    IBM sent the IBM 1401 mainframe based on transistors

    IBM sent the IBM 1401 mainframe based on transistors, which used punched cards. It proved to be a general-purpose computer and 12,000 units were sold, making it the most successful machine until that time. It had a magnetic core memory of 4000 characters (later extended to 16,000 characters). Many aspects of his designs were based on the desire to replace the use of perforated cards, which were widely used from the 1920s to the early 1970s.

    IBM announced the 360 ​​series

    which was the first family of computers that could run the same software in different combinations of speed, capacity and price. It also opened the commercial use of microprograms, and a set of extended instructions to process many types of data, not just arithmetic. In addition, the IBM product line was unified, which previously had two separate lines, a "commercial" product line and a "scientific" line. The software provided with the System / 350 also included major advances,

    IBM sold its first magnetic disk system, the RAMAC,

    IBM sold its first magnetic disk system, the RAMAC (Random Access Method of Accounting and Control) for a value of 1,230,000 dollars. He used 50 61 cm metal discs, with 100 tracks per side. It could store 5 megabytes of data, at a cost of 10,000 USD per megabyte.
