computers from 1952 to 2013
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”.
•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.
