I know that the sources (typograficas) serif are a type of sources. Now my question is in CSS when you put a paragraph to the source type font-family: serif; which source it takes. I would like to know if this changes in different devices (or SOs) or if in fact the serif source is also a source, because I put the source only serif to my blog and I would like to know if it changes or is the same source in all the devices.
The
font-familyproperty is a group of sources, which may contain Various names of sources as an "alternative" system. If he browser does not support the first source, try the following source.
When the typeface is not explicitly set, or not installed, the browsers display the text with a default font
Within the page link you will find a form to see information about different fonts and how they would appear in Browsers / different S.O
As you have been told in the comments, the default sources vary depending on the browser (and sometimes the OS), for example the "serif" of Firefox may be different from the one used by chrome.
It is recommended that you specify your typeface to avoid these details, or you could also use a "font stack", which is used to define several sources to choose from, so you could put the first one as the preferred option and in case of not find it, the second one will be used etc ..

EDIT:
In chrome you can check it in chrome: // settings / fonts In Firefox in the settings - > language and appearance - > Where is the default source there is an "advanced" button (advanced options) and there you can review
