How to mail the desktop?

The college holiday is coming, and I want to mail my desktop back! What should I do? Let me give you a detailed introduction to the desktop mailing method! I hope it helps you!

The first method of desktop mail, you'd better remove the motherboard first, wrap it in shockproof plastic (the kind with small bubbles) and seal it. One is shockproof, the other is waterproof and moistureproof, and then put the screws in a self-sealed bag.

Put all the internal parts of the main engine in the chassis, and then fill the remaining gaps with plastic foam, so that the weight will not be heavy and the seismic effect will be good.

In addition, it is suggested that the landlord use home delivery. It is estimated that around 40 yuan, the objects are relatively safe. If there is a monitor, use the original packaging of the monitor.

But be sure to write down the slogan with care or other slogans in big black letters, otherwise it will easily break down.

The second method of desktop mailing is express delivery. You can find a convenient courier company online, and then you can pack and fill out the form. Maybe you can call them, maybe you can call them at home. The cost is only thirty or forty yuan! Nowadays, express delivery is much better than post office service because of competition. You'd better find express delivery.

There is no special mail, and the computer is a valuable item, so it is best to choose the insured price. This is more secure.

For express delivery, just choose home delivery, which is much better than Shentong's attitude, but Shentong has many places to go. From Shanghai to Xuzhou, you can consider home delivery.

The third method of desktop mailing is to mail desktop computers, mainly to prevent violent transportation and moisture.

1. If the original packaging of the chassis is still there, it is better to use the original packaging, and the foam at the corners is not easy to damage. I really can't find the original packaging. Please put more newspapers in the box as a buffer.

It is best to cover the chassis with a big plastic bag. There is no such a big plastic bag. It can also be spliced with plastic wrap or small plastic bags to prevent rainwater from entering on the way.

3. If there is an independent graphics card, it is best to remove the independent packaging. The violent vibration on the road can easily damage the discrete graphics card on the machine.

History of computer development

1 generation: electronic tube digital machine (1946? 1958)

In hardware, vacuum tube is used as logic element and mercury delay line is used as main memory.

Electron tube digital computer

Electrostatic storage, magnetic drum and magnetic core of cathode ray oscilloscope; External storage uses magnetic tape. The software uses machine language and assembly language. The application fields are mainly military and scientific computing.

Its characteristics are large volume, high power consumption and poor reliability. It is slow (usually thousands to tens of thousands of times per second) and expensive, but it lays the foundation for the future development of computers.

The second generation: transistor digital computer (1958? 1964)

Hardware operating system, high-level language and its compiler. The application fields are mainly scientific calculation and transaction processing, and begin to enter the field of industrial control. Its characteristics are smaller size, lower energy consumption, higher reliability, faster operation speed (generally 654.38+ million times per second, up to 3 million times), and its performance is better than that of 654.38+0 generation computers.

The third generation: integrated circuit digital computer (1964? 1970)

In terms of hardware, small and medium-sized integrated circuits (MSI, SSI) are used as logic elements, and the magnetic core is still used as main memory. In terms of software, there are time-sharing operating systems and structured and large-scale programming methods. It is characterized by faster speed (usually millions to tens of millions of times per second), significantly improved reliability, further reduced price, and products moving towards universality, serialization and standardization. The application field began to enter the field of word processing and graphic image processing.

Fourth Generation: Large Scale Integrated Circuit Machine (1970 to present)

In terms of hardware, logic elements are large-scale and very large-scale integrated circuits (LSI and VLSI). In software, database management system, network management system and object-oriented language have appeared. Its characteristic is that 197 1 year, the world's first microprocessor was born in Silicon Valley, USA, which initiated a new era of microcomputers. The application fields are gradually moving from scientific calculation, transaction management and process control to family.

Due to the development of integration technology, semiconductor chips are more integrated, each chip can accommodate tens of thousands or even millions of transistors, and the arithmetic unit and controller can be concentrated on one chip, thus a microprocessor appears, which can be assembled into a microcomputer with large-scale and ultra-large-scale integrated circuits, that is, a microcomputer or a pc. Microcomputer is small, cheap and easy to use, but its function and operation speed have reached or even surpassed that of large computers in the past. On the other hand, various logic chips made of large-scale and very large-scale integrated circuits are made into giant computers, which are not very large, but the operation speed can reach 100 million times or even billions. In China, after 1983 successfully developed the Galaxy I supercomputer with 1 billion operations per second, 1993 also successfully developed the Galaxy II universal parallel supercomputer with1billion operations per second. This period also produced a new generation of programming languages, database management systems and network software.

With the change of physical components and equipment, not only the host has been upgraded, but also its external equipment is constantly changing. For example, external storage, from the initial cathode ray display tube to the magnetic core and drum, and then to the universal disk, now has a smaller, bigger and faster read-only CD? ROM).
