A download manager is a computer program dedicated to the task of downloading (and Rent Movies Download sometime uploading) possibly unrelated stand-alone files from (and sometime to) the Internet for storage. This is unlike a World Wide Web browser, which is mainly intended to browse web pages, composed of a Rent Movies Download multitude of smaller files, where error-free moving Rent Movies Download of files for permanent storage is of secondary importance. (A Rent Movies Download failed or incomplete web page file rarely ruins the page.) The Rent Movies Download typical download manager Rent Movies Download at a Rent Movies Download minimum provides means to recover from errors without losing the work already completed, and can optionally split the file to be downloaded (or uploaded) into 2 or more segments, which are then moved Mp3 Download Converters in parallel, potentially making the process faster within the limits of the Rent Movies Download available bandwidth. (A few servers are known to Rent Movies Download block moving Rent Movies Download files in parallel segments, on the principle Rent Movies Download that server capacity should be shared equally by all users.) Multi-source is Rent Movies Download the name given to files that are downloaded in parallel.
There are several things that some web browsers are Rent Movies Download not very good at. That's where the download managers enter the equation:
Pausing the downloading of large files.
Resuming broken or Rent Movies Download paused downloads (especially for very Rent Movies Download large files).
Downloading files on poor connections.
Downloading several files from a site automatically according to simple rules Rent Movies Download (file types, updated Rent Movies Download files, etc. - see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, automatic hang-up and shutdown).
Searching for mirror sites, and the handling of different connections to download the same Rent Movies Download file Rent Movies Download more quickly (segmented downloading).
Download managers are useful for active Internet users. For Rent Movies Download dial-up users, they can automatically dial the internet service provider at night, when rates or tariffs 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 Rent Movies Download for later download. For broadband users, Rent Movies Download download managers can help download very large files by resuming broken Rent Movies Download downloads, by limiting the bandwidth used, so that other Wii Videos For Download internet activities are not affected (slowed) and the server is not overloaded, or by automatically navigating a site and downloading pre-specified content (photo galleries, MP3 collections, etc.) this can also include automatically downloading Wii Tutorial Videos For Download whole sites and regularly Rent Movies Download updating them (see Mirroring).
Many download managers support Metalink, an XML file listing mirrors, checksums, Rent Movies Download and other information useful for downloading.
See below Rent Movies Download for some examples of commonly used download managers. Some downloaders are Rent Movies Download optimized for a 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 the user interface.
Related to download managers are two other breeds of Internet Rent Movies Download programs, file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and Rent Movies Download stream recorders (such as StreamBox VCR).
While download managers are designed to give users greater control over Rent Movies Download downloads, some downloaders are created to give that control Rent Movies Download to content distributors instead. Some software companies, for example Adobe [1], provide such downloaders for downloading software on their own site. Presumably this increases reliability and reduces tech support Rent Movies Download costs Rent Movies Download to them. A possible Rent Movies Download reason is increasing the control over redistribution of their software (even when the software is freeware).In computer technology and telecommunication, Rent Movies Download on-line and off-line are defined by Federal Standard 1037C. Rent Movies Download They are states or conditions of a Download Super Mario Bros Theme Song "device or equipment" Rent Movies Download or of "a functional unit". To be considered on-line, a Rent Movies Download device must be at least one Rent Movies Download of:
"Under the direct control of another device"
"Under the direct control of the system with which it is associated"
"Available for immediate use on Rent Movies Download demand by the Rent Movies Download system without Rent Movies Download 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 power source disconnected Rent Movies Download or turned off", and is "off-power").
One example of a common use Rent Movies Download of these concepts is a Mail User Agent that can be Rent Movies Download instructed to Rent Movies Download be in either "on-line" or "off-line" states. One such MUA Rent Movies Download is Microsoft Outlook. When it is "on-line" it will attempt to Rent Movies Download connect to mail servers (to check for new mail at regular Rent Movies Download intervals, Rent Movies Download for example), and when Rent Movies Download it is "off-line" it will Rent Movies Download not attempt to make any such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect the connection 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 connection, but Rent Movies Download may wish for Outlook to be off-line, so 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 Rent Movies Download application such as Outlook attempts to make connection to a server), but the connection may be an expensive telephone call from the Rent Movies Download particular location in which the computer currently happens to be Rent Movies Download (such as a hotel room) and the user may not wish Outlook Rent Movies Download to trigger making that call every 5 or 10 minutes to check for mail.[1]
Another example of the Rent Movies Download use of these concepts is in the world of digital audio Rent Movies Download technology. A tape Rent Movies Download recorder, digital editor, or other device that is "on-line" is one whose clock is under Rent Movies Download the control of the clock of a "synchronization master" Rent Movies Download device. When the sync master commences playback, the "on-line" device automatically synchronizes Rent Movies Download itself to the master and commences playing from the same Rent Movies Download point in the recording. Whereas a Rent Movies Download device that is "off-line" uses no external clock reference and relies upon its own internal clock. When a large Rent Movies Download number of devices Rent Movies Download are connected to a sync Rent Movies Download master, it is often Rent Movies Download convenient, if one 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 recording system synchronization.)
