Digital Darwinism, in fact, is originated from a theory of biological evolution, called Darwinism theory, stating that all species of organisms arise and develop through the natural selection of small, inherited variations. That is a way to increase the individual’s ability to compete, survive, and reproduce. Similarly, this kind of theory can also be applied to the current digital areas in the market, weeding out decayed business models as to boost the revolution of the market.

注册清除和修复
Windows注册包括你计算机上的每一件事的总和。不幸的是，它有时也包括在你计算机里用过而没有被清除的东西。这些垃圾增大了注册的容量使其运行很慢。就像碎片硬盘一样。因此，为了使你的计算机处于最佳状态，我建议用程序清除注册。仅有几个软件可以应用，包括：注册机、注册急救、Windows注册修复SE、注册修复、混合程序。
在应用数量方面，最流行的面向对象的编程语言是C++。它用于商业开发的一大优点就在于和人们熟知并已使用的C语言句法相似，从而降低了培训费用。此外，C++支持包括类，继承，信息隐藏，多态性和动态绑定等所有面向对象概念。C++的劣势在于它多态性和动态绑定的程度未达到大多面向对象程序员的期望。Ada 95 是一个可靠的标准化语言，适用于开发大型复杂可靠的系统。
苹果计算机和PC很好共存于当今世界，硬件兼容，软件有效。
为什么要买PC？
几乎所有人都熟悉今天的PC。PC就是一台由Dell、Gateway、Compaq等公司所制造的带有微软视窗平台的计算机。微软视窗是一个标准的软件操作系统， 大量现有软件都是为这个操作系统设计的。如果你要用计算机来完成某些工作，你必然可以找到许多在微软视窗平台上工作的软件帮助你完成这个工作。PC是现在最常见计算机类型，对软硬件有极佳的兼容性。
购买苹果计算机的主要优势在于苹果计算机更易操作，出错少，也可以做PC能做的任何事情。
结束语
当你购买一台计算机时，你要知道无论是PC还是苹果计算机都有它们各自的优缺点，没有一个明显的界限来帮你做出决定。
