Case Study 5.0

Q1.) How many different things did you count? What were they? In what ways might computers be used to control things in the supermarket?
A1.) Alarm clock, microwave, car, satellite navigation system, car park barrier, parking sensor, robots in the car making company, automatic door, freezer, conveyer belt, cash register. In the supermarket, computers can control various things from the doors until cash registers (security camera, freezers, conveyer belt, etc); this made things easier to control and less work for th

A2.) Because computer can work better, faster, non-stop, and way more accurate than ourselves. If it fails then the ones controlled by the computer won’t work properly or won’t work at all. The situation might get out of control and this means extra work for cleaning and repairing for the staff. Although, computers are good at making things done in a short term but when it fails we have to cope with the consequences.

Q3.) Describe the inputs and outputs for the other devices that we have talked about so far. How do the supermarket doors and car park barriers know when to open? Identify other control systems that work automatically in this way.

A3.)  

Alarm Clock

Input- set-up the time
Output- the alarm ringing
Microwave

Input- set-up the time, for how long it should cook.
Output- the cooked food, ready to eat!
 The supermarket doors know when to open when the sensor (ray of light) sense movement coming. Another example of this kind of control system is automatic hand dryer.

The car park barriers know when to open when you press the button or you swipe the entrance/exit card. Another example of this kind of control system is the vending machine.


Q4.) What would happen if the instructions were wrong? These instructions assume that the car is in the right place. What would happen if the car were not there? How could they stop this happening?
e staff there.
Q2.) Why is it useful to use computers rather than people to control things? What problems might there be if any of the computer systems fail in the supermarket?

4.0 Case Study

Q1. How could Mussie and Ellie find out whether older people do more for charity than younger people?
A1. Search for the information on the internet, do a survey with people from both side by giving out questionnaires to them.
Q2. Why does Mussie think that these data prove him right? Why might Ellie think that these data do not prove him right?
A2.  1.) Because when he checked one of a charity website, he saw that older people donated more money than younger people so he thinks that he’s right.
        2.) Because the data is only from one of the charity website so it might be different in other charity websites. She also see that the money the younger people are donating is increasing every year while the amount of money donated by older people decreases each year so she thought that if this goes on younger people might donate more. Also it only shows the amount of money people donate, it doesn’t show charity activities since younger people will be doing this more.
Q3.What questions should they ask?
A1. 1.) How old are you?
       2.) How much money do you give to charity?
       3.) How much time do you spend doing charity work?
       4.) What type of charity activities do you do?
       5.) What type of charities you donate money to?

Q4. How many questions should they hand out? Who do you think should fill in their questions?
A4. They should hand out evenly for the younger people and the older people so the result won’t be biased, it depends on the number of people they want to ask. Probably adults and teenagers.     
Q5. Which software could Mussie and Ellie use to put the answer into the computer? How can they check that the data are correct? How could they reduce the number of errors of the data? What problems might there be if the data were typed incorrectly?
A5. 1.)  Microsoft Excel (spreadsheet).
       2.) They can double check the data and write them slowly and carefully.     
       3.)  For preventing errors you can use Spell Check to check the spelling or add validation checks. For
              age you can have ‘range check’ so the computer will check if the age is in the range you gave.
       4.) -You might get the wrong result and it can get confusing since it’s not what you expected.
            - Some of the data won’t be counted.
          
Q6. What is the best way for Ellie and Mussie to present their result?
A6. They can sort their result with a table and then add a suitable chart (pie chart).

Modelling Case Study


1)What might be the differences between a computer system set up for gaming compared to another one set up for gaming compared to one set up for a business to use? Think about the different hardware that might be needed.  Because some customers  want very expensive system that they used for gaming.

2)Earl has got E800 to spend .How can Shaheen work out if he has got enough money ? What if he hasn’t  got
 enough ? What methods could Shaheen use to help her work out the prices of these different options ? She uses a formula to add up the total price of all the items.


3)What does Shaheen  need to do this spreadsheet model so that it ready to use?She need to add some text labels and formats to make it clear.

4)How can Shaheen use the spreadsheet model to help her with the new customer?What changes might she need to make her spreadsheet model? She opens up her spreadsheet model.

5)How else could Shaheen present this information to make it easier to read? She uses another spreadsheet model to keep of how many computer system has she sold.

                                     Loch Ness Monster doesn't exist      http://www.bbc.co.uk/
The team was convinced that such an animal could have survived in the cold waters of Loch Ness, despite the normal preference of marine reptiles for sub-tropical waters. Previous reported sightings of the beast led to speculation that it might be a plesiosaur, a marine reptile which died out with the dinosaurs. Because  they don’t exist in real life.This website is really useful it is from BBc.The Reaschers looked at the habits of modern marine reptiles, such as crocodiles and leatherback turtles,to try to work out how a plesiosaur might have been be behaved.

      2.   How can Remy use the internent to find what he wants?
                    Remy can search from the internent and find the most refinding answer.

      3.Why has Remy got over two million results ?Why are some of the websites he has                                    found not relevant/ how could Remy improve the results?
                    Remy got over million results because when he searches  all the information  are shown in the websites.
Some websites can not be found relevant because everybody can  write their own opinion  in the websites .
Remy can find one suitable website and find the information in there.


     4. Can Remy trust this information? Why might in be unreliable.
              
                    Remy cannot trust this information. It might be unreliable because the writer didn’t say who wrote this.

      5. What software should Remy use? What should he do before he starts using the software.
                    
                    Remy should use word publishing tools. He should check the words and information are correct.

      6. How can Remy design and write the article so that it will appeal to Remy’s readers?
                      Once Remy is happy with the design, he can finshed the articles  on the websites.
