Tanahk is basically the OT. Same books as is included in the OT but arranged differently in the Tanahk.
The Talmuds are commentary of a commentary.
The Mishnah is a codification and collection of "Oral Law" transmitted by word of mouth over generations. Compilled by Rabbi Judah and his court around 160-200 C.E. in Palestine.
The Jerusalem Gemara, is a commentary on the Mishnah by the Amora'im in Palestine, approx. end of the 4th century. Together with the Mishna this forms the JERUSALEM TALMUD.
The Babylonian Gemera, is a compilation of the commentary on the Mishna by scholars in the Babylonian academies, approx. end of the 5th century. This is much larger and more significant than the Jerusalem Gemara. Together with the Mishnah, this forms the BABYLONIA TALMUD.
I guess to make it easy, the Tanahk are the Hebrew writings and the Talmud is commentary. Much like your King James is scripture and your strongs is commentary.
"I guess to make it easy, the Tanahk are the Hebrew writings and the Talmud is commentary"
You should go farther and say that the Torah is the written law and the Talmud is the oral law, lest people think that they can understand Judaism by reading the Old Testament.
