A download manager 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 Tortoisesvn Download is 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 Tortoisesvn Download of files for permanent storage is of secondary importance. (A failed Tortoisesvn Download or Tortoisesvn Download incomplete web page file rarely ruins the page.) The Tortoisesvn Download typical download manager at a minimum provides means to recover from errors without losing the work already completed, and can optionally split the file to be downloaded (or uploaded) into Tortoisesvn Download 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 Tortoisesvn Download are known to block moving files in parallel segments, on the principle Tortoisesvn Download that server capacity should be shared equally by Tortoisesvn Download all users.) Multi-source is Tortoisesvn Download the name given to files that are downloaded in parallel.
There are several things that some web browsers are Tortoisesvn Download not very good at. That's where the download managers enter the equation:
Pausing the downloading of Tortoisesvn Download large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor connections.
Downloading Tortoisesvn Download several files from a site automatically according to Tortoisesvn Download simple Tortoisesvn Download rules (file types, updated files, etc. - see Princess Elfina Episode Download also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, automatic hang-up and Tortoisesvn Download shutdown).
Searching for mirror Tortoisesvn Download sites, and the handling Tortoisesvn Download of different connections to download the same file more quickly (segmented downloading).
Download managers are useful for Tortoisesvn Download active Internet users. For dial-up users, they Tortoisesvn Download can automatically dial the internet service provider at night, when rates or tariffs are usually lower, download the specified files, and hang-up. They can record which links the Tortoisesvn Download user clicks on during the day, Tortoisesvn Download and queue these files for later Tortoisesvn Download download. For broadband users, download managers Tortoisesvn Download can help download very large files by resuming broken Tortoisesvn Download downloads, by limiting Tortoisesvn Download the bandwidth used, so that other internet activities are not affected (slowed) and the server is Tortoisesvn Download not overloaded, or by automatically navigating Ephemeris Toolbox Download a site Tortoisesvn Download and downloading pre-specified content (photo galleries, MP3 collections, etc.) Tortoisesvn Download this can also include automatically Tortoisesvn Download downloading whole sites and regularly updating them (see Mirroring).
Many download managers Grandtheftauto Download support Metalink, an XML file listing mirrors, checksums, and other information useful for downloading.
See below for some examples Tortoisesvn Download of commonly used download Tortoisesvn Download managers. Some downloaders are optimized for a certain function. For example, Tortoisesvn Download Offline Explorer is designed to 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 Tortoisesvn Download of Tortoisesvn Download Internet programs, file-sharing peer-to-peer Tortoisesvn Download applications (Kazaa, eMule, BitTorrent, Gnutella) and stream Safeguard Easy Download recorders (such as StreamBox VCR).
While Tortoisesvn Download download managers Tortoisesvn Download are Tortoisesvn Download designed to Tortoisesvn Download give users greater control over Tortoisesvn Download downloads, some Tortoisesvn Download downloaders are created to give that control to content distributors instead. Some software companies, for example Adobe [1], Tortoisesvn Download provide such Tortoisesvn Download downloaders Tortoisesvn Download for downloading software on their own site. Presumably this increases reliability and reduces tech support costs Tortoisesvn Download to them. A possible reason is increasing the control over redistribution Tortoisesvn Download of their Tortoisesvn Download software Tortoisesvn Download (even when the software is freeware).In computer technology and telecommunication, on-line and off-line are defined by Federal Standard 1037C. They are states or Tortoisesvn Download conditions of a "device Tortoisesvn Download or equipment" or of "a functional unit". To be considered on-line, a device Tortoisesvn Download must Tortoisesvn Download be Srf File Download at least one of:
"Under Tortoisesvn Download the direct control of Tortoisesvn Download another device"
"Under the direct control of Tortoisesvn Download the system Tortoisesvn Download with which it is associated"
"Available for immediate use on demand by the system without human intervention"
"Connected to a system, and is in operation"
"Functional and ready for service"
while a device that is off-line is not Tortoisesvn Download (e.g. it has "its main power source disconnected or turned off", Tortoisesvn Download and is "off-power").
One example of a common use Tortoisesvn Download 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 Tortoisesvn Download connect to mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" it will not attempt Tortoisesvn Download to make any such connections. The "on-line" or Tortoisesvn Download "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 Internet Tortoisesvn Download via a Tortoisesvn Download cable modem or an ADSL connection, but may wish Tortoisesvn Download for Outlook to be off-line, so that it makes no attempt to send or to receive messages. Or the Tortoisesvn Download computer may be Tortoisesvn Download configured to employ Tortoisesvn Download a dial-up connection on demand (whenever an application such as Outlook attempts to make connection to a server), but the Tortoisesvn Download connection may be an expensive telephone call from Tortoisesvn Download the particular location Tortoisesvn Download in which the computer currently happens to be (such as a hotel room) and the user may not wish Outlook to trigger 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 Tortoisesvn Download of the clock of a "synchronization master" device. When the sync master commences Tortoisesvn Download playback, the "on-line" device Tortoisesvn Download automatically synchronizes itself to the master and commences playing from Tortoisesvn Download the same point in Download Evo2-sync the recording. Whereas a Tortoisesvn Download device that is "off-line" uses no Tortoisesvn Download external clock reference Tortoisesvn Download and relies upon its own internal clock. When a large number of devices are connected to a sync master, Tortoisesvn Download it is often convenient, Tortoisesvn Download if one wants to hear just the 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 playback point and wait for each other to be in synchronization.[2] (For further related discussion, see MIDI Tortoisesvn Download timecode, word sync, and recording system synchronization.)

