THE DIFFERENCE BETWEEN A PERMANENT HARD DISK DRIVE AND A REMOVABLE HARD DISK DRIVE A permanent drive is in housed in the system while the removable one is externally fixed. Basically they perform the same functions.
RAM is volatile, which means when you shut your computer off any data that is in RAM will be erased. For instance start typing a letter in word and shut your computer down after typing 2 sentences and do not save it. When you bring it back up the letter will no longer be there because it was not saved to the hard drive, it was in RAM. A flash drive is non-volatile, which means the data stays in the flash drive even if there is not power to it. It's just like a hard drive.
