Definition
The Web refers to the vast interconnected system of documents and resources accessed via the internet, commonly known as the World Wide Web. It functions through a client-server model where web browsers request information from web servers, which then deliver content like web pages, images, and videos. Understanding the Web is crucial for IT professionals as it underpins much of modern digital communication, commerce, and information sharing. For instance, accessing a company's internal portal or browsing a public website both utilize Web technologies. This differs from the broader internet, which is the underlying network infrastructure that the Web uses to transmit data. Knowledge of Web protocols and security is frequently tested in domains like CompTIA Security+ and Network+.
