Java is an object-oriented programming language that allows you to write cross-platform applications. It was released by Sun Microsystems in 1995. Java has excellent versatility, efficiency, platform portability and security. It is widely used in personal PCs, data centers, game consoles, scientific supercomputers, mobile phones and the Internet, it also has the largest developer community in the world. In the global cloud computing and mobile Interne

The kill command works by sending a system operation signal and the process ID of a program to the Linux kernel. Then, the system kernel can operate the process specified by the process ID number. For exampleTopCommand, we can see that the system runs many processes, sometimes you need to use kill to stop some processes to improve system resources. When explaining the installation and login co

When explaining the installation and login commands, I mentioned that the role of multiple virtual consoles in the system is to switch to other virtual consoles to close the program when a program error causes a system deadlock

color palette image does not have bitwise operations in 16-bit colors to extract RGB colors, but it is often confusing to developers, the color will be messy if the color palette is used. However, in our old game consoles and old games, it earned a lot, because in the time when the hardware was expensive, the color palette was one of the most memory-saving display methods. Therefore, the images of game consoles
