Webpack中的filechunkmodule

看了一遍Webpack文档，对里面的名词有很大的疑惑；

单入口来说：--------其他的不懂，哈哈

Code Splitting

webpack has two types of dependencies in its dependency tree: sync and async. Async dependencies act as split points and form a new chunk. After the chunk tree is optimized, a file is emitted for each chunk.
这里的new chunk是指一个新的文件么，页面请求时返回new chunk？
a file for each chunk是指什么？一个chunk一个js文件？

Loaders
webpack can only process Javascript natively, but loaders are used to transform other resources into Javascript. By doing so, every resource forms a module.
every resource forms a module.每个资源形成一个模块，这个模块时一个chunk么，是一个单独的请求么？

希望大家帮助我这只迷途的小羊……
