  36. 36. Linux vs. Windows <ul><li>Head to head competition </li></ul><ul><li>Used side by side as servers </li></ul><ul><li>Both handled daily workload for several small business operations </li></ul><ul><li>Linux with hardware disadvantage supported a community of users 3 times size of NT’s </li></ul>In The Commercial Arena
  37. 37. In The Commercial Arena <ul><li>System Administration – Most significant difference </li></ul><ul><li>Linux – tougher environment </li></ul><ul><li>Linux requires learning multi-user issues built into Unix-file permissions </li></ul><ul><li>NT – easier environment </li></ul><ul><li>NT requires less effort to get a starter server up and running </li></ul><ul><li>But in NT you have to solve multi-user issues for each and every subsystem </li></ul>
  38. 38. In The Commercial Arena <ul><li>NT – graphical interfaces, wizards and easy-to-grasp metaphors </li></ul><ul><li>But as server chores become more customized, NT cannot handle it </li></ul><ul><li>Linux – textual interface (with X-Window) </li></ul><ul><li>But for complex jobs, Linux gives a powerful set of tools </li></ul>
  39. 39. In The Commercial Arena <ul><li>NT – easy for non-programmer </li></ul><ul><li>Linux – programmer-based culture </li></ul>
  40. 40. Conclusion <ul><li>“When is it best to use Linux and when should some other operating system be preferred?” </li></ul><ul><li>It all depends on the user </li></ul>
