Question 1.
What mechanism allows user-space applications to share data directly with the kernel?
Show hintHide hint
Consider how communication happens without data copying.
Question 2.
Which function is used to map shared memory in a user-space application?
Show hintHide hint
This function allows the memory region to be accessible in the application.
3Question 3.
What is shared memory primarily used for?
- File management
- Direct communication between processes
- User interface design
Show hintHide hint
Think about how processes exchange data!
4Question 4.

- True
- False
Show hintHide hint
Consider the efficiency benefits of shared memory.
Question 5.
Design a C program that creates multiple processes, each writing to a shared memory area. Outline the steps and code structure.
Show hintHide hint
Think about creating a scenario with several writers rather than just one.
Question 6.
Explain the consequences of using shared memory without synchronization mechanisms. What might happen?
Show hintHide hint
