Data Communication
What is this course
Discover how physical signals turn into reliable digital information across communication media. Master signal encoding, multiplexing, channel capacity, error detection, and link-layer flow control protocols.
Who it is for
- Students studying telecommunications, electrical engineering, or networking
- Network administrators wishing to master the physical and data link layers
- Anyone curious about how bits travel through cables, radio waves, and optical fiber
Modules
- Communication models, signals, and transmission impairments
- Transmission media: twisted pair, coaxial, optical fiber, and wireless
- Digital transmission: line coding, modulation, and bandwidth
- Analog transmission and digital-to-analog conversion
- Multiplexing techniques: FDM, TDM, and WDM
- Error detection and correction: Parity, CRC, and Hamming code
- Data link control: Framing, stop-and-wait, and sliding window flow control
