Samsung Galaxy S21 Ultra 5G 128GB in Phantom Silver (Verizon)(SM-G998UZSAVZW)

In telecommunications, 5G is the fifth generation of cellular network technology, which mobile operators began deploying worldwide in 2019 as the successor to 4G. 5G is based on standards defined by the International Telecommunication Union (ITU) under the IMT-2020 requirements, which outline performance targets for speed, latency, and connectivity to support advanced use cases.

Like their predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and the telephone network by radio waves through a base station and antennae in the cell. The new networks offer not only higher download speeds, with a peak speed of 10 gigabits per second (Gbit/s) when there is only one user in the network, but also significantly lower latency, enabling near-instantaneous communication. 5G networks have higher bandwidth, allowing them to connect more devices simultaneously and improving the quality of Internet services in crowded areas. These features make 5G particularly suited for applications requiring real-time data exchange, such as extended reality (XR), autonomous vehicles, remote surgery, and industrial automation. Additionally, the increased bandwidth is expected to drive the adoption of 5G as a general Internet service provider (ISP), particularly through fixed wireless access (FWA), competing with existing technologies such as cable Internet, while also facilitating new applications in the Internet of Things (IoT) and machine-to-machine communication.

The increased bandwidth and lower latency of 5G networks enable highly responsive, large-scale IoT deployments, supporting diverse applications such as smart cities, connected infrastructure, industrial IoT, and automated manufacturing processes. Unlike 4G, which was primarily designed for mobile broadband, 5G can handle millions of IoT devices with stringent performance requirements, such as real-time sensor data processing and edge computing.

5G networks also extend beyond terrestrial infrastructure, incorporating non-terrestrial networks (NTN) such as satellites and high-altitude platforms, to provide global coverage, including remote and underserved areas.

Despite its performance improvements, 5G deployment faces challenges such as significant infrastructure investment, spectrum allocation, security risks, and concerns about energy efficiency and environmental impact associated with the use of higher frequency bands. However, it is expected to drive advancements in sectors like healthcare, transportation, and entertainment.

Devices with 4G capabilities are not compatible with 5G networks due to the lack of necessary hardware to support the significant changes in network architecture and the higher frequencies used in 5G.

A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. The word is derived from the Greek galaxias (γαλαξίας), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a thousand stars, to the largest galaxies known – supergiants with one hundred trillion stars, each orbiting its galaxy's center of mass. Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies.

Galaxies are categorised according to their visual morphology as elliptical, spiral, or irregular. The Milky Way is an example of a spiral galaxy. It is estimated that there are between 200 billion (2×10¹¹) to 2 trillion galaxies in the observable universe. Most galaxies are 1,000 to 100,000 parsecs in diameter (approximately 3,000 to 300,000 light years) and are separated by distances in the order of millions of parsecs (or megaparsecs). For comparison, the Milky Way has a diameter of at least 26,800 parsecs (87,400 ly) and is separated from the Andromeda Galaxy, its nearest large neighbour, by just over 750,000 parsecs (2.5 million ly).

The space between galaxies is filled with a tenuous gas (the intergalactic medium) with an average density of less than one atom per cubic metre. Most galaxies are gravitationally organised into groups, clusters and superclusters. The Milky Way is part of the Local Group, which it dominates along with the Andromeda Galaxy. The group is part of the Virgo Supercluster. At the largest scale, these associations are generally arranged into sheets and filaments surrounded by immense voids. Both the Local Group and the Virgo Supercluster are contained in a much larger cosmic structure named Laniakea.

Phantom, phantoms, or the phantom may refer to:

• Spirit (metaphysics), the vital principle or animating force within all living things
  • Ghost, the soul or spirit of a dead person or animal that can appear to the living
    • Discord User, The best Guy on Discord now Known as Phany.

Samsung Group (Korean: 삼성; Hanja: 三星; RR: samseong [samsʌŋ]; stylised as SΛMSUNG) is a South Korean multinational manufacturing conglomerate headquartered in Samsung Digital City, Suwon, South Korea. It comprises numerous affiliated businesses, most of them united under the Samsung brand, and is the largest South Korean chaebol (business conglomerate). As of 2024, Samsung has the world's fifth-highest brand value.

