Networks and Telecommunications Strategies Dr. Robert Chi Chair and Professor, IS department Chief editor, Journal of Electronic Commerce Research

Why do computers communicate? Share –Hardware (printers, storage (SAN), CPU time (Grid Computing)) –Software (Application Software Provider) –Data (Voice, Video, text, pictures, Enterprise Database Management systems) –Information ( , Chat rooms, Newsgroup, Scheduling, project management, GDSS) To –Work collaborately –Work effectively

Components of a network Computers –Servers Development strategy –Development, Stating, Production Hosting strategy Scalability –Clients PC Think client –3 tier Client server architecture

How do computers communicate? Signals –Digital –Analog Channels –Wired Twisted Pair Wire (digital) Coaxial Cable (digital) Fiber optics (analog) –Wireless Radio, microwave and Infrared (analog)

What determines the speed Electricity travels at the same speed in different media Bandwidth –The difference of the highest and lowest frequencies of a transmission media Larger bandwidth creates more channels Examples: base band vs. broad band

Types of networks By Scale –Local Area Networks –Wide Area networks By Structure –Shared networks (Bus, ethernet) –Switched networks (Star) –Enterprise networks (hybrid)

Components of networks Modem Router Switch Gateway Bridge Hub

Transmission Digital transmission –Digital or analog signals –Repeaters Analog transmission –Analog signals only –Amplifiers

TCP/IP reference model Physical (voltage, type of wire..) IP (internet protocol) –Where data are going to TCP (transport control protocol) –How data are organized Application

Packet switch vs. circuit switch Packet Switch –Use packets –No busy lines –Many alternative routes Circuit Switch

Cell phone technologies 1G –Analog transmission 2G –Digital Transmission –20 Kbps 3G –Digital Transmission –2 mbps

The trend Integration –browser, cell, camera, TV, scanners.. Intelligent –Intelligent agent, Interactivity

Exercise 1-2 students in a group Discuss and design a network for your company –What is the current network configuration in your company –What could be the future network configuration in your company in 10 years
