Operating System
The following process then takes place
When we save the document, the operating system looks for free space on the hard disk and transfers the data from the memory to that space.
To print, click on imprimir, and the word processor will send the command to the operating system, which sends the appropriate signals to the printer .
The program is now the active application. It receives data from the keyboard and sends instructions to the microprocessors through the operating system
When we close the word processor, the operating system deletes the application from the memory, though not from the hard disk.
The operating system finds the application on the hard disk, sends a copy of it to the RAM, and loads into the screen
