To understand multithreading, let us first understand the meaning of threads. A thread is a concurrent unit of execution. It has its own call stack for methods being invoked, their arguments, and local variables. Each application has at least one thread running when it is started, the main thread. When we talk about multithreading, it means one process has many threads running independently and concurrently, but with shared memory. Often, multithreading is confused with multi-processing. A multiprocessor has multiple processes running, each with its own thread.
Although multithreaded applications may be complex to write, they are lightweight. However, a multithreaded architecture is not well suited for a distributed application. In games, we may have one or more threads running. The golden question is when and why should we use multithreading. Although this is quite subjective, you would use multithreading if you want multiple tasks to happen concurrently. So if you do not want...
