Before getting deeply into the subject we will first know how Businesses are related to Internet, what .NET means to them and what exactly .NET is built upon. As per the product documentation from a Business perspective, there are three phases of the Internet. The First phase gets back to the early 1990's when Internet first came into general use and which brought a big revolution for Businesses. In the First phase of the Internet Businesses designed and launched their Website's and focused on the number of hits to know how many customers were visiting their site and interested in their products, etc. The Second phase is what we are in right now and in this phase Businesses are generating revenue through Online Transactions. We are now moving into the Third phase of the Internet where profit is the main priority. The focus here is to Businesses effectively communicate with their customers and partners who are geographically isolated, participate in Digital Economy and deliver a wide range of services. How can that be possible? The answer, with .NET

Web applications evolved from Web sites or Web systems. The first Web sites, created by Tim Berners-Lee while at CERN (the European Laboratory for Particle Physics), formed a distributed hypermedia system that enabled researchers to have access to documents and information published by fellow researchers, directly from their computers. Documents were accessed and viewed with a piece of software called a browser, a software application that runs on a client computer. With a browser, the user can request documents from other computers on the network and render those documents on the user’s display. To view a document, the user must start the browser and enter the name of the document and the name of the host computer where it can be found. The browser sends a request for the document to the host computer. The request is handled by a software application called a Web server, an application usually run as a service, or daemon, that monitors network activity on a special port, usually port 80. The browser sends a specially formatted request for a document (Web page) to the Web server through this network port. The Web server receives the request, locates the document on its local file system, and sends it back to the browser; see Figure 2-1. This Web system is a hypermedia system because the resources in the system are linked to one another. The term Web comes from looking at the system as a set of nodes with interconnecting links. From one viewpoint, it looks like a spider’s web. The links provide a means to navigate the resources of the system. Most of the links connect textual documents, but the system can be used to distribute audio, video, and custom data as well. Links make navigation to other documents easy. The user simply clicks a link in the document, and the browser interprets that as a request to load the referenced document or resource in its place.

Rules of Inference in Artificial Intelligence (AI) are logical principles that enable the derivation of new truths from existing knowledge, ensuring sound reasoning in automated systems. They help AI systems in theorem proving, automated reasoning, and decision-making by systematically deriving conclusions from a given set of premises. Effective use of these inference rules enhances the ability of AI to reason, solve problems, and make logical decisions in knowledge-based systems.

First-Order Logic (FOL) in Artificial Intelligence (AI) is a formal system used to represent and reason about knowledge. It extends propositional logic variables, predicates, and functions, allowing for more expressive statements about objects and their relationships. FOL enables AI systems to model complex real world scenarios, perform automated reasoning, and derive conclusions based on logical inference. It is widely used in knowledge representation, expert systems, and natural language processing, making it a foundational tool for building intelligent agents.

Propositional Logic in Artificial Intelligence (AI) is a formal system used to represent and reason about facts and relationships in a structured and unambiguous way. It consists of propositions, which are statements that can be either true or false, and logical connectives such as AND, OR, NOT, IMPLICATION, and BICONDITIONAL. In AI, propositional logic is used for knowledge representation, automated reasoning, and decision-making. It enables inference through rules of deduction, such as Modus Ponens and Resolution, allowing AI systems to derive new knowledge from existing facts. However, while propositional logic is useful for simple reasoning tasks, it lacks expressiveness for handling complex domains involving variables, quantifiers, or uncertainty, which are addressed by more advanced logical systems like First-Order Logic and Probabilistic Logic.

Techniques of knowledge representation in Artificial Intelligence (AI) define how information is structured and processed for reasoning and decision-making. The main techniques include logical representation, which uses formal logic to express facts and rules; semantic networks, which represent knowledge as interconnected nodes and relationships; frames, which organize knowledge into structured templates with attributes and values; and production rules, which use "if-then" statements for decision-making. Ontologies provide a hierarchical structure of concepts and their relationships, enabling AI to understand context. These techniques help AI systems efficiently store, retrieve, and apply knowledge, making them crucial for expert systems, natural language processing, and intelligent decision-making.

Knowledge representation in Artificial Intelligence (AI) refers to the methods used to encode information about the world in a format that a computer can process and reason with.

Effective knowledge representation allows AI to perform reasoning, understand natural language, and interact intelligently with humans. It is fundamental to expert systems, natural language processing, and automated decision-making, making AI systems more efficient and capable of solving complex problems.

A knowledge-based agent in Artificial Intelligence (AI) is a system that uses a structured knowledge base to make decisions, solve problems, and interact with its environment intelligently. It consists of a knowledge base, which stores facts and rules, and an inference engine that applies logical reasoning to derive conclusions.
