The data downloaded by the user from the Internet gets stored in the hard drive permanently. The files downloaded onto the RAM get erased when the computer is shut down. The data stored on the hard drive remains permanently.

The memory modules are made up of chips and microprocessors. The hard drive is made up of disks and platters. The RAM needs a continuous power supply in order to hold the data on the chip. The data on the hard drive are stored on the magnetic disks. When a user modifies a particular file, the changes are first stored in the RAM.

Once the user saves the changes, the content gets copied to the hard disk. The original copy of the file is untouched in the hard drive until the changes made to the file are saved. Once the file is saved, the original file is replaced by the new version of the file on the hard drive.
