Why should race conditions be avoided?

Race condition is a dangerous state of an electronic system because it can destroy the whole process.  Race condition or also called race hazard happens when the result of a certain output depends on the timing of other events.  This may happen unexpectedly that’s why it must be avoided because it can destroy the whole electronic system and it can also cause security problems.

The term race condition was coined because it refers to two signals racing each other to manipulate the output.  This may take place in computer software or electronic systems which are poorly designed.

Then a programmer assumes incorrectly the timing of a particular event, then there is a possibility that race condition may arise.  Some of the factors that contribute to race condition are the signals, checking access, and opening of files. For programmers who are less skilled and inexperienced, this usually happens.

Race condition must be avoided because it will affect the outputs especially in electronics.  Since an output depends on the input, there will be a sudden change of state if race condition occurs.  This will cause the delay on the process.  This will make the system erroneous and sometimes, can cause a permanent error in the system.

In computing, race condition must be avoided because it causes the pattern to be distorted.  There is a big possibility that this hazard will exist if there is communication between separate threads of execution or processes. This will cause files to be shared by others and some files to be unorganized.  If race condition exists, security of files becomes a great trouble.

To avoid race condition, proper design techniques must be applied before it becomes a great problem.  Files and process must be created correctly, handle races in the file system properly, and have your signals used safely.
