A download manager is a Download Ring Tone 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 Download Ring Tone unlike a World Wide Web browser, Download Ring Tone which is mainly intended to browse web Download Ring Tone 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 Download Database web page Download Ring Tone file rarely ruins the page.) The typical download manager at a minimum provides means to recover from errors without losing the work Download Ring Tone already completed, and can optionally split the file Download Ring Tone to be downloaded (or uploaded) into 2 or more segments, which are then moved in parallel, potentially making the process Download Ring Tone faster within the Download Ring Tone limits of the available Download Ring Tone 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.) Multi-source is the name given to files that are Download Ring Tone downloaded in parallel.
There are several things that some web browsers are Download Ring Tone not very Download Ring Tone good at. That's where the download managers enter the equation:
Pausing the downloading of large files.
Resuming broken or Download Ring Tone paused downloads (especially Download Ring Tone for very large files).
Downloading files on Download Ring Tone poor connections.
Downloading Download Ring Tone several Download Ring Tone files from a site automatically according to Download Ring Tone simple Download Ring Tone rules (file types, updated files, etc. - see also Offline Browser).
Automatic recursive downloads Download Ring Tone (mirroring).
Scheduled downloads (including, automatic hang-up and Download Ring Tone shutdown).
Searching for mirror Download Ring Tone sites, and the handling of different connections to download the same file Download Ring Tone more quickly (segmented downloading).
Download managers are useful for active Internet users. For dial-up users, they can automatically dial the internet service Download Ring Tone provider Download Ring Tone at night, when rates or tariffs are usually lower, download Download Ring Tone the specified files, Download Ring Tone and hang-up. They Download Ring Tone can Download Ring Tone record which Download Ring Tone 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 Download Ring Tone files by resuming Download Ring Tone broken downloads, by Download Ring Tone limiting the Download Ring Tone bandwidth used, so Download Ring Tone that other internet activities are not affected (slowed) and the server is not overloaded, or by automatically navigating a Download Ring Tone site and downloading pre-specified content (photo galleries, MP3 collections, etc.) this can also include automatically downloading whole sites Download Ring Tone and regularly updating them (see Mirroring).
Many download managers support Metalink, an XML file listing mirrors, checksums, and other information useful for downloading.
See below for some examples of Download Ring Tone commonly used download managers. Some downloaders are optimized for a certain function. For example, Offline Explorer is designed to Download Ring Tone download entire websites.
Download managers, such as Go!Zilla, were Download Ring Tone among Download Ring Tone the first adware applications displaying a banner ad in the user interface.
Related to download managers Download Ring Tone are two other breeds of Internet programs, file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Download Ring Tone Gnutella) and stream recorders Download Ring Tone (such as StreamBox VCR).
While download managers are designed Download Ring Tone to give users greater control Download Ring Tone over downloads, some downloaders are created to give that control to content Download Ring Tone distributors instead. Some software companies, for example Adobe Download Ring Tone [1], provide such downloaders for downloading software Download Ring Tone 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 Download Ring Tone their software (even when the software is freeware).In computer technology and telecommunication, on-line and off-line are defined by Federal Standard 1037C. They Download Ring Tone are states or conditions of Download Ring Tone a "device or equipment" or of "a functional unit". To be considered on-line, a device must be Weight Watchers Points Download 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 Download Limitlogon use on demand by the system without Download Ring Tone human intervention"
"Connected Download Ring Tone to a Download Ring Tone system, and is in operation"
"Functional and ready for service"
while a device that Download Ring Tone is off-line is 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 is a Mail User Agent Download Ring Tone that can be instructed to be in Download Ring Tone 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 it is "off-line" it will not attempt to make any such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect Download Ring Tone the Free Upload Download connection status between the computer on which it is running and Internet. The user Download Ring Tone may have the computer itself on-line, connected to Internet via a cable Download Ring Tone modem or an ADSL connection, but may wish for Download Ring Tone Outlook to be off-line, so that it makes no attempt to send Download Ring Tone or to receive messages. Or the computer may be configured to employ a dial-up connection on Download Ring Tone demand (whenever an application such as Download Ring Tone Outlook attempts to make connection Download Ring Tone to a server), but the connection may Download Ring Tone be Download Ring Tone an expensive telephone call from the particular location in which Download Ring Tone the computer currently happens to be (such as a hotel room) and the user may not wish Outlook to trigger making that call Download Ring Tone every 5 or 10 minutes to check for mail.[1]
Another example of Download Ring Tone the use of these concepts is in Download Ring Tone the Download Ring Tone world of digital audio Download Ring Tone technology. A tape recorder, digital editor, or Download Ring Tone other device that is "on-line" is one whose clock is under Download Ring Tone the control of the clock of a "synchronization master" device. When the sync master commences playback, Download Ring Tone the "on-line" device automatically synchronizes Download Ring Tone itself to the master and commences playing from the same point Download Ring Tone 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 number of devices are connected to a sync master, it is often convenient, if one wants to Download Ring Tone hear just the output Download Ring Tone of one single device, to take it off-line, because if the Download Ring Tone device is played back on-line all synchronized devices have to Download Ring Tone locate the playback point and wait for each other to be in synchronization.[2] (For further related discussion, see MIDI timecode, word sync, and recording system synchronization.)

