What are floppy disks?
Discussion discs are small, removable media storage devices. They record data into a thin circular magnetic film enclosed in a flat square plastic jacket. This type of media is somewhat outdated after it has been replaced by flash memory and overwritable CD storage devices. They were quite flexible and required a floppy disk of the same size. Discs could store up to 360 kilobytes (KB) data or about one third of a single megabyte. Later Flopies with high density held 1.2 megabytes (MB) data. These were widely used until 1987. Newer 3.5 -inch discs (8.89 cm) also had hard shell protection cases, so there is less diskette, although the disk was still used. Some used only one side of the inner magnetic film to record data, which provided them with a capacity of 744 kB. Floppies with a high density of 3.5 inches doubled capacity to 1.44 MB. In fact, there were several configurations, including one -timeor bilateral (SS or DS) and disposable or double density (SD or DD).
easy to see a lower capacity floppy disk was to look at the upper corners of the case or jacket. If the floppy had only one hole on the right, it was a one -sided floppy disk. The hole in the upper right corner included a small plastic card that allowed the user to write down the disk-to.
Since double density floppy disks were cheaper than their high -density cousins, some people in science would buy cheaper discs and then drilled a hole in the upper left corner and converted discs into a double -sided high density disk. All discs contained a polyester film called Bopet - better known as Mylar® - covered on both sides with the necessary magnetic material. Punching the second hole in case of the floppy unit to spin the film in the opposite direction, thus pHe uses both sides.
various technologies have been used since 1991 to extend the life of Flopies by increasing their capacity to 2.88 MB ( extended density or ED), and even 120 MB and 240 MB (LS-120 and LS-240). However, none of these technologies has caught up. The first proved to be too little to increase the capacity for ubiquitous adoption and the second unreliable form of storage.
Today, other storage devices that are more convenient and robust, such as compact disks and flash memory, have largely replaced the floppy disk. The CD can hold up by 600 MB and even the smallest memory monument holds several hundred times the amount of one floppy disk. Some memory sticks now compete with the least disk for the capacity of the disk, which makes them ideal for transferring files, programs or even whole volumes.
The actual character that floppy disks are all obsolete is that most laptops no longer come with a floppy drive and many desktop systems this unitrnums if not required. However, some people continue to use floppy disks and transmission of small files.
