| comp., MS | differencing virtual hard disk | disco rigido virtuale differenze (" A virtual hard disk that stores the changes or "differences" to an associated parent virtual hard disk for the purpose of keeping the parent intact. The differencing disk is a separate .vhd file that is associated with the .vhd file of the parent disk. Changes continue to accumulate in the differencing disk until it is merged to the parent disk.") |
| comp., MS | dynamically expanding virtual hard disk | disco rigido virtuale a espansione dinamica (A virtual hard disk that grows in size each time it is modified. This type of virtual hard disk starts as a 3 KB .vhd file and can grow as large as the maximum size specified when the file was created. The only way to reduce the file size is to zero out the deleted data and then compact the virtual hard disk) |
| comp., MS | Edit Virtual Hard Disk Wizard | Modifica guidata disco rigido virtuale (A wizard that is used by advanced users to perform specific operations on their existing virtual hard disks such as compacting their virtual hard disk, merging it, converting it to another type or expanding its size) |
| comp., MS | fixed-size virtual hard disk | disco rigido virtuale a dimensione fissa (A virtual hard disk with a fixed size that is determined and for which all space is allocated when the disk is created. The size of the disk does not change when data is added or deleted) |
| comp., MS | linked virtual hard disk | disco rigido virtuale collegato (A virtual hard disk that points to and uses an entire physical disk for the purpose of converting a data disk to a virtual hard disk. You cannot turn on a virtual machine if a linked disk is attached to the virtual machine) |
| comp., MS | New Virtual Hard Disk Wizard | Creazione guidata disco rigido virtuale (A wizard that is used by advanced users to create custom virtual hard disks for virtual machines. The purpose of the New Virtual Hard Disk Wizard is to gather the basic information from the user necessary to create a new virtual hard disk) |
| comp., MS | virtual disk | disco virtuale (A collection of one or more physical disks from a previously created storage pool) |
| comp., MS | Virtual Disk Service | Servizio dischi virtuali (A set of application programming interfaces (APIs) that provides a single interface for managing disks. VDS uses two sets of providers to manage storage devices. The built-in VDS software providers enable the management of disks and volumes at the operating system level. The VDS hardware providers enable the management of disk storage subsystems and are supplied by the hardware vendor) |
| comp., MS | virtual floppy disk | disco floppy virtuale (A file-based version of a physical floppy disk. A virtual floppy disk is stored as a file with a .vfd file name extension) |
| comp., MS | virtual hard disk | disco rigido virtuale (The storage medium for a virtual machine. It can reside on any storage topology that the host operating system can access, including external devices, storage area networks, and network-attached storage. The file format is .vhd) |
