2. What is Telecommunications? • Telecommunications is the communication of information by electronic means, usually over some distance. A great deal of telecommunications is digital data transmission in which computers transmit data from 1 location to another.

3. What Is Telecommunications? (cont’d) • A Critical Business Resource. • An Increasing Number of Voice and Data Products and Services.

4. Computers Terminals Other input/output devices Communications channels Communications processors modems multiplexers controllers front-end processors Telecommunications software Basic Components of a Telecommunications System

5. Examples of Telecommunications • E-mail • Voice mail • Facsimile (fax) machines • Digital information systems • Teleconferencing • Videoconferencing • Dataconferencing

6. What is the significance of Telecommunications? • Telecommunications combines high speed digital networks in a worldwide scope which is accessible to the general public. Telecommunications networks utilize formal telecommunications standards to physically interwork globally.

7. Three Significant Telecommunications Examples (Trends?) • Internet -network of networks • Integrated Voice-Data Applications -examples include voice mail, call detail reporting • Groupware -Software that provides functions and services that support the collaborative activities of work groups.

15. Specific Telecommunication Challenges • Connectivity and Compatibility. • Performance (Processors, Bandwidth, Storage) • Cost. • Control. • Ease of Use.

16. Determine a Profile of TC Users • User connectivity needs vary or are consistent. • Network access is continuous or on demand. • Response time • Information volumes vary from big to insignificant. • User work is individual or shared.

17. Determine a Profile of TC Users (Cont’d) • Data Security Can Be an Issue. • The Location of Use is a Single or Multiple Locations. • Technical Skills of Users Can Range From Low to Very High.

18. Additional TC Considerations • Application Specific Networks Need To Be General Highways--As OPEN as possible • Acceleration of Technology Change is Accelerating the Frequency of Network Changes--Must be able to Adapt • Networks Change by Evolution, Not Revolution--Large Investment; Unwillingness to Change a System that Works • Is a Hot New Technology Here to Stay?--Which to Pick?

19. Additional TC Considerations (Cont'd) • Facility Wiring Continues To Be Important. • The Carrier Service Landscape is Changing--Competitive • Open Systems: Philosophy Versus Practical Business Needs • Business Needs Dictate Final Decisions.

22. Data Management • 1. Data Capture--How to Ecopy • 2. Indexing and Defining the Data--How to Organize • 3. Compression/Storage--How to Store? • 4. Access and Retrieval--How to Find Indexed Info? • 6. Transport--Capacity of Transmission Lines • 7. Data Presentation--Paper or Monitor

23. Mapping Telecommunications • Information Systems has become enterprise-wide systems analysis

24. Mapping Telecommunications • Measuring- Multi-vendor and Multi-Product Connectivity • Information System Architecture- Evolving ? • Distributed Systems, Cooperative Processing, and Client-Server • Open System and Standards

25. Multi-Vendor and Multi-Product Connectivity • Cost-Effective Network Represents Number of Challenges • Incompatible Systems- The Single Vendor Dilemma • Affordability of Integration

26. IS Architecture • A blueprint that depicts how future systems will be designed and built. The various systems components are explicitly defined so that multiple people can build systems around the same base line.

27. Information Systems Architecture Evolving? • IS becoming more like a manufacturing process • Effective enterprise is essential • System architecture a direction no an end point

28. Three System Alternatives • Distributed systems: multiple processors that share a network • Cooperative processing: applications are processed on multiple processors and this is transparent to the user. • Client-Server computing: A network shared by multiple processors involving split processing with specialized purposes.

29. Better performance Shared Data Easier to use Sense of Ownership Good Modularity (expand and contract) Applications implemented faster More cost effective Client Server Computing“The Best of Both Worlds!”

30. Are Open Systems a Pipe Dream? It would be so nice if the vendors could battle it out over CPU performance and let us worry about which hot box to buy. Mark Frutig VP of Technologies and Development First National Bank of Chicago

31. Open Systems and Standards • Open Systems- will allow various software applications to run on a wide range of computers tied into multiple communication networks. • Goals- open systems support the ability to- any user, any workstation, any application, any system, any network.

32. Open Systems Environment

33. Internet • What is it? • What do you do with it? • Who owns, runs and controls it? • How big is it? • How did it become what it is? • What will it be like in the future?

34. Internet • A Network of Networks. • Growth Driven by E-Mail • A Surprising Architecture for Its Time! • Uses Standards Because they Work. • Relatively Easy to Link to It. • Will Become Commercialized. • Does this Suggest Privatization?

35. Internet • 1969 First four nodes (UCLA, SRI, UCSB and Univ. of • Utah on ARPANET (DOD sponsor) • 1971 Fifteen nodes. • 1972 Thirty-seven nodes (all universities) • Main traffic had become E-mail! • 1973 First TCP draft as an international effort. • 1977 Started using TCP/IP to link other networks. • 1978 Finalized TCP/IP after four iterations. • 1980 TCP/IP became preferred military protocol. • 1984 National Science Foundation created NSFNet. • 1985 marked start of growth in TCP/IP products. • 1986 exponential growth of Internet began.
