A download manager is a computer program dedicated Download Hd Media Player to the task of downloading (and sometime uploading) possibly unrelated stand-alone files from (and sometime to) the Internet Download Hd Media Player for storage. This is Download Hd Media Player unlike a World Wide Web browser, which is mainly intended to Download Hd Media Player browse web Download Hd Media Player pages, composed of a multitude of smaller files, where error-free moving of files for permanent storage is of secondary importance. Download Hd Media Player (A failed or incomplete web page file rarely ruins the page.) The typical download manager at a Download Hd Media Player minimum provides means to recover from errors without losing the Download Hd Media Player work already completed, and can optionally split the file to be downloaded (or uploaded) into 2 or Download Hd Media Player 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 to block moving files in parallel segments, on the principle that server capacity should be shared equally by all users.) Multi-source is Download Hd Media Player the name given to Download Hd Media Player files that are downloaded in parallel.
There Download Hd Media Player are several things that some Download Hd Media Player web browsers are not very good at. That's where the Download Hd Media Player download managers Download Hd Media Player enter the equation:
Pausing the downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files Download Hd Media Player on Download Hd Media Player poor connections.
Downloading several files from a site automatically according to simple rules (file Download Hd Media Player types, updated files, etc. Download Hd Media Player - 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 file more quickly (segmented downloading).
Download Download Hd Media Player managers are useful for Free Download Cellphone Games active Internet users. For dial-up users, they can automatically dial the Download Hd Media Player internet service Download Hd Media Player provider at night, when rates or tariffs are usually lower, download the specified files, and hang-up. Download For Microsoft Office Business They can record which Microsoft Xml6 Download links the user clicks on during Disney Digital Camera Download Software the day, and queue these files for later download. For broadband 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 Download Hd Media Player 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 Download Hd Media Player automatically downloading whole sites and regularly updating them (see Mirroring).
Many Download Hd Media Player download managers support Metalink, an XML file listing mirrors, checksums, Download Hd Media Player and other Download Hd Media Player information useful for downloading.
See below for Download Hd Media Player some examples Download Hd Media Player of Download Hd Media Player commonly used download managers. Some downloaders are optimized for a certain function. Download Hd Media Player For Download Hd Media Player example, Offline Explorer is designed to download entire websites.
Download managers, such as Go!Zilla, were among the first adware applications displaying Download Hd Media Player a banner ad in the user interface.
Related to download managers are two other breeds of Internet programs, Download Hd Media Player file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such Download Hd Media Player as StreamBox VCR).
While Download Hd Media Player download managers are designed Download Hd Media Player 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 Download Hd Media Player on their own site. Presumably this increases Download Hd Media Player reliability and reduces tech support costs to them. A possible reason is increasing the control over redistribution of their software (even when the software is freeware).In computer technology and telecommunication, on-line Download Hd Media Player and Download Hd Media Player off-line are defined Download Hd Media Player by Federal Standard 1037C. They are states or Download Hd Media Player Free Solitaire Download Vista conditions of a "device or equipment" or Download Hd Media Player of "a functional unit". To Download Hd Media Player be considered on-line, a Download Hd Media Player device must be at least one of:
"Under the direct control Download Hd Media Player of another device"
"Under the Download Hd Media Player direct control Download Hd Media Player of the Download Hd Media Player system with which it is associated"
"Available for immediate Download Hd Media Player use on demand by the system without human Download Hd Media Player intervention"
"Connected to a system, and is in operation"
"Functional and ready for service"
while a device Download Hd Media 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 Download Hd Media Player use of these concepts is a Mail User Agent that can be instructed to be in either Download Hd Media Player "on-line" or "off-line" states. One such MUA is Microsoft Outlook. When it is "on-line" it will attempt to connect to mail servers (to check for new mail at regular intervals, for example), and when it Download Hd Media Player is "off-line" it will not attempt to make any such connections. The "on-line" Download Hd Media Player or "off-line" state of Download Hd Media Player the MUA does not necessarily reflect the connection status Download Hd Media Player between the Download Hd Media Player computer on which Download Hd Media Player it is running and Download Hd Media Player Internet. The user may have the Download Blackberry Software computer itself on-line, connected to Internet via a cable modem or an ADSL connection, but may wish for Outlook Download Hd Media Player to Download Hd Media Player be off-line, so that it makes no attempt to Download Hd Media Player send or to receive messages. Or the computer may be configured to Download Hd Media Player employ Download Hd Media Player a dial-up connection on demand (whenever an application such as Outlook attempts to make connection to Download Hd Media Player a Download Hd Media Player server), but the connection may be Download Hd Media Player an expensive telephone call Download Hd Media Player 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 Download Hd Media Player that call every Download Hd Media Player 5 or 10 minutes to check for mail.[1]
