Root Directory
In a Computing, computer file system, and primarily used in the Unix and Unix-like operating systems, the root directory is the first or top-most Directory (computing), directory in a hierarchy. It can be likened to the trunk of a Tree (data structure), tree, as the starting point where all branches originate from. The root file system is the file system contained on the same Disk Partition Recovery, disk partition on which the root directory is located; it is the filesystem on top of which all other file systems are Mount (computing), mounted as the system boots up. Unix-like systems Unix abstracts the nature of this tree hierarchy entirely and in Unix and Unix-like systems the root directory is denoted by the / (slash) sign. Though the root directory is conventionally referred to as /, the directory entry itself has no name its path is the "empty" part before the initial directory separator character (/). All file system entries, including mounted file systems are "branches" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenIndiana 2015 Console LS
OpenIndiana is a free and open-source Illumos#Distributions, illumos distribution compatible with SPARC and x86-64 based computers. The project began in 2010, Fork (software development), forked from OpenSolaris after OpenSolaris was discontinued by Oracle Corporation, and is hence descended from UNIX System V#SVR4, UNIX System V Release 4. Created by a development team led by Alasdair Lumsden, the OpenIndiana project is now stewarded by the illumos Foundation, which develops and maintains the illumos operating system. The project aims to make OpenIndiana "the ''de facto'' OpenSolaris distribution installed on production servers where security and bug fixes are provided free of charge." History OpenIndiana takes its name from Project Indiana, the internal codename for OpenSolaris at Sun Microsystems before Acquisition of Sun Microsystems by Oracle Corporation, Oracle’s acquisition of Sun in 2010. Origins Project Indiana was originally conceived by Sun Microsystems, to cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parent Directory
In computing, a directory is a file system cataloging structure that contains references to other computer files, and possibly other directories. On many computers, directories are known as folders or drawers, analogous to a workbench or the traditional office filing cabinet. The name derives from books like a telephone directory that lists the phone numbers of all the people living in a certain area. Files are organized by storing related files in the same directory. In a hierarchical file system (that is, one in which files and directories are organized in a manner that resembles a tree), a directory contained inside another directory is called a subdirectory. The terms parent and child are often used to describe the relationship between a subdirectory and the directory in which it is cataloged, the latter being the parent. The top-most directory in such a filesystem, which does not have a parent of its own, is called the root directory. The freedesktop.org media type for ...

Filesystem Hierarchy Standard
The Filesystem Hierarchy Standard (FHS) is a reference describing the conventions used for the layout of Unix-like systems. It has been made popular by its use in Linux distributions, but it is used by other Unix-like systems as well. It is maintained by the Linux Foundation. The latest version is 3.0, released on 3 June 2015. Directory structure In the FHS, all files and directories appear under the root directory /, even if they are stored on different physical or virtual devices. Some of these directories only exist in a particular system if certain subsystems, such as the X Window System, are installed. Most of these directories exist in all Unix-like operating systems and are generally used in much the same way; however, the descriptions here are those used specifically for the FHS and are not considered authoritative for platforms other than Linux. FHS compliance Most Linux distributions follow the Filesystem Hierarchy Standard and declare it their own policy to mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domain Name
In the Internet, a domain name is a string that identifies a realm of administrative autonomy, authority, or control. Domain names are often used to identify services provided through the Internet, such as websites, email services, and more. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain or an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, or a server computer. Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name. Domain names are organized in subordinate levels ('' subdomains'') of the DNS root domain, which is nameless. The first-level set of domain names are the ''top-level domains'' (TLDs), including the ''generic top-level domains'' (gTLDs), such as the prominent domains com, info, net, edu, and org, and the ''country code t ...

