surge protector is not enough to protect your system from the destruction of "dirty electricity. Remember, UPS plays a key role in protecting your hardware and data. 10. monitor whether the security of the system is threatened and intruded. Never think that, because you have taken a series of security protection measures, your system will not be infiltrated by the Security breaker. You should set up some types of monitoring programs to ensure that su

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

to consider when installing software. If you use a 32-bit software, there may be many incompatibility issues. This is why many people spoke about Windows 7 when its 64-bit version was just released. If you use a 64-bit CPU and a 32-bit operating system, it may not be a problem, but it may also cause problems because of backward compatibility. If your CPU is 32-bit, it can be controlled at most when the CPU controls the memory. Power 32 of 2 = 42949

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

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

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
