The speed (measured in bits per second) at which data moves, influenced by frequency bands and modulation techniques. 3. Key Transmission Modes
Data travels in one direction only. A television broadcast or a traditional computer keyboard are classic examples.
Distortion happens when the signal changes its shape or form. This is common in composite signals made of different frequencies. Because different frequencies travel at different speeds through a physical medium, they arrive at the destination at slightly different times, blurring the composite wave.

This paper focuses on the and Data Transmission —core topics highlighted in Katre's curriculum-aligned chapters.
JS Katre's approach often bridges the gap between theoretical networking principles and practical, "data transmission new" applications. A "Computer Network PDF by JS Katre" typically focuses on:
High-frequency waves used for short-range communication. They cannot penetrate walls, which prevents interference between adjacent rooms. Common in remote controls and short-range wireless peripherals. 5. Digital Modulation and Multiplexing A television broadcast or a traditional computer keyboard
Smallest type, covering a personal workspace (e.g., Bluetooth devices).
This layer handles the actual mechanical and electrical specifications of the transmission medium.
Data transmission relies on physical signals moving across guided or unguided media. covering a personal workspace (e.g.
A single communication channel is shared by all machines on the network.
