- 4. Definition & Naming of Linux Operating System ⚫The Linux open source operating system, or Linux OS, is a freelydistributable, cross-platform operating system based on Unix that can be installed on PCs, laptops, notebooks, mobile and tablet devices, video game consoles, servers, supercomputersand more. ⚫Itwas developed by Linus Torvalds. ⚫Linus Torvalds had wanted tocall his invention "Freax” i.e., Free, Freak + x as an allusion to Unix. In this project his partner Mr. A.L.Torvalds did not think it’s a good name, So they finallydecided named their project nameas “Linux”.
- 5. History of Linux Operating System ⚫UNIX: 1969 Thompson & Ritchie AT&T Bell Labs. ⚫Commercial Vendors: Sun, HP, IBM, SGI, DEC. ⚫GNU: 1984 Richard Stallman, FSF. Open Source: GPL.
- 6. Components of Linux System a) Kernel − Kernel is thecore partof Linux. It is responsible forall majoractivitiesof thisoperating system. b) System Library − System librariesare special functionsorprograms using which application programs or system utilities accesses Kernel's features c) System Utility − System Utilityprograms are responsible todo specialized, individual level tasks.
- 7. Basic Features of Linux a) Portable − Portability meanssoftwarecan workson differenttypes of hardware in sameway. b) Open Source − Linux sourcecode is freelyavailableand it is community based development project. c) Multiprogramming − Linux isa multiprogramming system means multipleapplicationscan run atsame time. d) Security − Linux provides user security using authentication features like password protection/ controlled access tospecific files/ encryptionof data.
- 8. Architecture of Linux Operating System
- 9. The architecture of Linux contains some layers : a) Hardware layer − Hardware consistsof all peripheral devices (RAM/ HDD/ CPU etc). b) Kernel − It is the core component of Operating System, interactsdirectlywith hardware, provides low level services to upper layercomponents. c) Shell − It takescommands from the userand executes kernel's functions. d) Utilities − Utility programs that provide the user mostof the functionalitiesof an operating systems.
- 10. About Kernel ⚫It interactswith theactual hardware in machine language. ⚫It is the monarch who has overall control of everything. ⚫ It has various functions such as file management , data transfer between file system and hardware, memory management, scheduling of various programs in the memory, interrupts issues.
- 11. User-Interface of Linux ⚫The user interface iseitheracommand line interface (CLI), a graphical user interface (GUI), or through controls are associated with hardware. ⚫CLI shells are text based user interfaces, which use text for both inputand output. ⚫On desktop systems, the most popularuser interfaces are the GUI shells. ⚫Most popularuser interfaces are based on the X Window System, often simplycalled "X".

- 13. Desktop View of Linux
- 14. Inside view of Linux
- 15. Distribution of Linux ⚫Corel Linux ⚫Debian GNU/Linux ⚫OpenLinux (Caldera) ⚫Red Hat ⚫Ubuntu ⚫TurboLinux
- 16. Hardware requirements to installing Linux ⚫ CPU ⚫ Main memory ⚫ Optical Drive ⚫ Graphiccard ⚫ Hard Drive ⚫ Sound Card
- 17. Software application for Linux ⚫OpenOffice: word processing, spreadsheets, drawing ⚫Adobe Acrobat Reader ⚫Konqueror: The KDE File Manager and Web Browser ⚫TV, Video, Radio, and Webcam
- 18. Editors of Linux ⚫There are someeditors in Linux a) Vi/Vm editor b) Gediteditor c) Nanoeditor d) GNU Emacs editor e) Kate/Kwriteeditor f) Lime Texteditor and many more.
- 19. Now Comparison of Linux with Other Operating System
- 20. Linux v/s Windows ⚫Linux is freelyavailableoronlinedownloads, for windows companies have pay for their license. ⚫Windows need up todate time to time, its updating process is slowerthan Linux. ⚫Linux supports backward compatibilityunlike to the windows. ⚫Mostof thesoftware made on thewindowsare need to be licensed but in Linux all of them are freely available.
- 21. Linux v/s IOS ⚫Hardware Requirement: IOS has restrictive hardware requirement, while Linux does not. ⚫Customizability: IOS keep restrictions in thearrangement of yourdataor displaywhereas Linux can make it simpleras you want. ⚫Security: In the terms of security both of themare highlysecured, theydid not givedirect permission to theirsystem administrator.
- 22. Commands of Linux ⚫Thereare somecommands in Linux which givedirect accessories to the files by using terminal. Someof themare: ls- (List Command) mv- (Move Command) mkdir- (Make Directories) rmdir- (Remove Directory) locate- (Locate Directory) etc..,
- 23. Why we use Linux? ⚫Costless ⚫Stable ⚫Reliable ⚫Extremely powerful ⚫Highly Secure
- 24. Merits and Demerits of Linux ⚫Itcan beeasilyaccessible to theold computers . ⚫Itcannot be made forgaming purpose. ⚫It is noteasy to understand for thosewhoare new to Linux. ⚫It is mostlyused by the programmers. ⚫It is used for both commercial and personal but for home purpose, forthis Windows is mostlypreferred.
- 25. Use of Linux in various fields It is used also used in the department of Defence, Education. It is also popular in the field of Banking or Government Sector. Android App Development Operating System for Routers/Transmittin g Devices. Game Designing
- 26. Commercial use of Linux Operating System ⚫Adoption of Linux in production environments, rather than being used only by hobbyists, its widely started in the mid-off 1990s forsupercomputing purpose. ⚫Today, Linux systemsare used throughoutcomputing, from embedded systems tosupercomputersand provide a secured place in server installationssuch as the popular LAMP application stack. ⚫Linux also achieve a greatest success in the field of mobiledevelopmentwith the Android by providing ease-access and high security feature.
- 27. Conclusion “When is it best to use Linux and when should some other operating system be preferred?” It all depends on the user. Linux is only for the programmer-based environment not for the non-programmer because it is difficult to understand.
