VM (operating System)
VM (often: VM/CMS) is a family of IBM virtual machine operating systems used on IBM mainframes System/370, System/390, zSeries, System z and compatible systems, including the Hercules (emulator), Hercules emulator for personal computers. Design The heart of the VM architecture is the ''Control Program'' or hypervisor abbreviated CP, VM-CP and sometimes, ambiguously, VM. It runs on the physical hardware, and creates the virtual machine environment. VM-CP provides full virtualization of the physical machine – including all I/O and other privileged operations. It performs the system's resource-sharing, including device management, dispatching, virtual storage management, and other traditional operating system tasks. Each VM user is provided with a separate virtual machine having its own address space, virtual devices, etc., and which is capable of running any software that could be run on a stand-alone machine. A given VM mainframe typically runs hundreds or thousands of virt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Active United States Marine Corps Aircraft Squadrons
This is a list of all of the active Squadron (aviation), squadrons that exist in the United States Marine Corps, sorted by type. Most squadrons have changed names and designations many times over the years, so they are listed by their current designation. :''To see United States Marine Corps Aviation, Marine Aviation units sorted by command hierarchy, see Aviation combat element#Hierarchy of Marine Aviation units, aviation combat element.'' Squadron designations The basic tactical and administrative unit of United States Marine Corps aviation is the squadron. Fixed-wing aircraft squadrons (heavier than air) and tiltrotor squadrons are denoted by the letter "V", which comes from the Spanish verb "volar" (to fly). Rotorcraft, Rotary wing (helicopter) squadrons use "H." Marine squadrons are always noted by the second letter "M." Squadron numbering is not linear as some were numbered in ascending order and others took numbers from the wing or the ship to which they were assigned. ...

Vasculogenic Mimicry
Vasculogenic mimicry (VM) is a strategy used by tumors to ensure sufficient blood supply is brought to its cells through establishing new tumor vascularization. This process is similar to tumor angiogenesis; on the other hand vascular mimicry is unique in that this process occurs independent of endothelial cells. Vasculature is instead developed ''De novo mutation, de novo'' by cancer cells, which under stress conditions such as Hypoxia (medical), hypoxia, express similar properties to stem cells, capable of differentiating to mimic the function of endothelial cells and form vasculature-like structures. The ability of tumors to develop and harness nearby vasculature is considered one of the hallmarks of cancer disease development and is thought to be closely linked to tumor invasion and metastasis. Vascular mimicry has been observed predominantly in aggressive and metastatic cancers and has been associated with negative tumor characteristics such as increased metastasis, increased ti ...

VM Motori
VM Motori S.p.A. is an Italian diesel engine manufacturing company which is wholly owned by Stellantis. VM headquarters and main production facilities are located in Cento, in Emilia-Romagna, Italy. History VM Motori was founded by two entrepreneurs, Claudio Vancini and Ugo Martelli (hence the ''"VM"'') in 1947. VM merged with ''Stabilimenti Meccanici Triestini'' in Trieste in 1971, then ''Finmeccanica'' took a majority stake in the combined company. The company was referred to as "Finmeccanica VM" for many years. In 1989, Finmeccanica restructured, selling its stake in VM Motori to company managers and Midland Montague in a leveraged buyout, leaving the company with its single Cento plant. Detroit Diesel, Detroit Diesel Corporation (DDC) bought VM Motori in 1995. In 2000, Detroit Diesel, DDC was purchased by DaimlerChrysler AG. In 2003, Penske Corporation purchased a 51% stake in VM Motori; in 2007, Penske bought the remaining 49% from Detroit Diesel, Detroit Diesel Corpor ...

Virtual Machine
In computing, a virtual machine (VM) is the virtualization or emulator, emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two. Virtual machines differ and are organized by their function, shown here: * ''System virtual machines'' (also called full virtualization VMs, or SysVMs) provide a substitute for a real machine. They provide the functionality needed to execute entire operating systems. A hypervisor uses native code, native execution to share and manage hardware, allowing for multiple environments that are isolated from one another yet exist on the same physical machine. Modern hypervisors use hardware-assisted virtualization, with virtualization-specific hardware features on the host CPUs providing assistance to hypervisors. * ''Process virtual machines'' are designed to execute computer programs ...

Voicemail
A voicemail system (also known as voice message or voice bank) is a computer-based system that allows callers to leave a recorded message when the recipient has been unable (or unwilling) to answer the phone. Calls may be directed to voicemail manually or automatically. The caller is prompted to leave a message that the recipient can retrieve at a later time. Voicemail can be used for personal calls, but more complex systems exist for companies and services to handle the volume of customer requests. The term is also used more broadly to denote ''any'' system of conveying stored telecommunications voice messages, including using older technology like answering machines. Features Voicemail systems are designed to convey a caller's recorded audio message to a recipient. To do so they contain a user interface to select, play, and manage messages; a delivery method to either play or otherwise deliver the message; and a notification ability to inform the user of a waiting message ...

Virtual Memory
In computing, virtual memory, or virtual storage, is a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" which "creates the illusion to users of a very large (main) memory". The computer's operating system, using a combination of hardware and software, maps memory addresses used by a program, called '' virtual addresses'', into ''physical addresses'' in computer memory. Main storage, as seen by a process or task, appears as a contiguous address space or collection of contiguous segments. The operating system manages virtual address spaces and the assignment of real memory to virtual memory. Address translation hardware in the CPU, often referred to as a memory management unit (MMU), automatically translates virtual addresses to physical addresses. Software within the operating system may extend these capabilities, utilizing, e.g., disk storage, to provide a virtual address space ...

VM (nerve Agent)
VM (Edemo) is a "V-series" nerve agent closely related to the better-known VX nerve agent. Like most of the agents in the V-series (with the exception of VX), VM has not been extensively studied outside of military science. Little is known about this chemical compound other than its chemical formula. It is commonly theorized that the so-called "second-generation" V series agents came from a Cold War era Russian chemical weapons development program. They may have been developed sometime between 1950 and 1990. They have similar lethal dose levels to VX (between 10 and 50 mg) and have similar symptoms and method of action to other nerve agents that act on cholinesterase. The treatment remains the same, but the window for effectively treating second generation V series seizures is shorter. In addition to the standard seizures, some of the second generation V series agents are known to cause coma A coma is a deep state of prolonged unconsciousness in which a person cannot ...

Virgin Mary
Mary was a first-century Jewish woman of Nazareth, the wife of Saint Joseph, Joseph and the mother of Jesus. She is an important figure of Christianity, venerated under titles of Mary, mother of Jesus, various titles such as Perpetual virginity of Mary, virgin or Queen of Heaven, queen, many of them mentioned in the Litany of Loreto. The Eastern Orthodox Church, Eastern and Oriental Orthodox, Catholic, Anglican, Methodist, Reformed Christianity, Reformed, Baptist, and Lutheran churches believe that Mary, as mother of Jesus, is the Theotokos, Mother of God. The Church of the East historically regarded her as Christotokos, a term still used in Assyrian Church of the East liturgy. Other Protestant views on Mary vary, with some holding her to have lesser status. She has the Mary in Islam, highest position in Islam among all women and is mentioned numerous times in the Quran, including in a chapter Maryam (surah), named after her.Jestice, Phyllis G.
