Tentang Google & Yahoo!

Google – Regards as Popular Search Engine

The founders of Google, the leading Internet search engine, state that their mission is to organize the world’s information. Every day, their Web site handles hundreds of millions of queries for information. In seconds, it can locate specific phrases and terms on four billion Web Pages by using more than 10,000 connected computers.

Sergey Brin and Larry Page launched Google in 1998 in a friend’s garage. The name is derived from “googol,” which is the name of the name of the number 1 followed by 100 zeros. Google began offering a suite of business application in2006 that includes Gmail, Google Calendar, Google Talk and Page Creator, along with test versions of spreadsheet and word processing software.

Yahoo! – Regards as Popular Web Portal

Yahoo!, the 1^st navigational portal to the web, began as a hobby for Jerry Yang and David Filo when they were doctoral candidates in electrical engineering at Stanford University. They started creating and organizing lists of their favorite web sites in 1994. The following year, they shared their creation, named Yahoo!., with fellow students and then released their products to the Internet community.

Yahoo! Is an acronym for Yet Another Hierarchical Officious Oracle. What makes Yahoo! Unique is that staff members build the directory by assuming the role of a typical web researcher. Yahoo! Answers became second most popular Internet reference site in 2006, handling more than 12 million visitors each month. Its attractiveness is based upon the fact that anyone can ask a question at no cost, and practically anyone can offer an answer.
