Driving the Medium Carries
• What the media carries– Digital & analog signals– The digital bits are combined into bytes– The bytes move in serial or parallel– The speed of the medium is the bandwidth like T1
• Managed by transmission protocols– Ethernet – LAN Standard– ISDN – Integrated services digital network– FDDI – Fiber distributed data interface– ATM- Asynchronous transfer mode– DSL – Digital subscriber line– CSMA/CD – Carrier-sensed multiple-access with collision detection
• Area covered– LANs- Local area network– WANs – Wide area networks– MANs – Metropolitan area networks
• Network Topologies– Ring– Star– Bus

Telecommunications & Networking: What’s Important?
•Speed
•Cost
•Reliability
•Reach – To whom
•Range of Function -- What information and business services can be shared
•Security

Perspective on all the Media Discussion
Reach- Who can I communicate with?How Fast?What is the cost of bandwidth (reach)?Is the Bandwidth reliable? Can I secure my facilities secure?
Range- What applications & data can I share? What is the cost of sharing (range) Is the information reliable?Can I secure my applications and data?
