellite was when it sent the signal, and how long it took for the signal to get from the satellite to you. You need to determine where you could be (Mention distance in terms of grunters chain), based on that amount of time elapsed. The speed of light (R) is 299,792,458 m / s. You need to account for the scale factor of the map. This map has a scale factor of 1:21,283,839. This means that 1 meter on the map equals 21,283,839 meters on the earth’s surface. A = .00415783 seconds B = .00400006 seconds C = .00837010 seconds D = .00712225 secondsarrow_forward
- Which three characteristics are necessary for a network to perform optimally?There was a pause for a split second.arrow_forwardIn addition to being a Computer Scientist, you have a (side-hustle) business where you sell flower bouquets.Each of your flower bouquets consists of a certain number of red roses, with a minimum of 1 and a maximum of 6. This is the profit you make from each of your bouquets, which is a function of the number of red roses in that bouquet. You have 6 roses with you, and now you need to decide what bouquets to make in order to maximize your profit. I have presented this data as a set of tuples below. (Roses, Prices) = {(1,$3),(2,$5), (3, $9), (4,$13), (5,$14), (6,$18)} For example, if you make two 2-rose bouquets and two 1-rose bouquets (2+2+1+1=6), then your profit is 5+5+3+3=16 dollars. Note- for this problem you can have multiple rose bouquets in each category. However, if you make a 5-rose bouquet and a 1-rose bouquet (5+1=6), then your profit is 14+3=17 dollars. Determine the maximum profit you can make.arrow_forwardThe following scenario is used for Case Projects 2-1 through 2-6: Darts is a sporting goods company with outlets in most of the western states.

The new chief financial officer believes that the Windows 7 computers should not be upgraded. In his opinion, "If it works, don't fix it." What is your response?arrow_forward
