The bit is physically a transistor or capacitor in a memory cell, a magnetic domain on disk or tape, a reflective spot on optical media or a high or low voltage pulsing through a circuit.
Disk caching can dramatically improve the performance of applications, because accessing a byte of data in RAM can be thousands of times faster than accessing a byte on a hard disk.
Disks and tapes can become corrupted due to hardware failure, bad software and viruses, as well as from power failures that occur while the magnetic media is being written.

 Scattered disc - Wikipedia, the free encyclopedia
The scattered disc (or scattered disk) is a distant region of our solar system, thinly populated by icy planetoids known as scattered disk objects (SDOs), a subset of the broader family of trans-Neptunian objects (TNOs).
The scattered disk is still fairly poorly understood, although prevailing astronomical opinion suggests it was formed when Kuiper belt objects (KBOs) were "scattered" by gravitational interactions with the outer planets, principally Neptune, into highly-eccentric and -inclined orbits.
The first SDO to be discovered was (15874) 1996 TL, first identified in 1996 by astronomers based at Mauna Kea.

The scattered disk is still fairly poorly understood, although prevailing astrological opinion suggests it was formed when Kuiper belt objects (KBOs) were "scattered" by gravitational interactions with the outer planets, principly Neptune, into highly-eccentric and -inclined orbits.
Inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit and is the angular distance of the orbital plane from the plane of the reference (usually planets equator or the ecliptic), stated in degrees.

 Disk - Wikipedia, the free encyclopedia
A disk or disc (see below) is anything that resembles a flattened cylinder in shape.
Disc came into the English language in the mid-17th century, from the Latin discus, and like already-existing words like whisc or risc, it was spelled with c; disk arose some time later, and was based on the original Greek root diskus.
In the 19th century, disk became the conventional spelling for audio recordings made on a flat plate, such as the gramophone record; this usage gave rise to the modern term disk jockey.

Classical objects seem to be composed of two different color populations: so called cold (inclination <5°) displaying only red colors and hot (higher inclination) population displaying the whole range of colors from blue to very red.
The intensity of light illuminating the object is known (from its distance to the Sun), and one assumes that most of its surface is in thermal equilibrium (usually not a bad assumption for an airless body).

 Scattered KB Objects
The archetypal "Scattered Kuiper Belt Object" is 1996 TL66, discovered as part of a 50 square degree survey using the University of Hawaii 2.2-m telescope on Mauna Kea.
Objects scattered to the few 100 AU aphelion distances seen in the SKBOs are immune to galactic and stellar tides, and so remain in a tightly bound swarm (the fat doughnut) surrounding the solar system.
In part because the SKBO population is very uncertain, the ratio of short-period comets delivered from the resonances to those from the scattered disk is highly uncertain.

A trans-Neptunian object (TNO) is any object in the solar system with all or most of its orbit beyond that of Neptune.
Due to the changes in the orbits of the known planets in the early 1900s, it was assumed that there was one or more planets beyond Neptune, but not yet identified.

 [17.04] Photo-polarimetric observations of Kuiper Belt Object (29981) 1999~TD$_{10}$   (Site not responding. Last check: 2007-10-17)
Knowing the surface properties of Kuiper Belt Objects is mandatory to assess the physical processes that shaped their evolution.
We present new polarization and brightness observations, obtained on the Scattered Disk Object 1999~TD with FORS1 at the ESO 8.2-m VLT.
A wavelength dependence of the polarization is observed for the first time on a KBO, with a polarization more negative in R than in V. Such a result provides constraints on the physical properties of the surface, which could be derived through elaborated numerical and laboratory simulations.

 EVIDENCE FOR AN EXTENDED SCATTERED DISK   (Site not responding. Last check: 2007-10-17)
By telescopic tracking, we have established that the trans-neptunian object (TNO) 2000 CR105 has a semimajor axis of 220+/-1 AU and perihelion distance of 44.14+/-0.02 AU, beyond the domain which has heretofore been associated with teh `scattered disk' of Kuiper Belt objects interacting via gravitational encounters with Neptune.
These objects, and two other recent discoveries which appear to have perihelia outside 40 AU, have probably been placed on these orbits by a gravitational interaction which is not strong gravitational scattering off of any of the giant planets on their current orbits.
The total population is difficult to estimate due to the ease with which such objects would have been lost without frequent tracking obersvations, illustrating the great value of rapid and well time-sampled recovery observations of trans-neptunian objects within their discovery opposition.

 2004 XR190: Enigmatic Discovery Beyond Neptune
The object, which received the official designation 2004 XR 190 in the International Astronomical Union's official announcement, was discovered during routine operation of the Canada-France Ecliptic Plane Survey (CFEPS) running as part of the Legacy Survey on the Canada France Hawaii Telescope.
Astronomer Lynne Jones of the University of British Columbia was the first to lay eyes on the new object, as she completed the initial identification in the course of processing CFEPS data from December 2004.
Due to their large eccentricities, these objects are likely to have been strongly perturbed by something, although it could not have been Neptune because they do not come close enough to be scattered by that planet's gravitational force.

 [12.01] Pinning Down the Orbits of Transneptunian Objects   (Site not responding. Last check: 2007-10-17)
The appreciation that there are a large number of sizable objects in the outer solar system is arguably the most important solar-system discovery from groundbased observations during the twentieth century.
However, most of these objects are at transneptunian distances and very faint, and the difficulty of obtaining the necessary time for follow-up observations on professional telescopes has made it necessary to involve amateur astronomers in this work, if there is to be much hope of learning anything about the objects discovered.
Professional observations of this 22nd-magnitude object at its discovery opposition were confined to two consecutive nights, and the motion was consistent with cubewano status.

 New Planet Discovered in the Solar System?   (Site not responding. Last check: 2007-10-17)
The news came hot on the heels of the announcement of the discovery of a separate planet-like object at the edge of the solar system (see "New Pluto-Size Object Discovered in Solar System")—and amid fears that a rogue astronomer may been attempting to announce the UB313 discovery as his or her own.
UB313 is being called a scattered disk object or an extreme member of the Kuiper belt.
Brown and his colleagues are uncertain of the exact size of the object, but its brightness and distance from the sun tell them that it is at least slightly larger than Pluto.

 Frankenstein and the scattered disk objects
As we know, the centaurs are thought to be scattered disk objects that have been "captured" and have entered the region of the higher planets.
Their unique orbits connect them with the farthest, really unfanthomable depths and distances that no other regular solar system object has ever been even conceived to reach until just 4 years ago, when the first of them was found to the surprise of astronomers.

 2002 RP120   (Site not responding. Last check: 2007-10-17)
Perihelion was reached in early October 2002, but as the geocentric distance was decreasing through perihelion the object reached maximum late in the month.
The aphelion distance of 2002 RP120 is approximately 108AU, well into what is termed the "scattered disk" although this is evidently not a classical scattered disk object as its orbit is almost perpendicular to the ecliptic plane.
The light curve of 2002 RP120 shows a large amount of scatter, but it appears that it can be fitted with a traditional asteroidal light curve.
