History of Computer Storage
-
Magnetic Drum
An Austrain innovator, G. Taushek invented this in 1932. He based off his invention off of a discovery credited to Fritz Pfleumer. -
Williams Tube
A Professor, Fredrick C. Willaims and his colleagues developed the first random access computer memory at the University of Manchester. He used a series of electrostatic cathoderay tubes for digital storage. -
Selectron Tube
The Radio Corportation of America developed this. It was an early form of computer memory. -
Delay Line Memory
This consists of imparting an information pattern into a delay path. A delay line memory functions similar imputting a repeating telephone number from the directory until an individual dials the number. -
Hard Drive
This implements rotating platters, which stoes and retrieves bits of digital information from a flat magnetic surface. -
Music Tape
Phillips originally intended to use the audio cassette for dictation machines, however it became a popular method for distributing prerecorded music. -
DRAM
Robert H. Dennard invented DRAM cells. Which stands for Dynamic Random Access Memory technology, or a memory cells that contained one transistor. -
Twistor Memory
Bell labs developed this by wrapping magnetic tape around a wire that conducts electric current. These were totally replaced by RAM chips, later on. -
Bubble Memory
Andrew Bobeck invented this in 1970, it is a thin magnetic film used to store one bit of data in small magnetized areas that look like bubbles. -
8" Floppy Disk
IBM came up with this. It is a portable storage device made of magnetic film encased in plastic. Making it easier and faster to store data. -
5.25" Floppy
This was developed in 1976 by Allan Shugart, he created it because the 8" Floppy Disk was too large for standard desktop computers. The storage capacity of 110 kilobytes. It was cheaper -
CD
James T. Russel during the 1960's thought of using light to record and play music. But he then invented the optical digital televison recording and playback televison in 1970, but noone bought it. Phillips paid James millions for him to develop the CD, he presented it to Sony. -
CD ROM
Also known as Compact Disk Read-Only Memory. It ecodes tiny pits of digital data into the lower surface of the plastic disc, allowing larger amount of data to be stored. -
DAT
Sony introduced the Digital Audio Tape, a signal recording and playback machine. It resembled the audio cassette tape. -
DDS
Sony introduced the Digital Data Storage format to store and back up computer data on a magnetic tape. -
1994 Compact Flash
AKA Flash Drives used flash memory in an encolsed disc to save digital data. -
ZIP
it was commonly used in 1994 to store digital files. -
SmartMedia
A flash memory card. -
CD
It became the next generation of digitial disc storage. A bigger and faster alternative to the compact disc, serves to store multimedia data. -
Multimedia Card
It uses flash memory card standard to house digital data. -
SD Card
The Secure Digital flash memory format incorportates DRM encryption features that allow for faster file transfers. -
Cloud Backup Solutions
Zetta's cloud enables businesses to protect data using backup, recover from a disater and archive unused files using only a lightweight software client and Zetta's bi-coastal datacenters.
