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 Download Vlc Player 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 Download Vlc Player is of secondary importance. (A failed or incomplete web page file Download Vlc Player rarely ruins the page.) The typical download manager at a minimum provides means to recover Download Vlc Player from errors without losing the work Download Vlc Player already completed, and can optionally split the 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 Download Vlc Player to block moving files in parallel segments, Download Vlc Player on the principle that server capacity should be shared Download Vlc Player equally by all users.) Multi-source Download Vlc Player is the name given Download Vlc Player to files Download Vlc Player that are Download Vlc Player 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 downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor connections.
Downloading Download Vlc Player several files from a site Download Vlc Player automatically according to simple rules (file types, updated files, etc. - see also Download Vlc Player Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads Download Vlc Player (including, automatic hang-up and shutdown).
Searching for mirror sites, and the handling of different connections to download Download Vlc Player the same file more quickly (segmented downloading).
Download managers are useful for active Internet users. For Download Vlc Player dial-up Download Vlc Player users, they can automatically dial the internet service provider at night, when rates or tariffs are Download Vlc Player usually lower, download the specified files, and hang-up. Download Vlc Player They can record which links the Download Vlc Player Download Episode Free Simpsons user clicks on during the Download Vlc Player day, and queue these files for later download. For broadband users, download managers can help High School Musical Download Free download very large files Download Vlc Player by resuming broken downloads, by limiting the bandwidth used, so that other internet activities are not Download Vlc Player affected (slowed) and the server is Download Vlc Player not Download Vlc Player overloaded, or by automatically navigating a site and downloading Download Vlc Player pre-specified content (photo galleries, MP3 collections, etc.) this can also include automatically Download Vlc Player downloading whole sites and regularly updating them (see Mirroring).
Many download managers support Metalink, an XML file listing mirrors, Download Vlc Player checksums, and other information useful for downloading.
See below for some examples of commonly used download managers. Some downloaders are optimized for a certain function. Download Vlc Player 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 Download Vlc Player other Download Vlc Player breeds of Internet programs, file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such as StreamBox VCR).
While download managers are Download Vlc Player designed to give users greater control over downloads, some downloaders are Download Vlc Player created to give Download Vlc Player that control to content distributors instead. Some software companies, for example Adobe [1], provide such downloaders for downloading software on their own Download Vlc Player site. Presumably this increases Download Vlc Player reliability and reduces tech support costs to them. A Download Vlc Player possible reason Download Vlc Player 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 Download Vlc Player defined by Federal Standard 1037C. They are states or Download Vlc Player conditions of a "device or equipment" Download Vlc Player or of "a functional unit". To be considered on-line, a device must be at least one of:
"Under Download Vlc Player the direct control of another device"
"Under the direct control Download Vlc Player of the system with which it Download Vlc Player 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 Download Vlc Player 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 concepts is a Mail User Emule Plus Download Agent that can be instructed to Download Vlc Player be in Download Vlc Player either "on-line" or "off-line" states. One such Download Vlc Player MUA is Microsoft Outlook. When it is "on-line" it will attempt Download Vlc Player to connect to mail Download Vlc Player 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 Vlc Player the connection status between the computer on which it Download Vlc Player is running and Internet. The user may have the computer itself on-line, connected to Internet via a cable modem or an ADSL connection, but may wish for Outlook to be off-line, Download Vlc Player so that it makes no attempt Download Vlc Player to send or to receive messages. Download Vlc Player Or the computer may be configured to employ Download Vlc Player a dial-up connection on demand (whenever Download Vlc Player an application such as Outlook attempts to make connection to a server), Download Vlc Player but the connection may Download Vlc Player be an expensive telephone call from the particular location in which the computer currently happens to be (such as a hotel room) and the user may not wish Outlook Download Vlc Player to trigger Download Vlc Player making that call every Download Vlc Player 5 or 10 minutes to check for mail.[1]
