Memory History Computers Top New

Not 64GB enough? How memory evolved in computers.

In the 19-20 century, data recording technologies were actively replaced and their performance grew exponentially. I would like to note the prefactors that used the holes in the paper as a memory cell and then read it out. The Williams-Kilburn tube, who first came to the concept of a binary code using a ray tube electrode, he would later collaborate with IBM and other world renowned companies with his patent. Ferito memory, which quickly replaced William's work with its incomparable memory volume of 4-16Kb :D.

But the aforementioned technology races have sprung up their giants. So the well-known CDs and DVDs broke into the 80-90s with breakthrough technologies and huge support due to the active development of personal computers and the demand for data exchange.

But the giants are falling as well, introducing the hard drive, which was first released by IBM in 1956 as part of the IBM 305 RAMAC mainframe. The disc weighed 0.9 kg, had a capacity of 3.75 MB and a recording density of 2000 bits per square meter. inch. To date, hard drive density has increased more than 60 million times, and capacity costs have dropped from $ 9,200 to $ 0.000003 per megabyte. Today, anyone can purchase a hard drive for storing information directly from themselves.

Also, the issue became popular with portability and humanity received memory cards, which were much smaller than hard drives. Now memory cards and hard drives are at the Olympus in the technology race.
