- Introduction - The role of data
communications and evolution of telecommunications and computer
networks. The fundamental issues of transmission rate, response time,
reliability, security, architecture, networking. Standards and layered
architectures: the OSI model and TCP/IP.
- Data, Signals and Information
Transmission - Binary and m-ary data. Analog and digital
signals, frequency and wavelength, Fourier analysis, bandwidth and data
rates, impairments. Encoding information. Capacity formulas: Nyquist
and Shannon. Voice, data and video signal examples.
- Transmission Media - The
characteristics of twisted pair, coaxial cable, and fiber-optic media
for signal transmission. Wireless media: microwave, satellite,
and cellular. Capacity and cost.
- Coding and Modulation -
Digital signal formats. Amplitude, frequency and phase modulation of
carrier signals; modems.
- Digital Voice and Image (Multimedia) -
The sampling theorem and analog to digital conversion. Basic PCM voice
and digital video, codecs and compression.
- Physical-Layer Interfaces -
Synchronous vs. asynchronous, and balanced vs. unbalanced transmission.
Interfacing standards: e.g., EIA-232, USB, Ethernet and Wi-Fi.
- Error Control Strategies -
Error rates. Reliable transmission over unreliable
links. Error-detection and error-correction schemes, combined
- Link Layer Protocols - Acknowledgments,
flow control and error control. Delay and sliding windows. Link-layer
protocols: HDLC, SLIP and PPP.
- Multiplexing - Sharing communication
media: time, frequency and code-division multiplexing. Statistical
multiplexing and queuing models for capacity and delay on shared links.
- Introduction To Networking -
Networking resources and strategies. LANs vs. wide area networks.
Packet vs. circuit switching. Principles of LANs and the Internet.
- Report - Students are expected to prepare
and present a paper describing an application or technology for data
