Clustered File System
A clustered file system is a file system which is shared by being simultaneously mounted on multiple servers. There are several approaches to clustering, most of which do not employ a clustered file system (only direct attached storage for each node). Clustered file systems can provide features like location-independent addressing and redundancy which improve reliability or reduce the complexity of the other parts of the cluster. Parallel file systems are a type of clustered file system that spread data across multiple storage nodes, usually for redundancy or performance. Shared-disk file system A shared-disk file system uses a storage area network (SAN) to allow multiple computers to gain direct disk access at the block level. Access control and translation from file-level operations that applications use to block-level operations used by the SAN must take place on the client node. The most common type of clustered file system, the shared-disk file system —by add ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intellectual Property
Intellectual property (IP) is a category of property that includes intangible creations of the human intellect. There are many types of intellectual property, and some countries recognize more than others. The best-known types are patents, copyrights, trademarks, and trade secrets. The modern concept of intellectual property developed in England in the 17th and 18th centuries. The term "intellectual property" began to be used in the 19th century, though it was not until the late 20th century that intellectual property became commonplace in the majority of the world's legal systems."property as a common descriptor of the field probably traces to the foundation of the World Intellectual Property Organization (WIPO) by the United Nations." in Mark A. Lemley''Property, Intellectual Property, and Free Riding'', Texas Law Review, 2005, Vol. 83:1031, page 1033, footnote 4. The main purpose of intellectual property law is to encourage the creation of a wide variety of intellectual goo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avnet
Avnet, Inc. is a distributor of electronic components headquartered in Phoenix, Arizona, named after Charles Avnet, who founded the company in 1921. After its start on Manhattan's Radio Row, the company became incorporated in 1955 and began trading on the New York Stock Exchange in 1961. On May 8, 2018, Avnet changed stock markets to Nasdaq, trading under the same ticker AVT. History 19201930 In 1921, Charles Avnet, a 33-year-old Russian-Jewish immigrant, began buying surplus radio parts and selling them to the public on the Radio Rows of United States port cities. As radio manufacturing grew, parts distribution took off. In the mid-1920s, when factory-made radios began to replace radio parts, he adjusted his distribution pipeline and began selling parts to manufacturers and dealers. In the mid-1920s, Avnet diversified by branching out into car radio kits and automobile assembly kits. During the Great Depression, he shifted the focus from retailing to wholesaling. 19301940 Du ...

Cloud Computing
Cloud computing is the on-demand availability of computer system resources, especially data storage ( cloud storage) and computing power, without direct active management by the user. Large clouds often have functions distributed over multiple locations, each of which is a data center. Cloud computing relies on sharing of resources to achieve coherence and typically uses a "pay as you go" model, which can help in reducing capital expenses but may also lead to unexpected operating expenses for users. Value proposition Advocates of public and hybrid clouds claim that cloud computing allows companies to avoid or minimize up-front IT infrastructure costs. Proponents also claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and that it enables IT teams to more rapidly adjust resources to meet fluctuating and unpredictable demand, providing burst computing capability: high computing p ...

Virtualization
In computing, virtualization or virtualisation (sometimes abbreviated v12n, a numeronym) is the act of creating a virtual (rather than actual) version of something at the same abstraction level, including virtual computer hardware platforms, storage devices, and computer network resources. Virtualization began in the 1960s, as a method of logically dividing the system resources provided by mainframe computers between different applications. An early and successful example is IBM CP/CMS. The control program CP provided each user with a simulated stand-alone System/360 computer. Since then, the meaning of the term has broadened. Hardware virtualization ''Hardware virtualization'' or ''platform virtualization'' refers to the creation of a virtual machine that acts like a real computer with an operating system. Software executed on these virtual machines is separated from the underlying hardware resources. For example, a computer that is running Arch Linux may host a virtual machi ...

Bus (computing)
In computer architecture, a bus (shortened form of the Latin '' omnibus'', and historically also called data highway or databus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols. Early computer buses were parallel electrical wires with multiple hardware connections, but the term is now used for any physical arrangement that provides the same logical function as a parallel electrical busbar. Modern computer buses can use both parallel and bit serial connections, and can be wired in either a multidrop (electrical parallel) or daisy chain topology, or connected by switched hubs, as in the case of Universal Serial Bus (USB). Background and nomenclature Computer systems generally consist of three main parts: * The central processing unit (CPU) that processes data, * The memory that holds the p ...

Crossbar Switch
In electronics and telecommunications, a crossbar switch (cross-point switch, matrix switch) is a collection of switches arranged in a matrix configuration. A crossbar switch has multiple input and output lines that form a crossed pattern of interconnecting lines between which a connection may be established by closing a switch located at each intersection, the elements of the matrix. Originally, a crossbar switch consisted literally of crossing metal bars that provided the input and output paths. Later implementations achieved the same switching topology in solid-state electronics. The crossbar switch is one of the principal telephone exchange architectures, together with a rotary switch, memory switch, and a crossover switch. General properties A crossbar switch is an assembly of individual switches between a set of inputs and a set of outputs. The switches are arranged in a matrix. If the crossbar switch has M inputs and N outputs, then a crossbar has a matrix with ''M'' × ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Data Systems
Electronic all cash BSN acc: 1311729000110205 Data Systems (EDS) was an American multinational information technology equipment and services company headquartered in Plano, Texas which was founded in 1962 by Ross Perot. The company was a subsidiary of General Motors from 1984 until it was spun off in 1996. EDS was acquired by Hewlett-Packard in 2008. History Electronic Data Systems (EDS) was founded in 1962 by H. Ross Perot, a graduate of the United States Naval Academy and a successful IBM salesman who first-hand observed how inefficiently IBM's customers typically were using their expensive systems. Somewhat to IBM's chagrin, since the company wanted to sell as many computers as possible, Perot made a fortune changing this. An early success was in matching the unused computer time at Southwestern Life Insurance Company with the computing needs of rapidly expanding Collins Radio, both located in Dallas, Texas. Perot knew the inside details of both companies. In its ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
