(religion, spiritualism, and occult)

The orbits of most of the planets in the solar system lie in approximately the same geometric plane, which is why an astrological chart using only a two-dimensional representation rather than one with three dimensions is drawn. There is, nevertheless, a variation in the tilt or angle of these orbits, so at any given time most of the planets are either north or south of the celestial equator (the plane described by projecting Earth’s equator against the background of the stars). This variation is measured in degrees of declination. Two planets are parallel when they are on the same side of the celestial equator and have the same degree of declination. Planets with the same declination are said to have a relationship similar to a conjunction.

(computer science)
Simultaneous transmission of, storage of, or logical operations on the parts of a word, character, or other subdivision of a word in a computer, using separate facilities for the various parts.
Connected to the same pair of terminals. Also known as multiple; shunt.
A circle on the surface of the earth, parallel to the plane of the equator and connecting all points of equal latitude. Also known as circle of longitude; parallel of latitude.
Lines are parallel in a Euclidean space if they lie in a common plane and do not intersect.
Planes are parallel in a Euclidean three-dimensional space if they do not intersect.
A circle parallel to the primary great circle of a sphere or spheroid.
A curve is parallel to a given curve C if it consists of points that are a fixed distance from C along lines perpendicular to C.
Of two or more displacements or other vectors, having the same direction.

parallel computing

Solving a problem with multiple computers or computers made up of multiple processors. Parallel computing is an umbrella term for a variety of architectures, including symmetric multiprocessing (SMP), clusters of SMP systems, massively parallel processors (MPPs) and grid computing. See SMP, MPP, clustering, pipeline processing, vector processor, hypercube and grid computing.

Parallels Desktop

(Parallels Desktop for Mac) Virtual machine software from Parallels, Inc., Renton, WA ( that allows Windows, Linux and other operating systems to run in an Intel-based Mac. In 2006, Mac computers began shipping with Intel x86 CPU chips, enabling Windows to run natively in the machine. Parallels also supports OpenGL 3D, the graphics language used in many high-end games. See virtual machine.

Windows on the Mac Desktop
In the Mac, Windows can run full screen or in a window on the desktop. However, Parallels' "Coherence" is the smoothest mode of operation. Windows applications run in individual windows intermixed on the desktop with Mac applications. When minimized, Windows apps appear in the Mac Dock along with the Mac apps. The Windows Start menu can be set to autohide, leaving no trace of the Windows OS on the Mac desktop.

Import a Windows Machine - Switch to Mac
Parallels Desktop comes with a migration utility that can move the entire contents of a Windows PC to a Parallels virtual machine in the Mac. It can also convert virtual machines from VMware and Microsoft to a Parallels virtual machine.

The Switch to Mac Edition of Parallels includes a USB transfer cable that connects the Windows and Mac machines together for the migration. See Boot Camp, Virtual PC, VMware Fusion and Parallels Workstation.

Seamless Integration
In Coherence mode, Mac applications and Windows applications exist side-by-side on the Mac desktop, providing seamless integration of the two environments.
