driven. For unrecognized, it can be solved by loading Panasonic's Usbaspi.sys and Aspidisk.sys in Config.sys. 5. Why is a disk lost after loading Usbaspi.sys? This is because the driver resets the USB device, and the content in the IMG file on the usbcdrom is gone, and the solution is to load the IMG into memory, using grub4dos or Isolinux software. 6, load USB2.0 Drive, what to pay attention to? Mainly compatibility issues, some motherboards may not run grub4dos, some may not load usbaspi

can obviously see the CPU load and storage IO are relatively high. If you specify the SSD as the storage for the swap file, it is actually wasteful and requires at least the sum of the specified virtual memory for all VMs. And because these VMs are decentralized, it's cumbersome to manage. SSD Host cache can avoid the above problems, set up after the No tube, swap files are still built on the original storage, but as long as the memory overflow does not exceed the capacity of the SSD, such as 1

Consumers familiar with the hardware may know that in many DIY hardware, the speed of hard disk performance in the system performance has a greater impact. Among them, the size of disk disc and the speed of seek time is the most important impact on the performance of hard disk, but the introduction of SSD has been the hard drive of the various parameters of the "brain behind." SSD due to the use of flash memory particles as storage medium, no mechanical components, so do not consider the single

It reflects the semantic requirements that the data involved in a particular application must meet.6. The third paradigm 1NF: Each attribute is non-divided. The emphasis is on the atomicity of the column, that is, the column cannot be divided into several other columns. 2NF: If the relationship R is 1NF, and each non-primary attribute is fully functional dependent on th

In demanding performance environments, memory is more attractive than SSDs.Disk development in the 50 's, despite the increasing disk density, the core architecture of the disk is basically unchanged, or the robotic arm moving the head to the disc on the track to read data.After the mechanical disk, there is a solid state drive (SSD), the SSD has no moving parts, and I/O latency is low. Currently, most SSDs are implemented with NAND flash.SSDs have signific

My younger brother has limited technical skills, and mistakes and ignorance are inevitable. Please give your advice.Article 1: make fewer HTTP requests to minimize the number of HTTP request requests. 80% of user response time is wasted on the frontend. These times are mainly caused by downloading images, style sheets, JavaScript scrip

In this example, the function Saycolor () is defined outside the object, even if it does not belong to any object, or it can refer to the keyword this. The color property of the object's obj equals "red". When the call () method is invoked, the first argument is obj, w

. These times are mainly caused by downloading images, style sheets, JavaScript scripts, flash and other files. Reducing the number of request requests for these resource files will be the key to improving the webpage display efficiency.There seems to be a conflict here, that is, if I have reduced a lot of images, styles, scripts, or flash, then the web page will not be bald, so ugly? This is a misunderstanding. We just want to reduce the number as much as possible, but we do not mean it is comp

. Finally, the price issue is also your concern. A small company can reach the salary level I mentioned above. Because a small company is short of working staff, and there are usually not too many people to interview you, a large company is really about to enter and need to cheer up, unless you're lucky. ------------- Finally, let's take a look at the simple analysis. lz seems not very convinced .. It doesn't matter. As you say, if you want to change something, you will be encouraged. 1. Fi
