Easy example: two threads in one process are trying to update the value of a variable at the same time. This is bad juju lol. As a programmer, you need to ensure order by protecting that variable with a synchronization object. A beastie called a mutex. To update the variable, a thread must first acquire ownership of the mutex, then update the variable, then release the mutex. While the mutex is owned by one thread, no other thread will be able to acquire it. This is kind of the very simplest explanation for a race condition I can think of, but expand the playing field to the entire system, where all resources are shared. Now toss in local servers that provide shared services (like a database for instance). Race conditions can be very sticky problems! https://resources.infosecinstitute.com/topic/how-to-exploit-race-conditions/
