By default, foreground processes in Kali Linux are executed in the terminal window, blocking other commands until their completion.

This means that when you execute a command in the foreground, the terminal waits for it to finish before allowing you to execute additional commands or interact further with the terminal interface. This behavior contrasts with background processes, which can run concurrently with other commands and do not block the terminal interface. Background processes allow you to continue working in the terminal while they execute.
