The biggest difference in ROM and RAM is that one is permanent whereas the other is temporary. ROM (Read Only Memory) is permanent and does not change unless you perform a firmware upgrade. The ROM is what allows your computer to start up and perform its initial boot functions. The RAM (Random Access Memory) is only available while the computer is on and active. Once the computer is shut off the RAM resets. RAM reminds me of the movie 50 First Dates, where Drew Barrymore loses her memory every time she goes to sleep. RAM functions the same way. RAM is also more easily modified and customizable in that if you have the right set up you can change to variations of DDR (Double Data Rate) which basically increases data communicated per clock cycle.
