I studied many things in ICT in this year: chapter 2, chapter 3, chapter 4 and chapter 5. My favourite chapter was chapter 4 because I made my first and own questionnaire ti distribute to my classmates and teachers. Ms.Kavitha is a really good and challenging teacher, serious but not bad. She teached us and then, when we finished the whole chapter, we would do a test based on the whole chapter.
The interesting thing about this chapter is that you can find out all the difficult thing in the computer and about it. I liked the year with Ms.Kavitha and i need to say 'THANK YOU' to her, she let me discover a lot of things!!!

Case study 5
Q1. How many different things did you count? What were they? In what ways might computers be used to control different things in the supermarket?
A1.10 different things. They are the microwave, GPS, gas fill up, car park barrier, Car reverse sensor that goes beep, robot, automatic door, freezer, conveyer belt, pays with the card. The computer controls the air conditioner, the fans, the freezer, the lights, the conveyer belt, barcode sensor, automatic doors and the room temperature.
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. If we use people to control the machines then it will be slower and it is too much for them to control. People will wait for a very long time to get their turn in line.
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. Microwave’s input is set the time and output is cook food,Alarm clock’s input is set the time and output is alarm on, Car barriers’ input is swap the card or punch the button, and output is open the door, Supermarket door’s input is move to the door and output is open the door.
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.If the instrument were wrong , the robot will drop the wind shield and broke it. If the car was not there the robot will automatically stop. They stop this happen by stop the mechine.

Q5:Which software could Mussie and Ellie use to put the answers into the computer? How can they check that the data are correct? How could they reduce the number of errors in the data? What problems might be there be if the data were typed in incorrectly?
A5:They should use Microsoft Excel (spreadsheet). They can check if the data are correct with formulas so that the calculations are right. They can refuse the number of errors writing properly and carefully. They might come to the wrong conclusion when they look at the data.
