Script

A term thread means some kind of minimal process in computer science. Processes and threads are used to simulate parallel execution of programcode. But there is a difference between both: a process describes the execution of a whole program. It contains an image of the programs binary executeable code in memory just as it is used for handling memory allocation by the operating system. However a thread is nothing in this way. It does just describe a parallel execution of code inside a process, so one process can hold multiple threads.

The description above is just one very simple definition of a thread. GTA simplifies multithreading alot so everything the script needs to do is to start a thread and perhaps end it somehow. It does not need to handle variable synchronisation or communication between two threads. This is what the game does through internal routines.
