Ancient information storage tools, what is the difference between ancient and modern information sto

Knotted rope notes. Book, Jane, silk, paper.

1. Information carrier.

At the earliest, counting fingers, knotting rope notes, replacing stones, and painting on the rock walls of caves; After that, bamboo slips, wooden slips, metal container surfaces, silk, silk, Cai Lun paper, leaves of broad-leaved plants (tropics), animal skins, paper, etc.

Nowadays, paper is a widely used information carrier, and magnetic storage media, electronic information storage media, optical storage media, etc. have also penetrated into your life.

In the future, people will explore information carriers with higher storage density and more stable storage status. Such as biological storage – storing information with DNA.

2. Recording method.

In the earliest days, "things are written down by things" or "things are debited", that is, things to be recorded are replaced by things that are easier to carry, but at this time all "things" are things in the real sense. Later, humans learned to replace things with more concise symbols. From "hieroglyphs" to "modern scripts", which were constantly evolving and updated.

Moreover, with the development of computers, people take advantage of the concise characteristics of binary digits to correspond to binary digits and information through formula conversion, so that they can use the magnetic storage medium (disk) optical storage medium (optical disc) or electronic information storage medium (memory, U disk) mentioned above to record.

3. Information processing tools.

Manuscript calculus, abacus, calculators, etc.

When there is no writing and no pen and paper, people use a knot of string to help memory, but the disadvantage of this method is that it is easy to confuse memory. After the advent of writing, people first recorded information on stones, walls, and later on animal bones and animal carapaces. When there was pen and paper, people began to write down the information on paper.

Nowadays, in addition to paper, there are also people who store information in computers.

In ancient times, information was recorded in the form of writing, printing, etc., on stone, bamboo, silk and paper, forming a book.

In modern times, it is recorded on paper in the form of writing, printing, etc. After the invention of photographic video technology, it was possible to record screen information.

Modern, mainly based on hard disk or cloud service storage for print and data.

Storage medium. Advantages of paper: large stock, small size, cheap, good permanent preservation, and not easy to alter. It's as easy to save numbers, text, and images as possible.

Disadvantages: Slow transmission of information, inconvenient retrieval.

Advantages of film: high storage density. Easy to query.

Disadvantages: Reading must go through the interface device, inconvenient, **expensive.

Advantages of the computer: extremely fast access speed, large amount of data stored.

Information storage should determine what information exists on which medium lines are appropriate. In general, voucher documents should be stored on paper media; storage of business documents on paper or tape; and the master file, such as the corporate structure within the enterprise; Personnel dossier; Inventory accounts of equipment or materials should be kept on disk for online retrieval and query.

Migratory birds, especially pigeons, geese, etc., are used as transmission tools;

Ways to make fillings, such as hidden in fish maw, cakes, buns, etc.;

with special sounds, such as bells, drums, firecrackers, etc.;

With lights, firelight, such as Kong Ming lanterns. beacons, etc.;

There are also other signs, ornaments, etc., such as signs to lure the enemy.

It is recorded in the form of writing, printing, etc. on stone, bamboo slips, silk, and paper to form a book.

With the invention of the telegraph and the discovery of electromagnetic waves, a fundamental change has been made in the field of human communication, and the electrical impulses on metal wires have been realized to transmit information and wireless communication through electromagnetic waves.

With the rapid development of electronic technology, the military system, scientific research, and computing tools that urgently need to be solved have also been greatly improved, and the first electronic computer developed by the University of Pennsylvania in the United States was born in 1946.

In order to solve the problem of resource sharing, a single computer soon developed into a computer network, which realized data communication and data sharing between computers.

Written and printed on paper. After the invention of photographic video technology, it was possible to record screen information.

Cable communication transmission, such as fax, telegram, television, etc.;

Wireless communication transmission, such as walkie-talkies, BP machines (to eliminate), mobile**, radio;

Digital communication transmission, the most familiar, networked computers, digital television;

Paper communication transmission, such as letters, newspapers, etc.

It is mainly stored on hard disks or cloud services for printing and data.

Drawings, murals.

Recorded with bamboo slips and silk silk as the medium.

Clay pots, inscriptions cast in porcelain, or drawings.

Mass recording, copying, movable type, and stereotype on paper.

to buildings, walls, cliff carvings, coins, etc.

In the earliest days, "things are written down by things" or "things are debited", that is, things to be recorded are replaced by things that are easier to carry, but at this time all "things" are things in the real sense.

Counting fingers, knotting ropes, replacing stones, drawing on cave walls.

After that, bamboo slips, wooden slips, metal container surfaces, silk, silk, and Cai Lun paper were all commonly used methods and materials to store information.
