Just as a spider weaves its web to capture prey, the ‘spiders’ weave a virtual web of knowledge in the vastness of the Internet.

In this article we will delve into the operation of ‘spiders’, their importance in the field of computing and how their application in various areas, such as the sector banking and web developmenthas revolutionized the way we interact with information online.

What is the function of a spider?

The main function of a ‘spider’ or ‘spider bot’ in computing is track and collect information from manner automated in the web. These programs systematically explore web pages, following links, analyzing content, and collecting relevant data for various purposes.

How does a spider work?

A ‘spider’ or ‘spider bot’ works by following an automated process that involves several stages to track and collect information in the Web. Some of the common functions of a spider include:

Using techniques of text processing and analysis of HTML structures, the spider can identify internal and external linksas well as other resources present on the page.
  • Data extraction and storage: The spider collects desired information from the web page, such as text, metadata, links url and any other relevant data. This data can be stored in a database or in a specific format for further processing.
  • Link Tracking: If links are found on the current page, the spider follows them and repeat the process of obtaining and analyzing of content for each new URL found. This allows the spider to recursively explore different pages. web, creating a map of links and expanding its reach.
  • Control of duplicates and limits: During the process, the spider must take duplicate control into account to avoid collecting the same information multiple times. It is also common to set limits to control the depth of the crawl or the maximum number of pages to visit.
  • Continuous process: Spiders can work continuously, scouring and gathering information. on a scheduled basisor they can be executed on demand for specific tasks.
