Chapter 474: Recite the moral classics

A computer needs not only a central processing unit, but also memory, external memory, peripherals, and so on.
Many laymen will confuse memory and external memory, ask how much memory is there? Why is it 64G, too little, at least 256G, um, what the is running memory?
The memory in the computer means running memory. It is the place where data is temporarily stored when the CPU of the computer is performing various operations, so that the CPU can be used faster than external memory.
As for the external storage, it has undergone many changes. At first, magnetic drums were used, and then magnetic tapes. Now, it has developed into floppy disks.
Comparing the two, when the memory is powered off, the data is gone, while the external memory can still be stored for many years.
Later, it was hard disks, optical disks, and solid hard disks, and so on. The capacity became larger and faster.
In this era, the floppy disk is already the most advanced, and it is still a large floppy disk.
The world's first 5.25 inch floppy drive was developed by Shugart Associates in 1976 for IBM's mainframe. It was later used in IBM's early PCs. It was not until 1980 that Sony introduced a 3.5-inch disk. Since the early 1990s, 3.5-inch, 1.44MB floppy disks have been used as the standard data transmission method for PCs.
Therefore, the current floppy drives mainly use 5.25 inch floppy drives, and high-density floppy drives, also called 5.25 inch 1.2M floppy drives.
In Han, computers have not yet become widespread. Even in the capital, there is only one large electronic city selling such floppy disks. Therefore, Xiang Jing went back and forth and spent more than an hour.
When Xiang Jing came back, he saw that the scholar was communicating with Ni Gong and Zhang Gong, and the three people were actually communicating in Eagle language. The scholars were so fluent in professional terms.
It doesn't matter to you, as long as you can fool them.
Then Xiang Jing walked to the inner room and saw Qin Guan lying on the bed, reading a free book comfortably.
When Xiang Jing came in and took a look, it turned out to be a Tao Te Ching!
If someone from outside comes in, see how you explain!
"Okay, the floppy disk is available," Xiang Jing said.
"Well, put the floppy disk into my computer, I'm about to start outputting." Qin Guan lay down and said to Xiang Jing.
The sound is a bit loud, I guess everyone outside can hear it.
Then Qin Guan entered the system.
This time, head straight to the Intel headquarters!
As a high-tech company, will Intel use drawings to design? Just like the Wang Lao I saw, in order to design your own 4KB of memory, spread such a large piece of paper on the ground?
Definitely not. All their design materials must be stored. In this era, although hard drives have been invented, the storage capacity of hard drives is still quite low. Only later this year will they be able to have 571MB hard drives. At the same time, as a data backup, in this era, floppy disks are definitely the most suitable way to backup data.
Qin Guan guessed in this way, and then he pressed the select button to lock his needs in the selection of the weapon data graveyard system.
Intel Corporation is a civilian CPU company. Is their data considered weapon data?
Of course!
The army also uses computers. In addition to military notebooks that need to be reinforced, the army also has a large number of civilian computers for various operations. At the same time, some weapons directly use civilian chips.
Yes, that's it. The Eagle Country’s Tomcat fighter used the 8086 chip as the processor when improving its radar.
Therefore, these data are also in the weapon data cemetery!
Qin Guan cautiously walked into Intel’s data storage area. Before it started tossing, he heard the familiar voice: "My dear, the place you come in is different every time, so I have to look for you back and forth. Figure."
Qin Guan slowly turned around and looked at Lisa: "Sister, I found a book specially for you."
After that, Qin Guan has an extra book in his hands, the "Tao De Jing" that he was reading just now.
"Now, my brother gives you a task to memorize this book. Next time I come in, I need to check it," Qin Guan said.
Lisa was very curious when she heard Qin Guan's words. This seemed to sound very interesting.
"Okay, I will." Lisa solemnly accepted the book: "Next time you come, I will definitely recite it."
Qin Guan had already thought of a good way to avoid being like a thief every time he came in, simply being generous. This was the inspiration he got last time, and that was to find something for Lisa.
What are you looking for?
Of course it was for her to endorse. The culture of the Han country lasted for five thousand years. So many cultural treasures could be memorized by Lisa. Then, wouldn't it be easy for me?
Sure enough, after receiving the book, Lisa immediately opened the book and planned to start memorizing it.
Qin Guan was about to breathe a sigh of relief when suddenly there was another voice.
"Brother, if I had memorized this book, what reward would you give me?"
"What? A reward?"
"May I give you a candy?"
"No, I want a kiss from you."
Qin Guan suddenly grew his head again.
"I'll talk about it next time, I'm looking for something now." Qin Guan said, and began to search carefully.
In the 2020 data cemetery, Intel’s 80286 chip design data is definitely an old antique. After all, its performance is not as good as the processors in later generations of old machines. Fortunately, this big company has data management. It is also quite in place.
Finally, after three hours of searching, Qin Guan found a stack of floppy disks wrapped in a large envelope, 80286 detailed design materials!
Okay, that's you, the exchange begins!
In front of Qin Guan, some floating frames appeared. Qin Guan quickly pressed various buttons. At this moment, Lisa Lang Lang's reading sound came from behind: "Dao is Tao, very Tao; a name is a name, a very famous name. . Nameless, the beginning of all things, famous, the mother of all things...."
That’s great, you can go on to study morals, knowing that men who have already married are single-minded, and it’s not good to interfere in other people’s marriages.
The exchange starts!
In the space, a strange scene suddenly appeared. In the past, different exchanges and scenes were different. The exchange of weapons seemed to be a sudden crack in time and space. The weapons were replaced as a whole, and the exchange of information was like one. The pages of paper are flying, and now, the exchange of floppy disks, in the air, it seems that you can see countless 0s and 1s, in a long line, flying quickly towards the sky.
These are the most precious information!
