A download manager is a computer program dedicated to Free Download Music Videos the task of downloading (and sometime uploading) possibly unrelated stand-alone files from Free Download Music Videos (and sometime Free Download Music Videos to) the Internet for storage. This Free Download Music Videos is unlike a World Wide Web browser, which is Free Download Music Videos mainly intended to browse Free Download Music Videos web pages, composed of a Free Download Music Videos 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 page.) The typical download manager at Free Download Music Videos a minimum provides means to recover from errors without losing the work already completed, and can Free Download Music Videos optionally split the Free Download Music Videos file to be downloaded (or 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, on the principle that server capacity should be shared equally by all users.) Multi-source is the name given to files that are downloaded in parallel.
There are several Free Download Music Videos things that some web browsers are not very good at. That's where the download Free Download Music Videos managers Free Download Music Videos enter Free Download Music Videos the equation:
Pausing the downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor Free Download Music Videos connections.
Downloading several files from a site 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 for mirror Free Download Music Videos sites, Free Download Music Videos and the handling of different connections to download the same file more quickly (segmented downloading).
Download managers are useful Free Download Music Videos for active Internet users. For Free Download Music Videos dial-up users, they can automatically dial the internet service provider at night, when rates Free Download Music Videos or tariffs are usually lower, download the specified files, and hang-up. They can record which Free Download Music Videos links Free Download Music Videos the user clicks on during the day, Free Download Music Videos and queue these files for later download. For broadband users, Free Download Music Videos 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 Free Download Music Videos (slowed) and the server is not overloaded, or by automatically Free Download Music Videos navigating a site and Free Download Music Videos downloading pre-specified Free Download Music Videos content (photo galleries, MP3 collections, etc.) this can also include automatically downloading whole sites and regularly updating Free Download Music Videos them (see Mirroring).
Many download managers support Metalink, an XML Free Download Music Videos file listing mirrors, Free Download Music Videos checksums, and other information useful for Free Download Music Videos downloading.
See below for some examples of commonly used download managers. Some downloaders Free Download Music Videos are optimized for a certain function. For example, Offline Explorer is designed to download entire websites.
Download managers, such as Go!Zilla, were among Free Download Music Videos the first adware applications displaying Free Download Music Videos a banner Free Download Music Videos ad in the Free Download Music Videos user interface.
Related to download managers are two other Free Download Music Videos breeds of Free Download Music Videos Internet programs, file-sharing peer-to-peer Free Download Music Videos applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such as StreamBox VCR).
While download Free Download Music Videos managers are designed to give users greater control over Free Download Music Videos downloads, some downloaders Free Download Music Videos are created to give that Free Download Music Videos control to content distributors instead. Some software companies, for example Adobe [1], provide such downloaders for downloading software on their Free Download Music Videos own site. Presumably this increases Free Download Music Videos reliability and reduces tech support costs to them. A possible reason is increasing the control over redistribution Free Download Music Videos of their software (even when the software is freeware).In computer technology and telecommunication, on-line and off-line are defined by Federal Free Download Music Videos Standard 1037C. They are states or conditions Free Download Music Videos of a "device or equipment" or 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 direct Free Download Music Videos control of the system with which it is associated"
"Available Free Download Music Videos 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 (e.g. it has "its main Free Download Music Videos power Free Download Music Videos source disconnected or Free Download Music Videos turned off", Free Download Music Videos and is "off-power").
One example of a common use of these concepts is Emule Plus Download a Mail User Agent that can Free Download Music Videos be instructed to be in either "on-line" or "off-line" states. One such MUA is Microsoft Free Download Music Videos Outlook. When it is "on-line" it will attempt to connect to mail servers (to check for new mail at regular intervals, for example), Picasa Download and when it is "off-line" it will not attempt to make any such connections. The "on-line" or "off-line" state of the Free Download Music Videos MUA Free Download Music Videos does not necessarily reflect the connection Free Download Music Videos status between the computer on which it Free Download Music Videos is running and Internet. The user may have the computer itself on-line, connected to Internet via a cable modem or an ADSL Free Download Music Videos connection, but may wish for Outlook Free Download Music Videos to be off-line, Free Download Music Videos so Free Download Music Videos that it makes no attempt to send or to receive messages. Or the computer may be configured to employ a dial-up connection on demand (whenever an application such Free Download Music Videos as Outlook attempts to make connection to a server), but the Free Download Music Videos connection may be an expensive telephone Free Download Music Videos call from the particular location in Free Download Music Videos which Download Full Free Linux the computer currently happens to be (such as Free Download Music Videos Download Internet a hotel room) and the user may not Free Download Music Videos 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 Free Download Music Videos in the world of digital audio technology. A tape recorder, digital editor, or other device that is "on-line" Free Download Music Videos is one whose clock Free Download Music Videos is under the Free Download Music Videos control of the clock of a "synchronization master" device. Free Download Music Videos When the Free Download Music Videos sync master commences playback, the "on-line" device automatically synchronizes itself to Free Download Music Videos the master and commences playing from the same point in Free Download Music Videos the recording. Whereas a device that is Free Download Music Videos "off-line" uses no Free Download Music Videos external clock reference and relies upon its own internal clock. When a Free Download Music Videos large number of devices are connected to a sync master, it is often convenient, if one Building Construction Excel Spreadsheet Download 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 timecode, word sync, and Free Download Music Videos recording system synchronization.)
