  1. Computer systems Comparing functions and features of operating systems

  2. Why do you need a computer? • Running a business with a computer can be beneficial • Choose wisely • Which hardware? Which software? • Each decision will affect the next

  3. What do you need it for? • Here are the possible uses for your computer: • Accounts • Contacts • Portfolio • Till

  4. The candidates… Windows Vista • Linux/GNU

  5. Windows • Developed by Microsoft • Closed source and non free • 89.62% of the client system market share • Different operating systems designed for different purposes: • XP / Vista – Personal Computer • Server – Serving data & Active Directory

  6. LINUX • Community Project • Open source and free • Released as a kernel for the GNU project • Less than 1% of the client system market share • Just a kernel • Gentoo – Vanilla OS • Red Hat Enterprise – Commercial LAMP server • Ubuntu – Workstation oriented

  7. Initial Differences Licenses • Windows is commercial • LINUX is community

  8. Initial Cost • Windows costs at first but have consumer rights • Linux devs have no duty to you • Windows is easier to • Linux requires a greater understanding support. • Affects Total Cost of Ownership Linux is far better in terms of TCO

  9. Hardware • Windows has a majority of market share = more drivers • Linux = less drivers Windows works better ‘out of the box ‘and has better hardware support

  10. Software • Linux and Windows run different software. • Programs define operating system choice. • What programs do you need to run? • What OS are they designed for? Windows is the leader with software

  11. Software on Windows • Windows ships with little software. • Basic operating system • Small programs with limited functionality. • Commercial software developed • More likely to find specialist software that fits needs. • Better quality • Costs money • Developer has a duty to customer

  12. Windows Products • Accounts = Sage or Excel / Access • Contacts = MS Outlook • Portfolio = PowerPoint + Adobe Photoshop • Till = Actinic

  13. Software on LINUX • Installs with additional software. • Free and open source alternative for commercial apps • Inferior Quality • No legal rights • Smaller range • Free community support • Reduce costs

  14. Linux Products • Accounts = GNU cash • Contacts = Thunderbird • Portfolio = Gimp + Magic point • Till = Vigilant

  15. Usability Windows – • GUI improves usability • Generally more accessible • GUI integrated • Troubleshooters Linux- • Ubuntu usable by the computer literate • GUI just frontend for configuration files. • Difficult to fix for a less experienced user • Linux just ‘man files’ Windows is easier requiring less training

  16. Security Windows - • Windows easier to be exploited • Popular OS • Targeted by viruses Linux – • Linux more secure • Only beneficial if networked. Linux wins this one

  17. Stability and Performance Linux – • CLI OS • More stable • Efficient • Can be run without a GUI Windows – • GUI OS • Requires more resources • Requires more powerful hardware. Linux is less power hungry and more stable

  18. Conclusion • I recommend running MS Windows on your computer because: • Usability • Compatibility • Software
