A download manager is a Samsung A920 Pc Connect Download computer Samsung A920 Pc Connect Download 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 unlike a World Wide Web browser, which is mainly intended to browse Samsung A920 Pc Connect Download web pages, composed of a multitude of smaller Samsung A920 Pc Connect Download files, where error-free moving of files for permanent storage is of Samsung A920 Pc Connect Download secondary importance. (A failed or incomplete web page file rarely ruins the page.) The typical download manager at Samsung A920 Pc Connect Download a minimum provides means to recover from errors without Samsung A920 Pc Connect Download Download For Microsoft Office Business losing the work already completed, and can optionally split the file to be downloaded (or uploaded) Microsoft Xml6 Download into 2 or more segments, which are then moved in Samsung A920 Pc Connect Download parallel, potentially making the process faster within Samsung A920 Pc Connect Download the limits of the available bandwidth. (A few servers Samsung A920 Pc Connect Download are known to block moving files in parallel segments, on the Samsung A920 Pc Connect Download principle that server capacity should be shared equally by all users.) Multi-source is the name given to files that are downloaded in parallel.
There are several things that some web browsers are not very good at. Samsung A920 Pc Connect Download That's where the download managers enter the equation:
Pausing Samsung A920 Pc Connect Download the downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor connections.
Downloading Samsung A920 Pc Connect Download several files from a site automatically according to simple rules Samsung A920 Pc Connect Download (file types, updated Samsung A920 Pc Connect Download files, etc. Samsung A920 Pc Connect Download - see also Offline Browser).
Automatic recursive downloads Samsung A920 Pc Connect Download (mirroring).
Scheduled downloads (including, automatic hang-up Samsung A920 Pc Connect Download 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 internet service provider Samsung A920 Pc Connect Download at night, Samsung A920 Pc Connect Download when rates or tariffs are usually lower, download the specified files, and hang-up. They can record which links the user clicks Samsung A920 Pc Connect Download on during the day, and queue these files for later download. For broadband Samsung A920 Pc Connect Download users, download managers can help download very large files by resuming broken downloads, by limiting the bandwidth used, so that other internet activities are not affected (slowed) and the server Samsung A920 Pc Connect Download 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 whole Samsung A920 Pc Connect Download sites Samsung A920 Pc Connect Download and regularly updating them (see Mirroring).
Many download managers support Metalink, an XML file listing mirrors, checksums, and other information useful Samsung A920 Pc Connect Download for downloading.
See below for some examples of commonly used download managers. Some downloaders are optimized Samsung A920 Pc Connect Download for a certain function. Samsung A920 Pc Connect Download For example, Offline Explorer is designed to download entire websites.
Download managers, such as Go!Zilla, were among the first adware Samsung A920 Pc Connect Download applications displaying a banner ad in the user interface.
Related to download managers are two other breeds Samsung A920 Pc Connect Download of Internet Samsung A920 Pc Connect Download programs, file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such as StreamBox VCR).
While download managers are Samsung A920 Pc Connect Download designed to give users greater control over downloads, some downloaders are created to give Samsung A920 Pc Connect Download that control to content distributors instead. Some software companies, Samsung A920 Pc Connect Download for Samsung A920 Pc Connect Download example Adobe [1], Samsung A920 Pc Connect Download provide such downloaders for downloading software Samsung A920 Pc Connect Download on their own site. Presumably this increases reliability and reduces tech support costs to them. A possible reason is increasing the control over Samsung A920 Pc Connect Download redistribution of their software Samsung A920 Pc Connect Download (even when the software is Samsung A920 Pc Connect Download freeware).In computer technology and telecommunication, Samsung A920 Pc Connect Download on-line and Samsung A920 Pc Connect Download off-line are defined by Federal Standard 1037C. Samsung A920 Pc Connect Download They Samsung A920 Pc Connect Download are Samsung A920 Pc Connect Download states or conditions of a "device or Samsung A920 Pc Connect Download equipment" or of "a functional unit". To be considered on-line, a device must be at least one Samsung A920 Pc Connect Download of:
"Under the direct control of another device"
"Under Samsung A920 Pc Connect Download the direct control of the system with which Samsung A920 Pc Connect Download it is associated"
|
"Available Samsung A920 Pc Connect Download for immediate use on demand by the system Samsung A920 Pc Connect Download without human intervention"
"Connected to a system, and is in operation"
"Functional and ready for service"
while a device that Samsung A920 Pc Connect Download is off-line is Samsung A920 Pc Connect Download not (e.g. it has "its main power source disconnected or turned off", and is Samsung A920 Pc Connect Download "off-power").
