Portable media center

A portable media center (PMC) is a handheld device that is capable of playing digital media such as music, video, and images. PMCs are typically designed to be small and lightweight so that they can be easily carried and used on the go. Some PMCs also include features such as built-in speakers and a color … Read more

Silicon photonics

Silicon photonics is the technology of manipulating photons with silicon as the material platform. It offers the potential for very high speed data transmission over extremely long distances with low power consumption. The basic principle behind silicon photonics is that the photons can be confined in a silicon structure with very little loss. This enables … Read more

UHDV (ultra high definition video)

UHDV is a designation used by the Consumer Electronics Association (CEA) to designate video display devices and content having a native resolution of 3840×2160 pixels. The term is not used to describe standard high-definition television (HDTV) which has a resolution of 1920×1080 pixels. UHDV was originally developed as a way to improve the resolution of … Read more

Tower server

A tower server is a type of server that is designed to be placed on a floor or desktop, as opposed to being mounted in a rack. They are typically smaller and more affordable than rack-mounted servers, making them a popular choice for small businesses and home offices. Tower servers typically offer more expansion and … Read more

Inverse-square law

In physics, an inverse-square law is any physical law stating that a specified physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity. The fundamental physical quantities that obey an inverse-square law are: Gravitational force: The force of gravity between two masses is inversely proportional … Read more

SOLED (stacked organic light-emitting device)

A SOLED is a stacked organic light-emitting device. It is a type of light-emitting diode (LED) that uses organic materials to produce light. The organic materials are typically small molecules or polymers that are layered on top of each other to form a stack. SOLEDs are typically made from three main layers: an anode, a … Read more

Brain-computer interface (BCI)

A brain computer interface (BCI) is a system that translates brain signals into commands that can be executed by a computer. BCIs are typically used by people with paralysis or other conditions that make it difficult or impossible to communicate with the outside world. BCIs work by measuring brain activity and translating it into commands … Read more

HDCD (High Definition Compatible Digital)

HDCD is a proprietary audio codec developed by Pacific Microsonics. It is designed to provide improved audio quality when playing back CDs encoded with the HDCD format. HDCD discs are encoded with enhanced audio information that is not audible to the human ear, but can be decoded by HDCD-compatible devices. This results in a richer, … Read more


A micro-datacenter is a small, modular datacenter designed to provide computing and storage resources in a highly efficient and scalable way. Micro-datacenters are often used in remote or distributed locations where space is limited and power is expensive. Micro-datacenters typically consist of a small number of servers, storage devices, and networking equipment that are all … Read more

Optical computer (photonic computer)

An optical computer is a computer that uses light instead of electricity to perform calculations. Optical computers are faster and more energy-efficient than traditional computers, and they can be used for a variety of applications including weather forecasting, financial analysis, and image processing. Are optical computers possible? Yes, optical computers are possible. They use light … Read more
