Difference between Spider,Crawler & Robot

HI

I have found these definition

Spider - a browser like program that downloads web pages.

Crawler – a program that automatically follows all of the links on each web page.

Robots - An automated computer program that visit websites & perform predefined task.

They are guided by search engine algorithms & are able to perform different tasks instead of just one crawling task. They can combine the tasks of crawler & spider together and help in indexing and ranking of websites on any particular search engine.

Spiders, Crowlers, Robots are different words to define the automated programs which are written to do crowling through the web. The crowlers are automated so they are called Robots and they are crowling the web (internet) so they are called Spiders.
Robots do the predefined tasks which are to download we pages and follow the links on those pages.

Thank you for the exact definition. I also think that we use all of these terms to describe the same thing.

 

A crawler is a program that visits Web sites and reads their pages and other information in order to create entries for a search engine index. The major search engines on the Web all have such a program, which is also known as a "spider" or a "bot." Crawlers are typically programmed to visit sites that have been submitted by their owners as new or updated.
