INFORMATION SYSTEM

The "bow tie" structure is a concept often used to represent the architecture and connectivity of the World Wide Web. It was introduced by researchers to describe the evolution of the web's structure and the role of different components within it. The bow tie structure consists of several interconnected components, resembling the shape of a bow tie. 

Components of Bow-Tie Structure :

Core:

Description: The central core of the bow tie represents the most connected and influential part of the web.

Characteristics: High-degree nodes, typically major websites, search engines, and hubs that have a large number of incoming and outgoing links.

Function: This core is crucial for the overall connectivity of the web, and changes in this core can significantly impact the entire structure.

In and Out Tendrils (or Wings):

Description: The in and out tendrils represent the components connected to the core, extending on either side like the wings of a bow tie.

Characteristics:

In-Tendril (Left Wing): Consists of pages that link to the core but do not receive many links in return.

Out-Tendril (Right Wing): Consists of pages that the core links to but don't receive many links from other pages.

Function: These tendrils illustrate the web's hierarchical structure, showing pages that are more focused on providing links (in-tendril) and pages that are more focused on receiving links (out-tendril).

Tubes:

Description: The tubes represent the connections between different components of the web, bypassing the core.

Characteristics: These connections allow for alternative pathways between pages, creating alternative routes for information flow.

Function: Tubes contribute to the robustness and resilience of the web by providing alternative routes in case a part of the core or tendrils is disrupted.

Disconnector:

 

Description: The disconnector is a component that separates the web into two disconnected parts.

Characteristics: A disconnector could be a set of pages or nodes that, when removed, isolates one part of the web from another.

Function: Understanding disconnectors is crucial for identifying potential vulnerabilities and points of failure in the web structure.

 

Different Parts of the Bow Tie:

Core + In-Tendril + Out-Tendril: Often referred to as the "strongly connected component" or the "main core" of the web.

Tubes: Represent alternative routes and pathways that enhance the overall connectivity.

Disconnected Components: Illustrate potential isolated regions of the web.

               The bow tie structure provides a visual representation of the web's architecture, emphasizing the core's importance and showcasing the interconnectivity and alternative pathways within the web. It's a useful model for understanding the resilience and vulnerabilities of the web, as well as for analyzing the impact of changes in its structure over time.
