Some models supported separate instruction and data spaces for an effective virtual address size of 128 kB within a physical address size of up to 4 MB.

Multiple hostnames may correspond to a single IP address: combined with virtual hosting, this allows a single machine to serve many web sites.

The program counter is a 64-bit register which contains a longword-aligned virtual byte address, that is, the low two bits of the program counter are always zero.

The Alpha has a 64-bit linear virtual address space with no memory segmentation.

Implementations can implement a smaller virtual address space with a minimum size of 43 bits.

Although the unused bits were not implemented in hardware such as TLBs, the architecture required implementations to check if they are zero to ensure software compatibility with implementations that implemented a larger or the full virtual address space.

Microsoft had a double gain from its release: first, it made it impossible for consumers to run Windows 95 on a cheaper, non-Microsoft DOS ; secondly, although traces of DOS were never completely removed from the system and MS DOS 7 would be loaded briefly as a part of the booting process, Windows 95 applications ran solely in 386 enhanced mode, with a flat 32-bit address space and virtual memory.

These features make it possible for Win32 applications to address up to 2 gigabytes of virtual RAM ( with another 2 GB reserved for the operating system ), and in theory prevented them from inadvertently corrupting the memory space of other Win32 applications.

System / 370 introduced virtual memory capabilities in all models other than the very first System / 370 models ; the OS / VS1 variant of OS / 360 MFT, the OS / VS2 ( SVS ) variant of OS / 360 MVT, and the DOS / VS variant of DOS / 360 were introduced to use the virtual memory capabilities, followed by MVS, which, unlike the earlier virtual-memory operating systems, ran separate programs in separate address spaces, rather than running all programs in a single virtual address space.

This pass is usually omitted on hardware offering virtual memory — every program is put into its own address space, so there is no conflict even if all programs load at the same base address.

It can perform up to 8 times as fast as a DEC KL-10, and it also supports more physical memory, a larger virtual address space, and more modern input / output devices.

In the early 1970s IBM sought to mitigate these difficulties by introducing virtual memory ( which IBM called " virtual storage "), which allowed programs to request address spaces larger than physical memory.

The original implementations had a single virtual address space, shared by all jobs.

OS / VS1 was OS / 360 MFT within a single virtual address space ; OS / VS2 SVS was OS / 360 MVT within a single virtual address space.

In an indirect-threaded virtual machine, the one given here, the operations are:

This statement illustrates the difficulty of trying to distinguish between " real " and " virtual " particles, because, in mathematical terms, they are the same objects and it is only our definition of " reality " that is weak here.

In the 1990s, Pickover created virtual caverns from extremely simple numerical simulations that reminded him of the Lechuguilla Cave, pictured here.

In practical terms, Java SE consists of a virtual machine, which must be used to run Java programs, together with a set of libraries ( or " packages ") needed to allow the use of file systems, networks, graphical interfaces, and so on, from within those programs.

In the real as well as in the virtual world, Ars Electronica consists of several parts:

It consists of 101 base sites which are interconnected with other GRN networks around Australia allowing virtual communication with users either within the same state or across the country.

A constant-field Maxwell coil set consists of three coils oriented on the surface of a virtual sphere.

It consists of three columns: in the first column state names are used, in the second the virtual conditions built out of input names using the positive logic algebra are placed and in the third column the output names appear:

A swiki installation consists of the Virtual Machine ( VM ) file ( usually squeak. exe ), an image file ( usually squeak. image ), and a set of files and folders with templates and the virtual wikis.

It currently consists of five major campuses throughout south-central Pennsylvania, as well as several off-site centers, and a virtual campus, that provides online distance education courses.

A virtual network is a computer network that consists, at least in part, of virtual network links.

The Workstation software consists of a virtual machine suite for Intel x86-compatible computers ( running Microsoft Windows or Linux ) ( for Mac version, see Parallels Desktop for Mac ) which allows the simultaneous creation and execution of multiple x86 virtual computers.

CIHR consists of 13 " virtual " institutes, each headed by a Scientific Director and assisted by an Institute Advisory Board.

This investigative team consists of Kenzo Uji, an infomesh expert (' infomesh ' being an in-game term relating to human-computer virtual interface ) who describes himself as a " techno-zen hippy ;" Martin Karne, the security escort of the team who volunteered for the mission ; and Diane Matlock, a scientist who has friends in Vita 1.

If there are multiple page or segment tables, there are multiple virtual address spaces and concurrent applications with separate page tables redirect to different real addresses.

However, a virtual circuit is possible since TCP includes segment numbering and reordering on the receiver side to prevent out-of-order delivery.

Addressing was modified to use an 18-bit segment in addition to the 18-bit address, dramatically increasing the theoretical memory size and making virtual memory much easier to support.

Such systems set all segment registers to point to a segment descriptor with offset = 0 and limit = 2 < sup > 32 </ sup >, giving an application full access to a 32-bit flat virtual address space through any segment register.

If the paging unit is enabled, addresses in a segment are now virtual addresses, rather than physical addresses as they were on the 80286.

That is, the segment starting address, the offset, and the final 32-bit address the segmentation unit derives by adding the two are all virtual ( or logical ) addresses when the paging unit is enabled.

Sharing of virtual address space and inter-context communications could be provided by writing the same values in to the segment or page maps of different contexts.

The segment register acts as an index into a table, which provides an offset to be added to the virtual address.

The VMM works with virtual devices ( loadable kernel modules, which consist mostly of 32-bit ring 0 or kernel mode code, but may include other types of code, such as a 16-bit real mode initialisation segment ) to allow those virtual devices to intercept interrupts and faults to control the access that an application has to hardware devices and installed software.

Another example in the same computer family was the 16-bit protected mode of the 80286 processor, which, though supporting only 16 MiB of physical memory, could access up to 1 GiB of virtual memory, but the combination of 16-bit address and segment registers made accessing more than 64 KiB in one data structure cumbersome.

PaX randomly offsets the base of the stack in increments of 16 bytes, combining random placement of the actual virtual memory segment with a sub-page stack gap.

All physical routers acting as a virtual router must be in the same LAN segment.

* Memory-mapped file, a segment of virtual memory which has been assigned a direct byte-for-byte correlation with some portion of a file or file-like resource

A data segment is a portion of virtual address space of a program, which contains the global variables and static variables that are initialized by the programmer.

Layer 3, or VPRN ( virtual private routed network ), utilizes layer 3 VRF ( VPN / virtual routing and forwarding ) to segment routing tables for each “ customer ” utilizing the service.
