A download manager is a Snoqualmie Screensaver Free Download computer program Snoqualmie Screensaver Free Download dedicated to the task of downloading Snoqualmie Screensaver Free Download (and sometime uploading) possibly unrelated stand-alone Snoqualmie Screensaver Free Download files from (and sometime to) the Internet Snoqualmie Screensaver Free Download for storage. This Snoqualmie Screensaver Free Download is unlike a World Wide Web browser, which is Snoqualmie Screensaver Free Download mainly Snoqualmie Screensaver Free Download intended to browse web Snoqualmie Screensaver Free Download pages, composed of a multitude of smaller files, where error-free moving of files for permanent storage is of secondary importance. (A failed or incomplete Snoqualmie Screensaver Free Download web page file rarely ruins the page.) The typical download manager at a minimum provides means to recover from Snoqualmie Screensaver Free Download errors without losing the work already completed, and can optionally split the file to Snoqualmie Screensaver Free Download be Snoqualmie Screensaver Free Download downloaded (or Snoqualmie Screensaver Free Download uploaded) into 2 or more segments, which are then Snoqualmie Screensaver Free Download moved in parallel, potentially making the process faster Snoqualmie Screensaver Free Download within Snoqualmie Screensaver Free Download the limits of the available bandwidth. (A few servers are known to block moving files in parallel segments, on Snoqualmie Screensaver Free Download the principle that server capacity should be shared equally by all users.) Snoqualmie Screensaver Free Download Multi-source is the name given to files that are downloaded in Snoqualmie Screensaver Free Download parallel.
There are Snoqualmie Screensaver Free Download several Snoqualmie Screensaver Free Download things that some web browsers are not very good at. That's where the download managers enter the equation:
Pausing the downloading Snoqualmie Screensaver Free Download 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 Snoqualmie Screensaver Free Download simple rules (file types, updated files, etc. - see also Offline Snoqualmie Screensaver Free Download 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 file more quickly (segmented downloading).
Download managers are useful for active Internet users. For dial-up users, they can automatically dial the Snoqualmie Screensaver Free Download internet service provider at night, when rates or tariffs are usually lower, download the specified files, Snoqualmie Screensaver Free Download and hang-up. Snoqualmie Screensaver Free Download They can record which links the user clicks on during the day, and queue these files for later download. For broadband users, Snoqualmie Screensaver Free Download download managers can help download very large files by resuming Snoqualmie Screensaver Free Download broken downloads, by limiting the bandwidth Snoqualmie Screensaver Free Download used, so that other internet activities are not affected (slowed) and the server is not overloaded, or by automatically navigating a site and Snoqualmie Screensaver Free Download downloading pre-specified content (photo galleries, MP3 Snoqualmie Screensaver Free Download collections, etc.) this can also include automatically downloading whole Snoqualmie Screensaver Free Download sites and regularly updating them (see Snoqualmie Screensaver Free Download Mirroring).
Many download managers support Metalink, an XML file listing mirrors, checksums, Snoqualmie Screensaver Free Download and other information Snoqualmie Screensaver Free Download useful for downloading.
See below for some examples of commonly used download managers. Some Snoqualmie Screensaver Free Download downloaders are optimized for a certain function. For example, Offline Explorer is designed Snoqualmie Screensaver Free Download to download entire websites.
Download managers, such as Go!Zilla, were Snoqualmie Screensaver Free Download among the first adware applications displaying a banner ad in the user Download Video Silvia Saint interface.

