2. ↑ moteur de recherche. Un moteur de recherche est un outil essentiel qui fait partie d'un système informatique distribué. Il s'agit d'un système logiciel qui répond aux requêtes des utilisateurs en fournissant une liste d'hyperliens, de résumés et d'images. Il utilise un système d'indexation complexe, qui est continuellement mis à jour par des robots d'indexation qui exploitent les données des serveurs web. Certains contenus restent toutefois inaccessibles à ces robots. La vitesse et l'efficacité d'un moteur de recherche dépendent fortement de son système d'indexation. Les utilisateurs interagissent avec les moteurs de recherche par l'intermédiaire d'un navigateur web ou d'une application, en saisissant des requêtes et en recevant des suggestions au fur et à mesure de la saisie. Les résultats peuvent être filtrés selon des types spécifiques et le système est accessible sur différents appareils. Cet outil est important car il permet aux utilisateurs de naviguer sur le vaste web, de trouver des contenus pertinents et de récupérer efficacement des informations.
