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 Live Masenger Download Free is unlike a World Wide Web Live Masenger Download Free browser, which Live Masenger Download Free is mainly intended to browse web pages, Live Masenger Download Free composed of a multitude of Live Masenger Download Free smaller files, where error-free moving of files Live Masenger Download Free for permanent storage is of secondary importance. (A failed or incomplete Live Masenger Download Free web page Live Masenger Download Free file rarely Live Masenger Download Free ruins the Live Masenger Download Free page.) The typical download manager Live Masenger Download Free at a minimum provides means to recover from errors without losing the work already completed, and can Live Masenger Download Free optionally split the file to be downloaded (or uploaded) into Live Masenger Download Free 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 Live Masenger Download Free capacity Live Masenger Download Free should Live Masenger Download Free be shared equally by all users.) Live Masenger Download Free Multi-source is the name given Live Masenger Download Free to Live Masenger Download Free files that Live Masenger Download Free 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 Live Masenger Download Free downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor connections.
Downloading Live Masenger Download Free 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, Live Masenger Download Free automatic hang-up and shutdown).
Searching for mirror sites, and the handling of different connections to download the same file more quickly (segmented downloading).
Download managers are useful for active Live Masenger Download Free Internet users. For dial-up users, they can Live Masenger Download Free automatically dial the internet service provider at night, when Live Masenger Download Free rates or tariffs are usually lower, download the specified files, and hang-up. They can record which links the user clicks on Live Masenger Download Free during the day, and Live Masenger Download Free queue these files for Live Masenger Download Free later download. For broadband users, download managers Live Masenger Download Free can help download very large files Live Masenger Download Free by resuming broken downloads, by limiting the bandwidth used, so that other internet Live Masenger Download Free activities are not affected (slowed) and the server is not overloaded, or by automatically navigating Live Masenger Download Free a site and downloading pre-specified content Live Masenger Download Free (photo Live Masenger Download Free galleries, MP3 collections, etc.) this can also include automatically downloading whole sites 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 commonly Live Masenger Download Free used download managers. Some downloaders are optimized for a Live Masenger Download Free 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 Live Masenger Download Free the user interface.
Related to Live Masenger Download Free download managers are two other breeds of Live Masenger Download Free Internet Live Masenger Download Free programs, file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (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 Live Masenger Download Free instead. Some software companies, for example Adobe [1], provide such Live Masenger Download Free downloaders for downloading software on their own site. Presumably this increases reliability and reduces tech Live Masenger Download Free support costs to them. A possible reason is increasing the control Live Masenger Download Free over Live Masenger Download Free redistribution Live Masenger Download Free of 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 are states Mac Os Download or conditions 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 Live Masenger Download Free of another device"
"Under the direct control of the system with which it is associated"
"Available for immediate use on Live Masenger Download Free demand by the system without Live Masenger Download Free human Live Masenger Download Free 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 power source disconnected or turned off", and is "off-power").
One example of a common use of these Live Masenger Download Free concepts is a Mail User Agent Live Masenger Download Free that can be instructed to be in either "on-line" or "off-line" states. One such MUA Live Masenger Download Free is Live Masenger Download Free Microsoft Outlook. When it is "on-line" it will attempt to connect Live Masenger Download Free 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 Live Masenger Download Free reflect the connection status between the computer on which it is running and Internet. The user may have the Live Masenger Download Free computer itself on-line, connected to Internet via a cable modem or an ADSL Live Masenger Download Free connection, but may wish for Outlook to be off-line, so that it makes no attempt to send or to Live Masenger Download Free receive messages. Or the computer may be configured to employ a dial-up connection on demand (whenever an application Live Masenger Download Free such as Outlook attempts to make connection to a server), Live Masenger Download Free but the connection may be an expensive telephone call from the particular location in which Live Masenger Download Free the Live Masenger Download Free computer currently happens to be (such as a hotel room) and the user may not wish Outlook Live Masenger Download Free to trigger making that call every 5 or 10 Live Masenger Download Free minutes to check for mail.[1]
Another Live Masenger Download Free example of the use Live Masenger Download Free of these concepts is Live Masenger Download Free in the world of Live Masenger Download Free digital audio technology. A tape recorder, digital editor, or other device that is "on-line" is one whose clock is under the control Live Masenger Download Free of the Live Masenger Download Free clock of a Live Masenger Download Free "synchronization master" device. When the sync master commences playback, the "on-line" device automatically synchronizes itself to the master and commences playing from the same point in the recording. Whereas a device that is "off-line" Live Masenger Download Free uses no external clock reference and relies upon its own internal clock. When a large Live Masenger Download Free number of devices are connected to a sync master, it is often convenient, if one wants Live Masenger Download Free to hear just the output of one single device, to Live Masenger Download Free take it off-line, because if the device is played Live Masenger Download Free 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 recording system synchronization.)