Another example of the use of these concepts is in the Download Vlc Player world of digital audio technology. A tape recorder, digital editor, or Download Vlc Player 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 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" uses no Download Vlc Player external clock reference and relies Download Vlc Player upon its own internal clock. Download Vlc Player When a large number of devices Download Vlc Player are connected Download Vlc Player to a sync master, it is often convenient, if one wants to Download Vlc Player hear just the output of one single device, to take it off-line, because Download Vlc Player if the device is Download Vlc Player 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 Download Vlc Player related discussion, Download Vlc Player see MIDI timecode, Download Vlc Player word Download Vlc Player sync, and Download Vlc Player 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 Download Vlc Player "on-line" or "off-line" states. The browser only attempts to fetch pages Download Vlc Player from servers whilst in the "on-line" state. In the "off-line" state, users can Download Vlc Player perform offline browsing, where pages Download Vlc Player can be browsed using local copies of those pages that have previously Download Vlc Player 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. The pages are either downloaded Download Vlc Player implicitly into the Download Vlc Player web browser's own cache, as a result Download Vlc Player of prior on-line browsing by the user, Download Vlc Player or explicitly by the browser being configured to keep local copies of certain web pages, which it keeps updated when the browser is in the Download Vlc Player on-line state, either by checking that the local copies are up-to-date at regular intervals or by checking that the local copies are up-to-date whenever the browser is switched to the Download Vlc Player on-line state. One such web browser capable of being explicitly configured to Download Vlc Player download pages for Download Vlc Player offline browsing is Internet Explorer. When pages are added to the "Favourites" list, they can be marked for being made "available for offline browsing". Internet Download Vlc Player Explorer will download to local copies both the Download Vlc Player marked page and, optionally, all of Picasa Download the pages that it links to. In Internet Explorer version 6, the level of direct and indirect links, Download Full Free Linux the maximum amount of local disc space allowed to be consumed, and the schedule Download Vlc Player on which local copies are checked to see whether they are Download Vlc Player 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 Download Vlc Player web page saving, but not browsing or storing an entire site offline.[citation needed]
Similarly, off-line Download Vlc Player storage is computer storage that is not "available for immediate use on demand by the system without human intervention", i.e it is storage that is off-line.
The ideas Download Vlc Player of "on-line" and "off-line" have been generalized from computing and telecommunication into Download Vlc Player the field of human interpersonal Download Internet relationships. The distinction Download Vlc Player between what is considered "on-line" and what is considered "off-line" has become a subject of study in the field of sociology.[7]
The distinction Download Vlc Player 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 Download Vlc Player meatspace). Slater states that this distinction is "obviously Download Vlc Player far too simple". To support his argument that the distinctions in relationships are more complex than Download Vlc Player a simple Download Vlc Player "on-line"/"off-line" 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 Download Vlc Player pen-pals. He also Download Vlc Player argues Download Vlc Player 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 various technologies (such as PDA and mobile telephone, Download Vlc Player television and Internet, and Download Vlc Player telephone and voice-over-IP) has made it "impossible to use the term 'on-line' meaningfully in the sense that was Download Vlc Player employed by Download Vlc Player the first generation of Internet research".[7]
Slater asserts that there Download Vlc Player are legal and regulatory pressures to reduce the distinction between "on-line" and "off-line", with a "general tendency Download Vlc Player to assimilate online Download Vlc Player to offline and erase the distinction", stressing, however, that this does not mean that on-line relationships are being reduced to pre-existing off-line relationships. Download Vlc Player He Download Vlc Player conjectures that greater legal status may be assigned to on-line relationships (pointing out that Download Vlc Player contractual relationships, such as business Download Vlc Player transactions, on-line Download Vlc Player are already seen as just as "real" as their Download Vlc Player off-line counterparts), although Download Vlc Player he states it to be hard to imagine Download Vlc Player courts Download Vlc Player Building Construction Excel Spreadsheet Download awarding 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 Vlc Player where "on-line" is seen Download Vlc Player as virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used to define Download Vlc Player and to explain "off-line" activities, Download Vlc Player rather than (as per Download Vlc Player the conventions of the desktop metaphor with its desktops, trash Download Vlc Player cans, folders, and so forth) the other way around. Several cartoons by The New Yorker have satirized this. One includes Saint Peter Download Shake Down asking for a Download Vlc Player user Download Vlc Player name and a password before admitting a man Download Vlc Player into Heaven. Another illustrates "the off-line Download Vlc Player store" Free Download Mp3 Song where "All items are actual size!", Download Vlc Player where shoppers may "Take it Download Vlc Player home as soon as you pay for Download Vlc Player it!", and where "Merchandise may be handled Download Vlc Player prior to purchase!". |
