computers from 1952 to 2013


1952 computer

  The UNVAC 1 (Universal Automatic computer 1)was the second commercial computer produced in the united states. it was designed principally by j.Presper Eckert and john Mauchly, the inventors of the ENIAC. Design work was begun by their company, Eckert – mauchly computer corporation, and was completed after the company had been acquired by Remington rand (which later became part of Sperry, now Unisys). In the year before successor models of the Univac I appeared the machine was simply was know as “the Univac”.                  

1953 computer

 Ibm shipped its first electronic computer, the 701. during three of production,ibm sold 19 machines to research laboratories, aircraft companies, and the federal government.

1954 computer

 The IBM 650 magnetic drum calculator established itself as the first mass-produced computer, with the company selling 450 in one year. Spinning at 12,500 rpm, the 650´s magnetic data-storage drum allowed much faster access to stored material than drum memory machines

•The process, for which IBM has roped in glue maker 3M, will make PCs and smartphones up to 1,000 times faster than the existing ones and are expected to be available in market as early as 2013. •3M currently makes heat resistant glues, adhesives used in the aerospace industry and sticky tapes, but the hi-tech glues created for IBM could actually be the key step towards making the next evolutionary leap in computing, reports said. •The attempts at piling chips vertically -- known as 3D packaging -- has so far been suffering from overheating. But, the new glues could potentially conduct heat through a stack of densely-packed chips and away from logic circuits that could be burnt out by the heat. •The research aims to create "stacks" of up to 100 layers of silicon, the report said. •Mike Bowman, marketing manager for 3M, said: "This material fits underneath computer chips when they're attached to printed circuit boards -- the unique part of what we're doing is that our glue conducts heat out to the edge of the sandwich.
