Any program must be loaded into "memory" before it can be executed by the CPU. The memory is used to temporarily store the calculation data in the CPU. All programs in the computer are run in the memory; as long as the computer starts running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation. When the calculation is completed, The CPU transmits the results.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
Any program must be loaded into "memory" before it can be executed by the CPU.
Memory is an important component of the computer, also known as internal memory and main memory. It is used to temporarily store operation data in the CPU, as well as data exchanged with external memories such as hard disks.
Memory is the bridge between external memory and the CPU. All programs in the computer run in the memory. The performance of the memory affects the overall performance of the computer.
As long as the computer starts running, the operating system will transfer the data that needs to be calculated from the memory to the CPU for calculation. When the calculation is completed, the CPU will transmit the results.
The programs we usually use, such as: Windows operating system, typing software, game software, etc. They are generally installed on external storage such as hard disks, but their functions cannot be used only because they must be transferred into memory to run in order to truly use their functions.
Memory is where programs and data are temporarily stored. When we use WPS to process a document, when you type characters on the keyboard, it is stored in memory. When you choose to save, the data in the memory will be saved to the hard (disk) disk.
Extended knowledge:
Memory generally uses semiconductor storage units, including random access memory (RAM), read-only memory (ROM), and cache (CACHE ). Simply because RAM is the most important memory among them. (synchronous) SDRAM synchronous dynamic random access memory: SDRAM is 168 pins, which is the memory currently used by PENTIUM and above models.
SDRAM locks the CPU and RAM together through the same clock, so that the CPU and RAM can share a clock cycle and work synchronously at the same speed. The rising edge of each clock pulse begins to transmit data, speed 50% higher than EDO memory.
DDR (DOUBLE DATA RATE) RAM: An updated product of SDRAM. It allows data to be transmitted on the rising and falling edges of the clock pulse, so that the speed of SDRAM can be doubled without increasing the clock frequency.

核心数指的是CPU内核数量,表示一个CPU由多少个核心组成;cpu核心是CPU的重要组成部件,在内核频率、缓存大小等条件相同的情况下,CPU核心数量越多,CPU的整体性能越强。线程数是一种逻辑的概念,简单地说,就是模拟出的CPU核心数。CPU之所以要增加线程数,是源于多任务处理的需要;线程数越多,越有利于同时运行多个程序,因为线程数等同于在某个瞬间CPU能同时并行处理的任务数。

区别:1、单核就是CPU集成了一个运算核心,多核就是CPU集成了两个或多个运算核心;2、单核能同时运行的线程数较多核更少,不利于同时运行多个程序,而多核有利于同时运行多个程序;3、单核的执行速度较多核更慢,容易造成卡顿;4、多核的多任务处理效率比单核高;5、多核的性能比单核高,散热量、耗电量也比单核大;6、单核多用于部分要求轻薄、待机时间长、而对性能要求不高的笔记本电脑上。

cpu温度高的原因:1、散热不良;2、机器内灰尘过多也会引起死机故障;3、内存条故障;4、CPU超频;5、 硬盘故障;6、软硬件不兼容;7、驱动程序安装有误;8、应用软件的缺陷;9、病毒感染;10、启动的程序太多;11、用非法格式或参数非法打开或释放有关程序;12、误删除了系统文件;13、CMOS设置不当。

12核16线程指的是CPU中有12个内核,CPU的线程是16个,最多可以模拟16个核心;CPU的核心是运算器和控制器,多核可以增强并行处理能力,线程是进程中某个单一顺序的控制流,在单个程序中同时运行多个线程完成不同的工作,称为多线程。

cpu长期100度是会烧的;cpu的温度达到100度,短时间不会烧坏,只是会影响到CPU的运算效率,但是长时间保持100度就会出现烧坏硬件的情况;发热量由CPU的功率决定,而功率又和电压成正比,因此要控制好温度就要控制好CPU的核心电压。

能直接存取。内存储器又称内存,是外存与CPU进行沟通的桥梁,计算机中所有程序的运行都是在内存中进行。内存的作用是用于暂时存放CPU中的运算数据,以及与硬盘等外部存储器交换的数据。只要计算机运行,操作系统就会把需要运算的数据从内存调到CPU中进行运算;当运算完成后,CPU再将结果传送出来,内存的运行也决定了计算机的稳定运行。

cpu温度过高导致的影响:1、CPU有自我保护功能,CPU过高会自动开启保护系统,降低电脑运行速率,系统越来越慢,直至死机,反复重启;2、长时间高温(长时间85度以上),CPU的自我保护功能可能失效,会烧坏CPU;3、自动关机,且关机之后,温度未降低之前无法开机。

cpu封装温度指的是表面CPU温度,就是说从表面CPU层的温度,一般还有内核温度,相差的度数不大;中央处理器温度是指CPU外壳温度,核心温度就是CPU内核的温度;一般核心温度和封装温度是接近的,cpu表面温度比后面者低不少。
