Orthodox Jews believe that the Torah must be fully observed. They keep the laws of Judaism as codified in the Shulchan Arukh (Code of Jewish Law), which lists the laws of the Torah and Talmud. Torah-study is seen as very important; and the modern world is seen as subservient to the Torah, not the other way around.
Other Jewish groups (Conservative, Reform) adapt or change the Torah-laws in contemporary life, to a greater or lesser degree.
In between the Orthodox and Reform Jewish communities is the Conservative movement, although, the Conservative movement is closer to Orthodox than Reform.
No Orthodox groups recognise Reform conversions.
There are three sects of Judaism: Orthodox, Conservative and Reform.

Conservative, Reform and Orthodox
The major modern Jewish sects are: Orthodox Judaism, the most traditional, which attempts to follow the Torah explicitly; Reform Judaism, the most liberal, containing 42 percent of American Jews; Conservative Judaism, between Orthodox and Reform, based on the teachings of Zacharias Frankel; and Hasidic Judaism, which promotes internal mysticism.
Judaism is divided into 3 main branches, which are Reform, Conservative, and Orthodox, although there is a form of orthodox Judaism known as Hassidic Judaism which might be described as ultra-orthodox. Reform Judaism is a modernized version in which Jews do not have to wear special religious clothing (such as the skull-cap or yarmulka) except on special occasions, and in which the demands of the religion are relatively moderate. Conservative Judaism requires Jewish men to wear their religious head-gear at all times, and requires more ritual observance than Reform Judaism. Orthodox (or ultra-orthodox) Judaism makes no compromises with the modern world, insisting upon every traditional detail of Judaism as it existed earlier in history. Being an orthodox Jew could be described as a full-time occupation. It is a very demanding religion.
