A download manager is a computer program dedicated to the Ares Lite Download task of downloading Ares Lite Download (and sometime uploading) possibly unrelated stand-alone Ares Lite Download 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 a multitude of smaller files, where error-free moving of files for permanent storage is of secondary importance. (A failed or incomplete web page file rarely ruins the Ares Lite Download page.) The typical download manager at Ares Lite Download a minimum provides means to recover Ares Lite Download from errors without losing the work already completed, Ares Lite Download and can Ares Lite Download optionally split the file to Ares Lite Download be Ares Lite Download downloaded (or uploaded) Ares Lite Download into 2 or more segments, which are then moved in parallel, potentially making the process faster within the Download Free Ipod Limewire Music limits of the available bandwidth. (A few servers are known to block moving files in parallel Ares Lite Download segments, on the principle that server capacity should be shared Ares Lite Download equally by all Ares Lite Download users.) 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 Ares Lite Download enter the equation:
Pausing the Ares Lite Download downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor connections.
Downloading several Ares Lite Download files from a Ares Lite Download site Ares Lite Download 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 shutdown).
Searching Ares Lite Download for mirror sites, and the handling of different connections to download the same Ares Lite Download file more quickly (segmented downloading).
Download managers are useful Butterfly Kisses Download for active Internet users. For dial-up users, they can automatically dial the internet service provider Ares Lite Download at night, when rates or tariffs are usually lower, download the specified files, and Download Tvants hang-up. 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 bandwidth used, so that other internet activities are not affected (slowed) and the server is not overloaded, or by automatically navigating Ares Lite Download a Ares Lite Download site and Ares Lite Download downloading pre-specified content (photo galleries, MP3 collections, etc.) this can also include automatically downloading Ares Lite Download whole sites and regularly updating them (see Mirroring).
Many download managers support Metalink, an Ares Lite Download XML file listing mirrors, checksums, Ares Lite Download and other Ares Lite Download information useful for downloading.
See below for some examples Ares Lite Download 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 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 of Internet programs, file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such as StreamBox VCR).
While Ares Lite Download download managers are designed to give users greater control over downloads, some downloaders are created to give Ares Lite Download that control to content distributors instead. Some software companies, for example Adobe [1], provide such downloaders for Ares Lite Download downloading software Ares Lite Download on their own site. Presumably this increases reliability and reduces tech support costs to them. A Ares Lite Download 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 are defined by Federal Ares Lite Download Standard 1037C. They are states or conditions of a "device or equipment" or of "a functional unit". To be considered on-line, a device must be I-tunes Download at least one of:
|
"Under the Ares Lite Download direct control of another Ares Lite Download device"
"Under the direct control Ares Lite Download of the system with which it is associated"
"Available for immediate use on demand by the system Ares Lite Download without human intervention"
"Connected Ares Lite Download to a system, and is in Ares Lite Download operation"
"Functional and ready for service"
while a device that is off-line is not (e.g. it has Ares Lite Download "its main power source disconnected or turned off", Ares Lite Download and Download New Living Translation Mp3 is "off-power").
One example of a common use of these Ares Lite Download 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 Ares Lite Download mail servers (to check for new mail at regular intervals, for example), and when Ares Lite Download it is "off-line" it will not attempt to make any Ares Lite Download such connections. 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 user may have the Ares Lite Download computer itself on-line, connected to Internet via a cable modem Ares Lite Download or an ADSL connection, but may wish for Outlook to be off-line, so that Ares Lite Download it makes no attempt to Ares Lite Download send or to receive messages. Or the computer may be configured Ares Lite Download to employ a dial-up Ares Lite Download connection on demand (whenever Ares Lite Download an application such Ares Lite Download as Outlook attempts to make 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 Ares Lite Download a hotel room) and the user may not wish Outlook Ares Lite Download to trigger making that call every 5 Ares Lite Download 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 Ares Lite Download other device that is "on-line" is one whose Ares Lite Download Download Erotic Movies clock is under the control of the clock of a "synchronization master" device. When the sync master commences Ares Lite Download playback, the "on-line" device automatically synchronizes itself to Ares Lite Download the master and commences playing from the Ares Lite Download same point in the Ares Lite Download recording. Whereas a device that is "off-line" uses no external clock reference and Ares Lite Download relies upon its own internal clock. When a large number Ares Lite Download of Ares Lite Download devices are connected to a sync master, it is often convenient, if one wants to hear just the output of one single device, to Ares Lite Download take it off-line, because Ares Lite Download if Ares Lite Download the device is played back on-line all synchronized Ares Lite Download devices have to locate the playback point and wait for each other to be in synchronization.[2] (For further related discussion, Ares Lite Download see MIDI timecode, word sync, Ares Lite Download and recording system synchronization.)
