::* Shared disk architecture, where each processing unit ( typically consisting of multiple processors ) has its own main memory, but all units share the other storage.

* Shared file access

Shared Source programs allow individuals and organizations to access Microsoft's source code for reference ( e. g. when developing complementary systems ), for review and auditing from a security perspective ( mostly wanted by some large corporations and governments ), and for development ( academic institutions, OEMs, individual developers ).

* Shared file access

You can also change the permissions on the Shared folder or any of the folders inside of a home folder to facilitate or limit access by users based on group membership.

Otherwise, disk access would be limited to low-level operations such as reading and writing disks at the sector-level.

Both hard disks and floppy disk drives require software to manage rapid access to block storage of sequential and other data.

The MSX-DOS kernel resided in ROM ( built-in on the disk controller ) so basic file access capacity was available even without the command interpreter, by using BASIC extended commands.

However, it was reasonably successful in the server market, as it was better suited to bandwidth-intensive tasks ( such as disk access and networking ).

Windows for Workgroups 3. 11 added 32-bit networking and 32-bit disk access.

It could therefore be dangerous to access a disk containing files created with CP / M Plus using LocoScript, since LocoScript could decide to delete anything in users 8 to 15.

Early MUMPS programmers would often store a structure of related information as a delimited string, parsing it after it was read in ; this saved disk access time and offered considerable speed advantages on some hardware.

While the actual numbers behind this definition were never firm, the concept allowed customers to share access to expensive resources like disk drives and printers, send e-mail, and access the Internet.

Reference counting is also used in disk operating systems and distributed systems, where full non-incremental tracing garbage collection is too time consuming because of the size of the object graph and slow access speed.

The property of not needing to access a reference count when a reference is copied is particularly helpful when the object's reference count is expensive to access, for example because it is in another process, on disk, or even across a network.

In computer science, sequential access means that a group of elements ( e. g. data in a memory array or a disk file or on magnetic tape data storage ) is accessed in a predetermined, ordered sequence.

A tape drive provides sequential access storage, unlike a disk drive, which provides random access storage.

Data are transferred between the application's buffer and the disk using DMA, which allows access to the full I / O bandwidth of the underlying disk devices.

To enable BASIC programmers to access the additional memory, a RAM disk was created where files could be stored in the additional 80 kB of RAM.

* Random disk or memory access

In computing, a file server is a computer attached to a network that has the primary purpose of providing a location for shared disk access, i. e. shared storage of computer files ( such as documents, sound files, photographs, movies, images, databases, etc.

These patterns were impossible to detect using standard DOS or BIOS calls, so direct access to the disk controller hardware was necessary for the protection to work.

Bit-level addressing suits bit-serial applications ( such as hard disk emulation ), which access only 1 bit at a time.

However the storage is attached, the drives themselves are usually configured as a Redundant Array of Inexpensive ( or Independent ) Discs RAID, which may be configured to provide appropriate combination of faster disk access or protection against the failure of one ( or even two ) discs in the physical RAID array.

; LOCK: Enables external programs to perform low-level disk access to a volume.

; UNLOCK: Disables low-level disk access.