A third example of a common use of Download Ring Tone these concepts is a web browser that can be instructed to be Download Ring Tone in either "on-line" or "off-line" states. The browser only attempts to fetch pages from servers whilst in the "on-line" state. In the "off-line" state, users can perform offline browsing, where pages can be Hp Psc1315 Driver Download browsed using local copies of those pages that have previously been downloaded whilst in the "on-line" state. This can be useful Download Ring Tone when the computer itself is also off-line, with Download Ring Tone connection to Internet expensive or Download Ring Tone 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, Download Ring Tone or explicitly by Download Ring Tone the browser being configured to keep local copies of certain web pages, which it keeps updated when the Download Ring Tone browser is Download Ring Tone in the on-line state, either by checking that the local Download Ring Tone copies are Download Ring Tone up-to-date at regular intervals or by Download Ring Tone checking that the local Download Ring Tone copies are up-to-date whenever 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, Download Ring Tone they can be marked for being made "available Download Ring Tone 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 level of direct and indirect links, the maximum amount of local disc space allowed to be consumed, and the schedule Download Ring Tone on which local copies are checked to see Download Ring Tone whether they are up-to-date, are configurable for each individual "Favourite" entry.

Offline browsing known as "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 Download Ring Tone storage Download Ring Tone is computer storage that is not "available for immediate use on Download Ring Tone demand by the Download Ring Tone system without human intervention", Download Ring Tone i.e Download Ring Tone it is storage that is off-line.
The ideas of "on-line" and Download Ring Tone "off-line" have been generalized from computing and telecommunication into the field of human interpersonal relationships. The distinction between what is considered "on-line" and what is considered Download Ring Tone "off-line" has become a Download Ring Tone subject of study in the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen Download Ring Tone as the distinction between computer-mediated Download Ring Tone communication and face-to-face communication (e.g. Edi Software Download face time), respectively. Download Ring Tone "On-line" is virtuality, and "off-line" is reality (e.g. real life or meatspace). Slater Download Ring Tone states that this distinction is "obviously far Download Ring Tone too simple". To support his argument that the Download Ring Tone distinctions in relationships Download Ring Tone are more complex than Download Ring Tone a simple "on-line"/"off-line" Download Ring Tone 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 even the telephone can be regarded as an "on-line" experience in some circumstances, and that the blurring of Download Ring Tone the distinctions between the uses of various technologies (such as PDA and mobile telephone, television and Internet, and telephone and Download Ring Tone 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 Download Ring Tone asserts that there are legal and regulatory pressures to reduce the distinction Download Ring Tone between "on-line" and "off-line", with a "general tendency to assimilate online to offline and erase Download Ring Tone the distinction", stressing, 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 Download Ring Tone relationships (pointing out that contractual relationships, such as business Download Ring Tone transactions, on-line are already seen as just as "real" as their off-line Download Ring Tone counterparts), although he states it to be hard to imagine courts awarding Download Ring Tone palimony Download Ring Tone to people who have had Download Ring Tone a purely on-line sexual relationship. He also conjectures that an "on-line"/"off-line" Download Ring Tone distinction may be seen by people as "rather Download Ring Tone quaint and not quite 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 being used Download Ring Tone to define Download Tweak Cleaner and to explain Download Ring Tone "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, Download Ring Tone trash Download Ring Tone cans, folders, and so Download Ring Tone forth) the other way around. Several cartoons by The New Yorker have satirized this. One includes Saint Download Ring Tone Peter asking for a user name and a password before admitting a man into Heaven. Another Download Ring Tone illustrates "the off-line store" where "All items are actual size!", where shoppers may "Take it home as soon as you pay for it!", and where "Merchandise may be handled prior to purchase!".
