Title
*ponders* thread and process architecture
Description
Process Architecture Philosophy (Isolation & Protection)
Core Idea: Each process is a distinct, independent world with its own virtual memory, file handles, and resources.
Focus: Security, stability, and fault containment (one process crashing doesn't affect others).
When to Use:
Running separate applications (e.g., browser tabs, different software).
Tasks requiring high security or running untrusted code.
When tasks are heavy and don't need frequent shared data.
Trade-off: Slower communication (IPC needed) and heavier context switching (saving/restoring entire memory maps).
Thread Architecture Philosophy (Sharing & Concurrency)
Core Idea: Threads are lightweight sub-tasks within a single process, sharing the same memory, code, and resources.
Focus: Responsiveness, efficiency, and easy data sharing for concurrent operations.
When to Use:
Performing multiple tasks within one application (e.g., UI updates while downloading).
CPU-bound tasks that benefit from parallelism on multi-core systems.
Trade-off: Lack of built-in isolation; requires careful synchronization (locks, mutexes) to prevent race conditions and data corruption.
