Block (Internet)

On the Internet, a block is a technical measure intended to restrict access to information or resources. Blocking may be implemented by the owners of computers using software. Some countries, including China and Singapore, block access to certain news information. In the United States, the Children's Internet Protection Act requires schools receiving federal funded discount rates for Internet access to install software that blocks obscene content, pornography, and, where applicable, content “harmful to minors”.

Blocking may also refer to denying access to a web server based on the IP address of the client machine. In certain websites, including social networks such as Facebook or editable databases like Wikimedia projects, users can apply blocks on other users (based in either IP number or account) to prevent them from performing certain actions. Blocks of this kind may occur for several reasons and produce different effects: in social networks, users can unrestrictedly block other users, typically by preventing them from sending messages or viewing the blocker's information and/or profile.

Block (periodic table)

A block of the periodic table of elements is a set of adjacent groups. The term appears to have been first used by Charles Janet. The respective highest-energy electrons in each element in a block belong to the same atomic orbital type. Each block is named after its characteristic orbital; thus, the blocks are:

The block names (s, p, d, f and g) are derived from the spectroscopic notation for the associated atomic orbitals: sharp, principal, diffuse and fundamental, and then g which follows f in the alphabet.

The following is the order for filling the "subshell" orbitals, according to the Aufbau principle, which also gives the linear order of the "blocks" (as atomic number increases) in the periodic table:

For discussion of the nature of why the energies of the blocks naturally appear in this order in complex atoms, see atomic orbital and electron configuration.

The "periodic" nature of the filling of orbitals, as well as emergence of the s, p, d and f "blocks" is more obvious, if this order of filling is given in matrix form, with increasing principal quantum numbers starting the new rows ("periods") in the matrix. Then, each subshell (composed of the first two quantum numbers) is repeated as many times as required for each pair of electrons it may contain. The result is a compressed periodic table, with each entry representing two successive elements:

The Elder Scrolls

The Elder Scrolls is a series of action role-playing open world fantasy video games primarily developed by Bethesda Game Studios and published by Bethesda Softworks. The series is known for its elaborate and richly detailed open worlds and its focus on free-form gameplay. Morrowind, Oblivion, and Skyrim all won Game of the Year awards from multiple outlets. The series has sold more than 40 million copies worldwide.

Development history

Before The Elder Scrolls

Prior to working on The Elder Scrolls series, Bethesda had worked predominantly with sports and action games. In the six years from its founding to Arena's 1994 release, Bethesda had released ten games, six of them sports games, with such titles as Hockey League Simulator, NCAA Basketball: Road to the Final Four ('91/'92 Edition), and Wayne Gretzky Hockey, and the remaining four adaptations from other media, primarily the Terminator series. Bethesda's course changed abruptly when it began its first action role-playing venture. Designer Ted Peterson recalls: "I remember talking to the guys at Sir-Tech who were doing Wizardry VII: Crusaders of the Dark Savant at the time, and them literally laughing at us for thinking we could do it." Ted Peterson worked alongside Vijay Lakshman as one of the initial designers of what was then simply Arena, a "medieval-style gladiator game."

Block (rural Australia)

Block is an Australian term for a small agricultural landholding. Block settlement has been used by Governments to encourage decentralization and during financial depressions to give families of unemployed workers an opportunity (frequently illusory) to become primary producers. It may also refer to a lifestyle choice or "hobby farm" for those with an independent source of income.

In parts of Australia, parcels of land of around 6 to 20 acres (2 to 8 ha) were allocated by Government to working-class men at nominal rent during the depression of the 1890s with the object of giving them work and, potentially, a source of income. Some eventually prospered, but those on marginal land were doomed to failure. Proponents of the "block system" included George Witherage Cotton. Holders of such allotments were referred to as "blockers" or "blockies".

Internet

The Internet is the global system of interconnected mainframe, personal, and wireless computer networks that use the Internet protocol suite (TCP/IP) to link billions of devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, Usenet newsgroups, telephony, and peer-to-peer networks for file sharing.

Although the Internet protocol suite has been used by academia and the military industrial complex since the early 1980s, rapid adoption of its use was driven by events of the late 1980s and 1990s such as more powerful and affordable computers, the advent of fiber optics, the popularization of HTTP and the Web browser, and a push towards opening the technology to commerce. Internet use grew rapidly in the West from the mid-1990s and from the late 1990s in the developing world. In the 20 years since 1995, Internet use has grown 100-times to reach over one third of the world population, leading to its services and technologies being incorporated into virtually every aspect of contemporary life. The impact of the Internet has been so immense that it has been referred to as the "8th continent".

Internet Plus

Internet Plus (Chinese: 互联网+), similar to Information Superhighway and Industry 4.0, is proposed by China’s prime minister Li Keqiang in his Government Work Report on March 5 in 2015 so as to keep pace with the Information Trend. According to China’s official website, "Internet plus" was on the list of significant economic keywords in 2015 and is one of the newest expressions of the two sessions (National People's Congress of the People's Republic of China and Chinese People's Political Consultative Conference, Chinese: 两会) of the year.

Definition

"Internet Plus" refers to the application of the internet and other information technology in conventional industries. It is an incomplete equation where various internets (mobile Internet, cloud computing, big data or Internet of Things) can be added to other fields, fostering new industries and business development in China.

Background

Domestic challenges

China’s economy is declining due to the growing debt mountains, declining factory activity and foreign exchange reserves devaluation, which has led the government to figure out a plan to create a new driver to stimulate the development for its country.
