A download manager is a computer program dedicated to Warcraft Free Download the task Download Dbz Rpg of downloading (and sometime uploading) possibly unrelated stand-alone files from (and Warcraft Free Download sometime to) the Internet for storage. This is unlike a World Wide Web browser, which is Undisputed Mp3 Download Bring It On mainly intended to browse web pages, composed of a multitude of smaller files, where Warcraft Free Download error-free moving of files for permanent storage is of secondary importance. (A failed or incomplete web page file rarely Warcraft Free Download ruins the page.) The typical download manager at a minimum provides means to recover from errors without losing the work already completed, and can optionally split the file Warcraft Free Download to be downloaded Warcraft Free Download (or Warcraft Free Download uploaded) into 2 Sabayon Download or more segments, which are then moved in parallel, potentially making Warcraft Free Download the process faster within the limits of the available bandwidth. Warcraft Free Download (A few servers Warcraft Free Download are known to block moving files in Warcraft Free Download parallel segments, on the principle that server capacity should be shared equally by all users.) Multi-source is Warcraft Free Download the name given to files that are downloaded Warcraft Free Download in parallel.
There are several things that some web Warcraft Free Download browsers are not very good at. That's where the download managers enter the equation:
Pausing the downloading of large files.
Resuming Warcraft Free Download broken or paused downloads (especially for very large files).
Downloading files Warcraft Free Download on poor connections.
Downloading several files from Warcraft Free Download a site automatically according to simple rules (file types, updated files, etc. - see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, Warcraft Free Download automatic hang-up and Warcraft Free Download shutdown).
Searching for mirror sites, and the handling of different connections to download the same file more quickly (segmented downloading).
Download managers Warcraft Free Download are useful for active Internet users. For dial-up users, they can automatically dial the internet service provider at night, when rates or tariffs are usually Warcraft Free Download lower, download the specified files, and Dsj Download hang-up. They can record which links Warcraft Free Download the user clicks on during Warcraft Free Download the day, and queue these files for later download. For broadband users, download managers can help download very Warcraft Free Download large Warcraft Free Download files by resuming broken downloads, by limiting the bandwidth used, so Warcraft Free 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 galleries, MP3 collections, etc.) this can also include automatically downloading whole sites and regularly updating them (see Mirroring).
Many download Warcraft Free Download managers support Metalink, an XML file Warcraft Free Download 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. For example, Warcraft Free Download Offline Explorer is designed to download Warcraft Free Download entire Warcraft Free Download websites.
Download managers, such as Go!Zilla, were among the first adware Warcraft Free Download applications displaying Warcraft Free Download a banner Warcraft Free Download ad in the user interface.
Related Warcraft Free Download to download managers are two other breeds of Internet programs, file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such as StreamBox VCR).
While download managers are designed to give users greater control over downloads, Warcraft Free Download some downloaders are created to give that control to content distributors instead. Some Warcraft Free Download software companies, for example Adobe [1], provide such downloaders for downloading software on their own site. Presumably this increases reliability and reduces tech support costs to them. Warcraft Free Download A possible reason is increasing the control over redistribution of their software (even when Warcraft Free Download the software is freeware).In computer technology and telecommunication, on-line and off-line Warcraft Free Download are defined by Federal Standard 1037C. They are states or Warcraft Free Download conditions of a "device or equipment" or of "a functional unit". To be considered on-line, a device Warcraft Free Download must Warcraft Free Download be at least one of:
"Under the direct control of another device"
"Under the direct control of the system with which it is associated"
"Available for immediate use on Warcraft Free Download demand by the system without human intervention"
"Connected to a system, and is in operation"
"Functional and ready Warcraft Free Download for service"
while a device that is off-line is not (e.g. it has "its Warcraft Free Download main Warcraft Free Download power source disconnected or Warcraft Free Download turned off", and is Warcraft Free Download "off-power").
One Warcraft Free Download example of a common use of these concepts is a Mail User Warcraft Free Download Agent that Warcraft Free Download can be instructed to be Warcraft Free Download in either "on-line" or "off-line" states. One such MUA is Microsoft 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 Warcraft Free Download it is "off-line" it will not Warcraft Free Download attempt to make any such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect the Warcraft Free Download connection status between the computer on which it is running and Internet. The user may have the computer itself on-line, connected to Warcraft Free Download Internet via Shareaza Download a cable modem or an ADSL connection, but may wish for Outlook to be off-line, so that Warcraft Free Download it makes no Warcraft Free Download attempt to send or to receive messages. Or the computer may be configured to Warcraft Free Download employ a dial-up connection Warcraft Free Download on demand (whenever an application such as Outlook attempts to make Warcraft Free 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 be (such as a hotel room) Warcraft Free Download and the user may not wish Outlook to trigger making that call every 5 or 10 Warcraft Free Download 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 Warcraft Free Download is under the control Warcraft Free Download of the clock of a "synchronization Warcraft Free Download master" device. Warcraft Free Download When the sync Warcraft Free Download 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 Warcraft Free Download device that is "off-line" uses no external clock reference and relies upon its own internal Warcraft Free Download clock. When a large number of devices are connected to a sync master, it is often convenient, if Warcraft Free Download one wants to hear just the output Warcraft Free Download of one single device, to take it off-line, because if the device is played Warcraft Free Download back on-line all synchronized devices have to locate the playback point and wait for Warcraft Free Download each other to be in synchronization.[2] (For further related discussion, see MIDI timecode, word sync, Warcraft Free Download and recording system synchronization.)
