Privately Held Company
A privately held company (or simply a private company) is a company whose Stock, shares and related rights or obligations are not offered for public subscription or publicly negotiated in their respective listed markets. Instead, the Private equity, company's stock is offered, owned, traded or exchanged privately, also known as "over-the-counter (finance), over-the-counter". Related terms are unlisted organisation, unquoted company and private equity. Private companies are often less well-known than their public company, publicly traded counterparts but still have major importance in the world's economy. For example, in 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for $1.8 trillion in revenues and employed 6.2 million people, according to ''Forbes''. In general, all companies that are not owned by the government are classified as private enterprises. This definition encompasses both publ ...

Purvciems
Purvciems is a neighbourhood in the Vidzeme Suburb of Riga, Latvia. Its name literally translates as "marsh village". It is located on the east bank of the River Daugava, to the east of the City Centre and is defined roughly as the area between A. Deglava Iela and Ieriķu Iela. The area is characterised by apartment blocks from the late Soviet and the first years after the restoration of Latvian independence (1980s–1990s), though there is also some detached housing. The district is Latvian and Russian-speaking. History Starting the end of 17th century and start of 18th century, the largely unsurveyed territory was called Hausmaņa purvs ('Hausmanis' swamp/marsh'). Until the 19th century, only yeomen Yeoman is a noun originally referring either to one who owns and cultivates land or to the middle ranks of servants in an English royal or noble household. The term was first documented in mid-14th-century England. The 14th century witnessed ... lived there. In 1828, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zolitūde
Zolitūde () is mainly an apartment house neighbourhood (or microdistrict) located in the western part of Riga, the capital of Latvia. Zolitūde is a centrally planned estate, consisting mostly of prefabricated concrete block Brutalist style homes built in late Soviet times. Construction started in 1984, and was mostly halted in 1991, when Latvia obtained its independence from the USSR. Large parts of the population, as in similar neighbourhoods of Riga, are Russian speaking. Zolitūde had been a mixture of council housing and co-operative flats, but many properties have been privatised since the fall of the Soviet Union. History In 1991, Latvia regained independence from the USSR, and due to the end of financing from Moscow most of the state funded construction projects were halted. Few new homes were built until after Latvia joined the EU in 2004, but construction halted again due to the Great Recession. Due to the flow of investments and affordable housing credits from p ...

Fiber Optic
An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other. Such fibers find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables. Fibers are used instead of metal wires because signals travel along them with less loss and are immune to electromagnetic interference. Fibers are also used for illumination and imaging, and are often wrapped in bundles so they may be used to carry light into, or images out of confined spaces, as in the case of a fiberscope. Specially designed fibers are also used for a variety of other applications, such as fiber optic sensors and fiber lasers. Glass optical fibers are typically made by drawing, while plastic fibers can be made either by drawing or by extrusion. Optical fibers typically include a core surrounded by a transparent cladding material with a lower index ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wi-Fi
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 ...

GPON
ITU-T G.984 is the series of standards for implementing a gigabit-capable passive optical network (GPON). It is commonly used to implement the link to the customer (the ''last kilometre'', or ''last mile'') of fibre-to-the-premises ( FTTP) services. GPON puts requirements on the optical medium and the hardware used to access it, and defines the manner in which Ethernet frames are converted to an optical signal, as well as the parameters of that signal. The bandwidth of the single connection between the OLT ( optical line termination) and the ONTs ( optical network terminals) is 2.4Gbit/s down, 1.2Gbit/s up, or rarely symmetric 2.4Gbit/s, shared between up to 128 ONTs using a time-division multiple access (TDMA) protocol, which the standard defines. GPON specifies protocols for error correction ( Reed–Solomon) and encryption ( AES), and defines a protocol for line control ( OMCI) which includes authentication (GPON serial number and/or PLOAM password). Unlike the previous EPON ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

VDSL
Very high-speed digital subscriber line (VDSL) and very high-speed digital subscriber line 2 (VDSL2) are digital subscriber line (DSL) technologies providing data transmission faster than the earlier standards of asymmetric digital subscriber line (ADSL) G.992.1, G.992.3 (ADSL2) and G.992.5 (ADSL2+). VDSL offers speeds of up to 52 Mbit/s downstream and 16 Mbit/s upstream, over a single twisted pair of copper wires using the frequency band from 25 kHz to 12 MHz. These rates mean that VDSL is capable of supporting applications such as high-definition television, as well as telephone services (voice over IP) and general Internet access, over a single connection. VDSL is deployed over existing wiring used for analog telephone service and lower-speed DSL connections. This standard was approved by the International Telecommunication Union (ITU) in November 2001. Second-generation systems (VDSL2; ITU-T G.993.2 approved in February 2006) use frequencies of ...

ADSL2+
G.992.5 (also referred to as ADSL2+, G.dmt.bis+, and G.adslplus) is an ITU-T standard for asymmetric digital subscriber line (ADSL) broadband Internet access. The standard has a maximum theoretical downstream sync speed of 24 megabits per second (Mbit/s). Utilizing G.992.5 Annex M upstream sync speeds of 3.3 Mbit/s can be achieved. Technical information ADSL2+ extends the capability of basic ADSL by doubling the number of downstream channels. The data rates can be as high as 24 Mbit/s downstream and up to 1.4 Mbit/s upstream depending on the distance from the DSLAM to the customer's premises. ADSL2+ is capable of doubling the frequency band of typical ADSL connections from 1.1 MHz to 2.2 MHz. This doubles the downstream data rates of the previous ADSL2 standard (which was up to 12 Mbit/s), and like the previous standards will degrade from its peak bitrate after a certain distance. ADSL2+ also allows port bonding. This is where multiple port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
