Access-control list

In computer security, an access-control list (ACL) is a list of permissions associated with a system resource (object or facility).

See Ext3cow and Access-control list

Byte

The byte is a unit of digital information that most commonly consists of eight bits.

See Ext3cow and Byte

Comparison of file systems

The following tables compare general and technical information for a number of file systems.

See Ext3cow and Comparison of file systems

Copy-on-write

Copy-on-write (COW), sometimes referred to as implicit sharing or shadowing, is a resource-management technique used in computer programming to efficiently implement a "duplicate" or "copy" operation on modifiable resources (most commonly memory pages, storage sectors, files, and data structures).

See Ext3cow and Copy-on-write

Ext2

ext2, or second extended file system, is a file system for the Linux kernel. Ext3cow and ext2 are disk file systems and file systems supported by the Linux kernel.

See Ext3cow and Ext2

Ext3

ext3, or third extended filesystem, is a journaled file system that is commonly used by the Linux kernel. Ext3cow and ext3 are disk file systems and file systems supported by the Linux kernel.

See Ext3cow and Ext3

GUID Partition Table

The GUID Partition Table (GPT) is a standard for the layout of partition tables of a physical computer storage device, such as a hard disk drive or solid-state drive, using universally unique identifiers (UUIDs), which are also known as globally unique identifiers (GUIDs).

See Ext3cow and GUID Partition Table

Health Insurance Portability and Accountability Act

The Health Insurance Portability and Accountability Act of 1996 (HIPAA or the Kennedy–Kassebaum Act) is a United States Act of Congress enacted by the 104th United States Congress and signed into law by President Bill Clinton on August 21, 1996.

See Ext3cow and Health Insurance Portability and Accountability Act

HTree

An HTree is a specialized tree data structure for directory indexing, similar to a B-tree. Ext3cow and HTree are disk file systems.

See Ext3cow and HTree

Linux

Linux is both an open-source Unix-like kernel and a generic name for a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds.

See Ext3cow and Linux

List of file systems

The following lists identify, characterize, and link to more thorough information on file systems.

See Ext3cow and List of file systems

Master boot record

A master boot record (MBR) is a type of boot sector in the first few blocks of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond.

See Ext3cow and Master boot record

Microsoft basic data partition

In Microsoft operating systems, when using basic disk partitioned with GUID Partition Table (GPT) layout, a basic data partition (BDP) is any partition identified with Globally Unique Identifier (GUID) of. Ext3cow and Microsoft basic data partition are disk file systems.

See Ext3cow and Microsoft basic data partition

Next3

Next3 is a journaling file system for Linux based on ext3 which adds snapshots support, yet retains compatibility to the ext3 on-disk format. Ext3cow and Next3 are disk file systems and file systems supported by the Linux kernel.

See Ext3cow and Next3

Open source

Open source is source code that is made freely available for possible modification and redistribution.

See Ext3cow and Open source

Rémy Card

Rémy Card is a French software developer who is credited as one of the primary developers of the Extended file system (ext) and Second Extended file system (ext2) for Linux.

See Ext3cow and Rémy Card

Sarbanes–Oxley Act

The Sarbanes–Oxley Act of 2002 is a United States federal law that mandates certain practices in financial record keeping and reporting for corporations.

See Ext3cow and Sarbanes–Oxley Act

Stephen Tweedie

Stephen C. Tweedie is a Scottish software developer who is known for his work on the Linux kernel, in particular his work on filesystems.

See Ext3cow and Stephen Tweedie

Theodore Ts'o

Theodore Yue Tak Ts'o (born 1968) is an American software engineer mainly known for his contributions to the Linux kernel, in particular his contributions to file systems.

See Ext3cow and Theodore Ts'o

Versioning file system

A versioning file system is any computer file system which allows a computer file to exist in several versions at the same time.
