What is the removable media?
Rewards media is a method of storing computer data through usually magnetic or optical means since 2011. This data has been contained on portable storage devices that are not physically connected to a computer permanently, such as a factory installed. There are many different types of removable media and the hardware industry that creates them is constantly evolving. The tape units were the first forms of removable electronic media made in the 1950s, but the formats sold for personal computers known as floppy disks did not appear until the end of the 70s until the early 80s. Since 2011, many new types of storage devices have been created, each with its own unique advantages and disadvantages.
The least portable method of magnetic removable media repository created in 1951 was a tape unit that was often used to back up the company server, and at first it could only have 224 kilobytes of data. Unit of tape withFurthermore, it has developed used in environments where a large number of corporate, government or personal data must be stored by a semi -inflate basis. Since 2011, there are tape units that can hold up to 5,000 gigabytes of data or 5 terabytes, which is about 22,000,000 more data than the first tape units could hold in 1951.
magnetic tapes known as floppy disks appeared for basic computer systems in 1983 and were either 5.25 inches (13.34 centimeters) size or 3.5 inches (8.89 centimeters), holding a maximum of about 1.2 megabytes. In 1994, these technologies and formats were replaced by the introduction of a zip disk, which resembled a stronger 3.5 -inch floppy disk (8.89 centimeter) and required a separate hardware system to connect to the computer system. Zip disk initially could hold 100 megabytes data and was soon replaced by models with higher densitythat could accommodate 250 megabytes and then 750 megabytes.
magnetic removable media was outdated at the beginning of the 90s. The optical data storage became practical. In 1997, the memory memory platform with a compact disk (CD-ROM) was widely available as a method of optical data storage. Optical disks readers have become the standard in personal computers, replaced the older floppy readers and made unpleasant and expensive peripheral zipper readers. While the CD-ROMs held only about 700 megabytes of data, they were considered more versatile and reliable than magnetic forms of storage and could be produced in bulk at a unit per unit than zippered discs and zipper disks.
Since 2011, CD-ROM discs have largely been replaced by digital video technology (DVD), where the only DVD is able to stick from 4.7 to 17.08 data gigabytes. As a result, the storage capacity of DVD is equal to at least 7 CD-ROM discs. Optical discs such as DVDs are captured afterThe market part is largely because they can maintain the entire content of video presentation, such as commercial film, while it was not possible for earlier forms of removable media. Blu-ray was a new DVD format created in 2000, which used a more compact blue laser to write data on a disk. Invented by Sony Corporation in Japan, Blu-ray format can old from 23 gigabytes to 54 gigabytes to disk since 2011.
Since the field of removable media continued in the procedure, many types of portable magnetic storage options have become popular on the market, including universal serial buses (USB) flash drives, secure digital (SD) cards and compact, external hard drives connected by USB. Flash units can hold up to 16 gigabytes each since 2011 and are very popular because they are small units of inch size for which almost all personal computers have USB ports and include software designed to easily read the content of the unit as soon as they are behindbonded.
