reflection of the year

I learn how technology use in different softwork. and I think that the softworks is very useful. Microsoftwork is use for typing documents, microsoft excel is for entering results from data, micrpsoft powerpoint is for presentation. I think that microsoft excel is very good, cause when we enter the formula of the results, It will do the calculatiion for us. I think the questionnaire task is very good, I can learn how to create questionnaire, and we actually give out the questionnaire and get back the questionnaire, I have lots of fun with that task.

Case study- module 5

Q1. How many different things did you count? What were they? In what ways might com-uters be used to control different things in the supermarket?

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?


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.

Q4. What would happen if the instructions were wrong? These instructions assume that the car is in the right place? What would hap-pen if the car were not there? How could they stop this happening?

Answers:

A1. Microwave , car , satellite navigation system , Car park barriers , parking sensors , Robots.  In supermarkets the doors, freezer, conveyer belt, cash register.

A2. Because computers work way faster and can be programmed depending on people’s needs. If the computers system fails, the supermarket won’t operate properly and the staff cannot control the system.

A3. I think there is camera to see when pupils come and cars come . The cleaning head liguid machine does that automatically, When we put our hands near the camera, the liguid will automatically comes out.

A4.I think the robot will do a wrong thing and broke the screen of the car. I ithnk the pupils should change the instructions of the robot, like enter the right instructions.
