[IB Computer Science Student Organization: Operation upgrade]

Students have agreed to meet every Wednesday after school to put in extra work on their IA's and others related to IB Computer Science in order to improve overall standing in the course.

[HL Student presentations] Starts Feb 4, 2014, Tuesday Day 2

Discuss a range of control systems. A variety of control systems should be examined such as automatic doors, heating systems, taxi meters, elevators, washing machines, process control, device drivers, domestic robots, GPS systems, traffic lights and other common devices. Technical knowledge of specific systems is not expected but students should be able to analyse a specified system.

Outline the uses of microprocessors and sensor input in control systems. These should be related to the examples suggested above.

Evaluate different input devices for the collection of data in specified situations. Scenarios will be based on familiar situations to students.

Explain the relationship between a sensor, the processor and an output transducer. Technical hardware details are not expected.

Describe the role of feedback in a control system.

Discuss the social impacts and ethical considerations associated with the use of embedded systems. For example, tagging prisoners, surveillance, CCTV, improved safety systems.

Compare a centrally controlled system with a distributed system. Technical hardware details are not expected.

Outline the role of autonomous agents acting within a larger system. Technical hardware details are not expected.

Terms:

A Control System is an organization of parts that when connected together influences or modifies a process. Automated control systems are used for efficiency, accuracy and reliability. E.g. in controlling the heating of water, a sensor is used to determine the temperature, a controller is used to control and compute then issue a command to a control element that does the actual task such as closing a valve or lowering the thermostat.

Tips in Taking the Exam

• • • Take a few seconds to scan the whole paper at the start of the exam

    • When answering, look at the action verbs and the number of marks required first

    • Generally, the number of marks correspond to the number of sentences or ideas

    • Be an expert - Use the proper terminology - Don't shoot yourself in the foot!

    • Give examples to help you get the full mark

Tips in Studying for the Exam

• • • Read the ebook and other documents

    • Practice using terminologies

    • Practice making pseudocodes, flowcharts and trace tables
