cs604 GDB solution Operating System fall june 2012

“Suppose a computer lab contains two printers, three tape drives, and four terabyte crystal ROM writers. Assume process 2 is currently using a printer and two crystal ROM writers, process 1 is using a tape drive, and process 3 is using two crystal ROM writers, a tape drive, and a printer.

Suppose now that process 2 requires a tape drive, process 1 requires a printer, and process 3 requires one more crystal ROM writer. Does there exist any safe sequence or not? Give reason/justification to support your answer.”

If you will give invalid reason/justification then you will get zero marks with no leniency. Give reason precisely and briefly to support your comments. The more you will be precise and brief in your comments the more you will get the marks. 

Solution:

Yes there exists safe state.

When all processes take their resources then only one tape drive remained free. Process 2 require 1 tape drive so process 2 gets it. After using it and P2 free all its resources and now P1 Get Printer Resource which is freed by P2. Now Process 3 Used 2 ROM, 2 ROM are already freed by P2. SO we can easily say this that system is in safe state, no deadlock.

Final Project fall spring 2012

Project Title	Multipurpose Viva Exam System (Mobile & Web)
Project Description	This system will provide the facility of entering marks of students in a live environment, such as in viva voce examination. The viva panel members will register through the web interface of the application. Once registered, the panel members can use the application installed on their cell phones, to connect to the main system, and enter marks. This will be handled via bluetooth i.e. the connection between main system and mobile application will be implemented using Bluetooth technology. At the end of viva voce examination, the system will gather all the entered marks and calculate average marks which will be sent to the main system. When the marking will be completed, the web based system will calculate the total marks for student and generate a final marking sheet in PDF or DOC format.
