What is a page map table?
In operating systems that use virtual memory, every process is given the impression that it is working with large, contiguous sections of memory. In reality, each process' memory may be dispersed across different areas of physical memory, or may have been paged out to a backup storage (typically the hard disk). When a process requests access to its memory, it is the responsibility of the operating system to map the virtual address provided by the process to the physical address where that memory is stored. The page table is where the operating system stores its mappings of virtual addresses to physical addresses.
What is space on computers storage device that simulates additional RAM?
It might be called "reserved virtual memory space" or "virtual memory file", depending on the operating system.
What is the process of deploying and maintaining multiple instances of an operating system on a single computer?
A Virtual Machine.
When an operating system uses secondary storage to store programs in RAM during execution of those programs is called?
virtual memory
When was Virtual Operating Room created?
Virtual Operating Room was created in 2007.
What role does a hypervisor play in managing virtual machines within an operating system environment?
A hypervisor is a software that creates and manages virtual machines within an operating system. It acts as a mediator between the physical hardware and the virtual machines, allowing multiple operating systems to run on a single physical machine. The hypervisor allocates resources, such as CPU, memory, and storage, to each virtual machine, ensuring they operate efficiently and securely.
What is name for memory is a concept in which the operating system allocates a portion of a storage medium to function as additional RAM?
It is commonly called "virtual memory".
What is the temporary storage unit on a computer?
Programmers often think of a computer as having only one temporary storage area, the random access memory (RAM). People using a computer often use a temporary storage location called the "clipboard". See "The what is a temporary holding area in your PC's memory that holds information you want to cut or move from its current location?" for details. The people who write operating systems and the computer architects that design computer systems and CPUs often use many different temporary storage areas, each one with a different name. Many of these temporary storage areas are stored in chips of silicon -- see the "What is temporary storage on chips called?" for details. Other temporary storage areas are stored on the hard drive -- such as the web page cache, the hibernation file, and the virtual memory swap file.
What is the process of physical to virtual?
Physical-to-Virtual, also known as "P2V", describes the process of decoupling and migrating a physical server's operating system, applications, and data from a physical server to a virtual machine guest hosted on a virtualized platform.
How does client virtualization work?
Virtualization works through the creation of a 'virtual' rather than 'actual' version of an operating system, hardware, storage or network device.
What are virtual devices in operating system?
virtual devices in os
What is the motto of Virtual Operating Room?
Virtual Operating Room's motto is 'Unique Solutions in an Ever-Changing World'.
