the output device.Output device: A device that outputs information from a computer to a user. Commonly used input devices are: monitors, speakers, printers, projectors and so on We buy computer, if only keyboard mouse, monitor, speaker, we can play computer? Definitely not. So in fact, the computer chassis is the real work of the device, input just used to let us and the computer chassis to do the interaction.What's inside the chassis? Let's take a look at the following picture:Let's see

In Linux, you can view CPU and memory usage during system maintenance. You may need to view CPU usage at any time and analyze the system status based on the relevant information. In CentOS, you can use the top command to view CPU usage. After the top Command is run, the CPU usage status is displayed in full screen mode

first, the CPU cache structureCPU speed is much higher than memory (that is, if only CPU and memory factors are considered, the performance of the program is often limited by memory access speed, memory access and operation), in order to reconcile the CPU and the difference in the speed of the internal, the CPU has bee

CPU in the computer running process will be hot, if not timely cooling, with the accumulation of heat caused by burning the CPU. This requires the configuration of the CPU fan exhaust fans to speed up the flow of air through the fan, the heat emitted in time. While the CPU fan has a thermal sensor, when the temperature

Interrupts are actually signals sent by hardware or software called IRQ (Interrupt request).Interrupts allow devices such as keyboards, serial cards, and ports to indicate that they require a CPU.Once the CPU receives the interrupt request, the CPU temporarily stops executing the running program and invokes a specific program called the interrupt processor or interrupt Service program (interrupt service rou

subsystems are mounted by default.Cgroup Subsystem IntroductionOf course, the user can customize the subsystem and mount it.The following is a brief introduction to each subsystem: The Blkio setting restricts the input and output control of each block device. For example: disks, CDs, USB, and so on. The CPU uses the scheduler to provide CPU access to the Cgroup task. CPUACCT generates

As the core component of the computer, the CPU (central processor unit) has been very mysterious in the hearts of users: in the minds of most users, it is just an abbreviation, they cannot even write all of it. In the eyes of some hardware experts, the CPU is at most a block of more than 10 square centimeters, with many feet, the CPU core is less than 1 cm² large

Physical encapsulation of the CPU, a physical package using a separate CPU physical slot, sharing power and fans;CPU Physical Core: Encapsulates multiple independent CPU cores in a physical package, each with its own complete hardware unit.CPU Logic Core: A CPU physical core

Problem: I have a Linux process running on a multi-core processor system. How can I find out which CPU kernel is running the process? The affinity of Cpu/memory is one of the most important factors for maximizing performance when you run HPC (High performance computing) programs that require higher performance on multicore NUMA processors or programs that consume network resources very well. Scheduling

Linux is available under the top, PS command to check the current CPU, mem usage.

Believe that a lot of computer users are too high CPU temperature problems, then, many netizens will ask, in the end, how much CPU temperature is normal.

This blog post focuses on the features and functions of the CPU registers around the base part of the registers in the 80x86 CPU.ObjectiveFirst, let's introduce the history of Intel CPUs.Intel CPU Series, initially 4-bit microprocessor 4004, then to 8-bit microprocessor 8008, then 8-bit microprocessor 8080, and later 16-bit microprocessor 8086.Starting from 8086, Intel entered the so-called x86 era.Intel 80

CPU usage depends primarily on what kind of resources are running on the CPU, such as copying a file that typically consumes less CPU, because most of the work is done by DMA (Direct Memory Access), but after the copy is complete, the CPU knows that the copy has been completed. Scientific computing usually takes up mor
