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 is unlike a World Wide Web browser, which is mainly intended to browse web pages, composed of Download Rawr Files a Download Rawr Files multitude of smaller files, where error-free moving of files for permanent storage is of secondary importance. Download Rawr Files (A failed or incomplete web page file rarely ruins the Download Rawr Files page.) The typical download manager at a minimum provides means to recover from errors without losing the work Download Rawr Files already completed, and can optionally Download Rawr Files split the file to be downloaded (or uploaded) into 2 or more segments, which are then moved in parallel, potentially making the process Download Rawr Files faster within the Download Rawr Files limits of the available bandwidth. (A few servers are known to block moving files in parallel segments, on the principle that server capacity should be shared equally by all users.) Download Rawr Files Multi-source is the name given to files that are downloaded in parallel.
There are several things that some web browsers are not very good at. That's where the download managers enter the equation:
Pausing the Download Rawr Files downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor connections.
Downloading several files from Download Rawr Files a site automatically according to simple rules Download Rawr Files (file Download Rawr Files types, Download Rawr Files updated files, etc. - Download Rawr Files see also Offline Browser).
Automatic Download Rawr Files recursive downloads (mirroring).
Scheduled downloads (including, automatic hang-up and shutdown).
Searching for mirror sites, and Download Rawr Files the handling of different connections to download the Download Rawr Files same file more quickly (segmented downloading).
Download managers are Download Rawr Files useful Download Rawr Files for active Internet I Am Killing Heidi Download 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. They can record which links the user clicks on during the Download Rawr Files day, and queue these files Download Rawr Files for later download. For broadband users, Download Rawr Files download managers can help download very large files by resuming broken downloads, by limiting the 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 Download Rawr Files content (photo galleries, MP3 collections, etc.) this can also include automatically downloading whole sites Download Rawr Files and regularly Download Rawr Files updating them (see Mirroring).
Many download Download Rawr Files managers support Metalink, an XML file listing mirrors, checksums, and other information useful for downloading.
See below for some Download Rawr Files examples of commonly used download managers. Some downloaders are optimized for a certain function. For example, Offline Explorer is designed to download entire websites.
Download managers, such Download Rawr Files Gsxr Manual Download as Go!Zilla, were among the first adware applications Download Rawr Files displaying Download Rawr Files a banner ad in the user Download Rawr Files interface.
Related to download managers are two other breeds of Internet Download Rawr Files programs, file-sharing Download Rawr Files peer-to-peer applications Download Rawr Files (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders Download Rawr Files (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. Some software companies, for example Adobe Download Rawr Files [1], provide such downloaders Download Rawr Files for downloading software on Download Rawr Files 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 Download Rawr Files software is freeware).In computer technology and telecommunication, Download Rawr Files on-line and off-line are Download Rawr Files defined by Federal Standard Download Rawr Files 1037C. They are states or conditions of a "device or equipment" or of "a functional unit". To be considered on-line, a device must Download Rawr Files be at least one of:
"Under the direct control of another device"
"Under the direct Download Rawr Files 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 operation"
"Functional and ready for service"
while a device that is off-line is Download Rawr Files 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 Download Rawr Files is a Mail User Agent that can be instructed to be in either "on-line" or "off-line" states. Download Rawr Files One such MUA is Microsoft Outlook. When it is "on-line" Download Rawr Files it will attempt to connect to mail servers (to check for new mail at regular intervals, Download Rawr Files for example), and when it is "off-line" it will not attempt to Download Rawr Files make Download Rawr Files any such Download Rawr Files connections. The "on-line" or "off-line" state of Download Rawr Files the MUA does not necessarily reflect Download Rawr Files the Download Rawr Files connection status between the computer on which it is running and Internet. The user may have the computer itself on-line, connected to Internet via a cable modem or an Download Rawr Files ADSL connection, but Download Rawr Files may wish for Outlook to be off-line, so that it makes no attempt to Download Rawr Files send or Download Rawr Files to receive messages. Or the computer may Download Rawr Files be configured to Download Rawr Files employ a dial-up Download Rawr Files connection on demand (whenever an application such as Outlook attempts to make connection to a server), but the connection may be an expensive telephone call Download Rawr Files from the particular Download Rawr Files location in which Download Rawr Files the computer currently happens to be (such as Download Rawr Files a hotel room) and Download Rawr Files the user may not wish Outlook to trigger Download Rawr Files making that call every Download Rawr Files 5 or 10 Download Rawr Files minutes to check for mail.[1]
Another Download Rawr Files 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 clock of a "synchronization master" device. When the sync Download Rawr Files master Download Rawr Files commences playback, the "on-line" device automatically synchronizes itself to the master and commences playing from the same point Download Rawr Files in the recording. Whereas a device that is "off-line" uses no external clock reference and relies upon its own internal clock. When a large Download Rawr Files number of devices are connected to a sync master, it is often Download Rawr Files convenient, if one wants to hear just the output of one single device, to take it off-line, because if Dragonslair Download the device is played back Download Rawr Files on-line all synchronized devices have to locate the playback point and wait for each other to be in Download Rawr Files synchronization.[2] (For further related discussion, Download Rawr Files see MIDI timecode, word sync, and recording system synchronization.)
