1.硬盘有一个带有磁介质的硬浅盘,这与磁带和软盘中的软塑料胶片不同。
2.硬盘与盒式录音带没有什么大的差别。
两者都使用同样的磁记录技术。
3.硬盘上的信息被储存在极小的磁畴内。
而这些磁畴之所以能这么小是因为浅盘的精确度以及介质的速度。
4.RAM被视为“随机存取”,是因为你如果知道相较于某存储单元的行与列,那你就可以直接访问任何单元。
5.动态随机存取存储器存储单元中的电容器就像一个漏水的桶。
它需要定期刷新,否则就会放电至零。

1.主板就像一块底板,为系统其他部件间的通信提供电力连接,但又和底板不同,主板上还装有中央处理器以及其他子系统和设备。
2.主板的一个重要构件是微处理器的支持性芯片集,它为中央处理器和各种总线及外部元件间提供了支持性接口。
3.几乎所有的主板都包括逻辑和连接器来支持常用的输入设备,例如鼠标和键盘的PS/2接口。
4.插槽是中央处理器与主板相连接的地方。
插槽之间互不兼容,这就意味着插槽要与某种特定类型的中央处理器相匹配。