Website
A website (also written as a web site) is any web page whose content is identified by a common domain name and is published on at least one web server. Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment, or social media. Hyperlinking between web pages guides the navigation of the site, which often starts with a home page. The most-visited sites are Google, YouTube, and Facebook. All publicly-accessible websites collectively constitute the World Wide Web. There are also private websites that can only be accessed on a private network, such as a company's internal website for its employees. Users can access websites on a range of devices, including desktops, laptops, tablets, and smartphones. The app used on these devices is called a web browser. Background The World Wide Web (WWW) was created in 1989 by the British CERN computer scientist Tim Berners-Lee. On 30 April 1993, CERN announced that the ...

Home Page
A home page (or homepage) is the main web page of a website. Usually, the home page is located at the Root directory, root of the website's Domain name, domain or subdomain. For example, if the domain is example.com, the home page is likely located at the URL www.example.com/. The term may also refer to the start page shown in a web browser when the application software, application first opens. Function A home page is the main web page that a visitor will view when they navigate to a website via a search engine, and it may also function as a landing page to attract visitors. In some cases, the home page is a Webserver directory index, site directory, particularly when a website has multiple home pages. Good home Web design, page design is usually a high priority for a website; for example, a news website may curate headlines and first paragraphs of top stories, with hyperlink, links to full articles. According to ''Homepage Usability'', the home page is the "most importan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mac (computer)
Mac is a brand of personal computers designed and marketed by Apple Inc., Apple since 1984. The name is short for Macintosh (its official name until 1999), a reference to the McIntosh (apple), McIntosh apple. The current product lineup includes the MacBook Air and MacBook Pro laptops, and the iMac, Mac Mini, Mac Studio, and Mac Pro desktops. Macs are currently sold with Apple's UNIX-based macOS operating system, which is Proprietary software, not licensed to other manufacturers and exclusively Pre-installed software, bundled with Mac computers.

Superuser
In computing, the superuser is a special user account used for system administration. Depending on the operating system (OS), the actual name of this account might be root, administrator, admin or supervisor. In some cases, the actual name of the account is not the determining factor; on Unix-like systems, for example, the user with a user identifier (UID) of zero is the superuser .e., uid=0 regardless of the name of that account; and in systems which implement a r model, any user with the role of superuser (or its synonyms) can carry out all actions of the superuser account. The principle of least privilege recommends that most users and applications run under an ordinary account to perform their work, as a superuser account is capable of making unrestricted, potentially adverse, system-wide changes. Unix and Unix-like In Unix-like computer OSes (such as Linux), ''root'' is the conventional name of the user who has all rights or permissions (to all files and programs) in all mod ...

Home Directory
A home directory is a directory (file systems), file system directory on a multi-user operating system containing computer file, files for a given user (computing), user of the system. The specifics of the home directory (such as its name and location) are defined by the operating system involved; for example, Linux / BSD (Filesystem Hierarchy Standard, FHS) systems use /home/ or /usr/home/, macOS uses /Users/, and Microsoft Windows, Windows systems since Windows Vista use \Users\. Description A user's home directory is intended to contain that user's files; including text documents, music, pictures, videos, etc. It may also include their configuration files of preferred settings for any software they have used there and might have tailored to their liking: web browser bookmark (digital), bookmarks, favorite desktop metaphor, desktop wallpaper (computing), wallpaper and theme (computing), themes, stored passwords to any external services accessed via a given software, etc. The use ...

OS/2
OS/2 is a Proprietary software, proprietary computer operating system for x86 and PowerPC based personal computers. It was created and initially developed jointly by IBM and Microsoft, under the leadership of IBM software designer Ed Iacobucci, intended as a replacement for DOS. The first version was released in 1987. A feud between the two companies beginning in 1990 led to Microsoft’s leaving development solely to IBM, which continued development on its own. OS/2 Warp 4 in 1996 was the last major upgrade, after which IBM slowly halted the product as it failed to compete against Microsoft's Microsoft Windows, Windows; updated versions of OS/2 were released by IBM until 2001. The name stands for "Operating System/2", because it was introduced as part of the same generation change release as IBM's "IBM Personal System/2, Personal System/2 (PS/2)" line of second-generation PCs. OS/2 was intended as a protected mode, protected-mode successor of IBM PC DOS, PC DOS targeting t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
