Data Storage Background

Data storage is the process of recording and storing information on various media for subsequent access. In the distant past, knotted strings were used to store information before writing even existed, as described in an ancient Chinese manual called the Book of Changes (Zhouyi). With the progress of human and technological evolution, words began to be stored on oracle bones, bamboo tubes, and later paper. More recent advancements have led to the explosion of information technology (IT), which has, in turn, fueled the development of various storage hardware devices, such as magnetic tapes and disks. Computers then became a major tool for storing data, allowing us to manage and access data on the storage hardware through storage software.