A third example of a common use of these concepts is a web browser that can Live Masenger Download Free be instructed Live Masenger Download Free to be 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 Live Masenger Download Free can perform offline browsing, where pages can be Live Masenger Download Free browsed using local copies of those pages that have previously been downloaded Live Masenger Download Free whilst in the "on-line" state. This Xp Validation Crack Download can be useful when Live Masenger Download Free the computer itself is also off-line, with connection to 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 Live Masenger Download Free user, or explicitly by the browser being configured to keep local copies Live Masenger Download Free of certain web pages, which it keeps updated when the browser is Live Masenger Download Free in the on-line state, either by checking that the local copies are up-to-date Live Masenger Download Free at regular intervals or by checking that the local copies are up-to-date whenever the browser is Live Masenger Download Free switched to the on-line state. One Live Masenger Download Free 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 be marked for being made Live Masenger Download Free "available for offline browsing". Internet Explorer will download to local copies Live Masenger Download Free both the marked page and, optionally, all of the pages that it links Live Masenger Download Free to. In Internet Explorer version 6, the level of direct and indirect links, Live Masenger Download Free the maximum amount of local disc space allowed to be consumed, and the schedule on which local copies are Live Masenger Download Free checked to see whether they are up-to-date, are configurable for each individual "Favourite" entry.

Offline browsing known Live Masenger Download Free as "Offline favourites" was removed Live Masenger Download Free as Live Masenger Download Free a feature in the most recent version of Internet Explorer 7, which only now supports single Live Masenger Download Free web page saving, but Live Masenger Download Free not Live Masenger Download Free 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 the system Live Masenger Download Free without human intervention", i.e it is storage that is off-line.
The ideas of "on-line" and "off-line" have been generalized from computing and telecommunication into the field of Live Masenger Download Free human Live Masenger Download Free interpersonal relationships. The distinction between what Live Masenger Download Free is considered Live Masenger Download Free "on-line" and what is considered "off-line" has become a subject of study in the field of Live Masenger Download Free sociology.[7]
The distinction Live Masenger Download Free between "on-line" and "off-line" is conventionally Live Masenger Download Free seen as the distinction between computer-mediated communication and face-to-face Live Masenger Download Free communication Live Masenger Download Free (e.g. face time), respectively. "On-line" Live Masenger Download Free is virtuality, and Live Masenger Download Free "off-line" is reality (e.g. real life or meatspace). Slater states that this distinction Live Masenger Download Free is "obviously far too simple". To support his argument that the Live Masenger Download Free distinctions in relationships are more complex than a simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction Live Masenger Download Free between an "on-line" relationship, such as indulging in cybersex, and an Live Masenger Download Free "off-line" relationship, such as Live Masenger Download Free being pen-pals. He also Live Masenger Download Free argues that even the telephone can be regarded as an "on-line" experience in some circumstances, and that the blurring of the distinctions between the uses of Live Masenger Download Free various technologies (such as PDA and mobile telephone, television and Internet, Live Masenger Download Free and telephone and voice-over-IP) Live Masenger Download Free has made it "impossible to use the term 'on-line' meaningfully in the sense that was employed Live Masenger Download Free by the first generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures to reduce the Live Masenger Download Free distinction between "on-line" and "off-line", with a "general tendency to assimilate online Live Masenger Download Free to offline and erase the distinction", stressing, however, that this Live Masenger Download Free 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 business transactions, on-line Live Masenger Download Free are already seen as just as "real" Download Psx Iso as their off-line counterparts), although he states it to be hard to imagine courts awarding Live Masenger Download Free palimony Live Masenger Download Free to people who have had a purely on-line sexual relationship. He also conjectures Live Masenger Download Free that an "on-line"/"off-line" distinction Live Masenger Download Free may be seen by people as "rather quaint and Live Masenger Download Free not quite comprehensible" within 10 years.[7]
The distinction where "on-line" is Live Masenger Download Free seen as virtuality and "off-line" as reality is sometimes inverted, with Live Masenger Download Free "on-line" concepts being used to define and to explain "off-line" activities, Live Masenger Download Free rather than (as per the conventions of the desktop metaphor with its desktops, trash cans, folders, and so forth) the other Live Masenger Download Free 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 as soon as you Live Masenger Download Free pay for it!", and where "Merchandise may be Live Masenger Download Free handled Live Masenger Download Free prior to purchase!".
