  2. What? An operating system devised by Linus Torvalds, based upon Unix It comes with a choice of desktop environments Why? It's FREE! But a new PC with Linux costs the same as with Windows Applications are free! There is an equivalent Linux application for almost every Windows personal application Where? On your PC - desktop or laptop Linux

  3. We'll look at: • Logging in • Screen layout • Standard applications • Browser • Email • Office • File Manager • Entertainment – music, videos • Finding applications • Removing applications • Anti-virus software

  4. Mult – ics Un - ix Unix – a brief history • developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, Michael Lesk and Joe Ossanna, to enable them to work on the first small computers. • Until then all computers were huge and expensive; therefore they were shared by many users. • A good operating system was: Multics • At first Unix was given to universities, including its source code. This made it very popular with a generation of software engineers. Then Bell Labs started to charge for it! • So: Linux was born

  5. You name it – Linux runs on it! • Supported platforms • Alpha, ARM, AVR32, Blackfin, C6x, ETRAX CRIS, FR-V, H8/300, Hexagon, Itanium, M32R, m68k, Microblaze, MIPS, MN103, OpenRISC, PA-RISC, PowerPC, s390, S+core, SuperH, SPARC, TILE64, Unicore32, x86, Xtensa IBM mainframe Your PC

  6. So much to choose from! • Some popular mainstream Linux distributions include Debian (and its derivatives such as Ubuntu), Fedora and openSUSE • Ubuntu - the Southern African philosophy of ubuntu ("humanity towards others") • Other well-known Linux distributions include: • Arch Linux, Knoppix, BackTrack, Kubuntu (the KDE version of Ubuntu), Linux Mint, Xubuntu • Fedora, a community distribution by Red Hat; Red Hat Enterprise Linux, maintained and commercially supported by Red Hat. • CentOS, Oracle Enterprise Linux, Mandriva, PCLinuxOS, Gentoo, Slackware, SUSE Linux Enterprise,

  7. Now we'll look at: • Another desktop – KDE • “KDE” is a play on “Common Desktop Environment” • Using the command line • Running Windows applications • e.g. MS Money • Installing Linux – on a PC already running Windows • Download the .ISO file from http://www.ubuntu.com/download/desktop • Burn onto DVD (695Mb)
