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

Offline browsing known as "Offline favourites" was removed as a feature Yu Muzika Download in the most recent version of Internet Yu Muzika Download 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 immediate use on demand by the system without human intervention", Demons Tools Free Download i.e it is storage Yu Muzika Download that is off-line.
The ideas of "on-line" Yu Muzika Download and "off-line" have 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 Yu Muzika Download become a subject of study in the field of sociology.[7]
The distinction Download Naruto between "on-line" Mp3 Music Download and "off-line" is Yu Muzika Download conventionally seen as the distinction between computer-mediated communication Yu Muzika Download and face-to-face communication Yu Muzika Download (e.g. face time), respectively. "On-line" is virtuality, and "off-line" is reality Yu Muzika Download (e.g. real life or meatspace). Yu Muzika Download 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, he observes that some people draw no distinction between an Full Free The Sims Download "on-line" relationship, such as indulging in cybersex, and an "off-line" relationship, such as being pen-pals. He also argues that Yu Muzika Download even the telephone can be regarded as an "on-line" experience in some Yu Muzika Download 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 Yu Muzika Download and voice-over-IP) Yu Muzika Download has made it "impossible to use the term 'on-line' meaningfully in the Yu Muzika Download sense that was employed by the Yu Muzika Download first generation of Internet research".[7]
Slater asserts Yu Muzika Download that Yu Muzika Download there are legal and regulatory pressures to reduce Yu Muzika Download the distinction Yu Muzika Download between Yu Muzika Download "on-line" and "off-line", with a "general tendency to assimilate online to offline and erase the distinction", Yu Muzika Download stressing, however, that this does not mean that on-line Yu Muzika Download relationships are being reduced to pre-existing off-line relationships. He conjectures Download Spybot that greater legal status may be Yu Muzika Download assigned Yu Muzika Download to on-line relationships (pointing out that Yu Muzika Download contractual relationships, Yu Muzika Download such as business transactions, on-line are already seen as just as Yu Muzika Download "real" as their off-line counterparts), although he states it to be hard to imagine courts awarding palimony Yu Muzika Download to Yu Muzika Download people who have had a purely on-line sexual relationship. Yu Muzika Download He also conjectures that Yu Muzika Download an "on-line"/"off-line" distinction may be seen by people as "rather quaint and not quite comprehensible" within Yu Muzika Download 10 years.[7]
The distinction where "on-line" is seen as virtuality and "off-line" as reality is sometimes inverted, with Yu Muzika Download "on-line" concepts being used to define and Yu Muzika Download to explain "off-line" activities, rather Yu Muzika Download than (as per the conventions Yu Muzika Download of the desktop metaphor Yu Muzika Download with its Yu Muzika Download desktops, trash cans, folders, and Yu Muzika Download so forth) the Yu Muzika Download 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 Yu Muzika Download admitting a Yu Muzika Download man Yu Muzika Download into Heaven. Another Yu Muzika Download illustrates "the off-line store" where "All items are actual size!", where shoppers may "Take it home as soon as you pay for it!", and where "Merchandise may be handled prior to purchase!". |
