Data Processing has changed greatly over time. While one can track the beginnings of the modern analytical computer to Charles Babbage (1791-1871), we really saw the beginning of modern day information systems during World War II when they were used as code busters. After the war, few anticipated how much computers would affect our lives. Early on even IBM thought that there would only be a handful of companies that would need a computer.

In those days, computers were massive systems based on vacuum tubes and core memory. With the advent of the integrated circuit, computer architectures took a giant leap forward. The mainframe systems of the late 1980's evolved into Client/Server applications of the early 1990's. In parallel, the Internet grew from a few engineer and research systems to a World Wide network. It wasn't until an Al Gore authored bill allowing commerce to be carried out over the Internet did things really start to change. Every business, every organization, h... [more]

The drum is then rolled through a toner picked up by the charged portions of the drum. Finally the toner is transferred to the paper through a combination of heat and transfer.

Laser printers are considered to be the most ideal printing tools for printing today. Initially due to their high cost they were only favorable to big business houses however off late with a fall in prices they have been accepted in both homes and office environments.

Laser printer is known for its high quality text printing and exce... [more]

So, what is a search engine and what does it do?

(and -- can I run my own search engine on my domain -- an analysis)



Search engine is a program or a tool that searches for the information on the Internet based on the words which user insert into the search box. After the words are inserted into the search box and when you click on search button the search engine looks into its own database to find out whether it contains those information which the user is actually looking for.



There are many major search engines of the web. Why are these considered to be "major" search engines? Because they are either well known or well used like Google and Yahoo. But then, there are lots of other search engines as well, for eg: DogPile is a search engine that is based on MetaSearch (a search engine pulling out results from other search engines) also among those who are "TRUE- search engines (Search engines having their own database...
