Process vs Thread

Processes and threads are both units of execution, but they differ fundamentally in isolation and resource sharing. A process has its own memory space and cannot directly access another process's data, while threads within the same process share memory and can communicate instantly. This tradeoff means processes are safer (a crash in one doesn't affect others) but threads are faster to create and coordinate.

Use Cases

  • •Choosing between worker threads and child processes in Node.js for CPU-intensive tasks
  • •Deciding whether microservices should run as separate processes or threads within a monolith
  • •Browser architecture: tabs as processes for isolation vs threads for shared rendering
  • •Selecting multiprocessing vs multithreading in Python based on GIL constraints
