A download manager is a computer program dedicated to the task of Media Player Codec Download downloading (and sometime Download Free Dollhouse Plans uploading) Media Player Codec Download possibly unrelated stand-alone files from (and sometime to) the Internet for storage. This is unlike a World Wide Web browser, which is mainly intended to browse web pages, Media Player Codec Download composed of a Media Player Codec Download multitude of smaller files, where error-free moving of files for permanent storage is of secondary importance. (A failed or incomplete web page file rarely Media Player Codec Download ruins the page.) Macromedia Flash Mx Pro Download The typical download manager at a minimum provides means to recover from errors Media Player Codec Download without losing the work already completed, and can optionally split the file to Media Player Codec Download 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. (A few Media Player Codec Download servers are known to block moving files in parallel segments, on the Media Player Codec Download principle Media Player Codec Download that server capacity should be shared equally by all users.) Multi-source is the name given Media Player Codec Download to files that Media Player Codec Download are downloaded in parallel.
There are several things that some web browsers Media Player Codec Download are not very good at. That's Media Player Codec Download where the download managers enter the equation:
Pausing the downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor Media Player Codec Download connections.
Downloading several files Marathi Font Download from a Media Player Codec Download site automatically according to simple rules (file types, updated files, etc. - see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, automatic hang-up Media Player Codec Download and shutdown).
Searching for Media Player Codec Download mirror sites, and Media Player Codec Download the handling of different connections to download the same file more quickly (segmented downloading).
Download managers are useful for Media Player Codec Download active Internet users. For dial-up users, they can automatically dial the internet service provider at night, when Media Player Codec Download rates or tariffs are usually lower, download the specified files, and hang-up. They can record which links the user clicks on during the day, and queue these files for later download. For broadband users, download Media Player Codec Download managers can help download very large files by resuming Media Player Codec Download broken Soundtrack Mp3 Download downloads, by limiting the bandwidth used, so that other internet Media Player Codec Download activities are not affected (slowed) and the server is not overloaded, or by automatically navigating Media Player Codec Download a site and downloading Media Player Codec Download pre-specified content (photo galleries, Media Player Codec Download MP3 Media Player Codec Download collections, etc.) this can also include automatically Media Player Codec Download downloading whole sites and Media Player Codec Download regularly updating them (see Mirroring).
Many Media Player Codec Download 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 downloaders are optimized for a certain function. Media Player Codec Download For example, Offline Explorer is Media Player Codec Download designed Media Player Codec Download to download entire websites.
Download managers, such as Go!Zilla, were among the first adware applications Media Player Codec Download displaying a banner ad in the user Media Player Codec Download interface.
Related to Media Player Codec Download download managers are two other Media Player Codec Download breeds of Internet programs, file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such as StreamBox Media Player Codec Download VCR).
While download managers are designed to give users greater control over downloads, some downloaders are created to give that control to content Media Player Codec Download distributors instead. Some software companies, for example Adobe [1], provide such downloaders for downloading software on their own site. Presumably Ipod Mini Download this increases reliability and reduces tech support costs to them. A possible reason is increasing the control over redistribution of their software (even when the software is Media Player Codec Download freeware).In computer technology and Media Player Codec Download telecommunication, on-line and off-line are defined by Federal Standard 1037C. They are states or conditions of a "device or equipment" or of "a Media Player Codec Download functional Media Player Codec Download unit". To be Media Player Codec Download considered on-line, a device must be at least one of:
"Under the direct control Media Player Codec Download of another device"
"Under the direct control Free Hindi Mp3 Songs Download of Media Player Codec Download 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 Media Player Codec Download service"
while a device Media Player Codec Download that is off-line is Media Player Codec Download not (e.g. it has "its main power source disconnected or turned off", and is "off-power").
One example of a common use of these concepts is a Mail User Agent that can be instructed to be in either "on-line" or "off-line" states. One such MUA is Microsoft Outlook. When it is "on-line" Media Player Codec Download it will attempt to Media Player Codec Download connect to mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" it Media Player Codec Download will 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 Ogm Codec Download on which it is running and Internet. The user Media Player Codec Download may have the computer itself on-line, connected to Internet via a cable modem or Media Player Codec Download an ADSL connection, but may wish for Outlook to Media Player Codec Download be off-line, so that it makes no attempt to send or to receive messages. Or the computer may Media Player Codec Download be configured to employ a dial-up connection on demand (whenever an application such as Outlook attempts to make connection Media Player Codec Download to a server), but the connection may be Media Player Codec Download an expensive telephone call Media Player Codec Download from the particular location in which the computer currently happens to be (such as a hotel room) and the user may not wish Outlook to trigger making that call every 5 Free Download Music Videos Htm or 10 minutes to check for mail.[1]
Another example of the use of Media Player Codec Download these concepts Media Player Codec Download is in the world Media Player Codec Download of digital audio technology. A tape recorder, digital editor, or other device Media Player Codec Download that is "on-line" is one whose clock is under the Media Player Codec Download control of the clock of a "synchronization master" Media Player Codec Download device. When the Media Player Codec Download sync master commences playback, the Media Player Codec Download "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" Media Player Codec Download uses no external clock reference and relies Media Player Codec Download upon its own internal clock. When a large Download Game Boy Colour Emulator Games number of devices are connected to a sync master, it is often convenient, if Media Player Codec Download one wants to hear just the output of Media Player Codec Download one single device, to take it off-line, because Wall Hack Aim Bot Download if the device is played Media Player Codec Download back on-line all synchronized devices have to locate the playback point and wait for Media Player Codec Download each other to be in Media Player Codec Download synchronization.[2] (For further related discussion, see MIDI timecode, Media Player Codec Download word sync, and recording system synchronization.)
