Linux? First, let's explain what an operating system is. Simply put, an operating system is a set of system software that runs on top of hardware and provides various services for us. For example, the content displayed on the screen is controlled by the operating system's video card and screen display. The various services we use at ordinary times are also related to the operating system's control hardware (video card, Nic, sound card, hard Disk. Some people say no. We use browsers,

The early Whois query was more of a command-line interface, but now there are some web interface-Simplified online query tools that can be queried at once to different databases. Web interface query tools still rely on the WHOIS protocol to send query requests to the server, command-line interface tools are still widely used by system administrators.

Shell Variable Function (1) Shell variable function: the so-called variable is to replace a complicated and easy-to-change data with a simple thing. The so-called environment variable is that when we log on to a user name correctly, the system gives us a bash execution program so that we can truly communicate with the system through bash, the system needs some variables to provide access to its data (or set the parameter values of some environments, s

Almost all of the object instances are allocated memory here. The Java heap is the primary area of garbage collection management. So the Java heap is also called the "GC" heap (garbage heap). Java heap Refinement, the new generation and the old age. is to better reclaim memory and allocate memory

The slow shutdown of Windows 2000/xp has been a dull pain for many users, so someone has explored the following "abnormal" skills.If you want Windows 2000 to restart at an instantaneous rate, you can press the Ctrl+alt+del key combination and hold down CTRL while you click the "Shutdown" button, and the warning prompts: "If you continue, your machine will reboot and the unsaved data will be lost. If not absolutely necessary, do not take this step ", click" OK ", then Windows 2000 will be restart

What is Shell?This should be an interesting topic: "What is Shell ?』 I believe that most of my friends who have been familiar with computers and have heard of the concept of a job system, whether it is Linux, Unix or Windows. As long as they have a "job system", Shell is indispensable. However, before discussing Shell, let's take a look at the computer's operation status! For example, when you want a computer to transmit "Music", what does your computer need?

IIS (w3pw.exe) occupies a high cup (high), it is a little outrageous, or even very high in an instant) if so, we should look at the code, which is highly suspected of endless loops. 2. Database optimization mainly involves indexing, query statements, stored procedures, and ASP code. 3. You can create an application pool for IIS to achieve optimization. 4.

, common is Secure Shell. To use Telnet, you must specify the command to start the Telnet client and the name of the target host. In Linux, you can: $ Telnet internic.net This command starts the Telnet process and connects to internic.net. The connection may be accepted or rejected, which is related to the configuration of the target host. In UNIX, the Telnet command was built in a long time ago. That is to say, Telnet has been included in the UNIX release version for ten years. However, not all
