Software is the part of the computer that we can't touch

It is the logic that the computer follows.

There is one OS per computer; not more, not less.

The OS defines the internal logic for the fuctioning of the computer.

To program the OS, we must know which are the components of the hardware and how are they connected.

Operating systems evolve along with computers. In the 1990s only one user could interact with a computer and computers only had text, not images.

Computers had one processor, one application, one floppy disc, one keyboard and one screen.

The OS was programmed only to manage those hardware components.

In those days, the OS was stored on a floppy disk, which was loaded after switching on the computer.

The user firts loaded the OS, and then the aplication. The user could then start to use the application.
