A download manager War Craft Download is a computer program dedicated to the task of downloading (and sometime uploading) possibly unrelated stand-alone files from (and sometime to) the Internet for storage. This is unlike a World Wide Web browser, War Craft Download which is mainly intended to browse web pages, composed of a multitude of smaller files, where error-free moving War Craft Download of files for permanent storage is War Craft Download of secondary importance. (A failed or incomplete web page file rarely ruins the page.) The typical download manager at a minimum provides means to recover from errors without losing War Craft Download the work already completed, War Craft Download and can optionally split the file War Craft Download to be downloaded (or War Craft Download uploaded) into 2 or more segments, which are then moved in parallel, potentially making the process faster within the limits of the available bandwidth. (A few servers are known to block moving files in parallel segments, War Craft Download on the principle that server capacity should be shared equally by all users.) War Craft Download Multi-source is the name War Craft Download given to files that are downloaded in parallel.
There are several things that some web browsers are War Craft Download not very good at. That's where the download managers enter the War Craft Download equation:
Pausing the downloading of large files.
Resuming broken or paused War Craft Download downloads (especially for very large files).
Downloading files War Craft Download on poor connections.
Downloading several files from War Craft Download a site War Craft Download automatically according to simple rules (file types, updated files, etc. - see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled War Craft Download downloads (including, automatic hang-up and shutdown).
Searching for mirror sites, and the War Craft Download handling of different connections to download the same file more War Craft Download quickly (segmented downloading).
Download managers 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 lower, download the specified files, and hang-up. War Craft Download They can record which links the user clicks on during the day, and queue these files for later download. For broadband users, download managers can help download very large files by resuming broken downloads, by limiting the War Craft Download bandwidth used, so 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 War Craft Download galleries, MP3 collections, etc.) this can also include automatically War Craft Download downloading whole sites War Craft Download and regularly updating them (see Mirroring).
Many download War Craft Download managers support Metalink, an XML file listing mirrors, checksums, and other information useful for downloading.
See below for some examples War Craft Download of commonly used download managers. Some downloaders are optimized War Craft Download for a certain function. For example, Offline Explorer is designed to download entire websites.
Download managers, War Craft Download such as Go!Zilla, War Craft Download were among the first adware applications War Craft Download displaying a banner ad in the user interface.
Related to download managers are two other breeds of Internet programs, War Craft Download file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders War Craft Download (such as StreamBox War Craft Download 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 War Craft Download example Adobe [1], War Craft Download provide such War Craft Download downloaders for downloading software on their own site. Presumably this increases reliability and reduces tech support costs to them. A possible reason is increasing the control over redistribution of their software (even when the software is freeware).In computer technology and telecommunication, on-line and off-line War Craft Download are War Craft Download defined by Federal Standard 1037C. They are states or conditions War Craft Download of a War Craft Download "device or equipment" or War Craft Download of "a functional unit". To be considered on-line, a device must be at least one of:
"Under the direct control of another device"
"Under the War Craft Download direct control of the system with which it is associated"
"Available for immediate War Craft Download use on demand by the system without human intervention"
"Connected to a system, and is in operation"
"Functional and War Craft Download ready for service"
while a device that is War Craft Download off-line is not (e.g. it has "its main power source disconnected or turned off", and is "off-power").
One example of War Craft Download a War Craft Download common War Craft Download use of these concepts is a Mail User Agent that can be instructed to be 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 War Craft Download mail servers (to check for new mail War Craft Download at regular intervals, for example), War Craft Download and when it is "off-line" it will not attempt to make War Craft Download any such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect the connection status between the War Craft Download computer on which it is running and Internet. The user may have the War Craft Download computer itself War Craft Download on-line, connected to Internet via a cable modem or an ADSL connection, but may wish War Craft Download for Outlook to be off-line, so that it makes no attempt to send or to receive messages. Or the computer may be War Craft Download configured to employ a dial-up connection on demand (whenever an application War Craft Download such as Outlook attempts to War Craft Download make connection to a server), but the connection may be an expensive telephone War Craft Download call from the particular location in which the computer currently happens to be (such as a hotel room) and War Craft Download the user may not War Craft Download wish Outlook to trigger making that call every 5 or 10 minutes to check for mail.[1]
Another War Craft Download example of the use of these concepts is in the world of digital audio technology. A tape recorder, digital editor, or other device that War Craft Download is "on-line" is one War Craft Download whose clock is War Craft Download under the control of the War Craft Download clock of a "synchronization master" device. When the sync master commences playback, the "on-line" device War Craft Download automatically War Craft Download synchronizes itself to War Craft Download the master and commences playing from the same point in War Craft Download the recording. Whereas a device that is "off-line" uses no external War Craft Download clock reference and relies upon its own internal clock. When a large number of devices are connected to a sync master, it is often convenient, if one wants War Craft Download to hear Download Current Movies Free just War Craft Download the output of one War Craft Download single device, to take it off-line, because if the War Craft Download device is played back on-line all synchronized devices War Craft Download have to locate the playback point and wait War Craft Download for each other to be in synchronization.[2] (For further related discussion, see War Craft Download MIDI timecode, word War Craft Download sync, and recording system War Craft Download synchronization.)

