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

Offline browsing known as "Offline favourites" was Zastonj Download Emule removed as a feature in the most recent version of Internet Explorer 7, which only now supports single web page saving, but not browsing or storing an Zastonj Download Emule entire Zastonj Download Emule site offline.[citation needed]
Similarly, off-line storage is computer storage that is not "available for Zastonj Download Emule immediate use on demand by the system without human intervention", i.e it is storage that is off-line.
The ideas of "on-line" and "off-line" have been generalized from computing Zastonj Download Emule and telecommunication into the field of Zastonj Download Emule human interpersonal relationships. The Zastonj Download Emule distinction between what is considered Zastonj Download Emule "on-line" and Zastonj Download Emule 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), Zastonj Download Emule respectively. "On-line" Zastonj Download Emule 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 in relationships are Zastonj Download Emule more complex than a simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between Zastonj Download Emule an "on-line" relationship, such as indulging in cybersex, and an Linux Xp Download "off-line" relationship, such as being pen-pals. He also argues that even the telephone can be Zastonj Download Emule regarded as an "on-line" experience in some circumstances, and that the blurring of the distinctions between Zastonj Download Emule 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' Zastonj Download Emule meaningfully Zastonj Download Emule in the sense that was employed by the Zastonj Download Emule first generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures to reduce Zastonj Download Emule the distinction between "on-line" Zastonj Download Emule and "off-line", with Zastonj Download Emule a "general tendency to assimilate online to offline and erase the distinction", stressing, however, that this does not mean Zastonj Download Emule that on-line relationships are Zastonj Download Emule being reduced to pre-existing off-line relationships. He Zastonj Download Emule conjectures that greater legal status may be assigned Igra Tarok Download to on-line relationships (pointing out that contractual relationships, such as Zastonj Download Emule business transactions, on-line are Zastonj Download Emule already seen as just as "real" as Zastonj Download Emule their off-line counterparts), although he states it to be hard to imagine courts awarding palimony to people who have had Zastonj Download Emule a Zastonj Download Emule purely on-line sexual Zastonj Download Emule relationship. He also conjectures that an "on-line"/"off-line" distinction may be seen by people as "rather quaint and not quite comprehensible" Zastonj Download Emule within 10 years.[7]
The distinction Zastonj Download Emule 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 Zastonj Download Emule conventions Zastonj Download Emule of Zastonj Download Emule the desktop metaphor with its desktops, trash cans, folders, Zastonj Download Emule and so forth) the other way around. Several cartoons by The New Yorker have Zastonj Download Emule 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 Zastonj Download Emule items are Zastonj Download Emule actual size!", where shoppers may "Take it home as soon as you pay for it!", and where "Merchandise may be handled prior to purchase!". |
