What is a bubble memory?
Bubble Memory is a type of computer memory invented over the 70th years Andrew B Generk. It is volatile, which means that the data is stored even when the computer is turned off. Domains or "bubbles" created on a magnetic movie can store pieces of data. In general, one data bit is assigned to one bubble. The magnetic shield closes all elements, but on one side exposes several magnetic connectors. If the user connects the unit with the energy source, the magnets inside can create small bubbles in the movie and store pieces of memory. The bubbles are arranged in a pattern that monitors the binary system. One bubble represents a binary digit and the absence of a bubble means zero.
Several companies have created and launched bubble memory technology in an effort to replace hard drives. Intel, Fujitsu, Rockwell and Texasvs have created their own models of these memory units. The units were initially advantageous because they are removable and highly resistant to different elements such as temperaturest and radiation. It was soon found to use so much energy to activate bubbles and required a more complex operating system compared to hard drive. Production costs were also more expensive than the rival hard drive.
Bubble memory units were also too bulky; They were slightly smaller than the size of the regular boxing of matches, but stronger and heavier. They also had slower operating speeds and had no random access. At the beginning of the 80s, hard drive technology became more advanced and the selling price became cheaper, so the production of bubble memory was interrupted.
While the bubble system has not become popular in modern computers and gadgets, the area of "harsh" factory machines, mainly because of its physical resistance and a leak quality, grow. It was also temporarily used in video games in which the memory cartridges can be separated and replaced for the production of games. Its robus also made a preferenceFor military use even after its completed production. However, the development of other non -volatile memory units, such as compact discs and keys from the universal serial bus (USB), became reopened for bubble memory. Smaller sizes of more modern devices, not to mention higher memory capacity, also joined the obsolescence of the bubble system.
