Networking –
the electronic linking of geographically dispersed devices

Telecommunications –
communications (voice and data) at a distance
Analog and Digital Signals

       Analog network uses continuous voltage varying as
        a function of time
         Example: voice over telephone lines
       Digital network directly transmits two discrete
         Note: 0 for pulse off and 1 for pulse on
Transmission Media   Typical Speeds
Types of Networks
   Computer Telecommunications Networks
   Private branch exchange (PBX) Networks
   Local Area Networks (LANs)
   Backbone Networks
   Wide Area Networks (WANs)
   Internet
   Internet2
Types of Networks
Local Area Networks
     Owned by a single organization
     Operate within area 2-3 miles in diameter
     Contain a number of intelligent devices,
      usually microcomputers, that can process data
      … based on peer-to-peer relationship
     No part of telephone system, have their own
Wireless LAN
   • Known as Wi-Fi (wireless fidelity)
   • Growing in demand for corporate and home use
   • Use IEEE 802.11 standards with shared
      Ethernet design
   • Requires use of wireless network interface card
   • Wireless Access Point (WAP) – radio transceiver
      that acts as a hub
Types of Networks
Backbone Network

In-between network that interconnects LANs in a
single organization with each other and with
organization’s WAN and the Internet
Types of Networks
Backbone Network
Backbone network terminology:
   Bridge – connects two LANs using same
   Router (gateway) – connects two or more LANs
     that may use different protocols
   Switch – connects more than two LANs using
     the same protocols
Types of Networks
Wide Area Network (WAN)

    Communicate voice and data across greater
    Usually owned by several organizations
     (including user organization and common
    Employ point-to-point transmission
    Often rely on public telephone network
    Types of Networks
    The Internet
     Network of networks that use the TCP/IP protocol
     Contain gateways to computers that do not use TCP/IP
     Provides four basic functions:
        Electronic mail
        Remote login
        Discussion groups
        Sharing of data resources
    DSL, Cable Modem, and Satellite
    Internet Access Services

     Digital subscriber line (DSL) – service offered by telephone
     companies using copper wire already installed in homes …
     moving data over wires without disturbing voice traffic
     Cable modem – connection obtained from cable TV
     company using existing home coaxial cable
     Satellite – most expensive, but may be only option for
     customers in rural areas

Intranet –
    a network operating within an organization that uses
    the TCP/IP protocol
Network Protocols
Protocol –
   agreed-upon set of rules governing communication
   among layers or levels of a network
Network Protocols
       International Organization for Standardization (ISO)
        network protocol – Open Systems Interconnection
        Reference Model (OSI)
         Thought to become the only standard for networking
         Gained momentum until Internet explosion
       Transmission Control Protocol/Internet Protocol (TCP/IP)
         Has become the de facto standard for networking today
   Online Operations
   Connectivity
   Electronic Data Interchange (EDI) and Electronic
   Marketing
       Carriers
         Own or lease the physical plant – cabling, satellites, cellular
          towers, etc.
         Sell service of transmitting communication from one location
          to another
       Equipment vendors
         Manufacture and sell LAN software and hardware
         Includes routers, hubs, wireless access points, digital
          switches, multiplexers, cellular telephones, modems
       Service providers
         Operate networks and deliver services through the network
         Provide access to or services via the Internet (such as AOL,
          Microsoft Network, Yahoo!, and many ISPs
