Chapter 314 (2/2)

Bao Zixuan smiled and said, ”I'm writing a software, specifically a compression software.”

At this time, everyone is curious about what compression software is. But they have never heard whether this boy wants to develop any new technology. This is a business opportunity.

Huo Yingdong said: ”what is compression software? We are all laymen of computers. If it's convenient for Bao Sheng, can we popularize it with us. Otherwise, you won't be able to chat on one channel next time. ”

As the organizer of this event, Huo Yingdong should always liven up the atmosphere and make everyone feel very fruitful. In this way, more and more talents will come in the future.

Bao Zixuan: ”most of what we do with computers is to process files. Each file will occupy a certain amount of disk space. We hope that some files, especially those that are not used temporarily but are important and cannot be deleted (such as backup files, which are a bit like chicken ribs), will occupy as little disk space as possible. ”

”However, the storage format of many files is relatively loose, which wastes some valuable computer storage resources. At this time, we can solve this problem with the help of compression tools. By compressing the original files, we can save them with less disk space, and then decompress them when they need to be used, so as to greatly save disk space. When you want to copy many small files, compression can improve execution efficiency. If there are many small files, it takes a lot of time for the operating system to perform frequent file location operations. ”

”It is convenient to compress these small files into a compressed file and then copy them. Because the information processed by the computer is expressed in the form of binary numbers, the compression software is to mark the same string in binary information with special characters to achieve the purpose of compression. In order to help understand file compression, please imagine a picture of blue sky and white clouds in your mind. For thousands of monotonous and repeated blue image points, instead of defining a long string of colors of ”blue, blue, blue...”, it is better to tell the computer: ”store 1117 blue image points from this location”, which is more concise and can greatly save storage space. This is a very simple example of image compression. In fact, in the final analysis, all computer files are stored in the form of ”1” and ”0”. Like blue dots, the volume of files can be greatly compressed through reasonable mathematical calculation formulas to achieve the effect of ”lossless and dense data”. Generally speaking, compression can be divided into lossy and lossless compression. If the loss of individual data will not have much impact, it is a good idea to ignore them. This is lossy compression. ”

”To put it bluntly, I have a letter in my hand now. It's full of words. I can read them directly. But I want to convey these words to another person. At this time, I will send the letter to him. If the road is far away, what should I do! Just fold the paper in half a few times to make it take up less space so that I can put it in the envelope. After opening the envelope, the person receiving the letter must reopen the letter paper if he wants to read the information at the first time. This is the simplest working principle. My software can make the file smaller. When we need it, we can unzip it and restore it to its original appearance. In this way, the file transfer process will not occupy a lot of storage space, and there is no decompression software. Others can't see it; Information is also relatively safe. ”

Xiangjiang tycoons like listening to heavenly books know that they really don't understand this. However, I finally understand that I still need to study hard.

Not only the Xiangjiang tycoon, but also the crew did not understand. However, the young rich man is really knowledgeable. He knows such complex computer knowledge.

President Li said: ”Bao Sheng deserves to be the winner of the Turing Award. It is estimated that few people in the world can understand such a profound principle of operation. It seems that we can't keep up with it simply by learning. In the future, we should learn more about computer knowledge, otherwise we will really not be able to keep up with the development speed of the situation and the times in the future.

In fact, President Li has another idea in his heart, but it's not easy to say it in public now.
