services can be implemented either by command or by graphical means:(1). Command mode: In character mode you can use the command to set the turn on or off service, the setting command is: NTSYSV, after executing the command as shown:Use the cursor keys or mouse to move the scrollbar to the service item you want to set, press SPACEBAR or click the option box with the mouse, select * indicates, if you do not need the service, then press the SPACEBAR or click the option box with the mouse, no symb

, there are various interrupts, and the system call is bound to the 0x80 interrupt. When a system call is called, an int 0x80 is fired, and the interrupt handler learns which system call is being called by EAX. The reason for this is that the number of system calls is too large, the interrupt number is not enough , so

User Login SystemIn general, there are three ways users sign in: (1) Command line login (2) SSH login (3) Graphical interface login Linux shutdown:The correct shutdown process is: sync > Shutdown > Reboot > HaltExplain:Sync: Synchronizing data from memory to the hard diskShutdown: Shutdown instructions (You can use "man shutdown" to view the Help document)Eg

develop a good Linux operating habits. When you get into Linux, don't think about it in the way that Windows works, because there are really big differences between them, such as the memory management mechanism, the process mechanism, and so on, so, to put aside the thinking of Windows, Trying to tap into the unique potential of Linux with a new concept is essential for beginners. The most important thing is to be accustomed to the command line operation mode. Linux is a command line composed o

Operating System Concepts Learning note 15 memory management (i) backgroundMemory is the center of modern computer operation. Memory has a very big group of words or bytes, and each word or byte has its own address. The CPU extracts instructions from memory based on the value of the program counter (PC), which can cause further reads and writes to a specific memory address.A typical instruction execution cy
