concurrent threads meaning
What does it mean if an application is concurrent?
Concurrency means that an application is making progress on more than one task at the same time (concurrently). Well, if the computer only has one CPU the application may not make progress on more than one task at exactly the same time, but more than one task is being processed at a time inside the application.
Can two threads run concurrently on the same processor core?
Two threads can run concurrently on the same processor core by interleaving executable instructions. For example, thread 1 runs for 10ms, thread 2 runs for 10ms etc. Parallel processing is a type of concurrent processing where more than one set of instructions is executing simultaneously.
What is a process with two threads of execution?
A process with two threads of execution, running on one processor In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system. In many cases, a thread is a component of a process.
Does Java support concurrent threads?
Like most modern programming languages, Java supports concurrent threads; Java is a multithreaded programming language. We have already seen this in the context of graphical user interfaces. Concurrency is important for two major reasons. First, it helps us build good user interfaces.
