0 (zero) is a number representing an empty quantity. Adding 0 to any number leaves that number unchanged. In mathematical terminology, 0 is the additive identity of the integers, rational numbers, real numbers, and complex numbers, as well as other algebraic structures. Multiplying any number by 0 has the result 0, and consequently, division by zero has no meaning in arithmetic.

As a numerical digit, 0 plays a crucial role in decimal notation: it indicates that the power of ten corresponding to the place containing a 0 does not contribute to the total. For example, "205" in decimal means two hundreds, no tens, and five ones. The same principle applies in place-value notations that uses a base other than ten, such as binary and hexadecimal. The modern use of 0 in this manner derives from Indian mathematics that was transmitted to Europe via medieval Islamic mathematicians and popularized by Fibonacci. It was independently used by the Maya.

Common names for the number 0 in English include zero, nought, naught (), and nil. In contexts where at least one adjacent digit distinguishes it from the letter O, the number is sometimes pronounced as oh or o (). Informal or slang terms for 0 include zilch and zip. Historically, ought, aught (), and cipher have also been used.

Year 215 (CCXV) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Laetus and Sulla (or, less frequently, year 968 Ab urbe condita). The denomination 215 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies.

32 may refer to:

• 32 (number), the natural number following 31 and preceding 33
• one of the years 32 BC, AD 32, 1832, 1932, 2032

600 (DC) was a leap year starting on Friday (link will display the full calendar) of the Julian calendar. The denomination 600 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

A charter is the grant of authority or rights, stating that the granter formally recognizes the prerogative of the recipient to exercise the rights specified. It is implicit that the granter retains superiority (or sovereignty), and that the recipient admits a limited (or inferior) status within the relationship, and it is within that sense that charters were historically granted, and it is that sense which is retained in modern usage of the term. In early medieval Britain, charters transferred land from donors to recipients.

The word entered the English language from the Old French charte, via Latin charta, and ultimately from Greek χάρτης (khartes, meaning "layer of papyrus"). It has come to be synonymous with a document that sets out a grant of rights or privileges.

Comcast Corporation, formerly known as Comcast Holdings, is an American multinational telecommunications and media conglomerate incorporated and headquartered in Philadelphia.

It is the fourth-largest broadcasting and cable television company worldwide by revenue (behind China Mobile, Verizon, and AT&T). It is the third-largest pay-TV company, the second-largest cable TV company by subscribers, and the largest home Internet service provider in the United States. In 2023, the company was ranked 51st in the Forbes Global 2000. Comcast is additionally the nation's third-largest home telephone service provider. It provides services to U.S. residential and commercial customers in 40 states and the District of Columbia. As the owner of NBCUniversal since 2011, Comcast is also a high-volume producer of films for theatrical exhibition and television programming, and a theme parks operator. It is the fourth-largest telecommunications company by worldwide revenue.

Comcast owns and operates the Xfinity residential cable communications business segment and division; Comcast Business, a commercial services provider; and Xfinity Mobile, an MVNO of Verizon. Through NBCUniversal, Comcast is also the owner and operator of over-the-air national broadcast network channels such as NBC, Telemundo, TeleXitos, and Cozi TV; multiple cable-only channels such as MSNBC, CNBC, USA Network, Syfy, Oxygen, Bravo, and E!; the film studio Universal Pictures; the VOD streaming service Peacock; animation studios DreamWorks Animation, Illumination, and Universal Animation Studios; and Universal Destinations & Experiences. It also has significant holdings in digital distribution, such as thePlatform, which it acquired in 2006; and ad-tech company FreeWheel, which it acquired in 2014. Since October 2018, Comcast is also the parent company of Sky Group.

Comcast is criticized and put under intense public scrutiny for a variety of reasons. Its customer satisfaction ratings were among the lowest in the cable industry during the years 2008–2010. It has violated net neutrality practices in the past and despite its commitment to a narrow definition of net neutrality, critics advocate a definition that precludes any distinction between Comcast's private network services and the rest of the Internet. Critics also point out a lack of competition in the vast majority of Comcast's service areas; in particular, the limited competition among cable providers. Given its negotiating power as a large ISP, some suspect that it could leverage paid peering agreements to unfairly influence end-user connection speeds. Its ownership of both content production (in NBCUniversal) and distribution (as an ISP) has raised antitrust concerns. These issues and others led to Comcast being dubbed "The Worst Company in America" by The Consumerist in 2010 and 2014.

