The loss of signal energy over distance. As a signal moves through a medium, the medium's resistance converts some of that electrical energy into heat. This requires the use of amplifiers or repeaters.
Uses one voltage level for binary 1 and zero voltage for binary 0.
Definitions, types of networks (LAN, MAN, WAN), and network topologies.
Omnidirectional waves used for multicast communications (AM/FM radio, cordless phones). The loss of signal energy over distance
Unwanted, external thermal or electromagnetic energy that corrupts the original signal. Types include thermal noise, induced noise, crosstalk, and impulse noise (like lightning or power spikes). 6. Transmission Media: Guided vs. Unguided

The search results had changed. The exclusive link was gone. In its place was a standard, boring PDF of the actual textbook, "Computer Networks" by a different author entirely. No strange green text. No 450MB file size. Uses one voltage level for binary 1 and
Computer Network and Data Transmission: A Comprehensive Guide to J.S. Katre's Engineering Insights
Data transmission is also defined by the direction of flow. The exclusive technical breakdown by J.S. Katre often includes this table:
: Used exclusively in fiber-optic communications; combines multiple light signals of different wavelengths (colors) onto a single optical fiber. Switching Techniques Detailed explanation of Parity checks
Beyond data transmission, the book is structured to follow the hierarchical approach of network protocols: A. Network Models & Topologies
: Unidirectional, line-of-sight high-frequency waves used for satellite communications and terrestrial point-to-point links.
Detailed explanation of Parity checks, Checksums, and Cyclic Redundancy Check (CRC).