A third example of Free Download Music Videos a Free Download Music Videos common use of these concepts Free Download Music Videos is a web browser that can be instructed to be Free Download Music Videos in either Free Download Music Videos "on-line" or "off-line" states. The Free Download Music Videos browser only attempts to fetch pages from servers whilst in the "on-line" state. In the "off-line" Free Download Music Videos state, users can perform Free Download Music Videos 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, Download Shake Down with connection to Internet expensive or impossible. The pages are either Free Download Music Videos 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 Free Download Music Videos Free Download Mp3 Song web Free Download Music Videos pages, which it keeps updated when the browser is in the on-line state, either by checking that the local copies are up-to-date at regular intervals Free Download Music Videos or by checking that the local copies are up-to-date whenever the browser is switched to the Free Download Music Videos on-line Free Download Music Videos state. One such web browser capable of being explicitly Free Download Music Videos configured to Free Download Music Videos download pages for Free Download Music Videos offline browsing Free Download Music Videos is Internet Explorer. When pages are Free Download Music Videos added to Free Download Music Videos the "Favourites" list, they can be marked for being made "available for offline browsing". Internet Explorer will download to local copies Free Download Music Videos both the marked page and, Free Download Music Videos optionally, all of Free Download Music Videos the pages that it links to. In Internet Explorer version Free Download Music Videos 6, the level of direct and indirect links, the Free Download Music Videos maximum amount of local disc Free Download Music Videos space allowed to be consumed, Free Download Music Videos and the schedule on which local Free Download Music Videos copies are Free Download Music Videos checked to see whether they are up-to-date, are configurable for Free Download Music Videos each individual "Favourite" Free Download Music Videos entry.

Offline browsing known as "Offline favourites" was removed as a Free Download Music Videos feature in the most recent version of Internet Download Vlc Player Explorer 7, which only now supports single web page saving, Free Download Music Videos but not Free Download Music Videos browsing or storing an entire site offline.[citation needed]
Similarly, off-line storage is computer storage that Free Download Music Videos is not "available for immediate use on demand by the system without human intervention", i.e it Free Download Music Videos is storage that is off-line.
The ideas of "on-line" and "off-line" have been generalized Pdf Download from computing and telecommunication into the field of human interpersonal relationships. The Free Download Music Videos distinction between what is considered "on-line" and what Free Download Music Videos is considered "off-line" has become Free Download Music Videos a subject of study Free Download Music Videos 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 life or meatspace). Slater states that this distinction is Free Download Music Videos "obviously far too simple". To support his argument that the distinctions in relationships are more 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 Free Download Music Videos in cybersex, and an "off-line" relationship, such as being pen-pals. He also argues that even the telephone can Free Download Music Videos be regarded as an "on-line" experience Free Download Music Videos in some circumstances, and that the blurring of Free Download Music Videos the distinctions between the Free Download Music Videos 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 Free Download Music Videos the sense that Free Download Music Videos was employed by the first generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures to reduce the distinction between "on-line" and "off-line", with a "general tendency to assimilate online Free Download Music Videos to offline and erase the distinction", stressing, however, that this does Free Download Music Videos not mean that on-line relationships are being reduced to pre-existing off-line relationships. He conjectures that greater Download Opera 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 Free Excel Download off-line counterparts), although he states it to be hard to imagine courts awarding palimony to people who have had a purely on-line sexual relationship. Free Download Music Videos He also conjectures that an "on-line"/"off-line" distinction may be seen Fire Fox Download by people as "rather quaint and not quite Free Download Music Videos comprehensible" within 10 years.[7]
The distinction where "on-line" is seen as virtuality and "off-line" as reality is sometimes Free Download Music Videos inverted, with Free Download Music Videos "on-line" concepts being used to define and to explain "off-line" activities, rather than (as per the conventions of the Free Download Music Videos desktop metaphor with its desktops, trash cans, folders, Free Download Music Videos 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" where "All items are actual size!", where shoppers may "Take it home Free Download Music Videos as soon as you pay for it!", and where "Merchandise may be handled prior to purchase!". |
