=== History === | |||
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 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. 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.

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. | ||

Solid state devices are a great way to quickly check, update, transfer, and share data. They provide a temporary storage solution for portable information. Solid State devices provide a quick, easy, and accessible way to gather, add, and temporarily store genealogical information until it may be organized and stored in more permanent formats. | Solid state devices are a great way to quickly check, update, transfer, and share data.

Magnetic storage is often used as a long-term storage solution, often with regular backups of information. The most common form of magnetic storage is the hard drive. Hard drives help genealogists quickly add, change, locate, and share information. Hard drives are used in computers, servers, and external hard drives and are magnetically coated disks with magnetic particles. Unlike solid state devices, damaged hard drive data may often be recovered. | Magnetic storage is often used as a long-term storage solution, often with regular backups of information.