One example of a Samsung A920 Pc Connect Download common use of these concepts is a Mail User Agent that can be instructed to be in either "on-line" or "off-line" states. Samsung A920 Pc Connect Download One such MUA is Microsoft Outlook. When it is "on-line" it Disney Digital Camera Download Software will attempt to Samsung A920 Pc Connect Download connect to mail servers (to check for new mail at regular intervals, for example), Free Solitaire Download Vista and when it is "off-line" it will not attempt to make any Samsung A920 Pc Connect Download 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 Samsung A920 Pc Connect Download itself on-line, connected to Internet via a cable modem or an ADSL connection, but may wish for Outlook to Samsung A920 Pc Connect Download be off-line, so that Samsung A920 Pc Connect Download 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 Download Blackberry Software application such as Outlook attempts to make connection Samsung A920 Pc Connect Download to a server), but the connection may Samsung A920 Pc Connect Download be an expensive telephone call from the particular location in which the computer currently happens to be (such as a hotel Samsung A920 Pc Connect Download room) and the Samsung A920 Pc Connect Download user may not wish Donkey Kong For Mame Download Outlook to trigger making that call Samsung A920 Pc Connect Download every Samsung A920 Pc Connect Download 5 or 10 minutes to check for mail.[1]
Another example of the use of these concepts is in the world of digital audio technology. A Samsung A920 Pc Connect Download 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. 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. Samsung A920 Pc Connect Download When Samsung A920 Pc Connect Download a large number of devices are connected to a sync master, it Samsung A920 Pc Connect Download is often convenient, if one wants to hear just the output of Samsung A920 Pc Connect Download one single device, to take it off-line, because if Samsung A920 Pc Connect Download the device is played back on-line all synchronized devices have to locate the playback point Samsung A920 Pc Connect Download and Samsung A920 Pc Connect Download wait for each other to be in synchronization.[2] Samsung A920 Pc Connect Download (For Samsung A920 Pc Connect Download further related discussion, see MIDI timecode, word sync, Samsung A920 Pc Connect Download and recording system synchronization.)
A third example of a common use of these concepts is a web browser that can be Samsung A920 Pc Connect Download instructed Samsung A920 Pc Connect Download to be Samsung A920 Pc Connect Download 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 can perform Samsung A920 Pc Connect Download offline browsing, Samsung A920 Pc Connect Download where pages Samsung A920 Pc Connect Download can be browsed Samsung A920 Pc Connect Download using local copies of those pages that have previously been Samsung A920 Pc Connect Download downloaded whilst in the "on-line" state. This can be useful when the computer Samsung A920 Pc Connect Download itself is also off-line, with connection to Internet expensive or impossible. The pages Samsung A920 Pc Connect Download are either downloaded implicitly Samsung A920 Pc Connect Download into Samsung A920 Pc Connect Download the web browser's own cache, as Samsung A920 Pc Connect Download a result of prior on-line browsing by the user, or Download Nintendo Emulator explicitly by the Samsung A920 Pc Connect Download browser being configured to keep local Samsung A920 Pc Connect Download copies of certain web pages, which it keeps updated when the browser is in the on-line state, either by checking that Samsung A920 Pc Connect Download the local copies are up-to-date at regular intervals or by checking Samsung A920 Pc Connect Download that the local copies are up-to-date whenever the browser is Samsung A920 Pc Connect Download switched to the on-line state. Samsung A920 Pc Connect Download One 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 "available for offline browsing". Internet Explorer will download to local Samsung A920 Pc Connect 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 Samsung A920 Pc Connect Download amount of local disc space allowed to be consumed, and the schedule on which local copies Download Jibjab are checked to see whether they are up-to-date, are configurable for Samsung A920 Pc Connect Download each Samsung A920 Pc Connect Download individual "Favourite" entry.

