Yiddishkeit means Judaism however it is a Yiddish word “Yid” means Jew so Yiddish means Jewish i.e. if someone speaks Yiddish he speaks “Jewish.” So the term Yiddishkiet is a term used by those with Ashkenazic and Yiddish speaking backgrounds, or education.
Yiddishkiet or Judaism is observed by all religious Jews but is basically a term that is only used by Ashkenazim.
As for education, yes for the most part there are separate Yeshivos for all. The main reason being that Sefardim pasken (loosely translated as follow Halachically) the Mechaber (Mechaber means author)(Rav Yosef Karo,who wrote the Shulchon Aruch) and Ashkenazim pasken like the Rema (Rabbi Moshe Isserles who wrote the Hagaah which is an interlinear gloss inside the Shulchon Aruch where he edits the words of the Mechaber of Shulchon Aruch and argues with him). Therefore since there are variations in Halachos and Minhagim the schools are usually separate however you will often find some sefardim in Ashkenazic schools and I assume vice versa although I cant be sure of it.
The Yeshivaworld news caters specifically to those who consider themselves part of the Yeshiva world (more to the right) but not Chassidic.
