A download High School Musical Download Free manager is a computer program dedicated to the task of downloading (and sometime uploading) possibly unrelated stand-alone files High School Musical Download Free from (and sometime to) the Internet for storage. This is unlike a High School Musical Download Free World Wide Web browser, which is mainly intended High School Musical Download Free to browse web pages, composed of High School Musical Download Free a High School Musical Download Free multitude of smaller files, where High School Musical Download Free error-free moving of files for permanent storage is of secondary High School Musical Download Free importance. (A failed High School Musical Download Free or incomplete web page file rarely ruins the High School Musical Download Free page.) The typical download manager at a minimum provides means to recover from errors without losing the work High School Musical Download Free already completed, and can optionally split the file to be downloaded (or uploaded) into 2 or more segments, which are then moved in parallel, potentially making the process faster within the limits of the available bandwidth. High School Musical Download Free (A few High School Musical Download Free servers are known to block moving files in parallel segments, on the principle that server capacity should be shared High School Musical Download Free equally by all users.) Multi-source High School Musical Download Free is the name given to files that are downloaded in parallel.
There are High School Musical Download Free several things that some web High School Musical Download Free browsers are not High School Musical Download Free very good at. That's where the download managers enter the equation:
Pausing the downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading High School Musical Download Free files on poor connections.
Downloading several High School Musical Download Free files from a site automatically High School Musical Download Free according to High School Musical Download Free simple rules (file types, updated files, etc. - see High School Musical Download Free also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, automatic hang-up and shutdown).
Searching for mirror sites, and the handling of different connections to download the same file more quickly (segmented downloading).
Download managers are useful for High School Musical Download Free active Internet users. For dial-up users, they can automatically dial the internet service High School Musical Download Free provider at night, when rates or tariffs are usually lower, download the specified High School Musical Download Free files, and hang-up. They can record High School Musical Download Free which links the user clicks on during High School Musical Download Free the day, and queue these files for later download. High School Musical Download Free For broadband users, download High School Musical Download Free managers High School Musical Download Free can help download very large files by resuming High School Musical Download Free broken downloads, by High School Musical Download Free limiting the High School Musical Download Free bandwidth used, so that other internet activities High School Musical Download Free are not affected (slowed) High School Musical Download Free Rpgmaker2000 Game Download and the server is not overloaded, or by automatically navigating a site and High School Musical Download Free downloading pre-specified content (photo galleries, MP3 collections, etc.) this can also include automatically High School Musical Download Free downloading whole sites Free Web Browsers Download and regularly updating them (see Mirroring).
Many download managers support Metalink, an XML file listing mirrors, checksums, and other information useful for downloading.
See below for some examples of commonly used download managers. Some High School Musical Download Free downloaders are optimized for High School Musical Download Free a High School Musical Download Free certain function. For example, Offline Explorer is designed to download entire websites.
Download managers, High School Musical Download Free such as Go!Zilla, were among the first adware High School Musical Download Free applications displaying a banner ad High School Musical Download Free in Free Shareaza Download the user interface.
Related High School Musical Download Free to download managers are two other breeds of Internet programs, file-sharing High School Musical Download Free peer-to-peer applications High School Musical Download Free (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders High School Musical Download Free (such as StreamBox VCR).
While download managers are designed to give users greater control over downloads, some downloaders are High School Musical Download Free created to give that control to High School Musical Download Free content distributors instead. Some software companies, for example Adobe [1], provide such downloaders High School Musical Download Free for downloading software on their own site. Warcraft Free Download Presumably this increases reliability and reduces tech support costs to them. A possible reason High School Musical Download Free is increasing the control over redistribution of their software (even when the software is freeware).In computer technology and telecommunication, High School Musical Download Free on-line and off-line are defined by Federal Standard 1037C. They are states or conditions of a High School Musical Download Free "device or equipment" or of "a functional unit". To be considered on-line, a device must be at least one High School Musical Download Free of:
"Under the direct control of High School Musical Download Free another device"
"Under the direct control of the system with which it is associated"
"Available for immediate use on demand by the system without human intervention"
"Connected to a system, and is in operation"
"Functional and ready for service"
while a device that is off-line is not (e.g. it has "its main power source High School Musical Download Free disconnected or High School Musical Download Free turned off", and is "off-power").
One example of a common use of these concepts is a Mail User Agent that can be High School Musical Download Free instructed Poweriso Download to be in either "on-line" or "off-line" states. One such MUA is Microsoft Outlook. When it is "on-line" it will attempt to connect to mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" it will High School Musical Download Free not attempt to make any such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect the connection status between the computer on High School Musical Download Free which High School Musical Download Free it is running and Internet. The user may have the Download Vlc computer itself on-line, High School Musical Download Free connected to Internet via a High School Musical Download Free cable modem or an ADSL connection, but may wish for Outlook to be off-line, so that it makes no High School Musical Download Free attempt to send or to High School Musical Download Free receive messages. Or the computer may be configured to employ a dial-up connection on demand (whenever an application High School Musical Download Free such as Outlook attempts to make High School Musical Download Free connection to a server), but the connection may be High School Musical Download Free an expensive telephone call from the particular location in which the computer currently happens to be (such as a hotel room) High School Musical Download Free and the user may not wish Outlook to trigger High School Musical Download Free making that call every 5 or 10 minutes to check High School Musical Download Free for mail.[1]
Another example of the High School Musical Download Free use of these concepts is in the world of High School Musical Download Free digital audio technology. A tape recorder, digital editor, or other device that is "on-line" is one whose High School Musical Download Free clock is under the control High School Musical Download Free of the clock of a "synchronization master" device. When the sync master commences playback, the "on-line" device automatically synchronizes itself to the master and commences playing from the same point in the recording. Whereas a device that is "off-line" uses no external clock reference and relies upon its own internal clock. When a large number of devices are connected to a sync master, it is often convenient, if High School Musical Download Free one wants to hear just the output of one single device, to take it off-line, because if the device is played back on-line all High School Musical Download Free synchronized devices have to locate the playback point and wait for each other to be in synchronization.[2] (For further related discussion, High School Musical Download Free see High School Musical Download Free MIDI High School Musical Download Free timecode, word sync, and recording system synchronization.)