Another example of the use of these concepts is in the world Download Hd Media Player of digital Download Hd Media Player audio technology. A tape recorder, digital editor, or other device that is "on-line" Download Hd Media Player is one whose clock is under the control of the Download Hd Media Player clock of a "synchronization master" device. When the sync master commences playback, the "on-line" device automatically synchronizes itself Download Hd Media Player to the master Download Hd Media Player 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 Download Hd Media Player large number of devices are connected Donkey Kong For Mame Download to a Download Hd Media Player sync master, it is often convenient, if one wants Download Hd Media Player to hear Download Hd Media Player just the output of one single device, to take it Download Hd Media Player off-line, because if the device Download Hd Media Player is played back on-line all synchronized devices have to locate Download Hd Media Player the playback point and wait Download Hd Media Player for each other to be in synchronization.[2] (For Download Hd Media Player further related discussion, Download Hd Media Player see MIDI timecode, Download Hd Media Player 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 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 Download Hd Media Player 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 the computer itself is Download Hd Media Player also off-line, with connection to Internet Download Hd Media Player expensive or impossible. The pages are either downloaded implicitly into the web browser's own cache, as a result of prior Download Hd Media Player on-line browsing by the user, or explicitly by the browser being configured to keep local copies of Download Hd Media Player certain web pages, which it keeps updated when the Download Hd Media Player browser Download Hd Media Player is Download Hd Media Player in the on-line state, Download Hd Media Player either by checking that the local copies are up-to-date at Download Nintendo Emulator regular intervals or by checking that the local copies are up-to-date whenever the browser is switched to the on-line state. One such web browser Download Hd Media Player capable of being explicitly configured to download pages for offline browsing is Internet Explorer. When pages are added Download Hd Media Player to the "Favourites" list, they can be marked for being made Download Hd Media Player "available for offline browsing". Internet Explorer will download to local copies both the marked page and, optionally, all of the pages that it links to. In Internet Explorer version 6, the level Download Hd Media Player of direct and indirect links, the maximum Download Hd Media Player amount of local disc space allowed to be Download Hd Media Player consumed, and Download Hd Media Player the schedule on which local copies are checked to see whether they are up-to-date, are configurable for each individual "Favourite" entry.

Offline browsing known as Download Hd Media Player "Offline favourites" was removed as a feature in the Download Hd Media Player most 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 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 Hd Media Player of "on-line" Download Hd Media Player and "off-line" have been generalized from Download Hd Media Player computing and telecommunication into the Download Hd Media Player field of human interpersonal Download Hd Media Player relationships. The distinction between what is considered "on-line" and what is Download Hd Media Player considered "off-line" has Download Hd Media Player become a subject of study in the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally Download Hd Media Player 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 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, Download Hd Media Player he Download Hd Media Player observes Download Jibjab that some people draw no distinction between an "on-line" relationship, such as indulging Download Hd Media Player 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" experience in some circumstances, Download Hd Media Player and that the blurring of the distinctions between the uses of various technologies (such as Download Hd Media Player PDA and mobile telephone, television and Internet, and telephone and voice-over-IP) has made it "impossible to use Download Hd Media Player the Download Hd Media Player term 'on-line' meaningfully in the sense Download Hd Media Player that was employed by the first generation of Internet research".[7]
Slater asserts that there are Gay Torrent Download 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 not mean that on-line relationships are being reduced to pre-existing off-line relationships. He conjectures that greater legal status may Download Hd Media Player be assigned to on-line relationships Download Hd Media Player (pointing out that contractual Download Hd Media Player relationships, such as business transactions, on-line are already seen as just as "real" as their off-line counterparts), although he states it to be hard to Download Hd Media Player imagine courts awarding palimony to people who have had a purely on-line sexual Download Hd Media Player relationship. He also conjectures that an "on-line"/"off-line" distinction may Download Hd Media Player be seen by people as "rather quaint and not quite comprehensible" within 10 years.[7]
The distinction where "on-line" Download Hd Media Player is seen as virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used Download Hd Media Player to define and Download Hd Media Player to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash cans, folders, and so forth) the Download Hd Media Player other way around. Several cartoons by Download Hd Media Player The New Yorker have satirized this. One includes Saint Peter asking for a user name Download Hd Media Player and a password before admitting a man Download Hd Media Player into Download Hd Media Player Heaven. Download Hd Media Player Another illustrates "the off-line store" where "All items are actual size!", where shoppers may "Take it home as soon as you pay Download Hd Media Player for it!", and where "Merchandise may be handled prior to purchase!". |
