Collect computer information for me, who has a computer to help me search for information

1.Information is the sum of the laws of motion of matter. Information is a universal form of the state and movement characteristics of objective things, and a large number of various kinds of information expressed in these ways exist, produce and transmit in the objective world.

The purpose of the information is to "remove the element of uncertainty". Information-related information: ** Information (also known as information), also known as information, is a type of message, usually in the form of words, sounds, or images, and is the result of data arranged in meaningful associations.

Messages are made up of meanings and symbols. Literature is a type of information, that is, the information that is commonly referred to as literature. Information refers to the actual content expressed in the form of sounds, words, words, images, animations, smells, etc.

Carrier of information: Information displayed on a computer screen 4There are ten basic characteristics of information:

Measurable. Information can be measured in a unit of measurement and encoded. Binary as used by modern computers.

Recognizable. Information can be grasped in a variety of ways, such as visual identification, comparative identification and indirect identification. Convertible.

Information can be transformed from one form to another. For example, natural information can be converted into forms such as language, words and images, and can also be converted into electromagnetic signals and computers**. Storable.

Information can be stored. The brain is a natural memory of information. Text, photography, audio and video recordings, and computer memory invented by human beings can all be used for information storage.

Manageable. The human brain is the best information processor. The thinking function of the human brain can carry out a variety of information processing activities such as decision-making, design, research, writing, improvement, invention, and creation.

Computers also have information processing capabilities. Transitive. The transmission of information is carried out simultaneously with the transmission of matter and energy.

Language, expressions, movements, newspapers, books, radio, television, etc. are commonly used by human beings to transmit information. Renewable. Once the information has been processed, it can be regenerated in other forms.

For example, natural information can be generated by means of language or graphics after manual processing. Various data and text and other information can be input into the computer, and the information can be generated by displaying, printing, drawing, etc. Compressible.

Information can be compressed, and the same thing can be described with different amounts of information. People often describe the main characteristics of a thing with as little information as possible. Available.

Information has a certain degree of effectiveness and availability. Shareable. Information is diffuse and therefore shareable.

Trouble, thanks!

The questioner adopts **Method: Laboratory**Method: Ordinary dry batteries are cylindrical, and the outer cylinder is made of zinc, which is the negative electrode of the battery; The carbon rod is the positive electrode; The barrel contains manganese dioxide, ammonium chloride and zinc chloride.

The following are two ways to utilize the substances in waste dry batteries:

1) Extraction of ammonium chloride: the black substance in the battery is stirred and filtered in water, and part of the filtrate is evaporated in an evaporation dish to obtain a white solid, which is then heated to collect purer ammonium chloride by "sublimation".

2) Preparation of zinc grains: cut the zinc sheets on the zinc cylinder into pieces, put them in a crucible with strong heat (zinc melting point 419 degrees), and carefully pour the zinc sheets into cold water after melting to obtain zinc grains.

Industrial method: There are roughly three ways to dispose of waste batteries in the world: solidification and deep burial, storage in waste mines, and utilization.

1. Solidify and bury deep and store in abandoned mines.

For example, a factory in France extracts nickel and cadmium from it, which is then used to make steel, and cadmium is reused to produce batteries. The rest of the waste batteries are generally sent to specialized toxic and hazardous landfills, but this is not only too expensive but also wasteful, because there are still many useful substances that can be used as raw materials.

2 **Utilization.

1) Heat treatment.

In Switzerland, there are two factories that specialize in the processing of used batteries, and the method used by the company is to grind the old batteries and then send them to the furnace to be heated, at which point the volatile mercury can be extracted, and when the temperature is higher, the zinc also evaporates, which is also a precious metal. Iron and manganese are fused to form an iron-manganese alloy for steelmaking. The plant can process 2,000 tonnes of waste batteries a year, producing 780 tonnes of ferromanganese alloys, 400 tonnes of zinc alloys and 3 tonnes of mercury.

The other plant extracts iron directly from the battery and uses a mixture of metals such as manganese oxide, zinc oxide, copper oxide and nickel oxide directly as metal scrap**. However, heat treatment methods are more expensive, and Switzerland also requires a small fee for each battery buyer to process used batteries.

2) "Wet treatment".

A "wet treatment" plant is being built on the outskirts of Magdeburg, where all types of batteries, except for lead-acid batteries, are dissolved in sulphuric acid and then extracted from the solution with the help of ionic resins, resulting in a raw material that is purer than heat treatment and therefore more expensive on the market, and where 95% of the substances contained in the batteries can be extracted. Wet processing eliminates the need for sorting (which is a manual process that increases costs). With an annual processing capacity of 7,500 tonnes, the plant in Magdeburg is slightly more expensive than landfills, but valuable raw materials are not discarded and do not pollute the environment.

3) Vacuum heat treatment method.

The vacuum heat treatment method developed by the German company Alter is cheaper, but this first needs to sort out the nickel-cadmium battery in the waste battery, the waste battery is heated in a vacuum, in which the mercury evaporates quickly, and then the remaining raw materials are ground up, the metallic iron is extracted with magnets, and then nickel and manganese are extracted from the remaining powder. The cost of such processing of one ton of waste batteries is less than 1500 marks. (Copied from, helped you, will be scolded for flooding).

A computer is a machine that uses electronic principles to process data according to a series of instructions. A computer can be divided into two parts: a software system and a hardware system.

The first computer was the ENIAC general-purpose electronic computer born at the University of Pennsylvania in the United States on February 15, 1946.

People refer to computers without any software installed as bare metal. With the development of science and technology, some new types of computers have emerged: biological computers, photonic computers, quantum computers, etc. On May 24, 1954, the transistor electronic computer was born.
