Many people, including me, have dreamed of rewriting Linux to become the Chinese operating system. Last year's "Computer" (36th "Linux Thought") once published in this regard: the use of C + + rewrite the Linux kernel and xwindows, to overcome the Linux to the common user too professional disadvantage, make it easy to install, easy to install and configure peripherals, Has a user interface that is as frie
NetDrive device are dedicated and optimized to ensure high reliability. In addition, the system software is solidified to prevent virus attacks. Because the NetDrive device is plug-and-play, you can install any device on the network as needed. Cross-platform and network: NetDrive supports multiple customer platforms,
Because of the hardware configuration, Internet cafe machines install different operating systems based on the hardware configuration of different machines. At present, Internet cafes have seen coexistence of Windows 98, Windows 2000, and Windows XP operating systems. In the face of these operating systems, interconnection has become a major challenge.

speed. Distributed operating system structure is also different from other operating systems, it is distributed in the system of the various computers, can be parallel to the user's various needs, has a strong fault-tolerant ability.⑥ Intelligent Operating System3. Analysis
The embedded system's requirements for execution speed and system reliability determine that an embedded system requires a safe and fast storage device, this kind of equipment also requires features such as small size, large capacity, and no loss of power-down data. Flash memory can meet the above requirements. This also makes flash memory the main storage device in the embedded system.Now Flash technology
