BA 471 – Telecommunications and Networking Dr. V.T. Raja Oregon State University Spring 2007

Outline Introduction –Why care about telecom/networking? Why should non-IT business students learn basics about telecom/networking? Some basics about Telecom/Networking –Analogy with effective human communication

Why telecom/networking? Some Reasons Personal Communication Group Communication Critical Infrastructure for –Traditional Businesses today (e.g., ERP at NIKE) –E-commerce Acquisition decisions and associated budget allocations IT Security Issues and Management’s Role

Some Basic Characteristics of Effective Human Communication Sender/Receiver Messages (Words) Transmission Media Air/Printed Page Speak same language or have an Interpreter Less noisy room (or) talk loud

Some Basic Characteristics of Telecommunication Networks Source; Destination – Host Signals (Digital/Analog) –Modulation (digital to analog) –Demodulation (analog to digital) –Done by a Modem Transmission Media –Wired/Wireless Communications Protocols/Standards Amplifiers/Repeaters/Internetworking Devices

Wired Transmission Media Twisted Pair Cables –Copper –Shielded and twisted to reduce noise Coaxial Cables (Cable TV) Fiber Optic Cables –Much faster –Able to go longer distances without a repeater –Uses light not electricity –Multi-color lights vastly increases capacity –Expensive Wavelength Division Multiplexing

Wireless Transmission Infrared (as in a TV remote) Radio Signals (as in microwave transmissions) Satellites – –GEOS: Geosynchronous Earth Orbiting Satellites – stationary orbit at 22,300 miles above the Earth –LEOS: Low Earth Orbiting Satellites Closer to the Earth and reachable from mobile devices 200-1,000 miles above the Earth Not stationary, goes around the Earth in about 90 minutes LEOS are needed to cover the Earth

Communication Protocols Ethernet TCP (Transmission Control Protocol) IP (Internet Protocol) HTTP (Hyper Text Transfer Protocol) SMTP (Simple Mail Transfer Protocol)

Communication Protocols Ethernet –Media Access Control (Traffic Cop – Who has access to transmission media and when? How to handle/resolve collisions?) –Error Detection/Correction –Message Delineation (Identifying beginning and ending of packets – framing) TCP –Packetizing (Breaking messages into smaller packets and reassembling packets in the correct order) –Keeping track of packet #s

Communication Protocols IP –Addressing (DHCP and DNS) –Routing Tracert Tracert

Some Basic Characteristics of Telecommunication Networks Source; Destination – Host Signals (Digital/Analog) Transmission Media (Wired/Wireless) Communications Protocols/Standards Amplifiers/Repeaters and other Internetworking Devices (e.g., hubs, switches, routers, multiplexers)
