Read MoreHow Web Works?
The World Wide Web (also known as the "web") is a global network of interconnected documents and other resources, linked by hyperlinks and URLs. It is a platform that allows people to access and share information, communicate with one another, and conduct business online. The web is built on top of the Internet, which is a global network of computers that are connected to each other and can communicate with one another. The Internet allows computers to send and receive data, such as emails, files, and web pages, to and from one another. The web was invented in ...
Read MoreWhat is Web Architecture?
Web architecture refers to the structural framework and design principles that define how web applications are organized, implemented, and deployed. It encompasses the technologies, protocols, and components that work together to deliver web content and functionality to users across the internet. At its core, web architecture involves the strategic arrangement of client-side and server-side components, data flow patterns, and communication protocols such as HTTP/HTTPS. It determines how users interact with web applications, how data is processed and stored, and how different system components communicate with each other. Web Architecture Overview ...
Read MoreThe URL Schemes
A URL (Uniform Resource Locator) is a string of characters that specifies the location of a resource on the internet. URL schemes define the protocol used to access different types of resources, determining how browsers and applications interact with various services. URL schemes follow the format scheme:// followed by the resource location. Each scheme has specific rules and behaviors for accessing its corresponding resource type. Common URL Schemes HTTP HTTPS FTP FILE ...
Read MoreCable TV for Data Transfer
Cable television (TV) networks have evolved beyond their original purpose of transmitting television signals to become a robust infrastructure for high-speed data transfer. Cable TV networks now serve as the backbone for internet access, telephony, and various digital services through cable modem technology, which enables data transmission over the same coaxial cables used for television broadcasting. Cable modem internet service offers significant advantages over traditional telephone line connections, providing faster speeds and greater capacity. This makes cable-based internet a popular choice for residential and business users seeking reliable broadband connectivity. What is Cable TV? Cable television is ...
Read MoreStatic Web Pages
A static web page is an HTML document that displays the same content to every visitor, regardless of when or how they access it. Unlike dynamic pages, static pages contain fixed content that doesn't change based on user interactions, database queries, or server-side processing. Static web pages are created using HTML, CSS, and sometimes JavaScript for basic client-side functionality. They are stored as files on a web server and delivered directly to users' browsers without any server-side processing or database interaction. Static Web Page Architecture ...
Read MoreCable TV Networks
Cable television networks are television channels that are delivered to viewers through cable television systems, as opposed to broadcast television, satellite television, or the internet. Some examples of popular cable TV networks in the United States include ESPN, TNT, and HBO. Cable networks can also be divided into categories, such as news networks (CNN, Fox News), sports networks (ESPN, NBC Sports), movie networks (HBO, Showtime), and lifestyle networks (Food Network, HGTV). Cable networks operate by subscription where viewers pay the operator to get access to the channels. The cable television infrastructure uses coaxial cables or fiber-optic cables to deliver ...
Read MoreThe Mobile Web
The Mobile Web refers to accessing and browsing the World Wide Web using mobile devices such as smartphones and tablets. Unlike traditional desktop browsing, mobile web experiences are optimized for smaller screens, touch interfaces, and varying network conditions. Mobile web has become the dominant form of internet access, with mobile traffic accounting for over half of global web traffic. This shift has fundamentally changed how websites are designed and how users interact with online content. Mobile Web Ecosystem Mobile Browser Web Content ...
Read MoreCalculation of TCP Checksum
The TCP checksum is a 16-bit error detection mechanism used to verify the integrity of TCP segments during transmission. It ensures that data has not been corrupted or altered while traveling across the network. The checksum calculation involves creating a pseudo-header that includes parts of the IP header, the entire TCP header (with checksum field set to zero), and the TCP data. This approach provides end-to-end error detection across both network and transport layers. TCP Checksum Calculation Process 1. Pseudo-Header IP addresses + Protocol ...
Read MoreCalling Web Service Using Curl With Telnet Connection
Curl is a powerful command-line tool for transferring data using various network protocols. It was designed to work without user interaction, making it ideal for scripts and automated tasks. Curl supports numerous protocols including HTTP, HTTPS, FTP, SFTP, Telnet, and many more. With curl, you can send HTTP requests, receive responses, upload and download files, and even handle email using SMTP and IMAP protocols. It provides extensive command-line options to control request behavior, set headers, specify request methods, and handle authentication. What is Curl? Curl is available on most operating systems and comes pre-installed on Linux and ...
