The document provides an overview of the internet and its evolution. It discusses how the internet started as a US government project called ARPANET in the 1960s. It later expanded to include universities, research labs, and other networks. By the late 1980s and 1990s, the NSFNET connected supercomputer centers and commercial internet services became available, allowing the general public access to the growing network of networks called the internet. The anatomy and basic components of the internet like clients, servers, protocols, and URL addressing are also summarized.
The Internet
The internet is a network of computers linking many different types of computers all over the world.
It is a very large wide area network (WAN) connecting computers and networks around the world.
It makes it possible for millions of users to connect to one another via telephone lines, cable lines and satellites.
Basics about Internet ...
The Internet connects billions of computer users around the world through telephone and cable systems. It originated from the ARPANET network developed by the U.S. Department of Defense in the 1960s using packet switching to connect multiple computers. The TCP/IP protocol established in 1983 allowed different computer networks to communicate, creating the Internet. Routers route data packets from source to destination computers using protocols like TCP and IP.

This presentation talks about invention on Internet. How it has really changed the way people connect themselves.
InterneT
The Internet began as an experiment by the U.S. Department of Defense in the 1960s called ARPANET to create a network that would continue functioning even if parts failed. It later connected academic and research institutions and led to today's global Internet. The World Wide Web was developed in 1990 at CERN by Tim Berners-Lee and is now managed by the World Wide Web Consortium to promote open web standards. IP addresses identify devices on the Internet, with IPv4 being the current standard but running out of available addresses, leading to the development of IPv6 with a vastly larger number of possible addresses.

Computer lesson 7 files & folders
Files and folders are used to organize data on a computer. A file is a collection of data that is stored together and can be given a name, type, and location. Files are organized into folders, also called directories, to further group them together. The location and name of a file, including the file type extension, allows the computer to identify and retrieve the correct file when needed. Maintaining an organized folder structure with descriptive file names is important for efficiently finding and working with files on a computer.

Computer networking Dr. Jayarama Reddy
Networks are collections of computers, software, and hardware that are all connected to help their users work together.
A network enables users to share files and resources, such as printers, as well as send messages electronically (e-mail) to each other.
Computer networks fall into two main types: client/server networks and peer-to-peer networks.

Operating System Used by Users in day-to-day life.pptx
Dive into the realm of operating systems (OS) with Pravash Chandra Das, a seasoned Digital Forensic Analyst, as your guide. 🚀 This comprehensive presentation illuminates the core concepts, types, and evolution of OS, essential for understanding modern computing landscapes.
Beginning with the foundational definition, Das clarifies the pivotal role of OS as system software orchestrating hardware resources, software applications, and user interactions. Through succinct descriptions, he delineates the diverse types of OS, from single-user, single-task environments like early MS-DOS iterations, to multi-user, multi-tasking systems exemplified by modern Linux distributions.
Crucial components like the kernel and shell are dissected, highlighting their indispensable functions in resource management and user interface interaction. Das elucidates how the kernel acts as the central nervous system, orchestrating process scheduling, memory allocation, and device management. Meanwhile, the shell serves as the gateway for user commands, bridging the gap between human input and machine execution. 💻
The narrative then shifts to a captivating exploration of prominent desktop OSs, Windows, macOS, and Linux. Windows, with its globally ubiquitous presence and user-friendly interface, emerges as a cornerstone in personal computing history. macOS, lauded for its sleek design and seamless integration with Apple's ecosystem, stands as a beacon of stability and creativity. Linux, an open-source marvel, offers unparalleled flexibility and security, revolutionizing the computing landscape. 🖥️
Moving to the realm of mobile devices, Das unravels the dominance of Android and iOS. Android's open-source ethos fosters a vibrant ecosystem of customization and innovation, while iOS boasts a seamless user experience and robust security infrastructure. Meanwhile, discontinued platforms like Symbian and Palm OS evoke nostalgia for their pioneering roles in the smartphone revolution.
The journey concludes with a reflection on the ever-evolving landscape of OS, underscored by the emergence of real-time operating systems (RTOS) and the persistent quest for innovation and efficiency. As technology continues to shape our world, understanding the foundations and evolution of operating systems remains paramount. Join Pravash Chandra Das on this illuminating journey through the heart of computing. 🌟
