5.0 Case study

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 the 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?

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?

A4.)The robots will just follow the instructions without knowing it’s wrong or not. The windscreens will probably drop and break because the car isn’t there to place the windscreen. To stop this from happening it need the right instructions, like instructed to stop or put down where it was if there’s no car there so that no windscreen will be wasted.

ICT 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).

3.0 Modelling, Homework

Justin Chen Homework.

Q: What might be the differnences between a computer system set up for gaming compared to one set up for a business to use?

1. The gaming computer would be a lot faster for Frame Per Second (FPS) rate. So if your gonna use a gaming computer you will need a good and high quality poccessor .The business computer will not be as fast as the FPS rate of the gaming computer and you will just need a medium pocessor instead since your not gonna use it for gaming. ( He needs a faster processor.)

Nessie Monster - Justin chen

                                                       Nessie Monster

[Nessie Exists] :

There was recently proof that the Nessie monster exists with the proof at Google Map. A man called Jason Cooke spotted the Nessie monster at Scotland. The shape of the Nessie was large.

Here is a picture of the Nessie monster.

[Nessie Does Not Exists]:

Nessie does not exists because there is no official proof that was caught on video. Most of them are probrally hoax’s. Also people never actually seen it. As you seen the picture above this text is just a picture and not a video. It could have been edit’ed and put one. Since it was on news maybe it was real. But who knows it could just be a giant fish.
