Interoperability
Interoperability is a characteristic of a product or system to work with other products or systems. While the term was initially defined for information technology or systems engineering services to allow for information exchange, a broader definition takes into account social, political, and organizational factors that impact system-to-system performance. Types of interoperability include syntactic interoperability, where two systems can communicate with each other, and cross-domain interoperability, where multiple organizations work together and exchange information. Types If two or more systems use common data formats and communication protocols and are capable of communicating with each other, they exhibit ''syntactic interoperability''. XML and SQL are examples of common data formats and protocols. Lower-level data formats also contribute to syntactic interoperability, ensuring that alphabetical characters are stored in the same ASCII or a Unicode format in all the commun ...

Semantic Interoperability
Semantic interoperability is the ability of computer systems to exchange data with unambiguous, shared meaning. Semantic interoperability is a requirement to enable machine computable logic, inferencing, knowledge discovery, and data federation between information systems. Semantic interoperability is therefore concerned not just with the packaging of data (syntax), but the simultaneous transmission of the meaning with the data (semantics). This is accomplished by adding data about the data (metadata), linking each data element to a controlled, shared vocabulary. The meaning of the data is transmitted with the data itself, in one self-describing " information package" that is independent of any information system. It is this shared vocabulary, and its associated links to an ontology, which provides the foundation and capability of machine interpretation, inference, and logic. Syntactic interoperability (see below) is a prerequisite for semantic interoperability. Syntactic intero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross-domain Interoperability
Cross-domain interoperability exists when organizations or systems from different domains interact in information exchange, services, and/or goods to achieve their own or common goals. Interoperability is the method of systems working together (inter-operate). A domain in this instance is a community with its related infrastructure, bound by common purpose and interests, with consistent mutual interactions or rules of engagement that is separable from other communities by social, technical, linguistic, professional, legal or sovereignty related boundaries. The capability of cross-domain interoperability is becoming increasingly important as business and government operations become more global and interdependent. Cross-domain interoperability enables synergy, extends product utility and enables users to be more effective and successful within their own domains and the combined effort. Cross-domain interoperability is characterized by common understanding and agreements on both sides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open Standard
An open standard is a standard that is openly accessible and usable by anyone. It is also a prerequisite to use open license, non-discrimination and extensibility. Typically, anybody can participate in the development. There is no single definition, and interpretations vary with usage. The terms ''open'' and ''standard'' have a wide range of meanings associated with their usage. There are a number of definitions of open standards which emphasize different aspects of openness, including the openness of the resulting specification, the openness of the drafting process, and the ownership of rights in the standard. The term "standard" is sometimes restricted to technologies approved by formalized committees that are open to participation by all interested parties and operate on a consensus basis. The definitions of the term ''open standard'' used by academics, the European Union, and some of its member governments or parliaments such as Denmark, France, and Spain preclude open standard ...

Project 25
Project 25 (P25 or APCO-25) is a suite of standards for interoperable digital two-way radio products. P25 was developed by public safety professionals in North America and has gained acceptance for public safety, security, public service, and commercial applications worldwide. P25 radios are a direct replacement for analog UHF (typically FM) radios, but add the ability to transfer data as well as voice, allowing for more natural implementations of encryption and text messaging. P25 radios are commonly implemented by dispatch organizations, such as police, fire, ambulance and emergency rescue service, using vehicle-mounted radios combined with repeaters and handheld walkie-talkie use. Starting around 2012, products became available with the newer phase 2 modulation protocol, the older protocol known as P25 became P25 phase 1. P25 phase 2 products use the more advanced AMBE2+ vocoder, which allows audio to pass through a more compressed bitstream and provides two TDMA voice ch ...

Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology Technical standard, standard for the consistent character encoding, encoding, representation, and handling of Character (computing), text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic script (Unicode), scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with Universal Coded Character Set, ISO/IEC 10646, each being code-for-code id ...

