1.) An application software is a software that i nstructs a computer to carry out a specific task. and a language software is something that creates both system and application softwares.
2.) Default setting is when the appilcation software is already installed and it is set up in the way that the sowtware company thinks most people will want. A template is a predesigned file that sets up a structure for a document. Expert System is an application that performs a task that would otherwise be performed by a human expert. Artificial Intelligence is the part of computer science that that is concerned with getting computers behave like humans.
3.) Medicine - to diagnose the illness
Buying and selling of company shares - to choose the best shares to invest in
House buying - to choose the best mortage

1.) examples of highlevel language is Pascal, Visual Basic and Java. These are called high level because they use keywords similar to english and are easier to write than low level languages.
2.) COBOL(Common Buisness - Oriented Language) is a high level language used in buisness programs
3.) The reason why Visual Basic is popular is because it can use predefined libraries of code that can be adapted for their application
4.) A macro is a series of commands that a program can perform automatically. you can use it to sort the class between the surname and the class. To sort out different categories
Pgs. 160-1611
1.) Java is a good computer language because they are able to access any content on the web pages
2.) An applet ensures that everyone can access the web content a small java application.
3.) It is a small piece of software that plugs into larger application to add more features.
4.) The advantage is that the content and layout of a document is preserved

Homework for Tuesday December 2nd 2008
pg. 126-127:
1. Explain what is a computer control system. (3 pts)
2. Give one example of a control system found in the reading and describe how it works. (3 pts)
pg. 128-129:
1. What does a control system consist of? (6 pts)
2. Explain what is meant by embedded controller. (4 pts)
3. Why are control systems considered real-time systems? (3 pts)
4. In your own words explain how control systems have made an impact on our lives. (4 pts)
pg. 130-131:
1. List 6 questions that must be answered when designing a control system. (6 pts)
2. For what purpose would you use a flow chart when designing a control system? (2 pts)
3. Describe two approaches to control programming which most students use. (6pts)
Pg. 126-127
1.) a computer control system is seen everywhere its just that you dont notice. Computer systems do not necessarily posses the features of a regular computer with a monitor and keyboard. A good example of a computer control system is the traffic lights. The control system is all about making the devices do what we want them to do in the right order.
2.) The central heating system is one example. the heat in the system, is generated by the radiators is then fedback to the input of the sensors to stop the rooms from getting too hot.
pg. 128-129
1.) A control system system consists of some sensors which input information, a processing unit(computer) which decides how to respondd to the inputs, and output devices which do what is required.
2.) An embedded controller is the proccessing unit program in electric circuits. They have only one program in their electronics to do the job they were designed to do. It makes them much cheaper to make because they do not need disk storage divices such as a keyboard, a mouse or a screen.
3.) They are known as real-time systems because they rely on the enviornmental feedback in order to work and get their job done. They need to be able to respond quickly to the current conditions as described by the sensors and to let the processing unit take the appropriate action.
4.) I think that the control systems have impacted our lives. People lost their jobs but at the same time machines were made and now rather than doing the repetitive tasks themselves they now keep running machinery. the speed and effiency of the machines are higher.
pg.130-131
1.) the 6 questions are
-What need to be done?
-What outputs are required from the system?
-Which output devices do you use?
-How many devices do you need?
-Which sensors do you use?
- what will the system need to know about what is going on so that it can make sensible decisions about what to make the output devices do
2.) You will use a flow chart for the visual approach. You will build your working ansewwr by constructing a flow chart. These commands may set the pattern of ons and offs you want on the outpput. Also to instruct the computer to look aat sensor to see what is happening or to make some decisions based on what it had just found out about the state of the system.
3.) there is the visual apporoach and the others use a programming language. These often work like the LOGO programming. The have words or commands that make the computer to do particular thingss. they also let you build procedures(functional blocks of programming which can then be linked together to create a larger, more complex control program sequence)
