Computer power supply is the hub of computer components, is an important part of the computer. The 220V alternating current is converted into DC power and transported to each component separately. Power classification 3.1 Pc/xt power supply IBM first launched a personal PC/XT machine set standards. 3.2 at power supply It was also the standard proposed by IBM early launch of

. The function of a PC fan is to accelerate air convection. In addition, water cooling and heat pipes can also be regarded as a form of convection. heat radiation, which is basically not used in PC heat dissipation. A common example in life is the reflector used by the heater to reflect heat. It should be noted that the electromagnetic radiation is irrelevant in peacetime. (Cut from the clip bar "the radiat

Under Linux/unix, CPU utilization (CPU utilization) is divided into user state, System State and idle state, respectively, the CPU is in user state execution time, system kernel execution time, and idle system process execution time. Usually referred to as CPU utilization refers to: the

Of the CPUs currently produced by Intel, Pentium 4 and Celeron are PC-oriented, Xeon, XEONMP, and Itanium are for workstations and servers. Where Itanium is a completely different 64-bit CPU from other CPUs, the design is not considered for existing Windows applications. While other processors vary in their maximum operating frequency, FSB (front bus frequency), and cache size, the internal design is essent

Understanding the system structure from the Java perspective serial, follow my Weibo (link) Learn about the latest developments it is well known that the CPU is the brain of the computer, which is responsible for executing the instructions of the program; Memory is responsible for saving data, including the program's own data. As we all know, memory is much slower than CPU. In fact, 30 years ago, the

In electronic technology, the pulse signal is a pulse signal continuously sent at a certain voltage range and at a certain interval. The interval between pulses is called a cycle, and the number of pulses generated per unit time (for example, 1 second) is called a frequency. Frequency is the metering name that describes the number of pulses that appear in a periodic cycle signal (including a pulse signal) per unit time. The standard unit of measurement for a frequency is Hz ). The system clock i

How does the CPU look at performance? This is a problem that friends of computer enthusiasts often ask. Today, the computer Pepsi network finally brought the CPU ladder Figure 2016 the latest version, through the latest CPU ladder diagram, can fully understand the computer processor performance. This provides 2016 of the latest

CPU Ladder Figure 2016 the latest version of the CPU how to see performance? How does the CPU look at performance? This is a problem that friends of computer enthusiasts often ask. Today, the script House finally brings up the latest version of CPU Ladder 2016, through the latest

One, wall clock time, user CPU time, System CPU time definition and contactClock time (Wall clock time): The time that the clock passes from the start of the process to the end, which contains the time at which the process is blocking and waiting.User CPU Time: Is the user's process to obtain the CPU resources after th

Knowledge about Linux CPU and Linux CPU What is the difference between hyper-threading and multithreading? Hyper-threading is understood from the hardware layer, that is, a CPU component (which can be understood as a core) executes multiple commands at the same time, which means that multiple threads are executed at the same time.Multithreading is a concept at th

If you are familiar with the current market notebook models, you will find that the mainstream of domestic notebook models of most of its capacity in more than 500GB, some models can even reach more than 1TB. And the reverse view is currently popular pc/plate two-in-one product, their capacity is almost all under 512GB, most of the capacity of the model only stay at the 64-128GB level, the performance of the capacity of a very need for s

How to view CPU configuration information in Linux, and how to view cpu configuration in linux Enter the command: cat/proc/cpuinfo Check the number of physical IDs in the output result. If 0 is displayed, there is only one physical cpu; Check the number of processor output results. If there are 0 and 1, there are two logical CPUs. (1) Concepts ① Physical

Now we have realized that in the PC design, the CPU is not executed in full accordance with the program instructions. Sometimes the device is interrupted manually or randomly, allows the CPU to execute the corresponding interrupt processing program to build a more intelligent hardware and software system. So what kind of Interrupt Processing System has the top co

As major internet companies move into the mobile market, the demand for mobile-end products is growing, and designers are moving more and more frequently between PCs and mobile designs. At present, many product planning is in the PC and mobile end-to-end layout, which further requires the designer should have a higher quality, can be in the PC and mobile end of the integrated design thinking. However, the

The CPU cache query tool in Linux and the cpu cache query in linux In Linux, you can use the following tool to query the CPU cache: Method 1: $ Lscpu L1d cache: 32 K Method 2: $ cat /sys/devices/system/cpu/cpu0/cache/index0/size32K $ cat /sys/devices/system/cpu/cpu0/cac

Remove the installation of memory, graphics, etc. are not difficult, but remove the CPU on the motherboard is not easy, a little attention may damage the CPU and motherboard slots, each CPU and CPU fan installation is not necessarily the same, but the same. The following details the computer how to remove the

Possible factors:1. Ambient temperatureThe cpu temperature has a lot to do with the ambient temperature. It will be a little higher in summer. Generally, the temperature is less than 50 ° when the CPU is idle, less than 65 ° when the CPU is busy, and less than 75 ° when the CPU is working at full speed. In

Http://bbs.xiyuit.com/thread-4143-1-1.htmlplease stay tuned for matching the CPU bandwidth and memory bandwidth! Don't let the memory slow down the CPU. Intel's CPU has certain requirements on memory bandwidth since P4. Why did Intel have to push Rambus to match P4? This is because both SDRAM and ddr ram are insufficient to meet P4's needs. For details, FSB is P
