Read may refer to any of the following:
1. The term read is used to describe the process of obtaining information from a drive or another storage device and displaying, storing, or processing that information. For example, before this page was shown on your browser, it had to be read from the hard drive and downloaded from our server hard drive.
When saving new information or changes, you write to the drive. If write protection is enabled or you lack the proper permissions you may only have read-only capabilities, which means you can read information but not write or change anything.
