A little knowledge

摘要

It has been more than a decade since Larry Page and Sergey Brin founded Google. Since that time, the Web search engine has become the company's most widely known product, and the company itself has become a major American corporation. Google has been used by millions of people worldwide to find information relating to subjects from semiconductors to soybeans.rnGoogle indexes billions of Web pages using keywords and operators that link keywords so that users can search for information. Given a little knowledge of what one is looking for, the search engine can be a powerful tool. If you know that you need to perform an FFT on an FPGA, for example, simply typing "FPGA FFT" into the search engine will return many relevant results. Although a more formal structure such as "field programmable gate array fast Fourier transform" may be more meaningful, such an expression will not return as relevant a list of results. In such cases, a little knowledge about the subject and acronyms may be the fastest way to find the information you need.
