In the process of using Linux, you may encounter system clock and hardware clock inconsistency, that is, Date,hwclock--show see the clock is inconsistent. The Linux clock is divided into system clocks (systems Clock) and hardware (real time Clock, short RTC) clocks. The system clock is the clock in the current Linux kernel, and the hardware clock is the battery-p

With the continuous development of the Communication Industry, mobile terminals have evolved from a single call function to voice, data, images, music, and multimedia. For mobile terminals, there are basically two types: feature phone and smart phone) smartphones have the basic functions of traditional mobile phones and have the following features: scalability of open operating systems, hardware and software and support for third-party secondary devel

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

Linux core-hardware basics-Linux general technology-Linux programming and kernel information. The following is a detailed description. The operating system must work closely with the basic hardware system. It requires services that can only be provided by hardware. To fully understand the Linux operating system, you must understand some

The router system is a combination of hardware and software. The hardware can be an ARM kernel, MIPS kernel, PPC, or Intel CPU. This core part is equivalent to the CPU of the PC we use. A pc generally only needs one Nic, but the router needs multiple NICs. Currently, most PC NICs are connected to the CPU bus through the PCI bus, and all data exchange needs to be processed by the CPU. However, in the design
