Five categories of operating systems, five management functions, and five Operating Systems Generally, the operating system can be divided into five management functions: 1) device management: it is mainly responsible for the data interaction between the kernel and periphera

The computer system consists of two parts: hardware and software, the operating system (os,operating system) is the first layer of software configured on the computer hardware, it is the first expansion of the hardware system. It occupies a particularly important position in computer systems, and other system software, such as assembler, compiler, database manage

The main difference between 32-bit and 64-bit in computer operating systems is that 32-bit in computer operating systems Windows 7 started after the Windows XP system. If you often pay attention to and install software, you will often hear 32-bit and 64-bit. What does this mean? What are their differences? Generally

considered. Generally speaking, there is a certain regularity in the number of movies. Usually for n movies, the hit rate of the nth movie is usually c / n where n is N,c is a constant. Meet C /1+C /2+C /3+...+C /N =1 Such a condition.In general, file storage on a video server satisfies the organ distribution. This allows the head to remain in the center of the disk in practice to reduce the time of movement.7.7.5 storing files on multiple disksOf course, yo

; multics-> Unix-LinuxCore ideas, Technology The user executes the program to use the computer (the idea of matching von Neumann) As a manager, the operating system to make a number of programs reasonable advance, is the process management Multi-process (user) push requires memory reuse, etc.Multi-process structure is the basic Atlas of operating system!for

, but can be cleared. The method is as follows:Right-click system on the left and select clear all events ".What is log management in the operating system? System logs are derived from marine logs: When people go overseas, they always need to make marine logs so as to provide a basis for future work. As a special file in Microsoft Windows operating systems, log f

explanation for you. First, this map is the Baidu Encyclopedia for reference, I modified a bit:First, the machine starts, loading the first sector of the disk 512 bytes of content to determine whether it is the startup program. And our disk image file corresponding to the first sector of the Assembly address is 0-0x200, that is, 512 bytes, the start is to read the 512 bytes, this is not the key, the key is that we start from the second sector of the disk to load the contents of the disk into me
