ECC (Error Correction Codes) is a method used to detect and correct errors introduced during data storage or transmission. Certain kinds of RAM chips inside a computer implement this technique to correct data errors and are known as ECC Memory. ECC Memory chips are predominantly used in servers rather than in client computers. Memory errors …
What are Alpha Particles? An alpha particle is a type of ionizing radiation that is exerted from radioactive materials. Alpha particles consist of two neutrons, two protons, and no electrons, giving it a net positive charge. This positive charge allows the alpha particles to leave their nucleus and bombard any nearby items with radiation. Alpha …
The broad definition of a transducer is a device that changes energy from one type into another. However, most transducers change between electricity and another energy type. Transducers also have other names depending on their usage such as probe, detector, pickup, sensor, gauge, and electrode. Chemical Transducers Acidity and alkalinity are measured using a pH …
