Outline • The need for networking • Key elements of telecommunications and networking • The telecommunications industry • Online Advertising Spending/Growth • Case: Google
THE NEED FOR NETWORKING • Sharing of technology resources • Sharing of data • Distributed data processing and client/server systems • Enhanced communications • Marketing outreach
AN OVERVIEW OF TELECOMMUNICATIONS AND NETWORKING Networking – the electronic linking of geographically dispersed devices Telecommunications – communications (voice and data) at a distance
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING • Analog network uses continuous voltage varying as a function of time • Example: voice over telephone lines • Digital network directly transmits two discrete states • Note: 0 for pulse off and 1 for pulse on Analog and Digital Signals
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING Transmission Media Typical Speeds
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING • Computer Telecommunications Networks • Private branch exchange (PBX) Networks • Local Area Networks (LANs) • Backbone Networks • Wide Area Networks (WANs) • Internet • Internet2 Types of Networks
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING • 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 wiring Types of Networks Local Area Networks
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING • 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 (NIC) • Wireless Access Point (WAP) – radio transceiver that acts as a hub
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING 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
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING Backbone network terminology: • Bridge – connects two LANs using same protocol • 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 Backbone Network
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING • Communicate voice and data across greater distances • Usually owned by several organizations (including user organization and common carrier) • Employ point-to-point transmission • Often rely on public telephone network Types of Networks Wide Area Network (WAN)
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING • 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 Types of Networks The Internet
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING • 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 DSL, Cable Modem, and Satellite Internet Access Services
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING Intranets • Intranet– • a network operating within an organization that uses the TCP/IP protocol
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING Network Protocols • Protocol– • agreed-upon set of rules governing communication among layers or levels of a network
KEY ELEMENTS OFTELECOMMUNICATIONS ANDNETWORKING • 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 Network Protocols
THE EXPLODING ROLE OF TELECOMMUNICATIONS AND NETWORKING • Online Operations • Connectivity • Electronic Data Interchange (EDI) and Electronic Commerce • Marketing
THE TELECOMMUNICATIONS INDUSTRY • Carriers • Own or lease the physical plant – cabling, satellites, cellular towers, etc. • Sell service of transmitting communication from one location to another
THE TELECOMMUNICATIONS INDUSTRY • Equipment vendors • Manufacture and sell LAN software and hardware • Includes routers, hubs, wireless access points, digital switches, multiplexers, cellular telephones, modems
THE TELECOMMUNICATIONS INDUSTRY • 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
