How software works ?
When we request our computer for any data, then our request through the input unit like Keyboard, Mouse is sent to the Central Processing Unit (CPU). A cpu processes the data provided by input unit and with the help of processor, ram and with storage unit, CPU makes the all required Output and this output is sent to the Output unit like Monitor and Sound.
In this way, The software works. The inter-work of the software is all done by the storage unit and processor.
