Detailed explanation-1: -It depends entirely on what happened to the server. If the drive where the data is held is wiped out, or destroyed, then yes, it’s gone. If you never backed up your data, then it’s gone. Just because a server went offline, doesn’t necessarily mean that any of that stuff happened.
Detailed explanation-2: -Data is represented on modern storage media using the binary numeral system. All data stored on storage media – whether that’s hard disk drives (HDDs), solid state drives (SSDs), external hard drives, USB flash drives, SD cards etc – can be converted to a string of bits, otherwise known as binary digits.
Detailed explanation-3: -Random Access Memory is volatile. That means data is retained in RAM as long as the computer is on, but it is lost when the computer is turned off. When the computer is rebooted, the OS and other files are reloaded into RAM, usually from an HDD or SSD.
Detailed explanation-4: -A hard disk drive or solid state drive holds all of the data; files, photos, programs, music, and movies, that the user wants to keep.
