Address space

In computing, an address space defines a range of discrete addresses, each of which may correspond to a network host, peripheral device, disk sector, a memory cell or other logical or physical entity.

Overview

For software programs to save and retrieve data, each unit of data must have an address where it can be individually located. The number of address spaces available will depend on the underlying address structure and these will usually be limited.

Address spaces are created by combining enough uniquely identified qualifiers to make an address unambiguous (within a particular address space). For a person's physical address, the address space would be a combination of locations, such as a neighborhood, town, city, or country. Some elements of an address space may be the same– but if any element in the address is different than addresses in said space will reference different entities. An example could be that there are multiple buildings at the same address of "32 Main Street" but in different towns, demonstrating that different towns have different, although similarly arranged, street address spaces.

Enhanced 9-1-1

Enhanced 911, E-911 or E911 is a system used in North America that links emergency callers with the appropriate public resources. Three-digit emergency telephone numbers originated in the United Kingdom in 1937 and have spread to continents and countries around the globe. Other easy dial codes, including the 112 number adopted by the European Union in 1991, have been deployed to provide free-of-charge emergency calls.

In North America, where 9-1-1 was chosen as the easy access code, the system tries to automatically associate a location with the origin of the call. This location may be a physical address or other geographic reference information such as X/Y map coordinates. The caller's telephone number is used in numerous manners to track a location that can be used to dispatch police, fire, emergency medical and other response resources. Automatic location of the emergency makes it faster to locate the required resources during fires, break-ins, kidnappings, and other events where communicating one's location is difficult or impossible.

FAQ

Frequently asked questions (FAQ) or Questions and Answers (Q&A), are listed questions and answers, all supposed to be commonly asked in some context, and pertaining to a particular topic. The format is commonly used on email mailing lists and other online forums, where certain common questions tend to recur.

"FAQ" is pronounced as either an initialism (F-A-Q) or an acronym. Since the acronym FAQ originated in textual media, its pronunciation varies; "F-A-Q",and "fack", are commonly heard. Depending on usage, the term may refer specifically to a single frequently asked question, or to an assembled list of many questions and their answers. Web page designers often label a single list of questions as a "FAQ", such as on Google.com, while using "FAQs" to denote multiple lists of questions such as on United States Treasury sites.

Origins

While the name may be recent, the FAQ format itself is quite old. For instance, Matthew Hopkins wrote The Discovery of Witches in 1647 as a list of questions and answers, introduced as "Certaine Queries answered". Many old catechisms are in a question-and-answer (Q&A) format. Summa Theologica, written by Thomas Aquinas in the second half of the 13th century, is a series of common questions about Christianity to which he wrote a series of replies. Plato's dialogues are even older.

FAQs (film)

FAQs is a 2005 LGBT-themed independent film. It was written and directed by Everett Lewis. The film tells the story of a group of young queer kids who have been discarded by straight society. They come together to form a de facto family under the wing of an African American vigilante drag queen named Destiny.

FAQs premiered at the 2005 Philadelphia International Gay & Lesbian Film Festival and had a limited theatrical release in 2006. While mainstream critics praised a number of the performances and certain aspects of the film, generally critical response was negative.
