Search Engine | Until the search engine appeared, computers were interconnected simply to enable people to move files to each other. Many who had a server set up to exchange files, and anyone who needed the files would come and get them. Such servers clumped together in time, and getting loads of files at one location made it easier to find them. But files were scattered across the Internet, even with the clumping. If you didn't know the location of a file, tracking it down was very difficult.
This was the question facing Alan Emtage (before 1964) who was studying at Montreal's McGill University. With restricted tech resources, it was the task of Emtage to find free internet applications for the university to use. At first, he searched by hand, creating a software database that he had discovered, but finally, being an informatics scientist, he created a program to do the job.
The first search engine was birthed in 1990. To accomplish this, Emtage's software was designed but the UNIX world standard for software names wanted them to be short and cryptic, so he removed the "v" in the "archive" and called the program "Archie." The program was a long way from current search engines, but if you knew the name of the file you were searching for it might help you find it, which was a massive leap forward.
Archie searched for file names but developed Gopher in 199, which was able to search for the text found inside files. Then search engines started using statistics to help the hunt. Yahoo added page details, and Lycos measured the closeness of terms and showed you a place pertinent to them. By 1995, AltaVista had emerged, moreover able to search for images, songs, and videos.
I hope this article based on the Search Engine was very helpful to you.
