Linux is an open-source operating system that originated as a personal project by Linus Torvalds in 1991. It can run on a variety of devices from servers and desktop computers to smartphones. Some key advantages of Linux include low cost, high performance, strong security, and versatility in being able to run on many system types. Popular Linux distributions include Red Hat Enterprise Linux, Debian, Ubuntu, and Mint. The document provides an overview of the history and development of Linux as well as common myths and facts about the operating system.
The document defines open source software and provides examples. Open source refers to software whose source code is publicly available and can be modified and shared by anyone. Key advantages are the availability of source code, quality from community involvement, and lower costs compared to proprietary software. Popular open source applications, operating systems, and programming languages are listed as examples, including Android, Linux, PHP, and Python. The document also discusses open source development and licensing models.
An introduction to open source softwareSanjuktaBanik
Open-source software (OSS) is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose.
This document provides an overview of the Android operating system, including its history, architecture, versions, features, advantages, and disadvantages. Android was founded in 2003 and was later acquired by Google in 2005. It uses an open source Linux kernel and is developed by the Open Handset Alliance. The architecture consists of four layers - the Linux kernel, native libraries, the Android runtime (Dalvik virtual machine), and applications. Key features include multi-tasking, a rich application ecosystem, and integration with Google services. Advantages are customization and openness, while disadvantages include inconsistent designs between apps and battery drain issues on some devices.
Proprietary software refers to commercial software where the source code is closed, and users must purchase a license to use it. Open source software is free to use and modify as the source code is publicly available. Some key differences are that open source software can be modified by users and distributed freely, while proprietary software must be purchased from the vendor and the source code is not accessible to users. Examples of each type of software were provided.
Unix is a multi-user, multi-tasking operating system that was first created in 1969 at Bell Labs. It allows many users to use the system simultaneously running multiple programs. Linux originated in 1991 as a personal project and is now a free, open source Unix-like operating system. It features multi-tasking, virtual memory, networking and more. Linux is widely used for servers, workstations, internet services and more due to its low cost, stability, and reliability compared to other operating systems.
The document discusses Linux file systems. It describes that Linux uses a hierarchical tree structure with everything treated as a file. It explains the basic components of a file system including the boot block, super block, inode list, and block list. It then covers different types of file systems for Linux like ext2, ext3, ext4, FAT32, NTFS, and network file systems like NFS and SMB. It also discusses absolute vs relative paths and mounting and unmounting filesystems using the mount and umount commands.
This document provides an overview of open source software and its adoption in education. It discusses the history and key people involved in open source software development like Richard Stallman and Linus Torvalds. The document argues that open source software provides benefits to education like cost savings, collaboration, and allowing older hardware to run new software. It recommends that schools adopt open source software for academic and financial reasons.
This ppt discusses the history of both the operating systems & compares both of them in terms of Kernel, memory management, GUI and application support.
The document discusses the history and evolution of various mobile operating systems from 1973 to present. It summarizes the key mobile operating systems including Android, iOS, Windows Phone, Blackberry OS, Firefox OS and their major versions. It also covers intelligent personal assistants like Google Now for Android, Siri for iOS and Microsoft Cortana.
Linux is the best-known and most-used open source operating system. As an operating system, Linux is software that sits underneath all of the other software on a computer, receiving requests from those programs and relaying these requests to the computer's hardware.
Open source software refers to computer software with source code that is available and may be redistributed and modified. While open source software is often free to use, the term "free" in the open source context refers to freedom rather than cost. Open source is different from solely free software in that open source software is free to use, modify, and redistribute. The open source philosophy promotes sharing of information and access to software designs and code.
Free Your Mind and Your Data Will Follow: Open Source for LibrariesNicole C. Engard
This document summarizes an presentation about open source software for libraries. It discusses what open source is, how it benefits libraries, and examples of open source products that libraries can use. Open source is defined as software where users have the freedom to use, distribute, study, and modify the code. It draws on a global community of developers to improve software. Libraries are a natural fit for open source as they value open access to information and collaboration. Common open source software used in libraries includes integrated library systems, digital archives, and discovery tools.
This document provides an overview of open source/free software by summarizing its history, development, major projects, goals, and impacts. It traces the origins of the open source movement back to the 1990s and discusses how government funding played a role in many open source projects. Examples are given of popular programming languages like Python and projects like Linux and Firefox. The goals of the free software movement are outlined as promoting certain user freedoms and accessibility of software. Both pros and cons of open source models are acknowledged. Overall the open source movement has helped increase collaboration and awareness of alternative approaches to traditional software development.