Related to download managers are two Snoqualmie Screensaver Free Download other 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 Snoqualmie Screensaver Free Download designed to give users greater control over downloads, some downloaders are created to give that control to content distributors instead. Some software companies, for Snoqualmie Screensaver Free Download example Adobe [1], provide such downloaders for downloading software on their own site. Presumably this increases Snoqualmie Screensaver Free Download reliability and reduces tech support costs to them. A possible Snoqualmie Screensaver Free Download reason is increasing the control over How To Download To Mp3 Player redistribution Snoqualmie Screensaver Free Download of their software (even when the software is freeware).In computer technology and telecommunication, on-line and Snoqualmie Screensaver Free Download off-line are defined Snoqualmie Screensaver Free Download by Federal Standard 1037C. They are states or conditions of a "device or equipment" or of "a functional unit". To be Snoqualmie Screensaver Free Download considered on-line, a device Snoqualmie Screensaver Free Download must be at least one of:
"Under the direct control Snoqualmie Screensaver Free Download of Snoqualmie Screensaver Free Download another device"
"Under the direct control of the system with Snoqualmie Screensaver Free Download which it is associated"
"Available for Snoqualmie Screensaver Free Download immediate use on demand by the system without human intervention"
"Connected to a system, and is Snoqualmie Screensaver Free Download in operation"
"Functional and ready for service"
while a Snoqualmie Screensaver Free Download device that is off-line is not (e.g. it Snoqualmie Screensaver Free Download has "its main power source disconnected Snoqualmie Screensaver Free Download or turned off", and is "off-power").
One example of a common use of these concepts is a Mail User Agent that can Snoqualmie Screensaver Free Download be instructed to be in either "on-line" Snoqualmie Screensaver Free Download or "off-line" states. Snoqualmie Screensaver Free Download One such MUA is Microsoft Outlook. When Download Free Xxx Pictures Cell Phones it is "on-line" it will attempt to connect to mail servers (to check for new Snoqualmie Screensaver Free Download mail at regular intervals, for Snoqualmie Screensaver Free Download example), and when it is "off-line" it will not attempt to make any such Snoqualmie Screensaver Free Download connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect Snoqualmie Screensaver Free Download the connection status between the computer Snoqualmie Screensaver Free Download on which it is Snoqualmie Screensaver Free Download running and Internet. The user may have the computer Snoqualmie Screensaver Free Download itself on-line, connected to Internet via a cable modem or an ADSL connection, but may wish for Snoqualmie Screensaver Free Download 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 application such as Outlook Snoqualmie Screensaver Free Download attempts to make connection to a server), but the connection may be an expensive telephone call from the particular Snoqualmie Screensaver Free Download location in which the Snoqualmie Screensaver Free Download computer currently happens to be (such as a hotel room) and the user may not wish Outlook Snoqualmie Screensaver Free Download to trigger making that call every 5 or 10 minutes to Snoqualmie Screensaver Free Download check for mail.[1]
Another Snoqualmie Screensaver Free Download example of the use of these Snoqualmie Screensaver Free Download concepts is in the world of digital audio Snoqualmie Screensaver Free Download technology. A tape Snoqualmie Screensaver Free Download recorder, Snoqualmie Screensaver Free Download digital editor, or other device that is "on-line" is one whose clock is under the control of the Snoqualmie Screensaver Free Download 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 external clock reference and relies upon its own internal clock. When a large number of devices are connected to a sync master, it is often convenient, Snoqualmie Screensaver Free Download if one wants to hear just the output of one single device, to take it off-line, because if the device is Snoqualmie Screensaver Free Download played back on-line all synchronized devices have to Snoqualmie Screensaver Free Download locate the playback point and wait for each other to be in synchronization.[2] (For further related discussion, see MIDI timecode, word sync, Snoqualmie Screensaver Free Download 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 either "on-line" or "off-line" states. The browser only attempts to fetch pages from servers whilst Snoqualmie Screensaver Free Download in the "on-line" state. In Snoqualmie Screensaver Free Download the "off-line" state, users can perform offline browsing, where pages can be browsed using local copies of those pages that have previously Snoqualmie Screensaver Free Download been downloaded whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with connection to Snoqualmie Screensaver Free Download Internet expensive or impossible. The pages are either Snoqualmie Screensaver Free Download downloaded implicitly into the web browser's own cache, as a result of prior Snoqualmie Screensaver Free Download on-line browsing by the user, or explicitly Snoqualmie Screensaver Free Download by the browser being configured to keep local copies of certain web pages, which Snoqualmie Screensaver Free Download it keeps updated when the browser is in the on-line state, either by checking that the local Snoqualmie Screensaver Free Download copies are up-to-date at regular intervals or by checking that the local copies are up-to-date Snoqualmie Screensaver Free Download whenever the browser is switched Snoqualmie Screensaver Free Download to Snoqualmie Screensaver Free Download the on-line state. One such web browser capable of being explicitly configured to download pages for offline browsing Snoqualmie Screensaver Free Download is Internet Explorer. When pages Snoqualmie Screensaver Free Download are added to the "Favourites" list, they can be marked for being made "available Snoqualmie Screensaver Free Download for offline browsing". Internet Explorer will download to local Snoqualmie Screensaver Free Download copies both the marked page and, optionally, all of the pages that it links to. In Internet Explorer version 6, the level of direct and indirect links, the maximum amount of local Snoqualmie Screensaver Free Download disc space allowed to be consumed, and the schedule on which Snoqualmie Screensaver Free Download local copies are checked to see whether they are up-to-date, are configurable for Snoqualmie Screensaver Free Download each Snoqualmie Screensaver Free Download individual "Favourite" entry.

