What's the Difference Between an Intel Core Duo processor and a Pentium 3 processor? - intel

I need a new computer for school, but specific information about what should be. You will need a Pentium 3, but all I have reviewed Intel Core Duo. What is the difference and will make a difference if I get an Intel Pentium instead?
Thank you!
