The World Wide Web is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and accessible via the Internet. It was invented by Tim Berners-Lee in 1989 and has since become a fundamental platform for sharing and accessing information globally.
Hypertext Markup Language (HTML) is the standard language used to create the structure and content of web pages by using a system of tags to organize text, images, links, and other elements. It serves as the backbone of the internet, allowing browsers to interpret and display web content correctly.
A Uniform Resource Locator (URL) is a unique identifier for locating resources on the internet, functioning as the address for webpages and other online assets. It typically consists of several components including the protocol, domain, path, and optional parameters and fragments, each serving a specific purpose in directing the user to the desired resource.
A web browser is a software application used to access and interact with information on the World Wide Web. It retrieves, presents, and traverses resources such as web pages, images, and videos, allowing users to navigate the internet seamlessly.
Concept
A web server is a software or hardware system that serves web pages to users over the internet or an intranet by processing requests via HTTP or HTTPS protocols. It is a crucial component of the internet infrastructure, enabling the delivery of web content and applications to end-users, often working in conjunction with databases and application servers.
Internet Protocol (IP) is a set of rules governing the format of data sent over the internet or other network. It is responsible for addressing and routing packets of data so that they can travel across networks and arrive at the correct destination.
The Domain Name System (DNS) is a hierarchical and decentralized naming system that translates human-readable domain names, like www.example.com, into machine-readable IP addresses. It functions as the internet's phonebook, enabling users to access websites using easy-to-remember names instead of numerical IP addresses.
The client-server model is a distributed application structure that partitions tasks or workloads between service providers, known as servers, and service requesters, called clients. This model allows multiple clients to access shared resources on a network, providing scalability, centralized control, and resource management.
Information retrieval is the process of obtaining relevant information from a large repository, typically using algorithms to match user queries with data. It plays a crucial role in search engines, digital libraries, and databases, focusing on efficiency, accuracy, and relevance of the results provided to the user.
Digital communication refers to the exchange of information between devices or individuals using digital signals, enabling real-time interaction and data transmission over various platforms. It has revolutionized how we connect, work, and share information, making communication faster, more efficient, and accessible on a global scale.
Web standards are a set of guidelines and specifications established by international bodies like the World Wide Web Consortium (W3C) to ensure that websites and web technologies are universally accessible and interoperable. They promote consistency and compatibility across different web browsers and devices, enabling a seamless user experience and fostering innovation in web development.
Web accessibility ensures that websites, tools, and technologies are designed and developed so that people with disabilities can use them without barriers. It encompasses a wide range of practices and guidelines aimed at making digital content perceivable, operable, understandable, and robust for all users, including those with auditory, cognitive, neurological, physical, speech, and visual impairments.
A search engine is a software system designed to carry out web searches, which means it systematically searches the internet for specific information specified by the user, and returns a list of results ranked by relevance. It uses algorithms to index data and employs techniques like crawling, indexing, and ranking to deliver the most relevant results to users' queries.
Web development involves the creation and maintenance of websites, ensuring they are functional, user-friendly, and visually appealing. It encompasses both front-end development, which deals with the user interface, and back-end development, which handles server-side logic and database interactions.
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks that aim to access, change, or destroy sensitive information, extort money, or disrupt normal business processes. It requires a multi-layered approach involving technology, processes, and people to effectively defend against evolving threats and vulnerabilities.
Concept
Hypertext is a digital information system that allows users to navigate and create links between different pieces of text, enabling non-linear access to information. It forms the foundational structure of the World Wide Web, revolutionizing how information is accessed and shared on the internet.
Concept
Hyperlinks are the foundational elements of the web, enabling the connection between different pieces of information across the internet. They allow users to navigate from one webpage to another with a simple click, facilitating an interconnected and accessible digital world.
The history of the Internet traces back to the 1960s, evolving from a government and academic project to a global network that has fundamentally transformed communication, commerce, and information sharing. Its development was marked by key technological advancements, including the creation of the World Wide Web, which made the Internet accessible to the general public.
Hyperlinking is a fundamental technique used to navigate between different documents or sections of the same document on the web, enhancing the interconnectedness of online content. This powerful feature allows users to seamlessly access related information with a simple click, thereby improving the efficiency and interactivity of digital experiences.