A third example of Warcraft Free Download a common use of these concepts is Warcraft Free Download a web browser that can be Warcraft Free Download instructed to be in either "on-line" or "off-line" states. The browser only attempts to fetch Warcraft Free Download pages from servers whilst in the "on-line" state. In the "off-line" state, users can perform offline Warcraft Free Download browsing, where pages can be browsed using local copies of those pages that have Warcraft Free Download previously been downloaded whilst Warcraft Free Download in the Warcraft Free Download "on-line" state. This can be useful when the computer itself is also Warcraft Free Download off-line, with connection to Internet expensive or impossible. The 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 when the browser is in the on-line state, either by Warcraft Free Download checking that the local copies 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 Warcraft Free Download state. One such web browser Warcraft Free Download capable of being explicitly configured to download pages for Warcraft Free Download offline browsing is Internet Explorer. When pages Warcraft Free Download are added to the "Favourites" list, they can Warcraft Free Download be marked for being made "available for offline browsing". Internet Explorer will download to local copies both the marked page and, optionally, all Warcraft Free Download of the pages that it links to. In Internet Explorer version 6, Warcraft Free Download the level of direct and indirect links, the maximum Warcraft Free Download amount of local disc space allowed Warcraft Free Download to be consumed, and the schedule on which local copies are checked to see whether they are up-to-date, Warcraft Free Download are configurable for each individual "Favourite" Warcraft Free Download entry.

Offline browsing known as "Offline favourites" was removed as a feature in the most recent version of Internet Explorer 7, which only Warcraft Free 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 that is not "available for immediate Warcraft Free Download use on demand by the system without human intervention", i.e it is storage that Warcraft Free Download is off-line.
The ideas of "on-line" and "off-line" have been generalized from computing Warcraft Free Download and telecommunication into the field of Warcraft Free Download human interpersonal relationships. The distinction Warcraft Free Download between what Warcraft Free Download is considered "on-line" and 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 Warcraft Free Download distinction between computer-mediated communication and face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, and "off-line" is reality (e.g. real life or Warcraft Free Download meatspace). Slater states that this distinction is Warcraft Free Download "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 Warcraft Free Download people draw no distinction between an "on-line" Warcraft Free Download relationship, such as Warcraft Free Download indulging in cybersex, and an "off-line" relationship, such as Warcraft Free Download being pen-pals. He also Warcraft Free Download argues that Warcraft Free Download even Warcraft Free Download the telephone can be regarded Warcraft Free Download as an Rpgmaker2000 Game Download "on-line" experience in some 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 and voice-over-IP) has made it "impossible to use the term 'on-line' meaningfully Warcraft Free Download in the sense that was Warcraft Free Download employed by the first Warcraft Free Download generation of Internet research".[7]
Slater asserts that there are legal and Warcraft Free Download regulatory pressures to reduce the distinction between "on-line" Warcraft Free Download 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 to pre-existing off-line Warcraft Free Download relationships. He conjectures that greater legal status may be assigned to on-line Warcraft Free Download relationships (pointing Free Web Browsers Download out that contractual relationships, such as business transactions, Warcraft Free Download on-line Warcraft Free Download are already seen as just as "real" as their off-line Warcraft Free Download counterparts), although Warcraft Free Download he states it to be hard to imagine courts awarding palimony to people who have had a purely on-line sexual relationship. Warcraft Free Download He also conjectures 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 Warcraft Free Download seen as virtuality and "off-line" as Warcraft Free Download reality Warcraft Free Download is sometimes Warcraft Free Download inverted, Warcraft Free Download with "on-line" concepts Warcraft Free Download being used to define and Warcraft Free Download to explain "off-line" activities, rather than Warcraft Free Download (as per the conventions of the desktop metaphor with its desktops, trash cans, folders, and so forth) the other way around. Several Warcraft Free Download cartoons by The New Yorker have satirized this. One includes Saint Peter asking for a Warcraft Free Download user name and a password before admitting a man into Heaven. Another illustrates "the off-line store" where "All items Free Shareaza Download are actual size!", where shoppers may "Take it home as soon Warcraft Free Download as you pay Warcraft Free Download for Warcraft Free Download it!", and where "Merchandise may be handled prior to purchase!". |