A third example of a common Celebrity Jeopardy Download Free use of these concepts is a web browser that can be instructed to be in either "on-line" or "off-line" states. The browser Opera Portable Download only attempts to fetch pages Download Rawr Files 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 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 Download Rawr Files 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 Download Rawr Files keeps updated when the browser is in Download Rawr Files the Download Rawr Files on-line state, either by checking that the local copies are up-to-date at Download Rawr Files regular intervals or by checking that Download Rawr Files the local copies are up-to-date whenever Download Rawr Files the browser is switched to the on-line state. One such web browser capable of being explicitly configured to download pages for offline browsing is Internet Explorer. When pages are added to the "Favourites" list, they can Download Rawr Files be marked for being made "available for offline Download Rawr Files browsing". Download Rawr Files Internet Explorer will download to local Download Rawr Files copies both the marked page and, optionally, all Download Rawr Files of the pages that it links to. In Internet Explorer version 6, the Download Rawr Files level of direct and indirect links, the maximum amount of local disc space allowed to be consumed, Download Rawr Files and the schedule on which local copies are checked to see whether they are up-to-date, are Download Rawr Files configurable for each individual "Favourite" entry.

Offline browsing known as "Offline Download Rawr Files favourites" was removed as a Download Rawr Files feature in the most recent version of Internet Download Rawr Files Explorer 7, which only now supports single web page saving, but not browsing or storing an entire Download Rawr Files site offline.[citation needed]
Similarly, off-line storage is computer storage Download Rawr Files that is not "available for immediate use on Loan Payment Tracking Download demand Download Rawr Files by the system without human intervention", i.e it is storage Download Rawr Files that is off-line.
The Download Rawr Files ideas of "on-line" and "off-line" have been generalized from computing Download Rawr Files and telecommunication into the field Download Rawr Files of human interpersonal relationships. The distinction between what is considered "on-line" and what is Download Rawr Files considered "off-line" has become a subject of study in the field of sociology.[7]
The distinction between "on-line" Download Rawr Files and "off-line" is conventionally seen as the distinction between computer-mediated communication and face-to-face Download Rawr Files 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 Download Rawr Files that the distinctions in Download Rawr Files relationships are more complex than Download Rawr Files a simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between Download Rawr Files an "on-line" relationship, such Usa Map Download as Download Rawr Files indulging in cybersex, and an "off-line" relationship, such as being pen-pals. He also argues Download Rawr Files that even the telephone can be regarded as an "on-line" experience in some circumstances, and that the blurring of the distinctions between the Download Rawr Files 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 Download Rawr Files that was employed by the first Download Rawr Files generation of Internet research".[7]
Slater asserts that there are legal and Download Rawr Files regulatory pressures to reduce the distinction Download Laputa Songs between "on-line" and "off-line", with a Albuns Download Blogspot Beyonce Collection "general tendency to Download Rawr Files assimilate online to offline and erase the distinction", stressing, however, that this does Download Rawr Files not mean that on-line relationships are being reduced to pre-existing Download Rawr Files off-line relationships. He Download Rawr Files 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 Download Rawr Files hard to imagine courts awarding Download Rawr Files palimony to people who have had a purely on-line sexual relationship. 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 Download Rawr Files where "on-line" is seen as virtuality and Download Rawr Files "off-line" as reality is sometimes inverted, with "on-line" concepts being used to define and to explain Download Rawr Files "off-line" activities, rather than (as per the conventions of Download Rawr Files the desktop Download Rawr Files metaphor with its desktops, trash Download Rawr Files cans, folders, and so forth) Download Rawr Files the Download Rawr Files other way around. Several cartoons by The New Yorker have satirized this. One Download Rawr includes Saint Peter asking Download Rawr Files for a user name and a password before admitting a Download Rawr Files man Download Rawr Files into Download Rawr Files Heaven. Another Download Rawr Files illustrates "the off-line store" where Download Rawr Files "All items are actual size!", where shoppers may "Take it home as soon as you pay for it!", and where Download Rawr Files "Merchandise may be handled prior to purchase!". |
