  1. Today, A Gameboy for $50, has more computing power than a Cray supercomputer of only 25 years ago. • Tom PetersCircle of Innovation

  2. IT Architecture

  3. Although there is always a need for improved technology, the critical resource is intelligent resourceful people who can relate business needs to technology.James J. O’Connor

  4. The central core of information technology involves a study of programming languages, algorithms and information structures.

  5. Describe Information in terms of: • Accuracy • Verifiability • Completeness • Relevance • Timeliness

  6. Computers • Supercomputer • Main Frame • Mini Computer • PC’s • Thin Clients • Laptops and Notebooks • Palmtops / PDA’s • Smart Cards

  7. Input Devices

  8. Output Devices

  9. Cable Media • Shielded Twisted Pair • Unshielded Twisted Pair • Coax • Fiber

  10. Wireless Media • Microwave • Satellite • GEO • MEO • LEO • GPS • Radio • Infrared • Cellular

  11. Networks • WAN • LAN • PAN • VPN

  12. LAN

  13. WAN’s • Network which incorporates extended geographical boundaries • Network which has a centralized point of data exchange • Network which joins remote networks in increase productivity • Network which extends existing resources

  14. Networking Standards –OSI Model • Layer 1: Physical Layer • Layer 2: Data Link layer • Layer 3: Network Layer • Layer 4: Transport Layer • Layer 5: Session Layer • Layer 6: Presentation Layer • Layer 7: Application Layer OSI Example Business Model

  15. Equipment • Repeaters • Bridges (DSU/CSU) • Routers • Hubs / Switches • Interface Cards (NIC)

  16. Connectivity Services • Switched • Dedicated • Packet • Modems • Frame Relay

  17. DDS Switched Phone Networks 56K T1 T3 OC3 OC12 OC192 ATM ISDN xDSL Cable Modems Connectivity Bandwidth

  18. LAN"A data communications system allowing a number of independent devices to communicate directly with each other, within a moderately sized geographic area over a physical communications channel of moderate data rates." IEEE

  19. Topology • Bus - Ethernet • Token Ring • Star

  20. Protocols • TCP/IP • IPX • Netbui • SNMP (Management protocol) • Appletalk • X.25 • Z39.50 • IPNG??

  21. Why LANs • Need to share data, software, and hardware • Centralized management • Share access to outside sources

  22. Future • To distribute expertise not just files • Remote offices have leadership and expertise - Videoconferencing • Teleworkers need to be part of the structure
