The Torah is the compilation of the first five books of the Hebrew Bible, namely the books of Genesis, Exodus, Leviticus, Numbers and Deuteronomy. In that sense, Torah means the same as Pentateuch or the Five Books of Moses. It is also known in the Jewish tradition as the Written Torah. If meant for liturgic purposes, it takes the form of a Torah scroll (Sefer Torah). If in bound book form, it is called Chumash, and is usually printed with the rabbinic commentaries (perushim). The Jews write down the Torah, the earliest part of the text subsequently known to Christians as the Old Testament.
