## Definition

a computer program that is started by another program. You use this term when one main task creates smaller tasks to help it finish its work.

For teachers: a subprocess generated by a parent process within a multitasking operating system. It inherits certain attributes from the parent and typically operates under its control or monitoring.

## Examples

- The main program starts a child process to handle the data.
- When the web browser crashes, it is often because a specific child process failed while loading a heavy website.
- The operating system must efficiently manage the termination of each child process to prevent the accumulation of zombie processes that consume system resources.

## Usage notes

- primarily used in computing and software development contexts; usually functions as a countable noun.
- Teaching tip: use the parent-child metaphor to explain the hierarchy of execution and resource inheritance in operating systems.
