Virtual Disk And Virtual Drive
Virtual disk and virtual drive are software components that emulate an actual disk storage device. Virtual disks and virtual drives are common components of virtual machines in hardware virtualization, but they are also widely used for various purposes unrelated to virtualization, such as for the creation of logical disks,software development, testing environments, and data management. They offer flexibility, ease of management, and the ability to simulate different storage environments without needing physical hardware. Operation A virtual drive is a software component that emulates an actual disk drive, such as an optical disc drive, a floppy disk drive, or a hard disk drive. To other programs, a virtual drive looks and behaves like an actual physical device. A virtual disk may be in any of the following forms: * Disk image, a computer file that contains the exact data structure of an actual storage device * Logical disk (also known as vdisk), an array of two or more actual d ...

Veritas Logo Neu
In Roman mythology, Veritas (), meaning Truth, is the Goddess of Truth, a daughter of Saturn (called Cronus by the Greeks, the Titan of Time, perhaps first by Plutarch) and the mother of Virtus. She is also sometimes considered the daughter of Jupiter (called Zeus by the Greeks), or a creation of Prometheus. The elusive goddess is said to have hidden in the bottom of a holy well. She is depicted both as a virgin dressed in white and as the "naked truth" (''nuda veritas'') holding a hand mirror. The eqivalent Greek goddess is Aletheia (Ancient Greek: ). ''Veritas'' was the Roman virtue of truthfulness, which was considered one of the main virtues any good Roman should possess. The German philosopher Martin Heidegger argues that the truth represented by ''aletheia'' (which essentially means "unconcealment") is different from that represented by ''veritas'', which is linked to a Roman understanding of rightness and finally to a Nietzschean sense of justice and a will to power.

RAID
RAID (; redundant array of inexpensive disks or redundant array of independent disks) is a data storage virtualization technology that combines multiple physical Computer data storage, data storage components into one or more logical units for the purposes of data redundancy, performance improvement, or both. This is in contrast to the previous concept of highly reliable mainframe disk drives known as ''single large expensive disk'' (''SLED''). Data is distributed across the drives in one of several ways, referred to as RAID levels, depending on the required level of redundancy (engineering), redundancy and performance. The different schemes, or data distribution layouts, are named by the word "RAID" followed by a number, for example RAID 0 or RAID 1. Each scheme, or RAID level, provides a different balance among the key goals: reliability engineering, reliability, availability, computer performance, performance, and computer data storage#Capacity, capacity. RAID levels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application Checkpointing
Checkpointing is a technique that provides fault tolerance for computing systems. It involves saving a Snapshot (computer storage), snapshot of an application software, application's state, so that it can restart from that point in case of failure. This is particularly important for long-running applications that are executed in failure-prone computing systems. Checkpointing in distributed systems In the distributed computing environment, checkpointing is a technique that helps tolerate failures that would otherwise force a long-running application to restart from the beginning. The most basic way to implement checkpointing is to stop the application, copy all the required data from the memory to reliable storage (e.g., parallel file system), then continue with execution. In the case of failure, when the application restarts, it does not need to start from scratch. Rather, it will read the latest state ("the checkpoint") from the stable storage and execute from that point. While ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NS32000
The NS32000, sometimes known as the 32k, is a series of microprocessors produced by National Semiconductor. Design work began around 1980 and it was announced at the International Solid-State Circuits Conference in April 1981. The first member of the family came to market in 1982, briefly known as the 16032 before being renamed as the 32016. It was the first general-purpose microprocessor on the market that used 32-bit data internally: the Motorola 68000 had 32-bit registers and instructions to perform 32-bit arithmetic, but used a 16-bit ALU for arithmetic operations on data, and thus took twice as long as the 32016 to perform those arithmetic operations. However, the 32016 contained many bugs and often could not be run at its rated speed. These problems, and the presence of the otherwise similar 68000 which had been available since 1980, led to little use in the market despite considerable early interest. Several improved versions followed, including 1985's 32032 which was ess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channel I/O
In computing, channel I/O is a high-performance input/output (I/O) architecture that is implemented in various forms on a number of computer architectures, especially on mainframe computers. In the past, channels were generally implemented with custom devices, variously named channel, I/O processor, I/O controller, I/O synchronizer, or '' DMA controller''. Overview Many I/O tasks can be complex and require logic to be applied to the data to convert formats and other similar duties. In these situations, the simplest solution is to ask the CPU to handle the logic, but because I/O devices are relatively slow, a CPU could waste time waiting for the data from the device. This situation is called 'I/O bound'. Channel architecture avoids this problem by processing some or all of the I/O task without the aid of the CPU by offloading the work to dedicated logic. Channels are logically self-contained, with sufficient logic and working storage to handle I/O tasks. Some are powerful or fle ...

Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

Fault Tolerance
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 ...

Private Equity Firm
A private equity firm or private equity company (often described as a financial sponsor) is an investment management company that provides financial backing and makes investments in the private equity of a Startup company, startup or of an existing operating company with the end goal to make a profit on its investments. The target companies are generally privately owned entities (not publicly listed), but on rare occasions a private equity firm may purchase the majority of a publicly listed company and delist the firm after the purchase. To complete its investments, a private equity firm will raise funds from large institutional investors, family offices and others pools of Financial capital, capital (e.g. other private-equity funds) which supply the Ownership equity, equity. The money raised, often pooled into a fund, will be invested in accordance with one or more specific investment strategies including leveraged buyout, venture capital, and growth capital.
