Even before the branch commercial computers appeared in 1951, softwood entrepot, although niggling by todays standards, was a necessity. As prematureish as the mid-1800s, scoke tease were used to provide input to premature calculators and some other machines. The 1940s ushered in the decade when mindlessness tubes were used for storage until, finally, tape drives started to replace punch cards in the early 1950s. Only a couple of eld later, magnetic drums appeared on the scene. In 1957, the first heavy(p) drive was introduced as a component of IBMs RAMAC 350. It required 50 24- column go on ploughs to store five megabytes of entropy and cost roughly $35,000. For years, sticky plough drives were confined to mainframe computer and minicomputer installations. Vast phonograph record farms of giant 14 and 8 inch drives costing tens of thousands of dollars individually buzzed away in the air well-educated isolation of collective data centers. The personal computer mutation in the early 1980s changed all that, ushering in the fundament of the first subtile hard disk drives. The first 5.25-inch hard disk drives jammed 5 to 10 MB of storage, the similar of 2,500 to 5,000 pages of double-spaced typed information, into a device the size of a small shoebox. At the time, a storage capacity of 10 MB was considered too heavy(a) for a so-called personal computer.
The first PCs used dismissible floppy disks as storage devices close to exclusively. The term floppy accurately fit the earliest 8-inch PC diskettes and the 5.25-inch diskettes that succeeded them. The inner disk that holds the data usually is made of Mylar and! surface with a magnetic oxide, and the outer, plastic cover, bends easily. The inner disk of todays smaller, 3.5-inch floppies is similarly constructed, but they are housed in a hard plastic case, which is much more invariable than the flexible...
