According to J.S. Katre's text, a computer network is a set of devices—often referred to as nodes—connected by communication links. These nodes, which can include computers, printers, or servers, are capable of sending and receiving data generated by other nodes on the network.

represents the number of signal levels used to represent data. This formula proves that higher bandwidth allows for higher data rates. Shannon Capacity

The illustrations are designed to be easily reproduced in university exams. According to J

Noise is unwanted thermal, induced, or crosstalk energy that blends with the transmitted signal. Examples include: Random motion of electrons in a conductor. Crosstalk: Effect of one wire on another.

: A network is defined as a set of devices (nodes) such as computers, printers, or scanners, interconnected by communication links. represents the number of signal levels used to

A dedicated physical path is established between two nodes before communication begins (e.g., traditional public switched telephone networks).

Made of glass or plastic and transmits data in the form of light pulses. It offers extremely high bandwidth and immunity to electromagnetic interference. Unguided Media (Wireless) Noise is unwanted thermal, induced, or crosstalk energy

Understanding computer network data transmission is essential for modern technology professionals. Utilizing comprehensive study materials, like those provided in the , allows for a structured approach to learning protocols, transmission techniques, and hardware requirements. As networks evolve towards higher speeds and improved security, these fundamental concepts remain the foundation of efficient data communication.

Data travels in both directions simultaneously (e.g., modern telephone calls and internet connections). 2. Analog vs. Digital Signals
