Super Weapon Exchange System

Qin Guan's sudden visit to Hanxin Technology Company surprised the leaders of the company. Lisa has been stationed in Eagle Country frequently, and the person in charge of Hanxin Technology Company is still Zhang Gong.

After sending away the guests from the Date Palm Country, Qin Guan came. When Qin Guan arrived, Zhang Gong was holding work meetings of various subordinate departments.

Although Hanxin Technology is already a world-class company, it still lacks in many aspects. For example, the development of memory restricts the development of the entire computer system.

Back then, in order to avoid the limitation of hard disk technology, Hanxin Computer decided to adopt the form of optical disk. The optical disk can store hundreds of megabytes of data, which perfectly solved the problem. The computer does not even need a hard disk. Use the optical disk to start the computer and start the software. Use a floppy disk to copy data, and it can be used normally.

However, this is just an alternative. The hard disk is still an indispensable part of the computer system. Therefore, Hanxin Technology also established its own R&D department at that time and began to develop supporting hard disks.

In later generations, there is an argument that the market is global, and you don't need to be comprehensive, as long as you do what you do best, that's enough.

So, what are you best at? If it is assembly, then it will be assembled and become a world-class assembly factory. That's not bad. People are good at chip research and development, so let them go.

Without those despicable political goals, a globalized industry is good. It can minimize costs and increase the creativity of all mankind. However, once dirty politicians are mixed in, it will be different. Cut off one of your supplies and the assembly plant will be over.

Even chip manufacturers, if they can’t be completely autonomous and rely on others for some of the raw materials, they will have terrible consequences. I can't move on.

It's so cruel.

Hanxin Technology Company absolutely does not tolerate being controlled by others. Everything must be autonomous. Hard disks do not have too high technical content. How can it be difficult to get us? As long as the know-how is mastered, it is easy to greatly improve its performance.

"Now, we have perfectly mastered the magnetoresistive technology in hard disks. Our new generation of hard disks has a capacity that can rise to GB level, and its size is only as big as this box."

In order to develop hard disk technology, Hanxin Technology Co., Ltd. has established a dedicated R&D team. Now the hard disk capacity has reached the GB level, which is already a major improvement!

Moreover, it is no longer the size of a cabinet, but a box the size of an optical drive that can be directly packed into the main box.

Now it's the storage department's turn to speak. They are proud of their research and development results. They used to be controlled by others in hard disk technology. Now they can finally stand on the commanding heights of the industry.

"Yes, we have reached the GB level now. Everyone should stop being impatient and irritable, and continue to research and develop carefully. After that, it can be 10G, 100G, or even TB level."

Now, when these goals are mentioned, everyone present feels a bit unbelievable. TB, how could this happen? It is impossible to make the data density of the current hard disk a thousand times higher. Will the magnetic pole not interact with the adjacent magnetic pole, and then data confusion will occur?

Qin watched the disbelieving eyes of the people present, and continued: "Technological progress has been earth-shaking. Just before, for example, five years ago, would we think of having GB-class desktop hard drives?"

Five years ago, it was good to have a desktop hard drive of several tens of megabytes. I didn't dare to imagine a gigabyte. Now, it has come out. After the successful magnetoresistive technology, the storage density of the hard drive has greatly increased.

In the future, there will be any advanced technology that will allow the capacity of hard drives to increase by leaps and bounds.

"Of course, we not only need advanced hard drives, we also need more advanced technology to prevent the loss of hard drive data."

For ordinary users, if the hard disk data is lost, such as the game progress is gone, then play again. However, if it is a commercial user, the stored data must not be faulty, such as the banking system, losing customer data , That's pretty good!

"For industrial users, I decided to use disk array technology." The person in charge said that in the past, hard disks were quite expensive, so it was impossible to build such an array, but now, with the rapid development of hard disks Development, this kind of hard disk of our own, with large capacity and low cost, it is possible to form an array.

A research team at the University of California at Berkeley in Eagle Country published an article just this year, inventing the term RAID, and defining the five levels of RAID.

At that time, they were studying how to improve the read performance of the disk. Two hard disks were used to store data separately and read them together. This would increase the speed and save the computer waiting to read the data. This method is RAID0. Of course If you want to pay attention to data, you can store and modify the same data simultaneously on two hard disks, so that you can achieve fault tolerance and logical data backup capabilities.

However, they are only studying theories, and turning the theory into reality has to rely on the team of Hanxin Technology Company. They have now started to develop this technology and upgrade the hardware and software simultaneously. In this way, the two hard drives have errors at the same time. The probability is very small, even if it makes a mistake, it is impossible to make a mistake in the same location, so that the data on the hard disk can be best protected.

"I'm not just talking about this. For example, some programs deliberately delete hard disk data maliciously, or copy a lot of meaningless content?" Qin Guan said.

"Are you talking about a computer virus?"

"Yes, it is a computer virus. It can not only destroy the data in our hard disk, but it can also reproduce itself, spread to other computers through the network, and the computers in the entire network will be infected. It can cause a lot of uselessness. The sending of data packets causes the network to be paralyzed and useful data cannot be transmitted. Of course, it is not only in these software fields, it may even damage computer hardware."

When it comes to software threats, everyone can agree, how can the hardware be destroyed?

Qin Guan continued: "With the development of technology, our computer needs to read data from the BIOS when it starts. Moreover, this data can be continuously updated and can be flashed. If there is a virus, If you can flash it, as long as you inject irrelevant data, the computer system will be completely destroyed and the hardware will be unusable."