Assalamu Alaikum………
As everyone knows, with the trend of technology era 4.0, technology develops rapidly, leading to a series of languages being used more. The question that anyone who wants to learn programming is asking:
Which language should I learn first? Just learning a language is good? What language is the best?
Here I answer some of the above questions:
1. There is no language that is the highest level, level is in the hands of users.
2. Should learn which languages you can refer to this article.
3. If you want to be a programmer, you should learn a little more languages, it will help you more later.
4. There are many more questions but I can not list them all, what do you guys comment below for me.
Open source software (OSS) is software where the source code is openly available and can be modified and shared under an open source license. Key advantages of OSS include the ability to view and modify source code, involvement of a large development community, and more frequent security updates. OSS must meet requirements like making the source code available, allowing derivatives and redistribution, and not restricting use in other software or discriminating against people or fields of use. Popular examples of OSS include the Android and Linux operating systems, Firefox web browser, LibreOffice productivity suite, and programming languages like Python.
Richard Stallman developed the concept of free and open source software in the 1980s in response to proprietary software that forbade sharing and modification. He founded the Free Software Foundation and developed the GNU General Public License to ensure software remains freely available. Linux was developed by Linus Torvalds in 1991 and combined with software from the GNU project to create a fully functional open source operating system, now known as GNU/Linux. Open source software development involves volunteer contributions from around the world and has produced major programs and platforms like Linux, Apache, Firefox, and LAMP.
The document discusses open source software, including its history, definitions, common licenses, and popular packages. It provides facts about open source usage, outlines how Richard Stallman and Linus Torvalds helped establish open source concepts. The benefits are listed as cost savings, increased users, scalability, longevity, and innovation due to collaboration. Popular licenses mentioned are GPL, LGPL, BSD and Apache. Development tools highlighted are Linux, Android, MySQL, PHP and Python.
This document discusses how to choose a programming language. It recommends JavaScript for front-end development, JavaScript or Python for back-end, JavaScript for full-stack, and Python for analytics. It provides an overview of JavaScript and Python histories and why they are popular choices. The key things to consider when choosing a language are objective, popularity, job prospects, and longevity.
20 years of open source and... what’s next?Speck&Tech
ABSTRACT: Open source started as a marketing program for free software back in 1998. Starting as a controversial and disruptive idea, it has moved through the stages of acceptance to become the dominant idea in creating software systems. Why did it start and what was the timeline? Why did open source work so well? What's next?

Open source as a standard for the Public SectorPaolo Vecchi
The document discusses the benefits of open source software for the public sector. It notes that open source is already widely used today for applications like the internet, cloud computing, and more. However, public sector adoption of open source has been slow due to perceived complexity, lack of expertise, and procurement standards. The presentation argues that open source can reduce costs, increase innovation, avoid vendor lock-in, and promote data sharing and reuse between different public organizations. It promotes the idea of a shared "super cloud" infrastructure to improve efficiency. Overall, the document makes the case that open source should become a standard approach for the public sector.
Exploring the world of Open Source Design, looking at what designers are doing with open source tools like gimp, inkscape, and blender3d. We also look at how designers get creative with interface design using various designer friendly open source languages like CSS, PHP, JS, and more.
The document discusses open source software alternatives that libraries can use instead of proprietary software like Windows. It provides examples of open source operating systems like Ubuntu Linux, applications like OpenOffice and Firefox, and case studies of libraries that have successfully implemented open source solutions. The libraries realized benefits such as reducing maintenance costs, increasing reliability and security, and efficiently utilizing funding to add infrastructure instead of leasing software. Some challenges included ensuring compatibility with all websites and applications and providing enough support resources.

10. History of Open Source
Concept of free sharing information existed long before computers, For example:
Sharing of Cooking Recipe’s
In early 1960’s any computer academy who develop a software shared its source
code under the principle of openness & co-operation
Any source code, human-readable form of software, was generally distributed with
the software itself because
Users frequently modified the software themselves,
Resolve Compatibility issue with hardware or Operating System ,
Also to fix bugs or add new functionality.
This led to a “Free Software Movement” via
World Wide Web and later termed as
"Open Source”

11. Open Source Principles
Open source enables us to read the code
We can see how it’s made
The freedom to run the program for any purpose
The freedom to study how the program works, and adapt it to
your needs
The freedom to redistribute copies
The freedom to improve the program
