The Critical section problem occurs when the processors are in a Network. For eg consider that 3 processors share same database at a time, if one processor wants to update the database then no other process will get the access to that database. This point is called as critical section. Temporarily the connection between the other 2 system will be dropped.
in an operating system, there may be a segment of code, which will be shared by many processes.but when two processes shares the code and if one updates the code while other reading it,there occurs a conflict.this is called critical section problem
To avoid this problem a lock is created on that block of code which establishes that no new process can access that block until the first process release it after it's usage.
Thus there would be no chance conflict b/w processes while reading that block simultaneously

Difference between critical and non critical task in real time system?
the difference in critical and non critical task in a system is critical task are processes that the computer needs to operate correctly they are must have programs. Non critical talk are task that are running or can run but is not a crusial part if the task is deleted or ended then the OS should still fuction properly

Shared data problem in embedded system?
if a variable is used by multiple tasks or processes, conflict arises.the variable value will become inconsistent. solutions are to disable interrupts when critical region starts execution, using semaphores.
Why when your computer opens up spiral knights it says that there is a problem?
Try asking the GMs/developers of spiral Knights, either by choosing an option from the Spiral Knights support portal (see Sources and Related Links further down this page) or by checking the 'Technical issues' Section of the forums to see if your problem is there.

What is distributed mutual exclusion?
distributed Mutual exclusion, in computer science, refers to the problem of ensuring that no two processes or threads (henceforth referred to only as processes) can be in their critical section at the same time. Here, a critical section refers to a period of time when the process accesses a shared resource, such as shared memory. The problem of mutual exclusion was first identified and solved by Edsger W. Dijkstra in his seminal 1965 paper titled: Solution of a problem in concurrent programming control..hope it helps:)
