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 Windows Media Download unlike a World Wide Web browser, which is mainly intended Windows Media Download to browse web pages, Windows Media Download composed of a multitude of smaller files, where error-free Windows Media Download moving of files for permanent storage is of Windows Media Download secondary importance. (A failed or incomplete web page file rarely ruins the page.) The typical download manager at a minimum provides means to recover from Windows Media Download errors without losing Windows Media Download the work Windows Media Download already Windows Media Download completed, and Windows Media Download 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 Windows Media Download 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 Windows Media Download the name Windows Media Download given to files that are downloaded in parallel.
There are Windows Media Download several things that some web Windows Media Download browsers are not very good at. That's where the download Windows Media 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 several files from a site automatically according to Windows Media Download simple rules Windows Media Download (file Windows Media Download types, updated files, Windows Media Download etc. - Windows Media Download see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads Windows Media Download (including, automatic hang-up and shutdown).
Searching for mirror sites, and the handling of different connections Windows Media Download to download Windows Media Download the Windows Media Download same file more quickly (segmented downloading).
Download managers are useful for active Internet users. For dial-up Windows Media Download users, they can automatically dial the internet service provider at night, when Windows Media Download rates or tariffs Windows Media Download are usually lower, download the specified files, and 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 Windows Media Download by resuming broken downloads, by limiting the bandwidth used, so that other Windows Media Download internet Windows Media Download activities are not affected (slowed) and the server is not Windows Media Download overloaded, or by automatically Windows Media Download navigating a site and downloading pre-specified content Windows Media Download (photo galleries, MP3 collections, Windows Media Download etc.) this can also include automatically downloading whole sites and regularly updating them (see Mirroring).
Many download managers support Windows Media Download Metalink, an XML file listing mirrors, checksums, and other information useful for downloading.
See below for some examples of commonly used download managers. Some downloaders are optimized for a certain Windows Media Download function. For example, Windows Media Download Offline Explorer is designed to download entire websites.
Download managers, such as Go!Zilla, were Windows Media Download among the first adware applications Windows Media Download displaying a banner ad in the user interface.
Related Windows Media Download to download Windows Media Download managers are two Windows Media Download other breeds of Internet programs, file-sharing Windows Media Download peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders Windows Media Download (such as StreamBox Windows Media Download VCR).
While download managers are designed to give users greater control over downloads, some downloaders are created to give that control to content distributors instead. Some software companies, for example Adobe [1], provide such downloaders for downloading software on Windows Media Download their own site. Presumably this increases reliability and reduces tech support costs Windows Media Download to them. A possible reason is increasing Windows Media Download the control over redistribution of their software (even when the software is freeware).In computer technology and telecommunication, on-line and Windows Media Download off-line are defined by Federal Standard 1037C. They are states or conditions of a "device or equipment" Windows Media Download or of "a Windows Media Download functional unit". To be considered on-line, Windows Media Download a device must be at least one of:
"Under the direct control of another device"
"Under Windows Media Download the direct control of the system Windows Media Download with which it is associated"
"Available for immediate use Windows Media Download on demand by the system without human intervention"
"Connected to a system, and is in operation"
"Functional and Windows Media Download ready for Windows Media Download service"
while a Windows Media Download device that is Windows Media Download off-line is Windows Media Download not (e.g. it has "its main power source Windows Media Download disconnected or turned off", and Windows Media Download is "off-power").
