The process of updating and synchronizing all routing tables in a network, so that all routers agree on new metrics or topology is referred to as convergence. Large networks converge more slowly than small networks, because of the larger number of routers that must be updated after each change.

The coming together of futures prices and cash market prices on the final trading...

CONvergence is a speculative fiction convention held annually on the first weekend in July in Minnesota, United States. Sponsored by the local fan organization MISFITS, the convention began in 1999 at the Bloomington Radisson South Hotel and continues to be held every year at the same location, now known as the Sheraton Bloomington. This location has been used by local fandom for a variety of conventions, including Minicon and Mars Con. 2007's theme is to be "Creature Feature" (horror and monsters).

This is a trend related to technological devices. Some devices that originally had distinct purposes take on each other's functions and eventually become one device. For example, office communications used to take place on separate machines: one for typing a letter and another for faxing it to someone else. Today both of these functions can be managed by a desktop computer.

Used on conventional colour televisions, circuits are required to align the three scanning electron beams that produce a colour picture. Mis-aligned beams degrade the quality of the picture. This was a common problem in the early 1970's when TV's were working with both valves and transistors.

Convergence is an amorphous evolutionary term that is used in somewhat different senses by different authors (or even by the same people at different times). It generally refers to similarities between organisms that evolved independently, i.e. similarities not directly inherited from a common ancestor. Strict convergence of both function and structure is rare, except in trivial cases. Convergence of form and function is common, and is predicted by natural selection. In a sense, convergence is the opposite of homology.

Convergence denotes the coming together of diverse communications technologies so that they no longer have unique associations with particular types of service. Radio and television broadcasts can be delivered to the home by cable instead of through the ether, but that same cable can also carry voice telephony and data. Satellites can handle all types of telecommunications traffic, including broadcasting direct to the home. The personal computer, when connected to a telephone line, becomes an audio- visual receiver as well as a data terminal. The Internet has a capability for broadcasting as well as point-to-point data carriage, despite being accessed through the 'plain old telephone system'. Radiotelephony, once a specialised and highly regulated technique, is now an everyday facility in the form of cellular mobile telephones. The wired telephone systems now carry services that were unknown in the days before liberalisation, and will be able to deliver many more as digital technology is extended.

Convergence: Alignment of the red, green and blue (RGB) video images. Projectors correctly aligned produce a clear, full-colour picture.

a process of market and industry restructuring, resulting from the ability to use digital technology to transmit information (e.g. pictures, video, sound, text or data) in digital form over any transmission medium (e.g. cable, satellite, wireless networks), and receive the information on a range of devices (e.g. telephone, television, personal computer).

Alignment of the vertical and horizontal lines in an image.

The idea of different markets or industries (in telecommunications, generally) growing and eventually overlapping in offered goods or services.  For example, cable television providers have long hoped for the technology that would allow them to offer phone service and Internet access.  Phone companies hope to one day use their existing lines to offer 400+ video channels.  Thus, the two markets would converge.

process of using extraocular muscles to direct the visual axes of the two eyes to a near point (simultaneous turning of the eyes inward)

Convergence problems are fatiguing and the amount and efficiency of visual information processed is reduced.

Bringing together multiple telecommunications technologies--computers/telephone/video/etc. The united delivery of products and services previously delivered separately. (Example: Cable company providing local phone service or phone company providing video services.)

Eyes' ability to turn inward. People with convergence insufficiency have trouble (eyestrain, blurred vision, etc.) with near tasks such as reading.

The movement of the cash asset price toward the futures price as the expiration date of the futures contract approaches.

Horizontal inflow of wind into an area. Once at the area, the wind then travels vertically.

The process of stabilizing a system after changes occur in the network. For routing, if a route becomes unavailable, routers send update messages throughout the internetwork, reestablishing information about preferred routes. For Network Load Balancing, a process by which hosts exchange messages to determine a new, consistent state of the cluster and to elect the host with the highest host priority, known as the default host. During convergence, a new load distribution is determined for hosts that share the handling of network traffic for specific TCP or UDP ports. See also: cluster; default host; host; User Datagram Protocol (UDP)

The meeting of lines of sight through the eyes, or light rays through the optical system, at a common point closer than infinity.

The coming together of disparate technologies, such as internet services, television and other forms of entertainment. Nearly everyone knows how to work a television set, but PCS are much harder for them to master. It makes sense, then, for the television to act as a central source of digital information, whether it be e-mail, the web, satellite and cable television, video-on-demand or video games.

The tendency of difference between spot and futures contract to decline continuously, so as to become zero on the date of maturity.

Three colors-red, blue, and green-are used in television to produce all colors. These separate scanning beams (one for each color) must strike their targeted phosphors (screen's internal coating) with precise accuracy. If the beams are out of alignment, then the image and colors appear muddied.

As used in sales forecasting, this term means the simultaneous use of multiple forecasting techniques to arrive at a single sales estimate. The estimates emanating from the individual techniques (e.g., analogs, regression formulas, normal curves, market share, etc.) are compared by the analyst (or in automated routines in more sophisticated application systems) to determine the best final estimate based on the inherent strengths and weaknesses of each technique in the circumstances under review. In some situations, the analyst may place more emphasis/weight on the output of a model formula than analogs and in other cases they may be treated as equally applicable. Convergence forecasting has proven to be a valuable method in producing highly accurate sales forecasts. See Convergent Sales Forecasting for a more detailed explanation.

