Monitor

A computer is a display device. A computer programming utility used for examining and modifying memory-resident engine code programs. The computer programming interface for synchronising concurrent access to a set of variables in a computer program. A hardware device that events electrical events such as pulses or voltage levels in a digital computer. A speaker used on stage to allow musicians to hear each other. Also called fold back a video monitor, a television-like device used in studio, lab or analysis environments. A supervisory control system for installations such as SCADA to monitor significant system parameters. Special installations require adapted monitoring installations like transformer monitors or substation monitors. A Hall monitor, one who patrols the entry of a school. A Prefect, schoolboy or schoolgirl given individual authority in some British schools, especially public schools.

Solar wind

The solar wind is a stream of charged particles which are expelled from the upper atmosphere of the sun. It consists mostly of high-energy electrons and protons that are able to get away the sun's gravity in part because of the high temperature of the corona and the high kinetic energy particles gain through a process that is not well understood at this time.

They are directly related to the solar wind, together with geomagnetic storms that can knock out power grids on Earth, auroras and the plasma tail of a comet always pointing away from the sun. While early models of the solar wind used primarily thermal energy to accelerate the material, by the 1960s it was clear that thermal hurrying alone cannot account for the high speed solar wind. Some additional acceleration mechanism is required, but is not presently known, but most likely relates to magnetic fields in the solar atmosphere. The solar wind is answerable for the overall shape of Earth's magnetosphere, and fluctuations in its speed, density, direction, and entrained magnetic field powerfully affect Earth's local space environment.

Computation

Computation is a common term for any type of information processing that can be represent mathematically. This includes phenomenon ranging from simple calculations to human idea. In a more narrow meaning, computation is a process following a well distinct model that is understood and can be expressed in an algorithm, protocol, network topology, etc.
These hypothetical computing equipment can be viewed as idealised analog computers which operate on real numbers and are differential, whereas digital computers are partial to computable numbers and are algebraic. Depending on the model select, this may enable real computers to solve problems that are inextricable on digital computers.
