The Bernoulli Box is released. 1969 - Intel begins as chip designers and produces a 1 KB RAM chip, the largest memory chip to date. DVD cover for Twister, the first commercial DVD release. Referred to as random-access memory or RAM, it allowed data to be accessed randomly, not just in the sequence it was recorded. Sperry Rand developed this faster variation on core memory. Allowing for many times the amount of storage afforded by a regular floppy disk, the cartridges came in capacities ranging from 5MB to 230MB. In 1953, MIT’s Whirlwind becomes the first computer to use magnetic core memory. 1985: Control Data, Compaq Computer, and Western Digital collaborate to develop the 40-pin IDE interface. Magnetic tape allows for inexpensive mass storage of information and is a key part of the computer revolution. 1932 - Gustav Tauschek invents drum memory in Austria. Storage Tek announces upgrades to its 4400 ACS tape library. Each core stored a bit, magnetized one way for a “zero,” and the other way for a “one.” The wires could both detect and change the state of a bit. IBM's 9345 hard disk drive is introduced. 1936 - Konrad Zuse applies for a patent for his mechanical memory to be used on his computer. Early mechanical tools to help humans with digital calculations, like the abacus, were referred to as calculating machines or calculators (and other proprietary names). Hitachi purchased IBM's hard disk division in 2002, which included the Microdrive. 1947 - Frederick Viehe of Los Angeles applies for a patent for an invention that uses magnetic core memory. The 1311 offered some of the advantages of both tapes and disks. It offered better audio and video quality than its competitors, but LaserDisc players were prohibitively expensive for many consumers. The mylar cards were suspended from rods that selected and dropped one at a time for processing. Two groups, made up mainly of Japanese technology companies, had been developing competing, optical disc storage formats. EDSAC, a stored program computer, used mercury delay line memory. It was an attempt to lower maintenance costs while bolstering disk drive reliability. Winchester technology drive arrays were IBM’s last storage system with large removable disk packs. The first significant company to adopt the 3 ½-inch floppy for general use was Hewlett-Packard in 1982, an event which was critical in establishing momentum for the format and which helped it prevail over the other contenders for the microfloppy standard, including 3-inch, 3 ¼-inch, and 3.9-inch formats. Seagate Technology creates the first hard disk drive for microcomputers, the ST506. Feb 22, 2017 - Memory & Storage | Timeline of Computer History | Computer History Museum It evolved into Digital Linear Tape (DLT), and was widely used in medium and large-sized Local Area Networks. It introduced a number of web services, including Amazon Elastic Cloud 2 (EC2) and Amazon Simple Storage Service (S3). Storage Tek was one of the first major players in the automated tape library sector, and competed with IBM for market share. UNIVAC introduces the "UNISERVO" tape drive for the UNIVAC I computer. In a departure from using magnetic core memory technology, IBM introduces the System 370 Model 145 mainframe computer, the company's first all-semiconductor memory computer. The tube, tested in 1947, was the first high-speed, entirely electronic memory. A prototype solid state disk (SSD) module is made for evaluation by IBM. Programs, data, bandwidth, memory: IT: Mechanical(engineering) Energy: Hardware, motherboard, telephone, FAX: Technology: Table 1.1: The levels of computing . In Science and Technology. They could be rewritten up to one million times. They were designed for small and medium sized businesses in addition to general consumers. Each pack weighed about ten pounds, held six disks, and had a capacity of 2 million characters. The IBM 726 was an early and important practical high-speed magnetic tape system for electronic computers. Vendors announce cloud-based network-attached storage solutions for online backup. Like all delay lines, bits were fed into one end, detected at the other, and continuously recirculated. Only eight were sold. The 1 MB memory chip is developed. Although this type of delay line was considered to be somewhat slow, its low cost made it attractive to computer designers. This rope memory was made by hand, and was equivalent to 72 KB of storage. This tape robot was used in a variety of installations, and one was used at the Stanford Linear Accelerator Center (now the SLAC National Accelerator Laboratory) to store data from experiments, providing medium-speed access to immense amounts of data. Due to the customer-investor relationship with Compaq, Conner Peripherals became one of the fastest growing US companies at that time. They were designed for data protection, and along with backup capability it also provided a data recovery solution. Resources . As such, the Deskstar had a greater storage capacity by a factor of 300,000 and was thousands of times smaller. Between various devices peripherals became one of the Intel 1103 memory chips added.
