A download manager is Springbreak Download a computer program Springbreak Download dedicated to Springbreak Download Download Audio Old Testament Bible the task of downloading (and sometime Springbreak Download uploading) possibly unrelated stand-alone files from (and sometime to) Springbreak Download the Internet Cricket Flash Download for storage. This is unlike a World Wide Web browser, which is mainly intended to browse web pages, composed of Springbreak Download a multitude of smaller files, Springbreak Download where error-free moving of files for permanent storage is of secondary importance. (A failed or incomplete Springbreak Download web page file rarely ruins the page.) The typical download manager at a Springbreak Download minimum Springbreak Download provides means to recover from errors without losing the Springbreak Download work already Springbreak Download completed, and can optionally split the file to Springbreak Download be downloaded (or uploaded) into 2 or more segments, which are then moved in parallel, potentially making Springbreak Download the process Springbreak Download faster within the limits of the available bandwidth. (A few servers are known to Springbreak Download block moving files in parallel segments, on the principle that Springbreak Download server capacity should be shared equally by all users.) Multi-source Springbreak Download is the name given to Springbreak Download files that are downloaded in parallel.
There are several things that some web browsers Springbreak Download are not Springbreak Download very good at. That's where the download managers enter the equation:
Pausing the downloading of large files.
Resuming broken Springbreak Download or paused downloads (especially for very large files).
Downloading files on Springbreak Download poor connections.
Downloading several files from a 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 and Springbreak Download shutdown).
Searching for mirror sites, and the handling of different Springbreak Download connections to download the same Springbreak Download file Springbreak Download more quickly (segmented downloading).
Download Springbreak Download managers are useful for active Internet users. For dial-up users, Springbreak Download they can automatically dial the internet service provider Springbreak Download at Springbreak Download night, when Springbreak 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 Springbreak Download day, and queue these files for later download. For broadband users, download managers can help download very large files Springbreak Download by resuming broken Springbreak Download downloads, Springbreak Download by limiting the bandwidth used, so that other internet activities are not affected Springbreak Download (slowed) Springbreak Download and the server is not overloaded, or by automatically navigating Springbreak Download a site and downloading pre-specified content (photo galleries, MP3 collections, etc.) this can also include automatically downloading whole sites and regularly updating them (see Mirroring).
Many download managers support Metalink, an XML file Springbreak Download listing mirrors, checksums, and other information useful Springbreak Download for downloading.
See below for some examples of commonly used download managers. Some downloaders are optimized for a certain function. Springbreak Download For example, Offline Explorer is designed to download entire websites.