Cox or COX may refer to:

• Cox (surname), including people with the name

Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable television (CATV) system. It is used by many cable television operators to provide cable Internet access over their existing hybrid fiber-coaxial (HFC) infrastructure.

DOCSIS was originally developed by CableLabs and contributing companies, including Arris, BigBand Networks, Broadcom, Cisco, Comcast, Conexant, Correlant, Cox, General Instrument, Harmonic, Intel, Motorola, Netgear, Terayon, Time Warner Cable, and Texas Instruments.

The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists 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 a vast range of information resources and services, such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.

The origins of the Internet date back to research that enabled the time-sharing of computer resources, the development of packet switching in the 1960s and the design of computer networks for data communication. The set of rules (communication protocols) to enable internetworking on the Internet arose from research and development commissioned in the 1970s by the Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense in collaboration with universities and researchers across the United States and in the United Kingdom and France. The ARPANET initially served as a backbone for the interconnection of regional academic and military networks in the United States to enable resource sharing. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, encouraged worldwide participation in the development of new networking technologies and the merger of many networks using DARPA's Internet protocol suite. The linking of commercial networks and enterprises by the early 1990s, as well as the advent of the World Wide Web, marked the beginning of the transition to the modern Internet, and generated sustained exponential growth as generations of institutional, personal, and mobile computers were connected to the network. Although the Internet was widely used by academia in the 1980s, the subsequent commercialization in the 1990s and beyond incorporated its services and technologies into virtually every aspect of modern life.

Most traditional communication media, including telephone, radio, television, paper mail, and newspapers, are reshaped, redefined, or even bypassed by the Internet, giving birth to new services such as email, Internet telephone, Internet television, online music, digital newspapers, and video streaming websites. Newspapers, books, and other print publishing have adapted to website technology or have been reshaped into blogging, web feeds, and online news aggregators. The Internet has enabled and accelerated new forms of personal interaction through instant messaging, Internet forums, and social networking services. Online shopping has grown exponentially for major retailers, small businesses, and entrepreneurs, as it enables firms to extend their "brick and mortar" presence to serve a larger market or even sell goods and services entirely online. Business-to-business and financial services on the Internet affect supply chains across entire industries.

The Internet has no single centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own policies. The overarching definitions of the two principal name spaces on the Internet, the Internet Protocol address (IP address) space and the Domain Name System (DNS), are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise. In November 2006, the Internet was included on USA Today's list of the New Seven Wonders.

A modulator-demodulator, commonly referred to as a modem, is a computer hardware device that converts data from a digital format into a format suitable for an analog transmission medium such as telephone or radio. A modem transmits data by modulating one or more carrier wave signals to encode digital information, while the receiver demodulates the signal to recreate the original digital information. The goal is to produce a signal that can be transmitted easily and decoded reliably. Modems can be used with almost any means of transmitting analog signals, from light-emitting diodes to radio.

Early modems were devices that used audible sounds suitable for transmission over traditional telephone systems and leased lines. These generally operated at 110 or 300 bits per second (bit/s), and the connection between devices was normally manual, using an attached telephone handset. By the 1970s, higher speeds of 1,200 and 2,400 bit/s for asynchronous dial connections, 4,800 bit/s for synchronous leased line connections and 35 kbit/s for synchronous conditioned leased lines were available. By the 1980s, less expensive 1,200 and 2,400 bit/s dialup modems were being released, and modems working on radio and other systems were available. As device sophistication grew rapidly in the late 1990s, telephone-based modems quickly exhausted the available bandwidth, reaching 56 kbit/s.

The rise of public use of the internet during the late 1990s led to demands for much higher performance, leading to the move away from audio-based systems to entirely new encodings on cable television lines and short-range signals in subcarriers on telephone lines. The move to cellular telephones, especially in the late 1990s and the emergence of smartphones in the 2000s led to the development of ever-faster radio-based systems. Today, modems are ubiquitous and largely invisible, included in almost every mobile computing device in one form or another, and generally capable of speeds on the order of tens or hundreds of megabytes per second.
