Reflection

In ICT we have learned how to use Powerpoint in detail, planning the presentations. We also learned how to use Excel and include validations, also we learned how to sort and search. In Word we learned to create questionnaires and create flowcharts.

I have learned a lot in ICT and I am very happy about this year!!!!!!

Thank you Miss Kavitha for your patience while teaching us so many new things about computer tecnology, I appreciate your efforts to teaching our class, you were a great help and made ICT great :)

Canteen Questionnaire Hypothesis and Conclusion

For ICT, Module 4 we did a mini project on canteen food. We made our own canteen questionnaire. I am now presenting the hypothesis and showing the conclusion. These are pictures of the slides related to the hypothesis and conclusion.

Hypothesis



Conclusion

My hypothesis (a prediction at the beginning of the questionnaire that I test using a questionnaire and see if it is true or false) was that "Canteen lunch is more popular than other lunch".

The conclusion (the fact that I find out after recieving all the questionnaires, entering the data into Excel and checking it against the hypothesis) was that "Canteen lunch is more popular than other lunch", which proves the hypothesis was true.

We have now finished the project, I would like to thank everyone who helped fill in this questionnaire.


:) Thank you :)

Case Study 5 by Eagles

1)    How many different things did you count? What were they? In what ways might computers be used to control different things in the supermarket?

Four things. They were the security sensor, key card, elevator and the CCTV. The computer system will sense this stuff.

2)  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?

Humans need rests but computers can work for the whole day automatically. Problems could be that there are wrong temperatures in the freezers and food has the wrong temperature too.

3)   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.The supermarket doors will know to open when it senses a person or obstacle in front of it. A car park barrier knows to open when someone pushes the button or when a car comes close to it. Car systems that sense when cars park or GPS systems work the same way.

4)  What would happen if the instructions were wrong? These instructions assume that the car is in the right place? How could they stop this happening?
They could put a loop in the instructions so that if there is not a car, the system senses it and stops.

Case Study 4 Data Handling

This case study was made by Group 1 Eagles (Andy = questions 1,2,3 ; Charlotte = questions 4,5,6)

Case Study 3 Modelling

Q1 What might be the differences between a computer system set up for gaming compared to one set up for a business to use? Think about the different hardware that might be needed.


A1 A computer system for gaming would be more expensive but also more powerful. Why? Because they need to run high tech computer games that require speed and a large memory. There would be a large screen (better for the eyes), a High speed CPU or Tower with a lot of RAM and ROM and the latest system, a DVD drive, a High speed modem and loud speakers.
A system for a business would be less expensive because office ladies don't need so much speed. They would only need a large screen (better for the eyes), a normal CPU with a modern but quite basic system and a printer.


Q2 Earl has got £800 to spend. How can Shaheen work out if he has got enough money? What if he doesn't have enough? What methods could Shaeen use to help her work out the prices of these different options?


A2 She can use a Excel worksheet and the "Sum" option. then enter the prices in and calculate. If he doesn't have enough money Shaheen can find him some cheaper options. She can also make a price list or spreadsheet page to find out the prices of different choices. 


Q3 What does Shaheen need to do to this spreadsheet model so that it is ready to use? 


A3 She needs to add the formulas of how much the customer has to spend and to work out whether the customer has got enough money.


Q4 How can Shaheen use the spreadsheet model to help her with the new customer? What changes might she need to make to her spreadsheet model? 


A4 She could show the spreadsheet to the customer and tell him the prices of the other choices.. Then the new customer can choose which option he wants to buy.


Q5 How else could Shaheen present this information to make it easier to read?


A5 She could use a bar graph or chart to make it easier to read.
