Computer as one of our daily use equipment, once the occurrence of such a fault, we can imagine the trouble, especially some rookie friends, once the failure of the hands of the work can not be completed on time, their own blind toss and fear of damage to the hardware equipment, maintenance and bear economic losses. In fact, we do not have so much trouble, computer problems are often a small number of glitches, learn some simple

1. System time and hardware timeThere are two clocks of hardware clock and system clock in Linux. The hardware clock is the clock device on the motherboard, which is usually the clock that can be set on the BIOS screen. The system clock refers to the clock in the kernel. All Linux-related instructions and functions are programmed to read the system clock. Because

To understand how the Linux kernel works, you have to know a little bit about the basics of hardware. Here we introduce the functions of several registers in the core components of the Intel 80x86 Series CPU protection mode, which play a vital role in the Linux kernel runtime. As for the other types of hardware, we introduce the device drivers to specific drivers. First, let's look at the main CPU architect

mistakes and errors, but since sharing out, is to let everyone and I together quweicunzhen, to improve. So I hope that we can make more suggestions and work together. Because memory management is a relatively abstract knowledge, it is based on three principles:(1) with a number of questions to study, to raise some questions, from these points of doubt into(2) Drawing the abstract knowledge into a logical diagram to make the frame clearer(3) instantiation, as far as possible by the actual equipm