A third example Rent Movies Download of a common use of these Rent Movies Download concepts is a web Rent Movies Download browser that can be Rent Movies Download instructed Rent Movies Download to be in either "on-line" Rent Movies Download 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 browsed using local copies of those pages that have previously been downloaded whilst in the "on-line" state. This Rent Movies Download can be useful when the computer itself is also off-line, with connection to Internet expensive or Rent Movies Download impossible. The pages are either downloaded Rent Movies Download implicitly into the web browser's own cache, as a result of prior on-line browsing by Rent Movies Download the user, or explicitly by the browser being configured Rent Movies Download to keep local Rent Movies Download copies of certain web pages, which it keeps updated when the browser is in the on-line state, either by checking that the local copies Rent Movies Download are up-to-date at regular Rent Movies Download intervals or by Rent Movies Download checking that the local Rent Movies Download copies are up-to-date whenever the browser Rent Movies Download is switched to Rent Movies Download the on-line state. One such web browser capable of being explicitly configured to download pages for offline Rent Movies Download browsing Rent Movies Download is Rent Movies Download Internet Explorer. When pages are added to the "Favourites" list, they can be marked for being made Rent Movies Download "available for offline browsing". Internet Explorer Rent Movies Download will download to local copies both the marked page and, optionally, all of the pages that it links Rent Movies Download 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 on which local copies are checked to see whether they are up-to-date, are configurable for Wine Download Linux each individual "Favourite" entry.

Offline browsing known as "Offline favourites" was removed Rent Movies Download as a feature in the most recent version of Internet Explorer 7, which only now Rent Movies Download supports single web page saving, but Rent Movies Download not browsing or storing an entire site offline.[citation needed]
Similarly, off-line storage is computer storage that is not "available for immediate Rent Movies Download use on demand by Rent Movies Download the system without human intervention", i.e it is storage that is Rent Movies Download off-line.
The ideas of "on-line" and "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 "off-line" has become a Rent Movies Download subject of study in Rent Movies Download the Rent Movies Download field of sociology.[7]
The distinction between Rent Movies Download "on-line" and "off-line" is conventionally seen as the distinction between computer-mediated communication and face-to-face communication Download Charlie The Unicorn (e.g. Rent Movies Download face Rent Movies Download time), respectively. "On-line" is virtuality, and Rent Movies Download "off-line" is reality Rent Movies Download (e.g. Rent Movies Download real life or meatspace). Slater states that this distinction Google Taskbar Download is "obviously far too simple". To Rent Movies Download support his argument that the distinctions in Rent Movies Download relationships are more complex than a simple "on-line"/"off-line" dichotomy, he observes that some people Rent Movies Download draw no distinction between an Rent Movies Download "on-line" relationship, such as indulging in cybersex, and an "off-line" relationship, such as being pen-pals. He also argues that Rent Movies Download even the telephone can be regarded as an "on-line" experience in some Rent Movies Download circumstances, and that the blurring of the distinctions between the uses of various technologies (such as PDA and mobile telephone, Rent Movies Download television and Internet, and telephone Rent Movies Download and voice-over-IP) has made it "impossible to Rent Movies Download use the term 'on-line' meaningfully in the sense that was employed by the first Rent Movies Download generation of Internet research".[7]
Slater asserts that Rent Movies Download there are legal and regulatory pressures to reduce the distinction between "on-line" and "off-line", with a "general tendency to assimilate online Rent Movies Download to offline and Rent Movies Download erase Clone Cd Free Download the distinction", stressing, however, that this does not Rent Movies Download mean that on-line relationships are Rent Movies Download being reduced to pre-existing off-line relationships. He conjectures that greater legal status may be assigned to on-line relationships (pointing Rent Movies Download out that contractual relationships, Rent Movies Download such as business transactions, on-line are already seen as just as Rent Movies Download "real" as their off-line counterparts), although he states it to be hard to imagine courts awarding palimony to people who have had a Rent Movies Download purely on-line sexual relationship. He also conjectures that Logicmaster Download an "on-line"/"off-line" Rent Movies Download distinction may be seen by people as "rather quaint and not Rent Movies Download 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" Rent Movies Download concepts being used to define and to explain "off-line" activities, rather than (as per Rent Movies Download the conventions of the desktop Rent Movies Download metaphor with Rent Movies Download its desktops, trash cans, folders, 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 Rent Movies Download and a Rent Movies Download password before admitting a man into Heaven. Another Rent Movies Download illustrates "the off-line store" where "All Rent Movies Download items are actual size!", Rent Movies Download where shoppers Rent Movies Download may "Take it home as soon as you pay for it!", Rent Movies Download and where "Merchandise may be handled prior to purchase!". |
