A directory is one of the first concepts anyone learning computers encounters aside from files. He or she soon learns that these files are all contained in a listing called the directory.
Who could forget the early DOS days when the command of choice was ?dir c:??
A directory contained inside another directory is called a subdirectory of that directory. Together, the directories form a hierarchy, or tree structure. Organization of file systems into such makes for a more organized hierarchy.
It allows the files to be grouped according to the owner's desire, and presents a more organized alternative to just having all the files dumped into one listing.
Microsoft Windows and the Mac OS use folders to represent directories. This helps the user to visualize the directory as a folder that contains many papers and documents. The papers and documents represent files in the system.
With this tree hierarchy Windows and MacOS supports, one cannot just simply access a file from any point. He or she must access the file using a path.
For example, if the user is currently browing folder x, the only files he or she can access are the files listed in that folder. To access files found in folder y, the user must traverse the path from one directory to its subdirectory until he or she finally accesses the folder or directory that contains the file needed.
Historically, and even on some modern embedded devices, the file systems either do not support directories at all or only have a flat directory structure. This means subdirectories are not allowed.
There is only a group of top?level directories that containing files. This is similar to just having one directory for all your files.
The topmost directory in a file system is called the root directory. These directories contain other directories that are fittingly called subdirectories. The subdirectories may also contain subdirectories. This can go on and on indefinitely.
Depending on how an operating system supports directories, filenames in a directory can be viewed and ordered in various ways. They can be viewed and sorted alphabetically, by date, by size, or as icons in a graphical user interface.
The word directory is also used in computing and telephony with a different sense: a central repository of information related to management of a computer or a network of computers.
This includes data on applications, hosts, users, network devices, security credentials and more. This kind of directory, as opposed to a conventional database, is heavily optimized for easy reading.
Everybody who uses computers uses directories. Only, he or she may not notice it, or may not be aware of how this concept works. Most people make the most out of the directory concept by using it to organize their files.
If all their files were just dumped in a root directory, they would waste much time just trying to sort out the files that they need.
The concept of directories is constantly evolving. Even now, software developers and researchers are constantly devising ways to make organizing and sorting their files and directories easier. And as this researching continues, users can only gain from the tools directory management brings.
Oldest Computer In The World
11th July 2006,Apple Computer, Inc. is an American computer technology corporation, has been a major player in the evolution of personal computing since its founding in 1976
Apple develops, sells, and supports a series of personal computers, portable media players, computer software, and computer hardware accessories. The company's most well-known products are the Apple Macintosh line of personal computers, the iPod portable music player, and the iTunes media player.
Apple introduced the Lisa, the first commercial personal computer to employ a graphical user interface, which was influenced in part by the Xerox Alto.
In 1984, the Macintosh (commonly called the "Mac") was introduced, furthering the concepts of a user-friendly graphical user interface, and also introducing the mouse for the first time in a personal computer.
In 1991, Apple introduced the PowerBook line of portable computers, establishing the modern ergonomic form and design that has since become ubiquitous in the portable market.
In the 2000s, Apple expanded their focus on software to include professional and prosumer video, music, and photo production solutions, with a view to promoting their computers as a "digital hub". It also introduced iPod, a portable digital music player which has become the most popular player on the market.
Apple branched out into consumer electronics. One example of this product diversification was the Apple QuickTake digital camera, one of the first digital cameras ever brought to the consumer market.
Apple surprised its loyalists by allying with its long-time competitor IBM and CPU maker Motorola in the so-called AIM alliance. This was a bid to create a new computing platform (the PowerPC Reference Platform or PReP) which would use IBM and Motorola hardware coupled with Apple's software. As the first step toward launching the PReP platform, Apple started the Power Macintosh line in 1994, using IBM's PowerPC processor. This processor utilized RISC architecture.
Apple introduced a new all-in-one Macintosh reminiscent of the original Macintosh 128K: the iMac. it featured an innovative new translucent plastic exterior, originally in white and Bondi Blue, but later many other colors. The iMac proved phenomenally successful.
Apple purchased the Final Cut software from Macromedia, beginning their entry into the digital video editing market. IMovie was released in 1999 for consumers, and Final Cut Pro, a significant video editing program was released for professionals in the same year.
In later, Apple introduced Mac OS X, the operating system based on NeXT's OPENSTEP and BSD Unix.
On now days, apple releases its first Intel chip computer, a new note book computer known as the MacBook Pro and a new iMac.
