In technical sense, digital storage started out as punch-hole cards or strips that were fed into a computer. Then with the Eniac, the first purely electronic computer storage was available. These first ones were like RAM memory on a average computer, in that when you turned off the power, the data was lost. It was not until the mid 1950s that memory was invented that did not need a constant power sorce. | In technical sense, digital storage started out as punch-hole cards or strips that were fed into a computer.

In the early 60's, The Church of Jesus Christ of Later-day saints began using computers and digital storage to store and alphabetise millions of names. In 1986' the church released the first version of it's PAF program for PC's, making it possible for genealogists to make family trees and store them on magnetic 5 1/4 inch floppy discs. | |||

This type of storage device allows the user to work within the storage device, making changes while working within the file, and easily save changes to a file or database. This type of storage device has many advantages for genealogists, allowing one to work within genealogical databases and frequently add, remove, and change information. | This type of storage device allows the user to work within the storage device, making changes while working within the file, and easily save changes to a file or database.

Optical disks are often used for backing up, storing, or sharing information. Optical disks easily store data such as photographs, movies, audio files, and non-changing data. While optical disks are often thought of as a long-lasting solution to digital storage, the lifetime of optical disks has not been proven. Unlike profesional made CDs, in which the data is recorded onto the disc by stamping pits into the plastic, home-burned disks use chemicals that are burned by the laser. Transferring data onto new disks every 5-10 years is a good practice to preserve information. | Optical disks are often used for backing up, storing, or sharing information.

Genealogists may store small amounts of data on a flash memory device to work with on a regular basis, and back up the information to a larger storage device, such as an external or computer hard drive. Regularly backing up hard drive data to optical disks will help prevent digital data loss. | |||
