Jews practice Monotheism (only one God). Most Christian denominations practice Trinitarianism (three gods in one) and some Christian denominations believe in Tritheism (three distinct and separate gods).
Christianity and Judaism are two of the three great monotheistic religions, the third being Islam.
Answer 2
No Christian denomination practices Trinitarianism in the sense stated in the answer above for no Christian believes in more than one God or god. All Christians believe in only one God or they would not be Christian.
All Christian churches believe in the doctrine of the trinity as stated in the Apostles, Nicene, and particularly the Athanasian creeds.
Note that in the text of the Athanasian creed the word Catholic means Christian, not Roman Catholic as it means today. In other words, the Athanasian creed was a statement of Christian doctrine, to combat a number of errors which arose at that time, particularly Arianism, which taught that Jesus was not God.
The Hebrew religion came to it's finish when Jesus God's anointed son came on the scene. The old covenant eventually became obsolete. Read Hebrews 8:6,9,10. Hebrews 12:24. The Hebrew religion was a tutor which led to the Christ.
Christian answer
There really is not difference. They are both Jehovah. However, Christians believe that Jesus Christ is the Messiah. Jews believe that the Messiah has yet to come. So both groups worship the same God. There are difference in beliefs after that, though.
Jewish answer
Both religions believe in the same God, (though the J word mentioned in the previous answer is not accepted by Jews the name of God, rather it's the result of a Medieval Christian misunderstanding of a Jewish writing convention. Google "Tetragrammaton").
Here are some differences in how God is understood in the two religions (these are general differences and do not apply to ALL Jews or ALL Christians):
While Christians believe in a trinity, Jews believe in One God with no son, partner, or virgin birth.

Dictionaries define "Judaism" as The monotheistic religion of the Jews, since the founding principle of Judaism was and is the belief in One God. This was the teaching which was spread by Abraham, and has continued since then.
In Judaism:
God is One. The concept of a dualism (as in Zoroastrianism), an independent Satan, multiple gods (polytheism; paganism) or a trinity of three in one, are all unimaginable in Judaism. Also, any belief that an intermediary between humanity and God should be used, whether as necessary or even optional, is considered heretical.God is non-physical, indivisible and incomparable.
While Christians believe in a trinity, Jews believe in One God with no son, partner, or virgin birth.
The difference between the Christian God and the Japanese god is that the Christian God is the only God. There is no Japanese god. The Christian God is real and the Japanese God is fake.
In the Jewish one the god kalashnikov-imhotep dropkicked a giant ewok and it became the sun. He then proclaimed that rainbows are the harbingers of the doom and pestilence....of course not, check wikipedia.

I wasn't born a Christian and I waited as long as I did to become a Christian. There is a difference between being a Christian and not being a Christian; and I thank God, I finally accepted Jesus into my life. As the Roman Soldier said at the Cross; this Man (Jesus) is the Son of God!.
You do realize, that the Jewish God is the same God as the Christians. So the Jewish god is known for the creation of the universe and mankind. He is also known as the father of Jesus Christ. The difference between the Jewish religion and the Christian religion is that the Jews did not belive Christ was the mesiah; they belived that their savior has yet to come. And yes it is true that the Jews are the ones responsible for the death of Christ. Many people dislike the Jews for this history. A lack of forgivness. You see Jesus forgave them, despite the fact he was the one hanging on the cross. "Father forgive them for they know what they do" is all he said.The Jewish belief is actually very peaceful.
That's like the difference between knowledge and math. Math is one branch of study; and Kaballah is one area within Judaism. It includes mystical levels, such as deeper meanings within Torah verses, and details of God's name.
One main difference between them is that the Jehovah's Witnesses speak and tell people that the name of god is Jehovah (or Yahweh). The Jewish people practice not pronouncing the name of the Divine God because of superstition or that the divine name is too holy to be spoken by imperfect lips. Another difference is that the Jewish people believe that Jesus is NOT the Messiah. The Jehovah's witnesses believes otherwise.
