Nbsp; 1. basic knowledge: an operating system can be simply abstracted as a boot program kernel file system. Vmlinuz is an image file of the Linux kernel. it can be loaded by the boot program to start the Linux system. The full name of initrd is bootloaderinitializedRAMdisk, which is 1. basic knowledgeAn

case. Linux has powerful networking capabilities and its TCP/IP code is the highest level. Linux provides full support for the current TCP/IP protocol, and includes support for the next generation Internet protocol IPv6. The Linux kernel also includes IP firewall code, IP anti-counterfeiting, IP service quality control, and many security features. These features are comparable to those of high-end routing devices provided by Cisco and other companies. These application cases prove that Linux is

who don't like to explore have trouble writing their own operating system for entertainment. A programmer's requirements are different from that of a regular user, and the programmer needs to know about his computer, master it, and be skilled in getting it to do its job, and in this sense Unix has a huge advantage. Every tool inside it is sharp, you can use it for a long period of years, and it's not going

duplicating the root file system (ROOTFS) image and burning the file system, saving a lot of copies, transferring files, saving development time.How do I turn on the nfsroot feature? The following conditions are required to open the Nfsroot function:1. Host (typically a Linux system inside a virtual machine) to turn on the NFS Server service2. The network port o

onto their motherboard, such as LED lights. We have previously published a blog post describing how to attach an led to the Geeksphone Keon Firefox phone and control it. this stuff can run native code no ? You can use the Android ndk/toolchain to compile any binary code for the ARM architecture for the motherboard, and you can invoke the binary code using the Mozos.exec API. Please click to view examples. brother, does this thing save electri

Earlier, we used Debian as a server software and later turned to CentOS, mainly for the following reasons:1, Centos/rhel life cycle is 7 years, basically can cover the life cycle of hardware, also means that a new hardware installation, do not have to install the operating system again. Be aware that it is troublesome and risky to re-toss a production machine.[2012.2.1] just received a red Hat notification

Whether monitoring the performance of the system, or to explore the cause of the failure, the real key is to find the right tool. Open the XP All Programs menu, and there's a whole bunch of tools under System Tools for you to choose from. However, if you are an experienced user, Windows XP has another big gift package for you: There are more than 100 different tools hidden on the installation CD. They cover

In recent years, with the rapid development of embedded systems, embedded real-time operating systems are widely used in the manufacturing industry, process control, communication, instrumentation, automobile, ship, aerospace, military, equipment, and consumer products. Nucleus PLUS is a preemptive multi-task operating system kernel designed for real-time embedde