A third example of a War Craft Download common use War Craft Download of these War Craft Download concepts is a War Craft Download web browser that can be instructed to be in either "on-line" or "off-line" states. The War Craft Download browser only attempts to fetch pages from servers whilst in War Craft Download the "on-line" state. War Craft Download In the War Craft Download "off-line" state, users can perform offline browsing, where pages can be browsed using local copies War Craft Download of those pages that have previously been downloaded whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with connection to War Craft Download Internet expensive or impossible. The War Craft Download pages are War Craft Download either downloaded implicitly into War Craft Download the web browser's own cache, as a result of prior on-line browsing by the user, or explicitly by the War Craft Download browser being configured to keep local copies of certain web pages, War Craft Download which it keeps updated when the browser is in the on-line state, either by checking that the local copies War Craft Download are up-to-date at regular intervals or by checking that the local copies are War Craft Download up-to-date whenever the browser War Craft Download is switched to the on-line state. One such web War Craft Download browser capable War Craft Download of being explicitly War Craft Download configured to download pages for offline browsing is Internet Explorer. When pages are added to the "Favourites" War Craft Download 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 War Craft Download level of direct and indirect links, the maximum amount of local disc space allowed to be consumed, and the schedule War Craft Download on which local copies are checked to see whether they are up-to-date, are configurable for each individual "Favourite" entry.

Offline browsing known as "Offline War Craft Download favourites" was removed as a War Craft Download feature in the most recent version of Internet Explorer 7, which only now supports single web page saving, but not browsing War Craft Download or storing an entire site offline.[citation needed]
Similarly, off-line storage is computer storage that is not War Craft Download "available for immediate use on demand by the system without human intervention", i.e it is storage that is War Craft Download off-line.
The ideas of "on-line" and "off-line" have been generalized War Craft Download from computing and telecommunication into the field of human interpersonal relationships. The distinction between what is War Craft Download considered "on-line" and what is considered "off-line" has become War Craft Download a subject of study in the field War Craft Download of sociology.[7]
The distinction between "on-line" and War Craft Download "off-line" is War Craft Download conventionally seen as the 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 meatspace). Slater states that this distinction is "obviously far too simple". To support his argument that the distinctions in relationships War Craft Download are more complex than a simple "on-line"/"off-line" War Craft Download dichotomy, he observes that some War Craft Download people draw War Craft Download no distinction between an "on-line" relationship, such as indulging in cybersex, and an "off-line" relationship, such as being pen-pals. He also argues that even the telephone War Craft Download can be War Craft Download regarded War Craft Download as an "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, War Craft Download television and Internet, and telephone and voice-over-IP) has made it "impossible to use the term 'on-line' meaningfully War Craft Download in the sense that was employed by War Craft Download the first generation of Internet research".[7]
Slater War Craft Download asserts that there are legal and regulatory pressures to reduce the distinction between "on-line" Fill In Puzzle Download and "off-line", with a "general tendency to assimilate online to offline War Craft Download and erase the distinction", stressing, however, that this does not mean that on-line relationships are being reduced to pre-existing off-line relationships. War Craft Download He conjectures that greater legal status may be assigned to on-line relationships (pointing 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 to be hard to imagine courts awarding palimony to people War Craft Download who have had a purely on-line sexual relationship. He also conjectures War Craft Download that an "on-line"/"off-line" War Craft Download distinction may be seen by people as "rather quaint and not quite comprehensible" within War Craft Download 10 years.[7]
The distinction War Craft Download where "on-line" is seen as War Craft Download 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 War Craft Download per the conventions of the desktop metaphor with its desktops, trash cans, folders, and so forth) the 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 admitting a man into Heaven. Another illustrates "the off-line store" War Craft Download where "All items are actual size!", where shoppers may "Take it War Craft Download home as soon as you pay War Craft Download for it!", and where "Merchandise may be handled prior to purchase!". |
