Statistical Terms Glossary

OECD.Stat is the OECD’s central data repository (“warehouse”) where validated statistics and related metadata are stored.

Is a term used by many local authorities in the United Kingdom to describe the facility they offer for their residents to discuss and arrange services with officers of the authority.

State of a mobile user or terminal that has "logged on", i.e. is currently registered at a gatekeeper, as opposed to absent or "logged off".

Designed for use by a provider of on-line services, it covers the nature of the service to be provided, the right of the service provider to restrict access, to change its operating procedures, or to modify the rules of access for the on-line service. Where users may upload information to the service, the service provider will also address issues of ownership of proprietary rights and editorial control over the uploaded content, and the user’s rights of privacy in electronic communications.

Is a service offered by banks that allows account holders to access their account data via the Internet. In order to take advantage of online banking, an account holder would need to meet several technological requirements, such as having a personal computer with Internet access and web browser.

A

Is an archive, consisting of an organization of people and systems, that has accepted the responsibility to preserve information and make it available for a Designated Community.

Describes any kind of creative work, or content, published under a license that explicitly allows copying and modifying of its information by anyone, not exclusively by a closed organization, firm or individual. Open content is an alternative paradigm to the use of copyright to create monopolies; rather than leading to monopoly, open content facilitates the democratization of knowledge.

Distance learning means that you study on your own, either at home or wherever suits you. It’s ‘open’ because you learn in your own time, at home or wherever you choose – reading, watching or listening to material supplied, doing course activities and assignments with regular support from your tutor.

Provide access to knowledge without the need to pay for the knowledge itself, although there may be marginal fees for access (membership in trade associations, attendance at conferences, subscriptions to journals).

Is a dynamic routing protocol for use in Internet Protocol (IP) networks. Specifically, it is a link-state routing protocol and falls into the group of interior gateway protocols, operating within a single autonomous system (AS). It is defined as OSPF Version 2 in RFC 2328 (1998) for IPv4.

Open source describes practices in production and development that promote access to the end product's source materials—typically, their source code.[1] Some consider open source a philosophy, others consider it a pragmatic methodology. Before the term open source became widely adopted, developers and producers used a variety of phrases to describe the concept; open source gained hold with the rise of the Internet, and the attendant need for massive retooling of the computing source code. Opening the source code enabled a self-enhancing diversity of production models, communication paths, and interactive communities.

A method and philosophy for software licensing and distribution designed to encourage use and improvement of software written by volunteers by ensuring that anyone can copy the source code and modify it freely.

Is an ongoing cost for running a product, business, or system. Its counterpart, a capital expenditure (CAPEX), is the cost of developing or providing non-consumable parts for the product or system. For example, the purchase of a photocopier is the CAPEX, and the annual paper, toner, power and maintenance cost is the OPEX. For larger systems like businesses, OPEX may also include the cost of workers and facility expenses such as rent and utilities.

The OS is the system which performs OSFs. The OS may optionally provide MFs, QSFs and WSFs.

Method of converting a scanned image into a word-processing file.

Is any form of telecommunication that uses light as the transmission medium. An optical communication system consists of a transmitter, which encodes a message into an optical signal, a channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.

The optical disk system is a hierarchical system with primary storage on magnetic disk and secondary storage on the optical disks. New files are written to the write cache. Periodically the optical disk archiver copies the files from the write cache to the optical disk. This process also copies the files to the read cache and deletes them from the write cache. The PPPL utilities and libraries that access this data first check the magnetic cache. If the file is not found, the optical disk indices are searched; if the file is found, it is copied to the read cache. The data on the read cache is skimmed by access date.

A physical loop topology, either open or closed, employing two optical fiber signal paths, one in each direction (i.e. counter-rotating) forming a sequence of peer connections between FDDI nodes. When the trunk forms a closed loop, it is sometimes called a trunk ring.

Optical interconnect is a way of communication by optical cables.[1] Compared to traditional cables, optical wires are capable of a much higher bandwidth, from 10 Gb/s up to 100 Gb/s.[2] The technology is currently being researched as a way to link computers to mobile devices,[3] as well as on motherboards and devices within computers

Converts optical signals transmitted via fiber to electrical signals. These electrical signals are then sent to individual subscribers. ONUs are commonly used in fiber-to-the-home (FTTH) or fiber-to-the-curb (FTTC) applications. Silicon Laboratories' proven SLIC and Power over Ethernet solutions offer a one stop shop for high voltage ONU solutions.

In telecommunication, an optical switch is a switch that enables signals in optical fibers or integrated optical circuits (IOCs) to be selectively switched from one circuit to another.

An all-optical fiber-optic switching device that maintains the signal as light from input to output. Traditional switches that connect optical fiber lines are electro-optic. They convert photons from the input side to electrons internally in order to do the switching and then convert back to photons on the output side.

In a telecommunications network, one begins at the terminal site at the customer premises; the access part of the process is the first mile. In essence, it is the part that connects the end user to the first piece of equipment in the network.

Is a professional certification program offered by the Oracle Corporation. There are three levels of Oracle Certification in several disciplines: Oracle Certified Associate (OCA), Oracle Certified Professional (OCP), and Oracle Certified Master (OCM).

Is a multinational computer-technology corporation that specializes in developing and marketing enterprise software products — particularly database management systems. Headquartered in Redwood City, California, United States, Oracle employs more than 73,201 people worldwide as of 2009[update]. It has enlarged its share of the software market through organic growth and through a number of high-profile acquisitions.

Was established in 1972 to manage and operate the telegraph and submarine telecommunications of Radio Orient (the early 1900's company). It is 100% owned by the government and acts under the supervision of the Minister of Telecommunication.

Is an international organisation of 30 countries that accept the principles of representative democracy and free-market economy. Most OECD members are high-income economies with a high Human Development Index (HDI) and are regarded as developed countries.
