推荐答案

缓存基本上是一个临时存储区域，而它的运行的应用程序 - 它可以存储之类的东西从互联网上下载的临时图像。清除它应该不是真的有很多，从用户的角度来看的效果。清除数据，但会删除任何用户数据，数据库等 - 这包括诸如帐户设置，持续preferences等清除数据的应的恢复应用程序恢复到它的状态因为当你第一次安装了它是。

The cache is basically a temporary storage area for an application while it's running -- it can store things like temporary images downloaded from the internet. Clearing it shouldn't really have much of an effect from a user perspective. Clearing the data, however, will remove any user data, databases, etc -- this includes things like account settings, persistent preferences, etc. Clearing the data should revert the application back to it's state as it was when you first installed it.

作为一个例子，假设我们有一个Twitter的应用程序。清除缓存可能会删除任何你以下个人资料图片的人，所以，当你看看你的时间表再次，他们将不得不再次检索从互联网上。清除数据将消除任何信息，包括您的登录信息，您关注谁，你是否希望新的微博得到通知，之类的东西。

As an example, assume we have a Twitter application. Clearing the cache might delete any profile images for people you're following, so when you look at your timeline again, they'll have to be retrieved from the internet again. Clearing the data would remove any information at all, including your login information, who you're following, whether or not you want to be notified of new tweets, and things like that.
