Multiple-document interface. A multiple-document interface (MDI) is a graphical user interface in which multiple windows reside under a single parent window. Such systems often allow child windows to embed other windows inside them as well, creating complex nested hierarchies. This contrasts with single-document interfaces (SDI) where all ...

When a child process terminates before the parent has called wait, the kernel retains some information about the process, such as its exit status, to enable its parent to call wait later. [4] Because the child is still consuming system resources but not executing it is known as a zombie process .
A modal window creates a mode that disables user interaction with the main window but keeps it visible, with the modal window as a child window in front of it. Users must interact with the modal window before they can return to the parent window. This avoids interrupting the workflow on the main window. Modal windows are sometimes called heavy ...

When a top-level window is created, a re-parenting window ...
A server process is also said to be orphaned when the client that initiated the request unexpectedly crashes after making the request while leaving the server process running. These orphaned processes waste server resources and can potentially leave a server starved for resources. However, there are several solutions to the orphan process problem:
fork() is the name of the system call that the parent process uses to "divide" itself ("fork") into two identical processes. After calling fork(), the created child process is an exact copy of the parent except for the return value of the fork () call. This includes open files, register state, and all memory allocations, which includes the ...
Spawn in computing refers to a function that loads and executes a new child process. The current process may wait for the child to terminate or may continue to execute concurrent computing. Creating a new subprocess requires enough memory in which both the child process and the current program can execute. There is a family of spawn functions ...
