Subsidiary
A subsidiary, subsidiary company, or daughter company is a company (law), company completely or partially owned or controlled by another company, called the parent company or holding company, which has legal and financial control over the subsidiary company. Unlike regional branches or divisions, subsidiaries are considered to be distinct entities from their parent companies; they are required to follow the laws of where they are incorporated, and they maintain their own executive leadership. Two or more subsidiaries primarily controlled by same entity/group are considered to be sister companies of each other. Subsidiaries are a common feature of modern business, and most multinational corporations organize their operations via the creation and purchase of subsidiary companies. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, and Citigroup, which have subsidiaries involved in many different Industry (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NYSE Arca
NYSE Arca, previously known as ArcaEx, an abbreviation of Archipelago Exchange, is an exchange on which both stocks and options are traded. It was owned by Intercontinental Exchange. It merged with the New York Stock Exchange (NYSE) in 2006 and now operates as a subsidiary of the NYSE Group, Inc. It is headquartered in Chicago. Early reports indicated that NYSE Arca may have played a role in the 2010 flash crash. History In November 1994, Stuart Townsend and Gerald Putnam founded TerraNova Trading LLC, an electronic securities exchange, in Chicago. Its product, Archipelago, started accepting trading orders on January 20, 1997. In 2005, Archipelago Holdings, the owner of ArcaEx, bought the Pacific Exchange, after what had been a close working relationship since 2001. In 2006, ArcaEx merged with the NYSE and the name was changed to NYSE Arca. On August 22, 2013, the Arca system sent multiple sequences to Nasdaq which overloaded the Securities Information Processor (SIP) caus ...

Universal Storage Platform
Universal Storage Platform (USP) was the brand name for an Hitachi Data Systems line of computer data storage disk arrays circa 2004 to 2010. History The Hitachi Universal Storage Platform was first introduced in 2004. An entry-level enterprise and high-end midrange model, the Network Storage Controller was introduced in 2005. The Universal Storage Platform was one of the first disk arrays to virtualize other disk arrays in the appliance instead of in the network. The second generation Universal Storage Platform V replaced the original Universal Storage Platform in 2007 and the Universal Storage Platform VM replacing the original Network Storage Controller also in 2007. Architecture At the core of the Universal Storage Platform V and VM is a fully fault tolerant, high performance, non-blocking, silicon based switched architecture designed to provide the bandwidth needed to support infrastructure consolidation of enterprise file and block-based storage services on and beh ...

Symmetrix
The Symmetrix system was an EMC's enterprise storage array. It combined dozens of hard drives into a single virtual device that was then directly attached to a computer or I/O channel, or shared on a storage area network or a local area network. It was the flagship product of EMC in the 1990s and 2000s. History Symmetrix arrays, EMC's flagship product at that time, began shipping in 1990 as a storage array connected to an IBM mainframe via the block multiplexer channel. Newer generations of Symmetrix brought additional host connection protocols which include ESCON, SCSI, Fibre Channel-based storage area networks (SANs), FICON and iSCSI. The Symmetrix product was initially popular within the airline industry and with companies that were willing to deviate from the safety of IBM's 3390 disk subsystem and take a risk with the unproven Symmetrix array. This product is the main reason for the rapid growth of EMC in the 1990s, both in size and value, from a company valued hundr ...

Storage Array
A disk array is a disk storage system which contains multiple disk drives. It is differentiated from a disk enclosure, in that an array has cache memory and advanced functionality, like RAID, deduplication, encryption and virtualization. Components of a disk array include: * Disk array controllers * Cache in form of both volatile random-access memory and non-volatile flash memory. * Disk enclosures for both magnetic rotational hard disk drives and electronic solid-state drives. * Power supplies Typically a disk array provides increased availability, resiliency, and maintainability by using additional redundant components (controllers, power supplies, fans, etc.), often up to the point where all single points of failure (SPOFs) are eliminated from the design. Additionally, disk array components are often hot-swappable. Traditionally disk arrays were divided into categories: * Network attached storage (NAS) arrays * Storage area network (SAN) arrays: ** Modular SAN arrays ** Mo ...

Data Center
A data center is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. A large data center is an industrial-scale operation using as much electricity as a medium town. Estimated global data center electricity consumption in 2022 was 240–340 TWh, or roughly 1–1.3% of global electricity demand. This excludes energy used for cryptocurrency mining, which was estimated to be around 110 TWh in 2022, or another 0.4% of global electricity demand. The IEA projects that data center electric use could double between 2022 and 2026. High demand for electricity from data centers, incl ...

Social Networking
A social network is a social structure consisting of a set of social actors (such as individuals or organizations), networks of Dyad (sociology), dyadic ties, and other Social relation, social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities along with a variety of theories explaining the patterns observed in these structures. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine dynamics of networks. For instance, social network analysis has been used in studying the spread of misinformation on social media platforms or analyzing the influence of key figures in social networks. Social networks and the analysis of them is an inherently Interdisciplinarity, interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory. Georg Simmel authored early structural th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Computing
Cloud computing is "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand," according to International Organization for Standardization, ISO. Essential characteristics In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: * On-demand self-service: "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." * Broad network access: "Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations)." * Pooling (resource management), Resource pooling: " The provider' ...

Software As A Service
Software as a service (SaaS ) is a cloud computing service model where the provider offers use of application software to a client and manages all needed physical and software resources. SaaS is usually accessed via a web application. Unlike other software delivery models, it separates "the possession and ownership of software from its use". SaaS use began around 2000, and by 2023 was the main form of software application deployment. Unlike most self-hosted software products, only one version of the software exists and only one operating system and configuration is supported. SaaS products typically run on rented infrastructure as a service (IaaS) or platform as a service (PaaS) systems including hardware and sometimes operating systems and middleware, to accommodate rapid increases in usage while providing instant and continuous availability to customers. SaaS customers have the abstraction of limitless computing resources, while economy of scale drives down the cost. Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storage Virtualization
In computer science, storage virtualization is "the process of presenting a logical view of the physical storage resources to" a host computer system, "treating all storage media (hard disk, optical disk, tape, etc.) in the enterprise as a single pool of storage." A "storage system" is also known as a storage array, disk array, or ''filer''. Storage systems typically use special hardware and software along with disk drives in order to provide very fast and reliable storage for computing and data processing. Storage systems are complex, and may be thought of as a special purpose computer designed to provide storage capacity along with advanced data protection features. Disk drives are only one element within a storage system, along with hardware and special purpose embedded software within the system. Storage systems can provide either block accessed storage, or file accessed storage. Block access is typically delivered over Fibre Channel, iSCSI, SAS, FICON or other prot ...

Utility Computing
Utility computing, or computer utility, is a service provisioning model in which a service provider makes computing resources and infrastructure management available to the customer as needed, and charges them for specific usage rather than a flat rate. Like other types of on-demand computing (such as grid computing), the utility model seeks to maximize the efficient use of resources and/or minimize associated costs. Utility is the packaging of system resources, such as computation, storage and services, as a metered service. This model has the advantage of a low or no initial cost to acquire computer resources; instead, resources are essentially rented. This repackaging of computing services became the foundation of the shift to "on demand" computing, software as a service and cloud computing models that further propagated the idea of computing, application and network as a service. There was some initial skepticism about such a significant shift. However, the new model of com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
