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

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