A third example of a common use of these concepts 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 Media Player Codec Download pages can be browsed using local copies of those pages that have previously been downloaded whilst in the "on-line" state. This can be useful when the Media Player Codec Download computer itself is also off-line, with connection to Internet expensive Media Player Codec Download or impossible. The pages are either downloaded implicitly into the web browser's Media Player Codec Download own cache, as a Media Player Codec Download result of prior on-line browsing by the user, or explicitly by the browser being configured to keep local copies of certain web pages, which it keeps Media Player Codec Download 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 Media Player Codec Download by checking that the local copies are up-to-date whenever the browser is switched to Media Player Codec Download the on-line state. One Media Player Codec Download such web Media Player Codec Download browser Media Player Codec Download capable of being explicitly configured to Media Player Codec Download download pages for offline browsing is Internet Explorer. When Media Player Codec Download pages are added to the "Favourites" list, they can be marked for Free Hindi Vedio Songs Download 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 Media Player Codec Download links to. In Internet Explorer version 6, Media Player Codec Download the level of direct and indirect links, the maximum amount of local disc space allowed Media Player Codec Download to be consumed, and the schedule on which local copies Media Player Codec Download are checked to see whether they are up-to-date, are Media Player Codec Download configurable for each Media Player Codec Download individual "Favourite" entry.

Offline browsing Media Player Codec Download known Media Player Codec Download as "Offline favourites" Media Player Codec Download was removed as a feature in the most recent Media Player Codec Download version of Internet Media Player Codec Download Explorer Media Player Codec Download 7, Media Player Codec Download which only now supports single web page saving, but Media Player Codec Download not Media Player Codec Download browsing or storing an entire site offline.[citation needed]
Similarly, off-line storage is computer storage that is not "available for immediate use on demand by the system without human intervention", i.e it is storage that is off-line.
The ideas Media Player Codec Download of "on-line" and "off-line" have been generalized from computing Media Player Codec Download and telecommunication into the field of human interpersonal relationships. The distinction between what is considered "on-line" and what is Media Player Codec Download considered "off-line" has Media Player Codec Download become a subject of study in the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as Media Player Codec Download the distinction between computer-mediated Media Player Codec Download communication Media Player Codec Download and face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, and "off-line" is reality (e.g. Media Player Codec Download real life or Commodore Download meatspace). Slater states that this distinction is "obviously far too simple". To support his argument that the distinctions in relationships are more complex than a simple "on-line"/"off-line" dichotomy, Media Player Codec Download he observes that some people draw no distinction between Media Player Codec Download an "on-line" relationship, such as indulging in cybersex, and an "off-line" Media Player Codec Download relationship, such Media Player Codec Download as being pen-pals. He also argues that even the telephone can be regarded as an "on-line" experience in some circumstances, and Media Player Codec Download that the blurring of the Media Player Codec Download distinctions between the Media Player Codec Download uses of various technologies Media Player Codec Download (such as PDA and mobile telephone, television and Internet, and telephone Media Player Codec Download and voice-over-IP) has made Media Player Codec Download it "impossible to use the term Media Player Codec Download 'on-line' meaningfully in Media Player Codec Download the sense that was employed by the first generation of Internet research".[7]
Slater asserts Media Player Codec Download that there are legal and regulatory pressures to reduce the distinction between "on-line" and "off-line", with a Media Player Codec Download "general tendency Media Player Codec Download to assimilate online to offline and erase the distinction", stressing, however, that this does not mean that Media Player Codec Download on-line relationships are being reduced to pre-existing off-line relationships. He conjectures that greater legal status may be assigned to on-line relationships (pointing out Media Player Codec Download that Media Player Codec Download contractual relationships, such as business transactions, on-line are already seen as just as "real" as their off-line Win98 Download Os counterparts), although Media Player Codec Download he states it to be hard to imagine courts awarding palimony to people who have had a purely on-line Media Player Codec Download sexual relationship. He also conjectures that an "on-line"/"off-line" distinction Media Player Codec Download may be seen Media Player Codec Download 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 to define and to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, Media Player Codec Download trash cans, folders, and so forth) the other way around. Several Flash Website Design Download 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 Media Player Codec Download illustrates "the off-line store" where "All items Media Player Codec Download are actual size!", where shoppers may "Take it Media Player Codec Download home as soon as you pay for it!", and Media Player Codec Download where "Merchandise Media Player Codec Download may be handled prior to purchase!". |
