硬盘是计算机上运行速度最慢的部分。之所以需要更多的内存,最主要的目的是把全部所需的指令都保留在一级缓存、二级缓存和系统内存中。如果你的计算机不得不从硬盘驱动器获得指令,性能就会大幅下降。文字处理缓存小了没关系? 客户不是专门搞电脑的,听到二级缓存这一概念,如坠五里雾中。无奈只好请教销售商。销售商不知是真不懂,还是装不懂,往往言之凿凿地指教一番。先反问一句: “你买电脑做什么用?”回答说:“搞文字处理!”这种回答最多见。于是销售商 The hard disk is the slowest part of the computer. The main reason for the need for more memory is to keep all the required instructions in the L1 cache, L2 cache, and system memory. If your computer has to get instructions from a hard drive, performance will drop dramatically. It’s okay for the word processing cache to be small. The customer is not specifically engaged in computers. Hear the concept of second-level cache, such as falling in the fog. No choice but to consult the seller. The sellers do not know if they really do not understand, or do not understand the equipment, often eloquently enlighten some advice.
