Piggybacking (internet Access)
Piggybacking on Internet access is the practice of establishing a wireless Internet connection by using another subscriber's wireless Internet access service without the subscriber's explicit permission or knowledge. It is a legally and ethically controversial practice, with laws that vary by jurisdiction around the world. While completely outlawed or regulated in some places, it is permitted in others. A customer of a business providing hotspot service, such as a hotel or café, is generally not considered to be piggybacking, though non-customers or those outside the premises who are simply in reach may be. Many such locations provide wireless Internet access as a free or paid-for courtesy to their patrons or simply to draw people to the area. Others near the premises may be able to gain access. Piggybacking is distinct from wardriving, which involves only the logging or mapping of the existence of access points. Background Piggybacking has become a widespread practice in t ...

Wi-Fi @ NYPL
Wi-Fi () is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for Wireless LAN, local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in small office/home office, home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, restaurants, hotels, libraries, and airports. ''Wi-Fi'' is a trademark of the Wi-Fi Alliance, which restricts the use of the term "''Wi-Fi Certified''" to products that successfully complete Interoperability Solutions for European Public Administrations, interoperability certification testing. Non-compliant hardware is simply referred to as WLAN, and it may or may not work with "''Wi-Fi Certified''" devices. the Wi-Fi Alliance consisted of more than 800 companies from ar ...

Wired Equivalent Privacy
Wired Equivalent Privacy (WEP) is an obsolete, and insecure security algorithm for 802.11 wireless networks. It was introduced as part of the original IEEE 802.11 standard ratified in 1997. The intention was to provide a level of security and privacy comparable to that of a traditional wired network. WEP, recognizable by its key of 10 or 26 hexadecimal digits (40 or 104 bits), was at one time widely used, and was often the first security choice presented to users by router configuration tools. After a severe design flaw in the algorithm was disclosed in 2001, WEP was no longer considered a secure method of wireless connection; however, in the vast majority of cases, Wi-Fi hardware devices relying on WEP security could not be upgraded to secure operation. Some of WEP's design flaws were addressed in WEP2, but it also proved insecure, and never saw wide adoption or standardization. In 2003, the Wi-Fi Alliance announced that WEP and WEP2 had been superseded by Wi-Fi Protected Acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channel Capacity
Channel capacity, in electrical engineering, computer science, and information theory, is the theoretical maximum rate at which information can be reliably transmitted over a communication channel. Following the terms of the noisy-channel coding theorem, the channel capacity of a given Channel (communications), channel is the highest information rate (in units of information entropy, information per unit time) that can be achieved with arbitrarily small error probability. Information theory, developed by Claude E. Shannon in 1948, defines the notion of channel capacity and provides a mathematical model by which it may be computed. The key result states that the capacity of the channel, as defined above, is given by the maximum of the mutual information between the input and output of the channel, where the maximization is with respect to the input distribution. The notion of channel capacity has been central to the development of modern wireline and wireless communication system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apartment Building
An apartment (American English, Canadian English), flat (British English, Indian English, South African English), tenement ( Scots English), or unit (Australian English) is a self-contained housing unit (a type of residential real estate) that occupies part of a building, generally on a single story. There are many names for these overall buildings (see below). The housing tenure of apartments also varies considerably, from large-scale public housing, to owner occupancy within what is legally a condominium ( strata title or commonhold) or leasehold, to tenants renting from a private landlord. Terminology The term ''apartment'' is favoured in North America (although in some Canadian cities, ''flat'' is used for a unit which is part of a house containing two or three units, typically one to a floor). In the UK and Australia, the term ''apartment'' is more usual in professional real estate and architectural circles where otherwise the term ''flat'' is used commonly, bu ...

Cable Television
Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over-the-air by radio waves and received by a television antenna, or satellite television, in which the television signal is transmitted over-the-air by radio waves from a communications satellite and received by a satellite dish on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation. A cable channel (sometimes known as a cable network) is a television network available via cable television. Many of the same channels are distributed throug ...

