Computer storage evolution

The evolution of Computer Stórage Computer technology has come a long way since the first attempt to store data, especially considering how much storage is possible today. We might think of floppy disks as ancient history now, but the history of computer storage goes back much further than that. Explore the evolution of computer storage and what could be in store for us in the future in this graphic from American Internet Services (AIS). 1928 - Magnetic Tape Fritz Pfleumer, a German engineer, patented magnetic tape 1946 Williams Tube in 1928. He based this invention off of the magnetic wire originally designed by Vlademar Poulsen. Professor Fredrick C. Williams and his colleagues developed the first random access computer memory at the University of Manchester using a series of electrostatic cathode-ray 1928 Solectron Tube tubes. The Radio Corporation of America (RCA) developed an early form of computer memory using a Solectron tube for high-speed Delay Line Memory -1949 data registry. 1956 - This early form of computing would impart an information pattern into a delay path to generate a memory capacity of a few thousand bits with recirculation times measured in Hard Disk A hard disk implements rotating platters, which store and retrieve bits of digital information from a flat magnetic surface. microseconds. -1963 Music Tape 1966 - Dram ( PDF ) DRAM The first audiocassettes were intended for dictation machines but In 1966, Robert H. Dennard invented DRAM cells, which store bits of data as an electric charge soon became a popular method for distributing music to the masses. within a circuit for increased 1980 Compact Disk memory density capabilities. James T. Russel was the first to conceptualize the idea of using light to record and 1989 - replay music. Years later, Russel successfully completed the design and presented it to Sony. DDS Digital Data Storage In 1989, Sony and Hewlett-Packard introduced the Digital Data Storage (DDS) format to store and back up computer data on magnetic tape. 1992 Mini Disk Sony was the first to introduce the MiniDisk digital storage 1994- technology that was intended to Compact Flash replace the audiocassette tape memory device. CompactFlash (CF) uses flash memory in an enclosed disc to save digital data and is most commonly used to store information in digital cameras. -1995 DVD DVDS became the next generation of digital disc storage and are credited with 2003 being a faster and bigger alternative to CDs for storing multimedia information. Blu Ray Blu-ray allows us to store high-definition video and high-density data and is named for the blue-laser technology used to store and read large amounts of data. Today Cloud Computing Cloud services enable a shared infrastructure that offer a wide range of benefits, including easy disaster recovery and rapid scaling of massive quantities of virtual data. Regardless of company size or industry, ensuring that mission-critical IT resources can withstand disruption is absolutely necessary in today's networked economy.
