Solution# 1

(A):     A system has three basic elements input, processing and output. The other elements include control, feedback, boundaries, environment and interfaces.

Task: Attempt quiz 1. Input: Input is what data the system receives to produce a certain output. Example: After successful login ,student can go to subject section and will click on “submit quiz “ option.

 2. Output: What goes out from the system after being processed is known as Output Example: System will show the quiz page to the students.

 3. Processing: The process involved to transform input into output is known as Processing. Example: System will Process the input and navigate the student to another page.

 4. Control: In order to get the desired results it is essential to monitor and control the input, Processing and the output of the system. This job is done by the control. Example: Quiz has a timers control mechanism will automatically handle the time of each question, once the time will end ,system will move toward next question ,until and unless user will not press the “next “button.

 5. Feedback: The Output is checked with the desired standards of the output set and the necessary steps are taken for achieving the output as per the standards, this process is called as Feedback. It helps to achieve a much better control in the system. Example: After attempting the quiz system will give you feedback by saying that you have successfully attempt the quiz.

 6. Objective: The boundaries are nothing but the limit of the system. Setting up boundaries helps for better concentration of the actives carried in the system. Example: The expected results are gained like student attempted the quiz and system performed as expected.

 7. Environment: The things outside the boundary of the system are known as environment. Change in the environment affects the working of the system. Example: Our internet system,electercity both come in our environment. If Our internet system is not good and light is off during quiz time ,we are unable to attempt it.

 8. Interfaces: The interconnections and the interactions between the sub-systems is known as the Interfaces. They may be inputs and outputs of the systems. Example: All students uses LMS system for attempting quiz.

 (B) :     1. Closed Loop system: “A closed loop control system considers the current output and alters it to the desired condition. The control action in these systems is based on the output.” If LMS will be closed loop system it should have input, output,control,feedback and objectives. Feedback is the major points which differentiate closed loop system from open loop system. Input: Login into LMS system: Output: Either successful or fail login. Control mechanism: Control the login attempt after that blocked the LMS account or Control the schedule of assignment and quizzes (after due date submit option will automatically disappear). Feedback: The output of the system depends on the input. If student will enter something wrong system will send an alert. Objectives: LMS as an closed loop system should generate the expected result. Environment: Our internet should be good and there is no light issues for attempting quiz. Interfaces: All students uses LMS system for attempting quiz.

 2. Open Loop system: An open loop control system acts completely on the basis of input and the output has no effect on the control action. LMS as an open loop system should require three components input, process and output. 1. Input can be: Student can able to open the assignments upload /quiz attempt links. User can able to view the marks. 2. Process can be: System processes the information either the user is authorized or not. System should upload the assignment file and check the format of the file.

 3. Output can be: System will show the message that assignment is uploaded successfully.