Samsung was founded by Lee Byung-chul in 1938 as a trading company. Over the next three decades, the group diversified into areas including food processing, textiles, insurance, securities, and retail. Samsung entered the electronics industry in the late 1960s and the construction and shipbuilding industries in the mid-1970s; these areas would drive its subsequent growth. Following Lee's death in 1987, Samsung was separated into five business groups – Samsung Group, Shinsegae Group, CJ Group, Hansol Group, and JoongAng Group.

Samsung industrial affiliates include Samsung Electronics, Samsung Heavy Industries, Samsung Engineering and Samsung C&T Corporation. Other subsidiaries include Samsung Life Insurance and Cheil Worldwide. Notable Samsung industrial affiliates include Samsung Electronics (the world's largest information technology company, consumer electronics maker and chipmaker measured by 2017 revenues), Samsung Heavy Industries (the world's second largest shipbuilder measured by 2010 revenues), and Samsung Engineering and Samsung C&T Corporation (respectively the world's 13th and 36th largest construction companies). Other notable subsidiaries include Samsung Life Insurance (the world's 14th largest life insurance company), Samsung Everland (operator of Everland Resort, the oldest theme park in South Korea) and Cheil Worldwide (the world's 15th largest advertising agency, as measured by 2012 revenues).

Silver is a chemical element; it has symbol Ag (from Latin argentum 'silver', derived from Proto-Indo-European *h₂erǵ 'shiny, white') and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.

Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures.

Other than in currency and as an investment medium (coins and bullion), silver is used in solar panels, water filtration, jewellery, ornaments, high-value tableware and utensils (hence the term "silverware"), in electrical contacts and conductors, in specialised mirrors, window coatings, in catalysis of chemical reactions, as a colorant in stained glass, and in specialised confectionery. Its compounds are used in photographic and X-ray film. Dilute solutions of silver nitrate and other silver compounds are used as disinfectants and microbiocides (oligodynamic effect), added to bandages, wound-dressings, catheters, and other medical instruments.

Verizon Communications Inc. ( və-RY-zən), is an American telecommunications company headquartered in New York City. It is the world's second-largest telecommunications company by revenue and its mobile network is the largest wireless carrier in the United States, with 114.2 million subscribers (and roughly 17th largest globally) as of September 30, 2024.

The company was formed in 1984 as Bell Atlantic as a result of the breakup of the Bell System into seven companies, each a Regional Bell Operating Company (RBOC), commonly referred to as "Baby Bells." The company was originally headquartered in Philadelphia and operated in the states of Pennsylvania, New Jersey, Delaware, Maryland, Virginia, and West Virginia.

In 1997, Bell Atlantic expanded into New York and the New England states by merging with fellow Baby Bell NYNEX. While Bell Atlantic was the surviving company, the merged company moved its headquarters from Philadelphia to NYNEX's old headquarters in New York City. In 2000, Bell Atlantic acquired GTE, which operated telecommunications companies across most of the rest of the country not already in Bell Atlantic's footprint. Bell Atlantic, the surviving entity, changed its name to Verizon, a portmanteau of veritas (Latin for "truth") and horizon.

In 2015, Verizon expanded into content ownership by acquiring AOL, and two years later, it acquired Yahoo! Inc. AOL and Yahoo were amalgamated into a new division named Oath Inc., which was rebranded as Verizon Media in January 2019, and was spun off and rebranded to Yahoo! Inc. after its sale to Apollo Global Management.

As of 2016, Verizon is one of three remaining companies with roots in the former Baby Bells. The other two, like Verizon, exist as a result of mergers among fellow former Baby Bell members. SBC Communications bought the Bells' former parent AT&T Corporation and took on the AT&T name, and CenturyLink acquired Qwest (formerly US West) in 2011 and later became Lumen Technologies in 2020.
