A computer network is a collection of interconnected devices that communicate with each other to share resources and exchange data. These devices, called nodes, can be computers, servers, printers, routers, switches, and other networking equipment. Computer networks have revolutionized the way we communicate, access information, and conduct business.
: Multiple bits are sent simultaneously over multiple wires. It is faster but limited by cost and signal skew over distance. Synchronization Asynchronous

JS Katre style
: Transmits data as light pulses through a glass or plastic core using the principle of total internal reflection. It provides exceptionally high bandwidth, experiences minimal attenuation, and is completely immune to electromagnetic interference. Unguided Media (Wireless)
Primarily written for Tech, BE, BCA, and MCA students.
Unguided media transport electromagnetic waves without using a physical conductor.
: Random or external thermal, induced, or crosstalk interference that corrupts the original signal quality. 2. Transmission Media: The Physical Layer
: Divides the link transmission time into discrete slots, allowing users to take turns transmitting data over the entire frequency spectrum (digital technique).
