In computer science, garbage in, garbage out (GIGO) is the concept that flawed, biased or poor quality ("garbage") information or input produces a result or output of similar ("garbage") quality. The adage points to the need to improve data quality in, for example, programming.

MENACE was constructed as the result of a bet with a computer science colleague who postulated that such a machine was impossible. [5] Michie undertook the task of collecting and defining each matchbox as a "fun project", later turned into a demonstration tool. [ 6 ]
The paper rises because the air follows the curve of the paper and a curved streamline will develop pressure differences perpendicular to the airflow. [444] [445] The Coriolis effect does not cause water to consistently drain from basins in a clockwise/counter-clockwise direction depending on the hemisphere. The common myth often refers to the ...
Stop-and-copy garbage collection in a Lisp architecture: [1] Memory is divided into working and free memory; new objects are allocated in the former. When it is full (depicted), garbage collection is performed: All data structures still in use are located by pointer tracing and copied into consecutive locations in free memory.
A software engine is a core component of a complex software system. The word "engine" is a metaphor of a car's engine. Thus a software engine is a complex subsystem. There is no formal guideline for what should be called an engine, but the term has become widespread in the software industry. [1] [2] [3]
The ACM Computing Research Repository uses a classification scheme that is much coarser than the ACM subject classification, and does not cover all areas of CS, but is intended to better cover active areas of research. In addition, papers in this repository are classified according to the ACM subject classification.
The top computer science award is the ACM Turing Award, generally regarded as the Nobel Prize equivalent for Computer Science. [1] Other highly regarded top computer science awards include IEEE John von Neumann Medal awarded by the IEEE Board of Directors, and the Japan Kyoto Prize for Information Science.
