Child Process
Child Process is a programming concept where a parent process creates and manages one or more subprocesses (child processes) to execute tasks concurrently or in parallel. It enables applications to run external programs, scripts, or commands, handle inter-process communication (IPC), and improve performance by offloading work. This is commonly implemented in operating systems and programming languages to support multitasking, system calls, and distributed computing.
Developers should learn and use Child Process when building applications that need to execute shell commands, run external tools, handle heavy computations without blocking the main thread, or implement microservices and parallel processing. Specific use cases include automating system tasks (e.g., file operations with 'ls' or 'cp'), spawning worker processes in web servers for load balancing, and integrating with command-line interfaces in DevOps tools. It's essential for creating scalable and efficient software that leverages system resources effectively.
