e. In information theory, the noisy-channel coding theorem (sometimes Shannon's theorem or Shannon's limit), establishes that for any given degree of noise contamination of a communication channel, it is possible (in theory) to communicate discrete data (digital information) nearly error-free up to a computable maximum rate through the channel.
Internet background noise. Internet background noise (IBN, also known as Internet background radiation, by analogy with natural background radiation) consists of data packets on the Internet which are addressed to IP addresses or ports where there is no network device set up to receive them. Network telescopes observe the Internet background ...
Noise (signal processing) In signal processing, noise is a general term for unwanted (and, in general, unknown) modifications that a signal may suffer during capture, storage, transmission, processing, or conversion. [1] Sometimes the word is also used to mean signals that are random (unpredictable) and carry no useful information; even if they ...
The University of Illinois Department of Computer Science is the academic department encompassing the discipline of computer science at the University of Illinois Urbana-Champaign. According to U.S. News & World Report, both its undergraduate and graduate programs rank in the top five among American universities, [ 5 ][ 6 ] and according to ...
PLATO (Programmed Logic for Automatic Teaching Operations), [1][2] also known as Project Plato[3] and Project PLATO, was the first generalized computer-assisted instruction system. Starting in 1960, it ran on the University of Illinois 's ILLIAC I computer. By the late 1970s, it supported several thousand graphics terminals distributed ...

The University Library at the University of Illinois Urbana-Champaign comprises a network of physical and digital libraries. It provides resources and services to the university's students, faculty, staff, and the broader academic ...
In electronics, noise is an unwanted disturbance in an electrical signal. [1]: 5. Noise generated by electronic devices varies greatly as it is produced by several different effects. In particular, noise is inherent in physics and central to thermodynamics. Any conductor with electrical resistance will generate thermal noise inherently.
