NonStop (server Computers)
NonStop is a series of server computers introduced to market in 1976 by Tandem Computers Inc., beginning with the NonStop product line. It was followed by the Tandem Integrity NonStop line of lock-step fault-tolerant computers, now defunct (not to be confused with the later and much different Hewlett-Packard Integrity product line extension). The original NonStop product line is currently offered by Hewlett Packard Enterprise since Hewlett-Packard Company's split in 2015. Because NonStop systems are based on an integrated hardware/software stack, Tandem and later HPE also developed the NonStop OS operating system for them. NonStop systems are, to an extent, self-healing. To circumvent single points of failure, they are equipped with almost all redundant components. When a mainline component fails, the system automatically falls back to the backup. These systems can be used by banks, stock exchanges, payment applications, retail companies, energy and utility services, healt ...

Hewlett Packard Enterprise
The Hewlett Packard Enterprise Company (HPE) is an American multinational information technology company based in Spring, Texas. It is a business-focused organization which works in servers, storage, networking, containerization software and consulting and support. HPE was ranked No. 107 in the 2018 ''Fortune'' 500 list of the largest United States corporations by total revenue. HPE was founded on November 1, 2015, in Palo Alto, California, as part of the splitting of the Hewlett-Packard company. The split was structured so that the former Hewlett-Packard Company would change its name to HP Inc. and spin off Hewlett Packard Enterprise as a newly created company. HP Inc. retained the old HP's personal computer and printing business, as well as its stock-price history and original NYSE ticker symbol for Hewlett-Packard; Enterprise trades under its own ticker symbol: HPE. At the time of the spin-off, HPE's revenue was slightly less than that of HP Inc. The company relocated to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X86-64
x86-64 (also known as x64, x86_64, AMD64, and Intel 64) is a 64-bit extension of the x86 instruction set architecture, instruction set. It was announced in 1999 and first available in the AMD Opteron family in 2003. It introduces two new operating modes: 64-bit mode and compatibility mode, along with a new four-level paging mechanism. In 64-bit mode, x86-64 supports significantly larger amounts of virtual memory and physical memory compared to its 32-bit computing, 32-bit predecessors, allowing programs to utilize more memory for data storage. The architecture expands the number of general-purpose registers from 8 to 16, all fully general-purpose, and extends their width to 64 bits. Floating-point arithmetic is supported through mandatory SSE2 instructions in 64-bit mode. While the older x87 FPU and MMX registers are still available, they are generally superseded by a set of sixteen 128-bit Processor register, vector registers (XMM registers). Each of these vector registers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fault-tolerant
Fault tolerance is the ability of a system to maintain proper operation despite failures or faults in one or more of its components. This capability is essential for high-availability, mission-critical, or even life-critical systems. Fault tolerance specifically refers to a system's capability to handle faults without any degradation or downtime. In the event of an error, end-users remain unaware of any issues. Conversely, a system that experiences errors with some interruption in service or graceful degradation of performance is termed 'resilient'. In resilience, the system adapts to the error, maintaining service but acknowledging a certain impact on performance. Typically, fault tolerance describes computer systems, ensuring the overall system remains functional despite hardware or software issues. Non-computing examples include structures that retain their integrity despite damage from fatigue, corrosion or impact. History The first known fault-tolerant computer was S ...

TACL (programming Language)
TACL (Tandem Advanced Command Language) is the scripting programming language which acts as the shell in Tandem Computers/ NonStop computers. History Tandem computers were originally designed and sold by Tandem Computers, Inc., based in Cupertino, CA. These were the first commercially available parallel processing computers. Despite their ability to expand to large sizes using parallelism, later to be called clustering, they were in the category of "mini-computers". Tandem's strategy was the emerging concept of "continuous availability" for applications requiring near-total uptime, in which single points of failure were minimized through mirrored storage devices, controllers and software, and operating systems engineered specifically for fault tolerance (using the Guardian operating system, later NonStop Kernel or NSK, and later NonStop OS). In computing, a single point of failure refers to any scenario in which the failure of a single component, application or process could re ...

Transaction Application Language
Transaction Application Language or TAL (originally "Tandem Application Language") is a block-structured, procedural language optimized for use on Tandem (and later HP NonStop) hardware. TAL resembles a cross between C and Pascal. It was the original system programming language for the Tandem Computers CISC machines, which had no assembler. The design concept of TAL, an evolution of Hewlett-Packard's SPL, was intimately associated and optimized with a microprogrammed CISC instruction set. Each TAL statement could easily compile into a sequence of instructions that manipulated data on a transient floating register stack. The register stack itself floated at the crest of the program's memory allocation and call stack. The language itself has the appearance of ALGOL or Pascal, with BEGIN and END statements. However, its semantics are far more like C. It does not permit indefinite levels of procedure nesting, it does not pass complex structured arguments by value, and it does ...

COBOL
COBOL (; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. Many large financial institutions were developing new systems in the language as late as 2006, but most programming in COBOL today is purely to maintain existing applications. Programs are being moved to new platforms, rewritten in modern languages, or replaced with other software. COBOL was designed in 1959 by CODASYL and was partly based on the programming language FLOW-MATIC, designed by Grace Hopper. It was created as part of a U.S. Department of Defense effort to create a portable programming language for data pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages. Java gained popularity sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
