A portion of the computer main memory can be set up as a RAM disk that serves as a storage device for a file system. File systems such as tmpfs can store files in virtual memory. A virtual file system provides access to files that are either computed on request, called virtual files (see procfs and sysfs), or are mapping into another, backing ...
Network-attached storage (NAS) is mass storage attached to a computer which another computer can access at file level over a local area network, a private wide area network, or in the case of online file storage, over the Internet. NAS is commonly associated with the NFS and CIFS/SMB protocols.
Many different types of storage exist, including magnetic, magneto-optical, optical, and semiconductor (solid-state) drives. Before any of them can be used for storage, the means by which information is read and written must be organized and knowledge of this must be available to the operating system. The organization is called a filesystem.
Electronic data storage requires electrical power to store and retrieve data. Data storage in a digital, machine-readable medium is sometimes called digital data. Computer data storage is one of the core functions of a general-purpose computer. Electronic documents can be stored in much less space than paper documents. [3]
Shared-disk file systems (also called shared-storage file systems, SAN file system, Clustered file system or even cluster file systems) are primarily used in a storage area network where all nodes directly access the block storage where the file system is located. This makes it possible for nodes to fail without affecting access to the file ...
A computer file is a resource for recording data on a computer storage device, primarily identified by its filename. Just as words can be written on paper, so too can data be written to a computer file. Files can be shared with and transferred between computers and mobile devices via removable media, networks, or the Internet.
In computer file systems, a cluster (sometimes also called allocation unit or block) is a unit of disk space allocation for files and directories.To reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors by default, but contiguous groups of sectors, called clusters.
It also has two folder like-items called "Default User" (an NTFS junction point to "Default" folder) and "All Users" (a NTFS symbolic link to "C:\ProgramData"). \Public: This folder serves as a buffer for users of a computer to share files. By default this folder is accessible to all users that can log on to the computer.