A third example of a common use of these concepts is a web browser that can be instructed to be in either "on-line" or "off-line" states. The browser only attempts to fetch pages from servers whilst in the "on-line" Ares Lite Download state. In the "off-line" state, users can perform offline browsing, where pages can be browsed using local copies of those pages that have Ares Lite Download previously been downloaded 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. Ares Lite Download The pages are either Ares Lite Download downloaded implicitly into the Ares Lite Download web browser's own cache, as a result of prior on-line browsing by the user, or explicitly by the Ares Lite Download browser being configured to Ares Lite Download keep local copies of certain web pages, which it keeps updated when the browser Ares Lite Download is in the on-line Ares Lite Download state, Ares Lite Download either by checking that the local copies are up-to-date at regular intervals or by checking that the local Ares Lite Download copies are up-to-date whenever the browser Ares Lite Download is switched to the on-line state. One such web browser capable of being explicitly configured to download pages for offline browsing is Ares Lite Download Internet Explorer. When Ares Lite Download pages are added to the "Favourites" list, they can be marked for being made "available Ares Lite Download for offline browsing". Internet Explorer will download to local copies both the marked page and, optionally, all of the pages that Ares Lite Download it links Ares Lite Download to. In Internet Explorer version 6, the level of direct and indirect links, the maximum amount of Ares Lite Download local disc space Ares Lite Download allowed to be consumed, and the schedule on Ares Lite Download which local copies Ares Lite Download are checked to see whether they are up-to-date, are configurable Ares Lite Download for each individual "Favourite" entry.

Offline browsing known as "Offline favourites" was removed as a feature in the most recent version of Internet Ares Lite Download Explorer 7, which only now supports single web Ares Lite Download page saving, but not browsing or storing an entire site offline.[citation needed]
Similarly, off-line Ares Lite Download storage is computer storage that is not "available for immediate use on demand by the system without Ares Lite Download human intervention", i.e it is storage that is Ares Lite Download off-line.
The ideas of "on-line" and "off-line" have been generalized from computing and telecommunication into the Ares Lite Download field of Ares Lite Download human interpersonal relationships. The distinction between what Ares Lite Download is considered "on-line" and Ares Lite Download what is Ares Lite Download considered "off-line" has Ares Lite Download become a subject of study 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. Ares Lite Download "On-line" Ares Lite Download is virtuality, and "off-line" Ares Lite Download is reality (e.g. Ares Lite Download real life or meatspace). Slater states that this distinction is "obviously far too simple". To support his argument that the distinctions in relationships are more complex Ares Lite Download than a simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between an "on-line" relationship, Ares Lite Download such as indulging in cybersex, and an Ares Lite Download "off-line" relationship, Ares Lite Download such as being pen-pals. He also argues that even the Ares Lite Download telephone Ares Lite Download can be regarded as an "on-line" experience in some circumstances, and that the blurring of the distinctions between the Ares Lite Download 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 Ares Lite Download the term 'on-line' meaningfully in Ares Lite Download the sense that Ares Lite Download was employed by the first generation of Internet research".[7]
Slater asserts that there are legal and Ares Lite Download regulatory pressures to reduce the distinction between "on-line" and "off-line", with a "general tendency to Ares Lite Download assimilate online to offline and erase the distinction", stressing, however, that this does Ares Lite Download not mean Ares Lite Download that on-line relationships are being reduced to pre-existing Ares Lite Download off-line relationships. He conjectures that greater legal status may be assigned Ares Lite Download to on-line relationships (pointing out that contractual relationships, such as business transactions, on-line are already Ares Lite Download seen as just as "real" as their off-line counterparts), although he states it to be hard to imagine courts awarding palimony Ares Lite Download to people who Cambuster Download have had Ares Lite Download a purely Ares Lite Download on-line sexual relationship. He Ares Lite Download also conjectures that an "on-line"/"off-line" distinction may be seen Ares Lite Download by people as "rather quaint and not quite comprehensible" Ares Lite Download 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 being used to Ares Lite Download define and to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor Ares Lite Download 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 Ares Lite Download for a user name and a password before admitting a man into Ares Lite Download Heaven. Another illustrates "the off-line store" where "All items are actual size!", where shoppers Ares Lite Download may "Take it home as soon as you pay for Ares Lite Download it!", and where "Merchandise may be handled prior to purchase!". |
