Power-on self-test. A power-on self-test ( POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [1] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
Water memory is an example of pseudoscience and contradicts the scientific understanding of physical chemistry and is generally not accepted by the scientific community. In 1988, Jacques Benveniste and colleagues published a study supporting a water memory effect amid controversy in Nature, [1] accompanied by an editorial by Nature 's editor ...
Noise -cancelling headphones alongside a carry case. Noise-cancelling headphones are headphones which suppress unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing . Noise cancellation makes it possible to listen to audio ...
The award-winning software clears out all the junk from your computer, fixes shaky WiFi connections, and frees up lots of storage space so your device functions like (almost) new again. For just ...
Here’s how you can do the same — and not just for your car. Buy to keep. When Veitch bought her car, she knew she wanted the $3,289 vehicle to last forever. She learned all the mechanical ...
A micrograph of the corner of the photosensor array of a webcam digital camera Image sensor (upper left) on the motherboard of a Nikon Coolpix L2 6 MP. The two main types of digital image sensors are the charge-coupled device (CCD) and the active-pixel sensor (CMOS sensor), fabricated in complementary MOS (CMOS) or N-type MOS (NMOS or Live MOS) technologies.
A cyclic redundancy check ( CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. [1] [2] Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents.
Read-only memory ( ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware.
