course content levels
COURSE CONTENT LEVELS
  • We looked at data comm. from a variety of perspectives:
    • Historical, technical, application, economic, architecture
  • Learned course material on several levels:
    • Vocabulary
      • What is the definition of a term?
    • Conceptual
      • What does the definition mean?
      • What is it? What does it do? How is it done?
    • Integration
      • How are multiple concepts related or different?
    • Application
      • How are concepts used to solve a problem?
evolution of data communication
EVOLUTION OF DATA COMMUNICATION
  • Direct cabling to host
    • Parallel vs. Serial Connections
  • Point-to-Point leased line services
  • Dial up over the Public Switched Network
  • Hierarchical Networks
    • SNA & Multipoint Networks
    • Built using dedicated services
  • Data Transport Networks
    • Local Area Networks: Ethernet, Token Ring
    • Wide Area Networks: X.25, IP, Frame Relay, ATM
changes in transmission
CHANGES IN TRANSMISSION
  • Analog to Digital
    • Modulation Techniques
    • Interface Standards
  • Asynchronous to Synchronous
    • Character to Block Transmission
  • Simplex & Half-Duplex to Full Duplex
  • New Transmission Media
    • Twisted Pair
    • Coaxial Cable
    • Satellite & Microwave
    • Fiber Optics
    • Wireless
ancillary improvements
ANCILLARY IMPROVEMENTS
  • Better Character Codes
    • Morse, Baudot, ASCII, EBCDIC, UniCode
  • Improvements in Efficiency
    • Multiplexers
    • FEPs & Line Sharing Devices
    • Data Compression
    • Buffering and Flow Control
  • Data Integrity
    • Parity, Checksums, Forward Error Correction
  • Data Security
    • Encryption, Digital Signatures, Firewalls
changes in computing paradigms
CHANGES IN COMPUTING PARADIGMS
  • Batch Processing (Remote Job Entry)
  • Terminal to Host
  • Client / Server
  • Peer-to-Peer
architectures and protocols
ARCHITECTURES AND PROTOCOLS
  • OSI Model
    • Seven Layers
    • Upper Layers - application oriented
    • Lower Layers - focused on data communication
  • Other Models
    • SNA, Internet
  • Using only lower layers we create data transport networks
    • LANs - typically Data Link and Physical Layers
    • WANs - typically Network, Data Link and Physical
  • Protocol stacks help us understand the data communication process
the big picture
THE BIG PICTURE
  • A Communications Revolution
    • Migration to digital and wireless transmission
    • Increases in transmission speeds & transmission needs
  • Changes in computing paradigms
  • Convergence of voice/data
  • New transmission media & technologies
    • Wireless internet access (G3) from cell phones
    • Over 140 million cell phone users today
  • The Internet & Global Connections
  • Content / Bandwidth explosion on the horizon
