来源：EETOP 前言 计算机必须有一个科学稳定的随机数来源，才能得到随机数。这个来源称为随机数生成器(Random number generators，RNG)。 第一个真随机数生成器是在1955年由Rand公司创造，Rand公司在1955年出版了一本《A Million Random Digits with 100,000 Normal Deviates》，用作随机 数表。 1999年，Intel发布了Intel810芯片组时，就配备硬件随机数生成器，原理是电阻和振荡器产生的热噪声。目前，大部分芯片都集成了硬件随机数生成器， 使用非常方便。 常见的随机数生成器有三种： 1. 真随机数生成器（TRNG） 基于电路的TRNG： 2. 伪随机数生成器（PRNG） TRNG生成的随机数是无周期性、不可预测、分布均匀，然而TRNG技术要求高，生成速度低，难以满足计算机高速计算需要。 因此为了提高数据产生率，TRNG的结果往往作为PRNG种子值，并以此生成伪随机的输出序列。 伪随机数算法： 1. 基于二进制字段上的矩阵线性递归，可以快速产生高质量的伪随机数。随机数范围[0，2*k)，k=19937，32，64。计算机 ...

本文转自【齐鲁晚报】； "报价单只管当天，明天什么价没人知道。"近日，在深圳华强北电子市场，一位电脑组装商向记者展示了最新的存储产品报价单。 该组装商表示，一款铠侠2T硬盘的价格从12月初的约1000元上涨至1500元，金百达的一款32*2内存条则从3000元上涨至4500元，涨幅均在 50%左右。 这意味着，仅因存储部件的价格变动，令这台目前总价约12500元的电脑的装机成本，在一个月间增加了25%。 至于单价本身就很高的服务器内存，涨价则更加惊人。 一款海力士的DDR5 256GB服务器内存条的京东价格在过去10天里两次上调，从38999元/条涨至45999元/条再到47999元/条，这价格直接涨出 一台iPhone。 价格剧烈波动，供应链的交易条件也随之收紧，一位国内存储模组厂市场负责人就告诉记者，公司产品1月份还将上涨10%-15%，他向客户发 出的建议是"尽早采购"。 在此情况下，多家手机、电视等消费电子厂商人士向记者确认，存储的涨价已经影响到了公司产品上架的节奏。分析人士表示，存储的涨价 会影响本年度消费电子产品的整体出货量。 内存条价格飙升 消费电子行业承压 家住深圳市福田区的李先生去年配置了一 ...
