Notes 1. Computer 小常识。 计算机系统的主要部件包括存储器、输入设备、处理器和输出设备。 中央处理器(CPU) 是所有计算机的核心部分。 一般的计算机的CPU主要由两部分构成: 算术/逻辑部分和控制部分。 存储器分为随机存储器(RAM) 和只读存储器(ROM)。 RAM 就是我们常说的计算机内存,是使用最多的一种存储类型...
In addition, there’s a fifth type of memory that can’t be pinned down to a specific region.Expanded memoryis actually located at addresses outside the first l024K, but your computer thinks it is inside that first megabyte. Conventional memory:the first 640K of memory addresses is where t...