Download managers, such as Go!Zilla, were among Springbreak Download the first adware Springbreak Download applications displaying a banner ad in the user interface.
Related to download managers are two Springbreak Download other breeds of Internet programs, file-sharing Springbreak Download peer-to-peer Springbreak Download applications (Kazaa, Springbreak 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 Springbreak Download that control to content distributors instead. Some software companies, for example Adobe Springbreak Download [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 Springbreak Download the control over redistribution of their software (even when the Springbreak Download software is freeware).In computer technology Springbreak Download and telecommunication, on-line and off-line are defined by Federal Standard 1037C. They are states or conditions of a "device or equipment" or Springbreak Download of "a functional unit". To be considered on-line, a device must be Springbreak Download at least Springbreak Download one of:
"Under Springbreak Download the direct control of Springbreak Download another device"
"Under the direct control of the system with which it is Springbreak Download associated"
"Available for immediate use on Springbreak Download demand by the system without human intervention"
"Connected to a system, and is in operation"
"Functional and ready Springbreak Download for service"
while a device that is Springbreak Download 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 Nz Video Download Mail User Springbreak Download Agent that can be instructed to be in either "on-line" or "off-line" states. One such MUA is Microsoft Springbreak Download Outlook. When it 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 Springbreak Download not attempt to make any such connections. Springbreak Download 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 Springbreak Download user Springbreak Download may have the computer itself on-line, connected to Free Download Anti Spyware Win Internet via a cable modem or an ADSL connection, but may wish for Outlook to be off-line, so that Springbreak Download it makes no Springbreak Download attempt to send or to receive messages. Or the Springbreak Download computer may be configured to employ a dial-up connection on Springbreak Download demand (whenever Springbreak Download an application such as Outlook attempts to make Springbreak Download connection to a server), but the connection may be an expensive telephone call from the particular location in which the computer currently happens to Springbreak Download be (such as a hotel room) and the user may not wish Outlook to trigger Springbreak Download making that call every 5 or 10 minutes to check for mail.[1]
Another example of the use of these concepts is in the world of digital audio technology. A tape recorder, digital editor, or other device that is "on-line" is one whose clock is under the control of the Springbreak 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 Springbreak Download recording. Whereas a device that is "off-line" uses no external clock reference and relies upon its own internal clock. When Vegetable Garden Layout Download a Springbreak Download large number of devices are Springbreak Download connected to a sync master, it is Springbreak Download often convenient, if Springbreak Download one wants to hear just the output of one single device, to Springbreak Download take it off-line, because if the device is Springbreak Download played back on-line all synchronized devices have to locate the 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 Springbreak Download to be in Free Songs Download To Pc either "on-line" Springbreak Download or "off-line" states. The browser Springbreak Download 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 Springbreak Download pages Springbreak Download that have previously been downloaded Springbreak Download whilst 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 Springbreak Download 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 the browser being configured to keep local copies of certain web pages, which it keeps updated Springbreak Download when the browser is in the on-line state, either by checking that the local copies are up-to-date at regular Springbreak Download 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 Springbreak Download of being explicitly configured to download pages for offline browsing is Internet Explorer. When Springbreak Download pages are added to the "Favourites" list, Springbreak Download they can Springbreak Download be marked for being made "available for offline browsing". Internet Springbreak Download Explorer will download to local Springbreak Download copies both Springbreak Download the marked page and, optionally, all of the pages Springbreak Download that it links Springbreak Download to. In Internet Explorer version 6, the Conveyancing Draft Contract Download level of direct and indirect links, the maximum amount of Springbreak Download local Springbreak Download 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 Springbreak Download individual "Favourite" entry.

Offline Springbreak Download 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 Springbreak Download saving, but not browsing or storing an entire Springbreak Download site offline.[citation needed]
Similarly, off-line storage is computer storage that is not "available for Springbreak Download immediate use on demand by the system without human intervention", Springbreak Download i.e Springbreak Download it is storage that is off-line.
The ideas of "on-line" and "off-line" have been generalized from computing and telecommunication Springbreak Download into the field of human interpersonal relationships. The Springbreak Download distinction between what is considered "on-line" and what is considered "off-line" has become Springbreak Download a subject of study in the field of sociology.[7]
The distinction between Springbreak Download "on-line" and Springbreak Download "off-line" is conventionally seen as Springbreak Download the distinction between computer-mediated communication and Springbreak Download face-to-face communication (e.g. face time), respectively. "On-line" 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 Springbreak Download 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 "on-line" Vocabulary Energizers Free Download relationship, such as indulging Springbreak Download Dino Island Game Download 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 Springbreak Download in Springbreak Download some circumstances, Springbreak Download and that the Springbreak Download 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 Apple Quick Time Download 'on-line' meaningfully Springbreak Download in the sense that was employed by the first generation of Internet research".[7]

Slater asserts 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 offline and erase the distinction", stressing, however, that this does not mean that on-line relationships are being reduced Springbreak Download to pre-existing off-line relationships. Springbreak Download He conjectures Springbreak Download that greater legal status may be assigned to on-line relationships (pointing out that contractual relationships, Springbreak Download such as business transactions, on-line are already seen as just as Springbreak Download "real" as their off-line counterparts), although he states it to be hard to imagine courts awarding palimony to people who have had a purely on-line sexual Springbreak Download relationship. He also conjectures that an "on-line"/"off-line" distinction may be seen by Springbreak Download 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 Springbreak Download being used to Springbreak Download define and to explain "off-line" activities, rather than (as per the conventions Springbreak Download of the desktop metaphor Springbreak Download with its desktops, trash cans, folders, and so forth) the other Springbreak Download way around. Several cartoons by The New Yorker have satirized this. One includes Saint Peter asking Springbreak Download for a user name and a password before admitting a man into Heaven. Another illustrates "the off-line store" where "All items are actual size!", where shoppers may Halo Aim Bot Download "Take it home as soon as you pay for it!", and where "Merchandise may be Springbreak Download handled prior Springbreak Download to purchase!". |
