USB flash drive and all types of Flash Cards (SmartMedia =SM card, Compact Flash = CF card, MultiMediaCard = MMC card, Secure Digital = SD card, Memory Stick) have long been used on a large scale and widely available, but they have some other applications besides being storage devices. For example: As a boot disk for Windows PE OS, as a system installation disk, as a replacement for various Live CDs, and so forth. Today we are going to talk about using USB flash drive (Flash Card needs to cooperate with the card reader to work the same way) as a key for locking/unlocking your computer with ease.

In this age of computer + Internet, many of our jobs are computer dependent, even require us to sit in front of computer for a long time. As we all know, computer does a lot of harm to our health in many ways. One of them is that the large amount of harmful blue light emitted from display can damage our retina, thus leading to maculopathy and cataract, causing asthenopia (eye strain), and leading to poor sleep quality and even insomnia.

As we all know, the greatest benefits of the image file format are security, stability, and high compression. Therefore, many collectable files are made into ISO or other image file formats for preservation and distribution. Instead of burning an image file as a CD/DVD as before in order to view the files inside, you can always use a file archiver like 7-Zip to direct extract them out (which can be time-consuming), but a better way to do that is use a virtual drive.

As we all know, Freenet famously led to the popularity of the dark web before Tor was released. Today, there have been many dark web systems, large and small. Freenet, Tor and I2P are known as the three giants in dark web, and thereinto Tor has the largest user base. In essence, Tor (short for The Onion Router) is a free software designed to realize the anonymous Internet communication.

When we are playing some 3D games, the game may encounter problems such as picture jam, or even crash because the performance of our computer hardware cannot keep up with the demands of game. Of course, there are a lot of graphics card optimization software, such as Rivatuner, Nvmax, Rage3D, etc., but most of them cannot optimize all the graphics adapters in the market. More importantly, the traditional optimizer perform optimizations based on the architecture of graphics card itself, which at best makes the graphics card better play its own performance.