Offline browsing known as "Offline favourites" was removed as a feature in the most recent version of Snoqualmie Screensaver Free Download Internet Explorer 7, which only now supports single web Snoqualmie Screensaver Free Download page saving, but not 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 without human intervention", i.e it is storage that is off-line.
The ideas Snoqualmie Screensaver Free Download 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 Snoqualmie Screensaver Free Download "off-line" has become a subject of study in the field Snoqualmie Screensaver Free Download of sociology.[7]
The Snoqualmie Screensaver Free Download distinction between "on-line" and Snoqualmie Screensaver Free Download "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" Snoqualmie Screensaver Free Download is reality (e.g. real life or meatspace). Slater states that this distinction Snoqualmie Screensaver Free Download is "obviously far too simple". To support his argument that Snoqualmie Screensaver Free Download the Snoqualmie Screensaver Free Download distinctions in Survey Finite Download relationships are more complex than Snoqualmie Screensaver Free Download Free Align It Game Download 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 Snoqualmie Screensaver Free Download that Snoqualmie Screensaver Free Download even the Snoqualmie Screensaver Free Download telephone can be regarded Snoqualmie Screensaver Free Download as an "on-line" experience in some Snoqualmie Screensaver Free Download circumstances, and that the blurring of the distinctions between Snoqualmie Screensaver Free Download the uses of various technologies (such as PDA Snoqualmie Screensaver Free Download and mobile telephone, television and Internet, and telephone Snoqualmie Screensaver Free Download and voice-over-IP) has made it "impossible to use the Snoqualmie Screensaver Free Download term 'on-line' meaningfully in the sense that was employed by the first generation Snoqualmie Screensaver Free Download of Internet research".[7]

Slater asserts that there are legal and regulatory pressures to reduce the distinction between "on-line" and Snoqualmie Screensaver Free Download "off-line", with a "general tendency Snoqualmie Screensaver Free Download to assimilate online to offline Snoqualmie Screensaver Free Download and erase the distinction", stressing, however, that this 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 are already seen as just Snoqualmie Screensaver Free Download as "real" as their 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. He also conjectures that an "on-line"/"off-line" distinction may be seen by people Snoqualmie Screensaver Free Download as "rather Snoqualmie Screensaver Free Download quaint and not quite comprehensible" within 10 years.[7]
The distinction where "on-line" is seen as virtuality and "off-line" as Snoqualmie Screensaver Free Download reality is sometimes inverted, with "on-line" concepts being used to define and to explain "off-line" Snoqualmie Screensaver Free Download activities, rather than (as per the conventions of the Snoqualmie Screensaver Free Download desktop metaphor with its desktops, trash cans, folders, and so forth) the Adriana Sage Download other way around. Several cartoons by The New Yorker have Snoqualmie Screensaver Free Download satirized this. One includes Saint Peter asking for a user name Snoqualmie Screensaver Free Download and a password before admitting a Snoqualmie Screensaver Free Download 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 pay for it!", and where "Merchandise may be handled Snoqualmie Screensaver Free Download prior Snoqualmie Screensaver Free Download to purchase!". |
