When a c++ program ends with return 0; the process has:
Exited normally
Exited with an error
Exited due to division by 0
Is still running in the background
Was killed by a parent process (process with PID=PPID)
In what case a process can go from ready to blocked?
When a process is not ready to run
When a process needs more resources
When the CPU decides the process needs to sleep
When the OS is blocked
During mutual exclusion
This cannot happen
Interprocess communication issues arise when:
Processes pass information to each other
Processes get into each others way
Processes are dependent on each other
There is a deadlock
Processes fail to load so they block each other
The Operating System cannot schedule processes
Ther eis no dispatcher on the operating system
A critical region is
A shared resource that two processes try to grab
A region that is critical and processes cannot access it
A region that is critical and processes cannot continue running without using it
It is defined as mutual exclusion with busy waiting
A region that can be accessed only through interrupts
A region that can be accessed only by the operating system
What problem the following code causes:
while(true)
{
while(lock==true)
{
use_shared_resource();
release_shared_resource();
}
}
Mutual exclusion with busy waiting
Deadlocks
Its a simplified version of Peterson's Solution
There is an error in the code
It creates a new thread on each while loop