A third Tortoisesvn Download example of a common use of these concepts is a web browser that can be instructed to Tortoisesvn Download be in either "on-line" or Tortoisesvn Download "off-line" states. The browser only attempts to fetch pages from servers whilst in the "on-line" state. In the "off-line" state, Tortoisesvn Download users can perform offline browsing, where pages can be Tortoisesvn Download browsed Tortoisesvn Download using local copies of those Tortoisesvn Download pages Tortoisesvn Download that have previously been Tortoisesvn Download downloaded whilst in the "on-line" state. This can be useful Tortoisesvn Download when the computer itself is also off-line, with connection to Tortoisesvn Download Internet expensive or impossible. The pages are either downloaded implicitly Tortoisesvn Download into the web Free Download Pcanywhere 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 checking that Tortoisesvn Download 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 Tortoisesvn Download the on-line state. One such web browser capable of being explicitly Tortoisesvn Download configured to download pages for offline Tortoisesvn Download browsing is Internet Explorer. When pages are added to Tortoisesvn Download the "Favourites" list, they can be marked for being made "available for offline browsing". Internet Explorer Tortoisesvn Download will download to local copies both the marked page and, optionally, all of the pages that it Tortoisesvn Download links to. In Internet Explorer version 6, the level of direct and indirect links, the maximum amount of local disc space allowed Tortoisesvn Download to be consumed, and the schedule on Tortoisesvn Download which local copies are checked Tortoisesvn Download to see whether they are up-to-date, are configurable for each individual "Favourite" entry.

Offline browsing known as Download Server Software Free "Offline favourites" was 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 entire site offline.[citation needed]
Similarly, off-line storage is computer storage that is not "available for immediate use on demand by Fruity Loops Program Download the system without human intervention", i.e it is storage that is off-line.
The ideas of "on-line" and "off-line" have been Tortoisesvn Download generalized from computing and telecommunication Tortoisesvn Download into the field of human interpersonal relationships. The distinction between what is considered "on-line" and what is considered "off-line" Tortoisesvn Download has become Tortoisesvn Download a subject of study Tortoisesvn Download 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), respectively. "On-line" is virtuality, and "off-line" is reality (e.g. real Tortoisesvn Download life or meatspace). Slater states Tortoisesvn Download that this distinction Tortoisesvn Download is "obviously Tortoisesvn Download far too simple". To Tortoisesvn Download support his argument that the distinctions in relationships are Tortoisesvn Download more Tortoisesvn Download complex than a simple "on-line"/"off-line" dichotomy, he observes that some people draw 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 Tortoisesvn Download even the telephone can be regarded as Tortoisesvn Download an "on-line" experience in Tortoisesvn Download some circumstances, and that the Tortoisesvn 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 'on-line' meaningfully in the sense that was employed by the first generation of Internet research".[7]
Slater asserts that Tortoisesvn Download there are legal and regulatory pressures to reduce the distinction between "on-line" and "off-line", with Tortoisesvn Download a "general tendency to assimilate Tortoisesvn Download online to offline and erase the distinction", stressing, Tortoisesvn Download however, that this does not mean that on-line relationships are being reduced to pre-existing off-line relationships. He conjectures that greater legal status may be assigned to on-line relationships (pointing out that contractual relationships, such as Tortoisesvn Download business transactions, on-line are already seen as just as "real" as their off-line counterparts), although he states it to be hard to Tortoisesvn Download imagine courts awarding palimony to people Tortoisesvn Download who have Tortoisesvn Download had Tortoisesvn Download a purely Tortoisesvn Download on-line sexual relationship. He also conjectures that an Tortoisesvn Download "on-line"/"off-line" distinction may be seen by people as "rather quaint and not quite Tortoisesvn Download 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 Tortoisesvn Download being used to define Tortoisesvn Download and to Tortoisesvn Download explain "off-line" activities, rather Tortoisesvn Download than (as per the conventions of the desktop metaphor with its desktops, trash Tortoisesvn Download cans, folders, and so forth) the other way around. Several cartoons by The New Tortoisesvn Download Yorker have satirized Tortoisesvn Download 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 items are actual size!", where shoppers may "Take it Tortoisesvn Download home as soon as you pay for it!", and where "Merchandise may be handled prior to purchase!". |
