Definition of Data Storage * * Storage Devices are the data storage devices that are used in the computers to store the data. The computer has many types of data storage devices. Some of them can be classified as the removable data Storage Devices and the others as the non removable data Storage Devices. * * Data storage can refer to anything with information recorded on it. Using this broad definition, a hardback volume of an encyclopedia, an audio cassette of a pop song, and even a piece of paper with random words written on it would all be considered examples. The most popular definition of the term limits it to only the storage of information on computers and similar devices.
The memory is of two types; one is the primary memory and the other one is the secondary memory.
The primary memory is the volatile memory and the secondary memory is the non volatile memory. The volatile memory is the kind of the memory that is erasable and the non volatile memory is the one where in the contents cannot be erased. Basically when we talk about the data storage devices it is generally assumed to be the secondary memory.
The secondary memory is used to store the data permanently in the computer. The secondary storage devices are usually as follows: hard disk drives – this is the most common type of storage device that is used in almost all the computer systems. The other ones include the floppy disk drives, the CD ROM, and the DVD ROM. The flash memory, the USB data card etc.
History of Data Storage * The earliest known form of data storage was punch cards which were created in 1725 by Basile Bouchon. They had a perforated paper loop to store patterns which could be used on cloth. In 1846 Alexander Bain improved on this idea with the invention of punched tape which could hold significantly more data than their predecessor. * * With the invention
