process thread

What is a Thread

A thread is the smallest unit of execution within a process. Multiple threads within the same process share the same memory space and resources, making communication between them fast but also introducing concurrency risks. Threads have their own stack and program counter but share the heap, global variables, and file descriptors with sibling threads.

Use Cases

  • Web servers handling multiple client requests concurrently within a single process
  • UI applications keeping the interface responsive while doing background work
  • Video games running rendering, physics, and audio on separate threads
  • Database connection pools serving multiple queries simultaneously