Slate (magazine)
''Slate'' is an online magazine that covers current affairs, politics, and culture in the United States. It was created in 1996 by former '' New Republic'' editor Michael Kinsley, initially under the ownership of Microsoft as part of MSN. In 2004, it was purchased by The Washington Post Company (later renamed the Graham Holdings Company), and since 2008 has been managed by The Slate Group, an online publishing entity created by Graham Holdings. ''Slate'' is based in New York City, with an additional office in Washington, D.C. ''Slate'', which is updated throughout the day, covers politics, arts and culture, sports, and news. According to its former editor-in-chief Julia Turner, the magazine is "not fundamentally a breaking news source", but rather aimed at helping readers to "analyze and understand and interpret the world" with witty and entertaining writing. As of mid-2015, it publishes about 1,500 stories per month. A French version, ''slate.fr'', was launched in Februa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drinking Fountain
A drinking fountain, also called a water fountain or water bubbler, is a fountain designed to provide drinking water. It consists of a basin with either continuously running water or a tap. The drinker bends down to the stream of water and swallows water directly from the stream. Modern indoor drinking fountains may incorporate filters to remove impurities from the water and chillers to lower its temperature. Drinking fountains are usually found in public places, like schools, rest areas, libraries, and grocery stores. Drinking fountains are an important source of clean water in urban infrastructure. Many jurisdictions require drinking fountains to be wheelchair accessible (by sticking out horizontally from the wall), and to include an additional unit of a lower height for children and short adults. The design that this replaced often had one spout atop a refrigeration unit. History Before potable water was provided in private homes, water for drinking was made available t ...

Newspaper
A newspaper is a Periodical literature, periodical publication containing written News, information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports, art, and science. They often include materials such as opinion columns, weather forecasts, reviews of local services, Obituary, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of Subscription business model, subscription revenue, Newsagent's shop, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often Metonymy, metonymically called newspapers. Newspapers have traditionally been published Printing, in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also Electronic publishing, published on webs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train
A train (from Old French , from Latin">-4; we might wonder whether there's a point at which it's appropriate to talk of the beginnings of French, that is, when it wa ... , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and Passenger train, transport people or Rail freight transport, freight. Trains are typically pulled or pushed by locomotives (often known simply as "engines"), though some are self-propelled, such as multiple units or railcars. Passengers and cargo are carried in railroad cars, also known as wagons or carriages. Trains are designed to a certain gauge, or distance between rails. Most trains operate on steel tracks with steel wheels, the low friction of which makes them more efficient than other forms of transport. Many countries use rail transport. Trains have their roots in wagonways, which used railway tracks and were powered by horses or pulled by cables. Following the invention of the steam locomo ...

Legality Of Piggybacking
Laws regarding "unauthorized access of a computer network" exist in many legal codes, though the wording and meaning differs from one to the next. However, the interpretation of terms like "access" and "authorization" is not clear, and there is no general agreement on whether piggybacking (intentional access of an open Wi-Fi network without harmful intent) falls under this classification. Some jurisdictions prohibit it, some permit it, and others are not well-defined. For example, a common but untested argument is that the 802.11 and DHCP protocols operate on behalf of the owner, implicitly requesting permission to access the network, which the wireless router then authorizes. (This would not apply if the user has other reason to know that their use is unauthorized, such as a written or unwritten notice.) In addition to laws against unauthorized access on the user side, there are the issues of breach of contract with the Internet service provider on the network owner's side ...

HADOPI Law
The French HADOPI law (, English: "Supreme Authority for the Distribution of Works and Protection of Copyright on the Internet") or Creation and Internet law () was introduced during 2009, providing what is known as a graduated response as a means to encourage compliance with copyright laws. HADOPI is the acronym of the government agency created to administer it. The part of the ''HADOPI law'' that allowed for suspension of Internet access to a repeat infringer was revoked on 8 July 2013 by the French government because that penalty was considered to be disproportionate. The power to impose fines or other sanctions on repeat infringers remains in effect. In January 2022, the Hadopi agency merged with the High Audiovisual Council (CSA), to form the Regulatory Authority for Audiovisual and Digital Communication (; ARCOM). Legislative passage Despite strong backing from President Nicolas Sarkozy, the bill was rejected by the French National Assembly on 9 April 2009. The French g ...

Legal Liability
In law, liable means "responsible or answerable in law; legally obligated". Legal liability concerns both Civil law (common law), civil law and criminal law and can arise from various areas of law, such as contracts, torts, taxes, or fines given by Administrative law, government agencies. The Plaintiff, claimant is the one who seeks to establish, or prove, liability. Liability in business In commercial law, limited liability is a method of protection included in some business formations that shields its owners from certain types of liability and that amount a given owner will be liable for. A limited liability form separates the owner(s) from the business. The limited liability form essentially acts as a corporate veil that protects owners from liabilities of the business. This means that when a business is found liable in a case, the owners are not themselves liable; rather, the business is. Thus, only the funds or property the owner(s) have invested into the business are subje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
