Creating a New Civilization: The Politics of the Third Wave by Alvin and Heidi Toffler

 The First Wave:

The Agricultural Revolution

The Second Wave:

The Industrial Revolution

The Third Wave:

The Information Revolution

 

"... the computer, and the television, and the telephone, are merging into one ... this industry transformation will transform not just the way Bell Atlantic behaves, but the way the public behaves - the way that we work, and the way that we play, and the way that we learn ..."

 Raymond Smith, CEO and Chairman, Bell Atlantic Corporation - Speaking at National Net '94, April 7, 1994, Washington, DC

Overview of Networking

  Local Area Networks provide:

Shared Resources

Connectivity

Data and Software Security

Data and Software Backup

Access to Network Applications

  Local Area Network Topologies, Media, and Components

Ethernet (actually, IEEE 802.3)

  

  10Base2 (ThinNet)

 

10BaseT (Twisted Pair)

 

Token Ring

  

 

  Interconnecting Local Area Networks

Bridges - between similar LANs

 

  Routers - between dissimilar LANs

  

 

Gateways - between LANs with completely different protocols

  Backbone Networks - interconnect other networks

PC LANs

Workstation LANs

Mainframe LANs

Topologies:

Ethernet

Token Ring

FDDI (Fiber-Distributed Data Interface)

ATM (Asynchronous Transfer Mode)

  Serial Communications

Modems - different protocols and speeds

Terminal Servers

PPP (Point-to-Point Protocol) replaces SLIP (Serial Line Interface Protocol)

  Models of Network Architectures

OSI (Open Systems Interconnection) - developed by the ISO (International Standards Organization)

TCP/IP (Transmission Control Protocol/Internet Protocol) - developed by the Advanced Research Projects Agency (ARPA) of the Department of Defense

SNA (Systems Network Architecture) - IBM proprietary

  Networking Protocols

TCP/IP

IPX

SNA

  The Internet

Regional Networks

National/International Networks

ANSnet

MCInet

Sprint

AT&T
