  1. Network Operating Systems Week 9 COMPUTER PLATFORMS Stuart Cunningham - Computer Platforms - 2003

  2. Week 9 • Operating System • Uses • Network Operating System • Fundamentals • Architecture • Windows 2000 family • Windows 2003 • Windows NT 4 • UNIX family • Linux flavours • Apple Macintosh OS • Novell NetWare family Stuart Cunningham - Computer Platforms - 2003

  3. Week 10 NO COMPUTER PLATFORMS LECTURES OR LABS NEXT WEEK 1st - 5th DECEMBER USE THE TIME TO WORK ON YOUR ASSIGNMENTS AND DO BACKGROUND READING Stuart Cunningham - Computer Platforms - 2003

  4. Operating System • Traditionally the OS is the interface between the user and the computer • Interact and control computer hardware • No capability to connect to remote computers • Essentially ‘stand alone’ machines Stuart Cunningham - Computer Platforms - 2003

  5. Network Operating System • Provides network communication protocols • E.g.- • TCP/IP • NetBEUI / NetBIOS • AppleTalk • IPX/SPX • Provides interaction with network hardware • Network Interface Card (NIC) • Media access • Router configuration • Allows remote access to other computers • File /Application Sharing • Administration / Control • Cluster processing • etc. Stuart Cunningham - Computer Platforms - 2003

  6. Network Operating System • Hybrid NOS • Windows 3.11 • Windows 95 / 98 • Apple Mac OS 7.x • True NOS’s • UNIX • Novell Netware • Windows NT 4 • Server and Workstation • Windows 2000 • Server and Workstation • Windows XP • Mac OS X Stuart Cunningham - Computer Platforms - 2003

  7. NOS Architecture • Client / Server • Centralised file / application sharing • Centralised control / administration • One or more servers • File server • Application server • etc. • Good security • If correctly configured • Scalable • Add more servers / clients • Expensive • Server and workstation software • Select few people in charge of administration • Good or bad? Stuart Cunningham - Computer Platforms - 2003

  8. NOS Architecture • Peer-to-peer • Everybody’s equal • No priority • No central control • Software cheap • Easy to set-up • No specialist configuration • Poor security • Suits: • Small Home / Office LANs • Networks in a single room • Networks with no interconnection requirements Stuart Cunningham - Computer Platforms - 2003

  9. Windows 2000 Server • IIS 5 • Internet Information Server • A web server • VPN Server • Virtual Private Networking • Allowing remote dial-in connections • Active Directory • Central control over all shared resources and users throughout an entire network • Requirements • Intel Pentium 133 Mhz or higher • 256 megabytes (MB) of RAM • 1.0 GB hard disk space Stuart Cunningham - Computer Platforms - 2003

  10. Windows 2000 Professional • AKA - Windows 2000 Workstation • Used for P2P or Client / Server • Client for WIN2k Server • Features of Win 98 + NT4 • Support for: • 4Gb RAM • 2 Processors using SMP • Symmetric Multiprocessing • Plug ‘n’ Play • NTFS File System • Security & Sharing Stuart Cunningham - Computer Platforms - 2003

  11. UNIX • Developed by Ken Thompson & Dennis Ritchie at Bell labs / AT&T • Multi-user • More than one person suing the OS at a time • Multitasking • Each user can run more than one process • Platform independent • Runs on almost any hardware platform • Was free at first but now expensive • Especially for PC • Complex to understand • Large distribution • User control and administration • Used as multiple types of server Stuart Cunningham - Computer Platforms - 2003

  12. Linux • Developed by Linus Torvalds • Attempt to provide functionality of UNIX in a free, easier to use form • Particularly aimed at PC users • Two parts: • Kernel • The Linux operations section • The UNIX part of things • Distribution • Particular flavour of Linux • Control and admin • Users can be created an deleted by an admin (root or su) • Users are organised into groups • Open source • Free! (more or less) • Many now have a windows style interface • Easy to get to grips with • Some expertise is required to become a master • Low hardware requirements • 100 MHz CPU, 12Mb RAM, 500Mb HDD Stuart Cunningham - Computer Platforms - 2003

  13. Linux Distributions • Lots of different flavours • Usually based around one main Linux Distribution • SuSE • Red Hat • Mandrake • Vine • Caldera • Debian • LindowsOS • Morphix • Many free and open source applications being developed Stuart Cunningham - Computer Platforms - 2003

  14. Linux Interface Stuart Cunningham - Computer Platforms - 2003

  15. Linux Interface Stuart Cunningham - Computer Platforms - 2003

  16. Linux Interface Stuart Cunningham - Computer Platforms - 2003

  17. Novell NetWare • Versions 5 and 6 most common • Sharing of resources • Novell Directory Services (NDS) • NDS e-directory • Network Services • Mail servers • Print servers • Etc. • Clients & servers • Often found running alongside another OS • Such as Windows 9x, NT, 2000 • As a client piece of software on workstations Stuart Cunningham - Computer Platforms - 2003

  18. Novell NetWare Interface • Very Windows like Stuart Cunningham - Computer Platforms - 2003

  19. Mac OS X Server • Developed by Apple Computers • Based on UNIX architecture • Designed to be run on Apple Xserve computer • File / resource sharing • Open directory • Network admin • Workgroup management • Network services • Mail • Web • Etc. Stuart Cunningham - Computer Platforms - 2003

  20. Mac OS X • Developed by Apple Computers • Based on UNIX architecture • Customisable GUI • Can connect to other networks • Windows • Novell • UNIX • Network client software • SMP support Stuart Cunningham - Computer Platforms - 2003

  21. Mac OS X Interface Stuart Cunningham - Computer Platforms - 2003

  22. Features of a NOS • User must logon to the computer / server • User name • Password • Organisation of users • Rights and privelages • Sharing of data • Provision of network services • Application services • Above all, communication Stuart Cunningham - Computer Platforms - 2003

  23. Week 9 • Operating System • Uses • Network Operating System • Fundamentals • Architecture • Windows 2000 family • Windows 2003 • Windows NT • UNIX family • Linux flavours • Apple Macintosh OS • MacOS X server/client • Novell NetWare 5 & 6 Overview Stuart Cunningham - Computer Platforms - 2003