Network Effect
In economics, a network effect (also called network externality or demand-side economies of scale) is the phenomenon by which the value or utility a user derives from a good or service depends on the number of users of compatible products. Network effects are typically positive, resulting in a given user deriving more value from a product as more users join the same network. The adoption of a product by an additional user can be broken into two effects: an increase in the value to all other users ( "total effect") and also the enhancement of other non-users' motivation for using the product ("marginal effect"). Network effects can be direct or indirect. Direct network effects arise when a given user's utility increases with the number of other users of the same product or technology, meaning that adoption of a product by different users is complementary. This effect is separate from effects related to price, such as a benefit to existing users resulting from price decreases as m ...

System Of Systems
System of systems is a collection of task-oriented or dedicated systems that pool their resources and capabilities together to create a new, more complex system which offers more functionality and performance than simply the sum of the constituent systems. Currently, systems of systems is a critical research discipline for which frames of reference, thought processes, quantitative analysis, tools, and design methods are incomplete. The methodology for defining, abstracting, modeling, and analyzing system of systems problems is typically referred to as system of systems engineering. Overview Commonly proposed descriptions—not necessarily definitions—of systems of systems, are outlined below in order of their appearance in the literature: # Linking systems into joint system of systems allows for the interoperability and synergism of Command, Control, Computers, Communications and Information (C4I) and Intelligence, Surveillance and Reconnaissance (ISR) Systems: ''description in ...

Communication Protocol
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics (computer science), semantics and synchronization of communication and possible Error detection and correction, error recovery methods. Protocols may be implemented by Computer hardware, hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. The specified behavior is typically independent of how it is to be Implementation, implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, ...

Information Technology
Information technology (IT) is the use of computers to create, process, store, retrieve, and exchange all kinds of data . and information. IT forms part of information and communications technology (ICT). An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system — including all hardware, software, and peripheral equipment — operated by a limited group of IT users. Although humans have been storing, retrieving, manipulating, and communicating information since the earliest writing systems were developed, the term ''information technology'' in its modern sense first appeared in a 1958 article published in the ''Harvard Business Review''; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology (IT)." Their definition consists of three categories: techniques for pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utah Highway Patrol
The Utah Highway Patrol (UHP) is the functional equivalent of state police for the State of Utah in the United States. Its sworn members, known as ''Troopers'', are certified law enforcement officers and have statewide jurisdiction. It was created to "patrol or police the highways within this state of Utah and to enforce the state statutes as required." The Utah Highway Patrol is a division of the Utah Department of Public Safety. Rank structure Issued vehicles and weapons The UHP has a mixed fleet of vehicles: Ford CVPI, Dodge Charger, Chevy Suburbans, and multiple Dodge and Ford pickups. The UHP also issues its troopers take-home cars, which can be used within of their residence. The Ford Mustang SSP was used from 1985 to 1993 and was highly reliable at the time. The Mustang was then superseded by the Ford Crown Victoria Police Interceptor. The UHP issues its Troopers the Glock 17 Gen 4 9mm caliber or Glock 18 9mm. (The Glock 18 was, for a time, issued to Section 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
9/11 Attacks
The September 11 attacks, commonly known as 9/11, were four coordinated Suicide attack, suicide List of terrorist incidents, terrorist attacks carried out by al-Qaeda against the United States on Tuesday, September 11, 2001. That morning, Hijackers in the September 11 attacks, nineteen terrorists Aircraft hijacking, hijacked four commercial Airliner, airliners scheduled to travel from the Northeastern United States to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center (1973–2001), World Trade Center in New York City, and the third plane into the Pentagon (the headquarters of the United States Department of Defense, United States military) in Arlington County, Virginia. The fourth plane was intended to hit a Federal government of the United States, federal government building in Washington, D.C., but crashed in a field following a passenger revolt. The attacks killed nearly 3,000 people and instigated the war on terror. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