In futures trading, the point in any given month when the price of the near-month contract effectively settles at or very near the cash market price.

The process of adapting one's speech style to match that of others with whom one wants to identify. See also divergence.

the approach of an infinite series to a finite limit.

Precisely every individual in the population is identical. While full convergence might be seen in genetic algorithms using only cross over, such convergence is seldom seen in genetic programming using Koza's subtree swapping crossover. However, populations often stabilise after a time, in the sense that the best programs all have a common ancestor and their behaviour is very similar (or identical) both to each other and to that of high fitness programs from the previous (and future?) generations.

In the context of the new economy, convergence combines personal computers, telecommunication, and television into a user experience accessible to everyone. Accessing Internet via cable television or viewing e-mails on the mobile phone are simple examples of convergence.

Integration of computing and communications technologies in an all-digital environment. As more media and services increasingly become digital, the more they can be tied together or mixed. Convergence distribution is also becoming more diverse with many new ways of delivering mixed media and its use.

Adjustment of red, green and blue color on a rear projection set. The three CRTs inside a rear projection set occasionally need this adjustment to ensure a sharp picture.

The ability of the three electron beams (red, green and blue) in a CRT monitor to meet at a single point and produce one dot. If a monitor is mis-converging, you will notice shadows of blue or red around any white images. Often, this will occur in only some parts of the screen. Some monitors have convergence controls, but most do not.

The alignment of three electron beams in a CRT based television to converge on one point. When a one red, one green and one blue beam converge, they create white light. The failure of these beams to converge precisely will result in color haloing of images on screen.

Consider an area on the earth's surface. On the sides which face the wind, air will flow into the area, while on the other sides air will flow out. If, however, the wind is not uniform, more air may flow in than flows out, and the amount of air in the area will tend to increase: this process is called convergence. The air cannot, however, go on accumulating and excess will have to flow out over the top, thus leading to a rising air current, and perhaps to clouds and rain. The contrary case is called divergence.

Color CRTs rely on three separate electrical beams to project simultaneous red, green, and blue images; these combine to form a full-color image. If these beams are not precisely aligned, the red, green, and blue portions of the image may not overlap correctly, degrading the overall image quality. When the three beams converge correctly at all points on the display, you get a perfect image.

The combining of information technologies that were previously considered distinct and separate (e.g., telephones and television) but are now beginning to overlap and converge on each other.

The consolidation of all communications - voice, data (Internet, ATM, Frame Relay, etc), and video (broadcast TV and video on demand) - onto a single network infrastructure. By placing all communications into digitized packets, convergence makes it easier to combine communications into new or more cost-effective applications, while helping telecommunications companies reduce capital and operational expenses.

The tendency for prices of physical commodities and futures to approach one another, usually during the delivery month.

The independent evolution of similar genetic or phenotypic traits.

A video term that describes the way in which the three beams that generate the three color dots (red, green, blue) should meet. When all three dots are excited at the same time and their relative distance is perfect, the result is pure white. Deviation from this harmony (due to an incorrect relationship of the beams to each other) results in poor convergence. This causes white pixels to show bits of color and can decrease image sharpness and resolution.

The movement of futures price towards the true price of a commodity as the expiration date approaches.

The tendency in disasters for persons, material, and communications to flow towards the disaster site. See also informational convergence; material convergence; personal convergence.

Convergence in a horizontal wind field indicates that more air is entering a given area than is leaving at that level. To compensate for the resulting "excess," vertical motion may result: upward forcing if convergence is at low levels, or downward forcing ( subsidence) if convergence is at high levels. Upward forcing from low-level convergence increases the potential for thunderstorm development.

When communications technologies are combined, and all transmissions travel over a single network, rather than separate networks for voice and for data.

The term for horizontal air currents merging together or approaching a single point, such as at the center of a low pressure area producing a net inflow of air. When this occures in the lower atmosphere, the excess air is removed by rising air currents. Expansion of the rising air above a convergence zone results in cooling, which in turn often gives condensation (clouds) and sometimes precipitation.

In evolutionary biology, the independent formation of similar characteristics in different lineages.

The blurring of telecommunications, computers, and the Internet into one network. It is primarily about technology and the class of voice and data networks but it is also a fundamental change in the way people will work and behave in the future. The public voice network will become a public multimedia network and the Internet as it is known today will cease to exist as every user will always be on-line (no dial-up required) and have ready access.

Internet phones, net meetings, Internet radio stations and demand video are all examples of convergent media. AOL's acquisition of Time-Warner and AT&T's acquisition of Excite@Home and much of the nation's cable companies are very high-stakes gambles on the future of convergent media.

The process by which different cultural traits from different areas become similar or merge.

in a colour CRT, the alignment of electron beamd such that each will come together at an aperture in the CRT's shadow mask.

The ability of both eyes to turn inwards together. This enables both eyes to be looking at the exact same point in space. This skill is essential to being able to pay adequate attention at near to be able to read. Not only is convergence essential to maintaining attention and single vision, it is vital to be able to maintain convergence comfortably for long periods of time. For good binocular skills it is also to be able to look further away. This is called divergence. Sustained ability to make rapid convergence and divergence movements are vital skills for learning. See jump convergence.

In front or rear projection devices using combined red, green and blue images to form the final picture, it is necessary that all three be perfectly aligned, or converged, with each other in order to maximize the sharpness and color accuracy of the picture.