One example of a common use of these 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 Windows Media Download to connect to mail servers (to check for Windows Media Download new Windows Media Download mail at regular intervals, for example), and when it is "off-line" it will not attempt to Windows Media Download make any such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect the connection Windows Media Download status between the computer on which it is running and Internet. The user may have the computer itself on-line, connected to Internet via a cable modem or an ADSL Windows Media Download connection, but may wish for Windows Media Download Outlook to be off-line, Windows Media Download so that it makes no Windows Media Download 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 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 a hotel room) and the user may not wish Outlook to trigger making that call every 5 or 10 minutes Windows Media Download to Mac Os Download check for mail.[1]
Another example of the use of these concepts is Windows Media Download in the world of digital Windows Media Download audio technology. A tape recorder, digital editor, or other device that is "on-line" is one whose clock is under the control of the clock of a "synchronization master" device. Windows Media Download 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 external clock Windows Media Download reference and Windows Media Download relies upon its own internal Windows Media Download clock. When a large number of devices are connected to a sync master, it is often convenient, if one wants to hear just the output of one single device, Windows Media Download to Windows Media Download take it off-line, because if the Windows Media Download device is played back on-line all Windows Media Download synchronized devices Windows Media Download have to locate the Windows Media Download playback Windows Media Download 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 be instructed to be in Windows Media Download either "on-line" or "off-line" states. The browser only attempts to Windows Media Download fetch pages from servers whilst in the "on-line" state. In the "off-line" state, users can perform 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 Windows Media Download 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 Windows Media Download by the Windows Media Download user, or explicitly by the browser being configured to keep local copies of certain web pages, which Windows Media Download it keeps updated when the browser is in Windows Media Download the on-line state, either by checking that the local copies are up-to-date at regular intervals or by checking that Windows Media Download the local copies are up-to-date whenever Windows Media Download the browser is switched Windows Media Download to the on-line state. One such web browser capable of being explicitly configured to download pages for offline Windows Media Download browsing is Internet Windows Media Download Explorer. Windows Media Download When pages are added to the "Favourites" list, they can be marked for being made "available for offline Windows Media Download browsing". Internet Explorer will download to local copies both the Windows Media Download marked page and, Windows Media Download optionally, all of the pages that Windows Media Download it links to. In Internet Explorer version 6, the level of direct Windows Media Download and indirect links, the maximum amount of Windows Media Download local disc space Windows Media Download allowed to be consumed, and the schedule on which local copies are checked to see whether Windows Media Download they are up-to-date, are configurable for each individual Xp Validation Crack Download "Favourite" entry.

Offline browsing known as "Offline Windows Media Download favourites" was removed as a feature in the most recent Windows Media Download version of Internet Explorer 7, which only now supports single web page saving, Windows Media Download but not browsing Windows Media Download 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 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 Windows Media Download and telecommunication into the field of human interpersonal relationships. The Windows Media Download distinction between what is considered "on-line" and what is considered "off-line" Windows Media Download has Download Psx Iso become a subject of study in the field of sociology.[7]
The Windows Media Download 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, Windows Media Download and "off-line" is reality (e.g. Windows Media 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 than a simple "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 pen-pals. He also argues that even the telephone can be regarded as an "on-line" Windows Media Download experience in some circumstances, and that the blurring of the Windows Media Download distinctions Windows Media Download between the 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 the sense that Windows Media Download was employed by the first generation Windows Media Download of Internet research".[7]
Slater Windows Media Download 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 to offline and erase the distinction", stressing, however, that this does Windows Media Download not mean that Windows Media Download 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 Windows Media Download out Windows Media Download that contractual relationships, such as business transactions, on-line are Windows Media Download already seen as just as "real" as their off-line counterparts), although he states Windows Media Download it to be hard to imagine courts awarding palimony to people who have had a Windows Media Download purely Windows Media Download on-line sexual relationship. He also conjectures that an "on-line"/"off-line" distinction may be seen Windows Media Download by people as "rather quaint and not quite comprehensible" Windows Media Download within 10 years.[7]
The distinction where "on-line" is seen as virtuality and "off-line" as reality is sometimes inverted, with Windows Media Download "on-line" concepts being used to define and to explain "off-line" activities, rather than (as per the conventions of Windows Media Download the desktop metaphor with its desktops, trash cans, folders, and so forth) Windows Media Download the other way around. Several cartoons by The New Yorker have satirized this. One includes Saint Peter asking for a user name and Windows Media Download a password before admitting a man into Heaven. Another illustrates "the off-line store" where "All items are actual size!", where Live Masenger Download Free shoppers Windows Media Download may "Take it home as soon as you Windows Media Download pay for it!", and where "Merchandise may Windows Media Download be handled prior to purchase!". |
