Information storage technology

Right!

Information storage technology refers to technology that saves information across time. It mainly includes data compression technology, micro-storage technology,

Magnetic storage technology, microfabrication technology and optical disk technology have become the three pillars of modern information storage technology. Modern information storage technology has not only increased the density of information storage, but also combined information storage with rapid retrieval, which has become the basis for the development of information work. ^[1]

1. Indexes for evaluating storage technology ^[2]

The human brain's memory function can store the information collected by the above-mentioned various organs through appropriate coding and storage. Therefore, the brain is also an important information storage component of the human. The storage of information is the basis for the transmission of information in the time domain, as well as the basis for the further integration, processing, accumulation and regeneration of information. It is of great significance in human and social development; but the function of brain storage is still affected by the brain storage Limitations on natural capabilities such as capacity, memory capacity, and access speed. Especially because the life span of a person is limited, the information stored in the human brain disappears after a person dies. Although the human reproductive genetic function can pass information on some natural attributes of the human being to the next generation, it cannot pass the information stored in the human brain, so people have invented and created papermaking, printing, photography, and videography. Technology, sound recording, video recording technology, and various information storage technologies such as magnetic disks, magnetic tapes, and optical disks. These artificial information storage technologies and devices not only have the potential to expand the storage capacity of the human brain in terms of storage capacity and access speed, but also have two more important meanings: First, they transfer information from people's subjective understanding of the world to In the storage medium of the objective world, they can be passed down from generation to generation due to the limitation of human death. Second, they can be separated from the limitations of the individual brain and become knowledge shared by human society, and become important for information exchange between people in society. medium. ^[3]
