15. How does `pthread_create()` facilitate parallel processing
pthread_create() is frequently used in situations where task is divided into smaller units that run in parallel,such as multi-thread applications like web server where multiple clients request need to be handled concurrently.

some use cases where …

7. Describe the advantages of using Pthreads over processes in developing concurrent programs.
Advantage of pthread over process

1)Improved performance:by splitting task into multi threads,program can take advantage of multi core processor and executes task in parallel

2)Memory efficiency thread share the same memory space ,they are more me…

8. Explain the function and usage of `pthread_join()` and how it helps in thread synchronization.
pthread_join() function is used by one thread to wait for another thread to finish execution. when pthread_join is executes the calling thread goes into block states until created thread terminates and executes pthread_exit () call,the created threa…

5. What is the significance of thread states like running, blocked, and waiting
Thread can exits in various states during its lifetime.These states include:

1)RUNNABLE:Thread is creted and is waiting for execution or its cpu cycle.2)RUNNING:The thread is actively executing its assigned function.3)WAITING:Thread is waiting for …

9. How does shared memory between threads in Pthreads simplify communication compared to processes?
In multi-threading program ,all thread shares same memory space including data segments,file descriptor table and memory mappings.This means thread can directly access and modify shared variable making communication easier by eliminating the need of…

6. What challenges are commonly associated with using Pthreads, such as race conditions and deadlock
challenges commonly associated with Pthreads :

RACE CONDITIONS:When multiple Threads access and modify shared data without proper synchronization,it can lead to inconsistent results.

DEADLOCK: If two or more threads are waiting indefinitely for re…
