Super Weapon Swap System

Qin Guan's sudden visit to Hanxin technology company surprised the company's leaders. Lisa has often been stationed in Yingguo. Zhang Gong is still the person in charge of Hanxin technology company.

After seeing off the guests from the date country, Qin Guan came. When Qin Guan arrived, Zhang Gong was holding a working meeting of various subordinate departments.

Although Hanxin technology company is already a world-class large company, it is still deficient in many aspects. For example, the development of memory restricts the development of the whole computer system.

In those years, 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 doesn't even need a hard disk. It can be used normally by starting the computer with optical disk, starting software and copying data with floppy disk.

However, this is only an alternative. The hard disk is still an indispensable part of the computer system. Therefore, Hanxin technology company also set up its own R & D department 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 are best at, that's enough.

So, what are you good at? If it's assembly, it's good to be a world-class assembly factory. People are good at chip R & D, so they let them do it.

Without those despicable political purposes, globalized industry is good, which can minimize costs and improve the creativity of all mankind. However, once dirty politicians are mixed, it will be different. As long as the other party cuts off one of your supplies, the assembly plant will be finished.

Even if the chip production enterprises can't be completely independent and rely on others for some raw materials, there will be terrible consequences. For example, the kimchi country is placed on hydrogen fluoride by the island country, and its huge electronic industry can't start.

It's so cruel.

Hanshin Technology Co., Ltd. absolutely can't stand being controlled by others. Everything should be independent. How can it be difficult for us to get the hard disk without too high technical content? As long as you master the know-how, it is easy to greatly improve its performance.

"Now, we have perfectly mastered the magnetoresistance technology in the hard disk. The capacity of our new generation of hard disk can rise to the GB level, and its size is only as big as this box."

In order to develop hard disk technology, Hanxin technology company has established a special R & D team. Now the capacity of hard disk has reached the GB level, which is a major progress!

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

Now it's the storage department's turn to speak. They are proud of their R & D achievements. They used to be controlled by others in hard disk technology. Now, they can finally stand at the commanding height of the industry.

"Yes, we have reached the GB level now. We should stop being impatient and continue careful research and development. In the future, it can be 10g, 100g or even TB."

Now, when it comes to these goals, everyone present feels a little incredible. TB, how can this happen? It's impossible to increase the data density of the current hard disk a thousand times. Those magnetic poles won't interact with the adjacent magnetic poles, and then there will be data confusion?

Looking at the unbelieving eyes of the people present, Qin Guan continued: "the progress of technology is earth shaking. Just in the past, for example, five years ago, would we think of having a GB desktop hard disk?"

Five years ago, it was good to have a desktop hard disk with tens of megabytes. I can't imagine a GB level. Now it has come out. After the success of magnetoresistive technology, the storage density of hard disk has greatly increased.

In the future, what advanced technology will make the capacity of hard disk advance by leaps and bounds.

"Of course, we should not only have advanced hard disk, but also have more advanced technology to prevent the loss of hard disk data."

For ordinary users, if the hard disk data is lost, for example, if the game progress is not available, then play it again. However, if it is a commercial user, there must be no error in the stored data. For example, if the banking system loses the customer's data, it's OK!

"In terms of industrial users, I decided to adopt disk array technology." the person in charge said that in the past, hard disks were very expensive, so it was impossible to set up such an array, but now, with the rapid development of hard disks, it is possible to set up an array with large capacity and low cost.

A research group at the University of California at Berkeley in Eagle Kingdom published an article this year, invented the word raid and defined the five levels of raid.

At that time, they studied how to improve the reading performance of the disk. They used two hard disks to store data separately and read together, so as to improve the speed and save the computer from waiting to read data. This method is raid0. Of course, if you want to pay attention to data, you can store and modify exactly the same data on the two hard disks synchronously, In this way, the ability of fault tolerance and logical data backup can be achieved.

However, what they study is only theory. To turn theory into reality, they have to rely on the team of Hanshin technology company. Now they have begun to develop this technology and upgrade the hardware and software synchronously. In this way, the probability of two hard disks making mistakes at the same time is quite small. Even if they make mistakes, they can't make mistakes in the same location, This will best protect the data on the hard disk.

"I'm not just talking about this. For example, some programs deliberately and maliciously delete hard disk data 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 also reproduce itself and spread to other computers through the network. Computers in the whole network will be infected. It can cause a large number of useless data packets to be sent, resulting in network paralysis and useful data can not be transmitted. Of course, it is not just these software In the field, it may even damage computer hardware. "

When it comes to software threats, we can also agree that how can hardware be destroyed?

Qin Guan continued: "with the development of technology, when our computer starts, it needs to read data from the BIOS. Moreover, this data can be continuously updated and can be written. If there is a virus that can be written, as long as irrelevant data is injected, the computer system will be completely destroyed and the hardware can not be used."