A third example of a common use of these concepts is a High School Musical Download Free web browser that High School Musical Download Free can be instructed to be High School Musical Download Free in either "on-line" or "off-line" states. The browser High School Musical Download Free only High School Musical Download Free attempts to fetch pages from servers whilst in High School Musical Download Free the "on-line" state. In the "off-line" state, users can perform offline browsing, where pages High School Musical Download Free can High School Musical Download Free be browsed using local High School Musical Download Free copies of those pages that have previously been downloaded whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with connection to Internet High School Musical Download Free expensive or impossible. The pages are either downloaded implicitly into the web browser's own cache, as a result of prior on-line browsing by the user, High School Musical Download Free or explicitly by the browser being configured to keep local copies of certain High School Musical Download Free web pages, which it keeps updated when the browser is High School Musical Download Free in the High School Musical Download Free on-line High School Musical Download Free state, either by checking that the local copies are up-to-date at High School Musical Download Free regular intervals or by checking High School Musical Download Free that the local copies are up-to-date whenever the browser is switched to the on-line state. One such web browser capable of being explicitly Download Win Xp Sp2 configured to download pages for offline browsing is Internet Explorer. When pages are added to the "Favourites" list, they High School Musical Download Free can be marked for being made "available for offline browsing". Internet Explorer will download to local copies both High School Musical Download Free the marked page and, optionally, High School Musical Download Free all of the pages that High School Musical Download Free it links to. In Internet Explorer version 6, the level High School Musical Download Free of direct and indirect links, High School Musical Download Free the maximum amount of local disc space allowed to be consumed, and the schedule on which local copies are checked to see whether they High School Musical Download Free are up-to-date, High School Musical Download Free are configurable High School Musical Download Free for each individual "Favourite" entry.

Offline browsing known as "Offline favourites" was removed as a feature in the most recent version High School Musical Download Free of Internet Explorer 7, which only now supports single web page saving, but not browsing or storing an entire site offline.[citation needed]
Similarly, off-line storage is computer storage that is not "available for High School Musical Download Free immediate use on demand by the system without High School Musical Download Free human intervention", i.e it Download Episode Free Simpsons is storage that is off-line.
The ideas of "on-line" and "off-line" have been generalized High School Musical Download Free from computing and telecommunication into the field of human interpersonal relationships. The distinction between what is considered "on-line" and what High School Musical Download Free is considered "off-line" has become a subject of study in the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as the distinction between computer-mediated communication and face-to-face communication (e.g. face time), respectively. "On-line" High School Musical Download Free is virtuality, and "off-line" is reality (e.g. real life or meatspace). Slater states that this distinction is "obviously far too simple". To support his argument that the distinctions High School Musical Download Free in relationships are more complex than a High School Musical Download Free simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction High School Musical Download Free between an "on-line" relationship, such as indulging in cybersex, and an "off-line" relationship, such as being pen-pals. He also argues that even the telephone can be High School Musical Download Free regarded as an "on-line" experience in some circumstances, High School Musical Download Free and that High School Musical Download Free the blurring of the distinctions between the uses of various technologies (such as PDA High School Musical Download Free and mobile telephone, television and Internet, and telephone and voice-over-IP) has made it "impossible to use High School Musical Download Free the term High School Musical Download Free 'on-line' meaningfully in the sense that High School Musical Download Free was employed by the first generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures to reduce the distinction High School Musical Download Free between "on-line" and "off-line", with High School Musical Download Free a "general tendency to assimilate online to offline and erase the distinction", stressing, however, that this High School Musical Download Free does not mean that High School Musical Download Free on-line relationships are being reduced to pre-existing off-line relationships. He conjectures that greater legal High School Musical Download Free status may be assigned to on-line relationships (pointing out that High School Musical Download Free contractual relationships, such as business transactions, on-line are already High School Musical Download Free seen as just as "real" as High School Musical Download Free their off-line counterparts), although he states it to be hard to imagine courts awarding palimony to people who have had a purely High School Musical Download Free on-line sexual relationship. High School Musical Download Free He also conjectures that an "on-line"/"off-line" distinction may be seen by people as "rather quaint and not quite comprehensible" within 10 years.[7]
The distinction where "on-line" is seen as virtuality and "off-line" as reality is High School Musical Download Free sometimes inverted, with "on-line" concepts being used High School Musical Download Free to define and to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash cans, High School Musical Download Free folders, and so forth) the High School Musical Download Free other way around. Several cartoons by The New Yorker have satirized this. One includes Saint Peter asking for a user name and a password before admitting a man into Heaven. Another illustrates "the off-line store" where "All items are actual size!", where shoppers may High School Musical Download Free "Take it home as soon as you pay for it!", and where High School Musical Download Free "Merchandise may be handled High School Musical Download Free prior to purchase!". |
