A download manager is a Kandukonden Download computer program Kandukonden Download dedicated to the task of downloading (and sometime Kandukonden Download uploading) possibly unrelated stand-alone files from (and sometime to) the Internet for storage. This is Kandukonden Download unlike a World Wide Web browser, 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 Kandukonden Download of secondary importance. (A failed or incomplete Kandukonden Download web page file rarely ruins the page.) The typical Kandukonden Download download manager at a minimum provides means to recover from errors without losing the work Kandukonden Download already completed, and can optionally split the file to be downloaded Kandukonden Download (or uploaded) into 2 or more segments, which are then moved in parallel, potentially making the process Kandukonden Download faster within the limits of the available bandwidth. (A few servers are known to block moving files in parallel segments, Kandukonden Download on the principle that server Kandukonden Download capacity should be shared equally by all users.) Multi-source is the name given Kandukonden Download to files that are downloaded in parallel.
There are several Download Of Windows Media Player things that Kandukonden Download some web browsers are not very Kandukonden 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 Sap Database Manager Gui Download on poor connections.
Downloading several files from a site automatically according to Kandukonden Download simple rules (file types, Kandukonden Download updated files, etc. - see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, automatic hang-up and shutdown).
Searching Kandukonden Download for mirror sites, and the handling of different connections to download the same file more quickly (segmented Kandukonden Download downloading).
Download managers are useful for active Internet users. Kandukonden Download For dial-up users, they can automatically dial the Kandukonden Download internet service provider at night, when rates or tariffs are usually lower, download the specified Kandukonden Download files, and hang-up. They can record Kandukonden Download which links the user clicks on during the Kandukonden Download day, Kandukonden Download and queue these files for later download. For Kandukonden Download broadband users, download managers can help download very large files by resuming broken downloads, by limiting Kandukonden Download the Kandukonden Download bandwidth used, so that other internet activities are not affected (slowed) and the server is not overloaded, or by automatically navigating a site Kandukonden Download and downloading Kandukonden Download pre-specified content (photo galleries, MP3 collections, etc.) this can also include automatically Kandukonden Download downloading whole Kandukonden Download sites and regularly updating them (see Mirroring).
Many download managers Kandukonden Download support Metalink, an XML file listing mirrors, checksums, and other information Le Coeur Des Hommes Download useful for downloading.
See below for some examples Kandukonden Download of commonly used download managers. Some downloaders are Kandukonden Download optimized for a certain function. For example, Offline Explorer is designed to download Kandukonden Download entire websites.
Download managers, such as Go!Zilla, were among the first 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 (Kazaa, Kandukonden Download eMule, BitTorrent, Gnutella) and stream 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. Kandukonden Download Some software companies, for example Adobe [1], provide such Kandukonden Download downloaders for downloading Kandukonden Download software on their own site. Presumably this Kandukonden Download increases reliability and reduces tech support costs to them. Kandukonden Download A possible reason is increasing the control Kandukonden Download over redistribution of their software (even when the software is freeware).In computer technology Kandukonden Download and Harley Stage One Download telecommunication, on-line and off-line are defined by Federal Standard 1037C. They are states or conditions of Kandukonden Download a "device or equipment" or of "a functional unit". To Kandukonden Download be Kandukonden Download considered on-line, a device must be at least one of:
"Under the Free Download Full Games direct control of 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 Kandukonden Download operation"
"Functional and ready for service"
while a device that is off-line is not (e.g. it has "its main Kandukonden Download 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 Kandukonden Download either "on-line" or "off-line" states. One Kandukonden Download such Kandukonden Download MUA is Microsoft Outlook. When it is "on-line" it will Kandukonden Download attempt Kandukonden Download to connect to mail servers (to check for new mail at regular intervals, for Kandukonden Download example), and when it is "off-line" it will not attempt to make any Kandukonden Download such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect the connection status between the computer on which it is running and Internet. The user may have the computer itself on-line, connected to Kandukonden Download Internet via a cable modem or an ADSL connection, but may wish for Outlook Kandukonden Download to Kandukonden Download be off-line, so that it makes no attempt to send or to receive messages. Or the computer may be configured to employ a Kandukonden Download dial-up connection on demand (whenever an application such as Outlook attempts to make connection to a server), but the connection may Flv Download Web be an expensive telephone call from the particular Kandukonden Download location in Download Game Ps1 Psp which the computer currently happens to be (such as a hotel room) and the Kandukonden Download user Kandukonden Download may not wish Outlook to trigger making that call every Kandukonden Download 5 or 10 minutes to check for Kandukonden Download mail.[1]
Another example of the use of these Kandukonden Download concepts is in the world of digital audio technology. A tape recorder, digital editor, or other device that is Kandukonden Download "on-line" is one whose Kandukonden Download clock is Kandukonden Download under Kandukonden Download the control of the Kandukonden Download 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 Kandukonden Download its own internal clock. When a large number of devices Kandukonden Download are connected to a sync Kandukonden Download master, Kandukonden Download it is often convenient, if one wants Kandukonden Download to hear just Kandukonden Download the Kandukonden Download output of one single device, to take it off-line, because if the device is played back on-line all synchronized devices have to locate the Download Free Invoice Forms playback point and wait for each other to be in synchronization.[2] (For further related discussion, see MIDI timecode, 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 Kandukonden Download "on-line" or "off-line" states. The browser only attempts to fetch pages from servers whilst in Kandukonden Download 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 Kandukonden Download useful when the computer itself is also off-line, with connection to Internet expensive or impossible. Kandukonden Download The pages Kandukonden Download are either downloaded implicitly into the web browser's own Kandukonden Download cache, as a result of prior on-line browsing by the user, or explicitly by the browser being configured to keep local copies Kandukonden Download of certain web pages, which it keeps updated when the Kandukonden Download browser is in the on-line state, either by checking that the Kandukonden Download local copies Kandukonden Download are up-to-date at regular intervals or by checking 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 configured to Kandukonden Download download pages for offline browsing is Internet Explorer. When Kandukonden Download pages Kandukonden Download are added to the "Favourites" list, they can be marked for being made "available Download Pokemon Blue For Free for offline browsing". Internet Explorer will download to local copies both Kandukonden Download the marked page and, optionally, all of the pages that it links Kandukonden Download to. In Internet Explorer version 6, the level of direct and indirect links, the maximum Kandukonden Download amount of local Kandukonden Download disc space allowed Living Will Free Download Form Care to be consumed, and the schedule on which local copies are Kandukonden Download checked to see whether they Kandukonden Download are up-to-date, are configurable for each individual "Favourite" entry.

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