Shallow copy is a bit-wise copy of an object. A new object is created that has an exact copy of the values in the original object.

The deep Web is the part of the Internet that is inaccessible to conventional search engine s, and consequently, to most users. According to researcher Marcus P. Zillman of DeepWebResearch.info, as of January 2006, the deep Web contained somewhere in the vicinity of 900 billion pages of information. In contrast, Google, the largest search engine, had indexed just 25 billion pages. Deep Web content includes information in private databases that are accessible over the Internet but not intended to be crawled by search engines.
