The ITU Telecommunication Standardization Sector (ITU-T) coordinates standards for telecommunications and Information Communication Technology such as X.509 for cybersecurity, Y.3172 for machine learning, and H.264/MPEG-4 AVC for video compression, between its Member States, Private Sector Members, and Academia Members. ITU-T is one of the three Sectors of the International Telecommunication Union (ITU).
The International Organization for Standardization is an international standard-setting body composed of representatives from various national standards organizations. In contrast to many international organizations, which utilize the British English form of spelling, the ISO uses English with Oxford spelling as one of its official languages along with French and Russian.
In digital computers, an interrupt is a response by the processor to an event that needs attention from the software. An interrupt condition alerts the processor and serves as a request for the processor to interrupt the currently executing code when permitted, so that the event can be processed in a timely manner. If the request is accepted, the processor responds by suspending its current activities, saving its state, and executing a function called an interrupt handler to deal with the event. This interruption is temporary, and, unless the interrupt indicates a fatal error, the processor resumes normal activities after the interrupt handler finishes.
Real-time computing (RTC), or reactive computing is the computer science term for hardware and software systems subject to a "real-time constraint", for example from event to system response. Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines".
Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services over the public Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS).
A standards organization, standards body, standards developing organization (SDO), or standards setting organization (SSO) is an organization whose primary activities are developing, coordinating, promulgating, revising, amending, reissuing, interpreting, or otherwise producing technical standards that are intended to address the needs of a group of affected adopters.
Flextime is a flexible hours schedule that allows workers to alter workday start and finish times. In contrast to traditional work arrangements that require employees to work a standard 9 a.m. to 5 p.m. day, flextime typically involves a "core" period of the day during which employees are required to be at work, and a "bandwidth" period within which all required hours must be worked. The working day outside of the "core" period is "flexible time", in which employees can choose when they work, subject to achieving total daily, weekly or monthly hours within the "bandwidth" period set by employers, and subject to the necessary work being done. The total working time required of employees on flextime schedules is the same as that required under traditional work schedules. A flextime policy allows staff to determine when they will work, while a flexplace policy allows staff to determine where they will work. Advantages include allowing employees to coordinate their work hours with public transport schedules, with the schedules of their children, and with daily traffic patterns to avoid high congestion times such as rush hour. Some claim that flexible working will change the nature of the way we work. The idea of flextime was invented by Christel Kammerer.
Radiotelephony procedure includes various techniques used to clarify, simplify and standardize spoken communications over two-way radios, in use by the armed forces, in civil aviation, police and fire dispatching systems, citizens' band radio (CB), and amateur radio.
Universal Business Language (UBL) is an open library of standard electronic XML business documents for procurement and transportation such as purchase orders, invoices, transport logistics and waybills. UBL was developed by an OASIS Technical Committee with participation from a variety of industry data standards organizations. UBL is designed to plug directly into existing business, legal, auditing, and records management practices. It is designed to eliminate the re-keying of data in existing fax- and paper-based business correspondence and provide an entry point into electronic commerce for small and medium-sized businesses.
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design. It confirms that the aircraft of a new type intended for serial production, is in compliance with applicable airworthiness requirements established by the national air law.
The European Union adopts legislation through a variety of legislative procedures. The procedure used for a given legislative proposal depends on the policy area in question. Most legislation needs to be proposed by the European Commission and approved by the Council of the European Union and European Parliament to become law.
Data retention defines the policies of persistent data and records management for meeting legal and business data archival requirements. Although sometimes interchangeable, it is not to be confused with the Data Protection Act 1998.
A standard operating procedure (SOP) is a set of step-by-step instructions compiled by an organization to help workers carry out complex routine operations. SOPs aim to achieve efficiency, quality output and uniformity of performance, while reducing miscommunication and failure to comply with industry regulations.
When writing firmware for an embedded system, immunity-aware programming refers to programming techniques which improve the tolerance of transient errors in the program counter or other modules of a program that would otherwise lead to failure. Transient errors are typically caused by single event upsets, insufficient power, or by strong electromagnetic signals transmitted by some other "source" device.
ictQATAR, the Supreme Council of Information & Communication Technology, is Qatar's independent telecommunications regulator and the Government's technology advocate and facilitator. The Emir Sheikh Hamad bin Khalifa Al-Thani, established ictQATAR, in 2004, to accelerate the transformation of Qatar into an information-based society. In June 2013, the Ministry of Information and Communications Technology (ictQATAR) was established within the new cabinet formation announced to be an extension of the Supreme Council of Information and Communication Technology.
The e-Commerce Directive, adopted in 2000, sets up an Internal Market framework for online services. Its aim is to remove obstacles to cross-border online services in the EU internal market and provide legal certainty for businesses and consumers. It establishes harmonized rules on issues such as the transparency and information requirements for online service providers; commercial communications; and electronic contracts and limitations of liability of intermediary service providers. Finally, the Directive encourages the drawing up of voluntary codes of conduct and includes articles to enhance cooperation between Member States. Twenty years after its passage, there is wide-ranging discussion, especially in the European Parliament, about how to revise this directive in anticipation of the Digital Services Act.
A technical standard is an established norm or requirement for a repeatable technical task. It is usually a formal document that establishes uniform engineering or technical criteria, methods, processes, and practices. In contrast, a custom, convention, company product, corporate standard, and so forth that becomes generally accepted and dominant is often called a de facto standard.
In computing, an emulator is hardware or software that enables one computer system to behave like another computer system. An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate another program or device. Many printers, for example, are designed to emulate HP LaserJet printers because so much software is written for HP printers. If a non-HP printer emulates an HP printer, any software written for a real HP printer will also run in the non-HP printer emulation and produce equivalent printing. Since at least the 1990s, many video game enthusiasts have used emulators to play classic arcade games from the 1980s using the games' original 1980s machine code and data, which is interpreted by a current-era system.
In computing, input/output or I/O is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals or data received by the system and outputs are the signals or data sent from it. The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation.
A trust service provider (TSP) is a person or legal entity providing and preserving digital certificates to create and validate electronic signatures and to authenticate their signatories as well as websites in general. Trust service providers are qualified certificate authorities required in the European Union and in Switzerland in the context of regulated electronic signing procedures.