Offline browsing known as "Offline favourites" was removed as a feature in the most Samsung A920 Pc Connect Download recent version of Internet Explorer 7, which only now supports single web page saving, but not browsing or storing an entire site offline.[citation needed]
Similarly, off-line Samsung A920 Pc Connect Download storage is computer storage Samsung A920 Pc Connect Download that is not "available Samsung A920 Pc Connect Download for immediate use on demand by the system without human intervention", i.e Samsung A920 Pc Connect Download it is storage Samsung A920 Pc Connect Download that is 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 subject of study in the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as the distinction between computer-mediated Samsung A920 Pc Connect Download communication and face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, and "off-line" is Samsung A920 Pc Connect Download reality (e.g. Samsung A920 Pc Connect Download real Samsung A920 Pc Connect Download life or meatspace). Slater states that this Samsung A920 Pc Connect Download distinction is "obviously far too simple". To support his Samsung A920 Pc Connect Download argument that the distinctions in relationships are more complex than Samsung A920 Pc Connect Download a Samsung A920 Pc Connect Download simple "on-line"/"off-line" dichotomy, Samsung A920 Pc Connect Download he observes that some people draw no distinction between an "on-line" Samsung A920 Pc Connect Download relationship, such Samsung A920 Pc Connect Download as indulging Samsung A920 Pc Connect Download in cybersex, and an "off-line" Samsung A920 Pc Connect Download relationship, such as Samsung A920 Pc Connect Download being pen-pals. He also argues that even the telephone can be regarded Samsung A920 Pc Connect Download as Samsung A920 Pc Connect Download 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, television and Internet, and telephone and voice-over-IP) has Samsung A920 Pc Connect Download made it "impossible to use the term 'on-line' meaningfully in the sense that was employed by the first Samsung A920 Pc Connect Download generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures to reduce the distinction between Gay Torrent Download "on-line" and "off-line", with a "general tendency to Samsung A920 Pc Connect Download assimilate online to offline and erase the distinction", stressing, however, that this does not mean that on-line Samsung A920 Pc Connect Download relationships are being reduced to pre-existing off-line relationships. He conjectures that Samsung A920 Pc Connect Download greater legal status may be Samsung A920 Pc Connect Download assigned to on-line relationships (pointing out that contractual relationships, such as business transactions, on-line are already seen as just as Samsung A920 Pc Connect Download "real" Download Hd Media Player as their off-line counterparts), although he states it to be hard to imagine courts awarding palimony to people who have had Samsung A920 Pc Connect Download 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 Samsung A920 Pc Connect Download where "on-line" is seen as virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used to define and to explain "off-line" activities, rather than (as per the conventions Samsung A920 Pc Connect Download of the desktop metaphor with its desktops, trash cans, folders, and so forth) the Samsung A920 Pc Connect Download other way around. Several cartoons by The New Yorker have satirized this. One includes Saint Peter asking for a user name and a Samsung A920 Pc Connect Download password before admitting a Samsung A920 Pc Connect Download man into Heaven. Another illustrates "the off-line store" where "All Motec I2 Download items are actual size!", where shoppers may "Take it home as soon as Samsung A920 Pc Connect Download you pay for it!", and where Samsung A920 Pc Connect Download "Merchandise may be handled prior Samsung A920 Pc Connect Download to purchase!". |
