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 unlike a Lge U8xxx Driver Download World Wide Web browser, which is mainly intended to browse web Lge U8xxx Driver 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 web page file rarely ruins the page.) The typical download manager at a minimum provides Cricket Download Free Phone Ringtone means to recover from errors without losing Lge U8xxx Driver Download the work already completed, Lge U8xxx Driver Download and can optionally split the file to be Lge U8xxx Driver Download downloaded (or uploaded) into 2 or more segments, which are then moved Lge U8xxx Driver Download in parallel, potentially making the process faster within the limits of the available bandwidth. (A few servers are known to block moving Lge U8xxx Driver Download files in parallel segments, on the principle that server capacity should be shared equally by all Lge U8xxx Driver Download 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. That's where the download managers enter the equation:
Pausing the downloading of large files.
Resuming broken or paused downloads (especially Lge U8xxx Driver Download for very large files).
Downloading files on Lge U8xxx Driver Download poor connections.
Downloading Lge U8xxx Driver Download several files from a site automatically Lge U8xxx Driver Download according to simple rules (file types, updated files, etc. - see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, automatic hang-up and shutdown).
Searching for Lge U8xxx Driver Download mirror Lge U8xxx Driver Download sites, and the handling of different connections to download Lge U8xxx Driver Download the same Lge U8xxx Driver Download file more quickly (segmented downloading).
Download Lge U8xxx Driver Download managers are useful for active Internet users. For 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 Lge U8xxx Driver Download hang-up. They can record which links the user clicks on Lge U8xxx Driver Download during the day, and queue these files for Lge U8xxx Driver Download later download. For broadband users, download managers can help download Hp Officejet Download Software very large files by resuming broken downloads, Lge U8xxx Driver Download by limiting the bandwidth used, so that other internet activities are not affected (slowed) and the server is Lge U8xxx Driver Download not overloaded, or by automatically Lge U8xxx Driver Download navigating a site and downloading pre-specified content (photo galleries, MP3 collections, etc.) this can also include Lge U8xxx Driver Download automatically downloading whole sites and regularly updating them (see Mirroring).
Many download managers support Metalink, an XML file listing mirrors, checksums, and other information Lge U8xxx Driver Download useful for downloading.
See below for some examples of commonly used download Lge U8xxx Driver Download managers. Some downloaders are optimized for a certain function. For example, Offline Explorer Lge U8xxx Driver Download is designed Lge U8xxx Driver Download to download entire websites.
Download managers, such Lge U8xxx Driver Download as Go!Zilla, were Lge U8xxx Driver Download among the first adware applications displaying a banner ad in the user interface.
Related Lge U8xxx Driver Download to Lge U8xxx Driver Download download managers are two 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 designed to give users greater control over downloads, some downloaders are created to give that Lge U8xxx Driver Download control to content distributors instead. Some software companies, Lge U8xxx Driver Download for example Adobe [1], provide such downloaders for downloading software on their own site. Presumably this increases 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 and Lge U8xxx Driver Download off-line are defined by Federal Standard 1037C. They are states or conditions of a "device or equipment" or of "a functional unit". To be considered on-line, a device must be at least one of:
"Under the direct Lge U8xxx Driver Download control of another device"
"Under the direct control of the system with which it is associated"
"Available for immediate use on demand by the system without human intervention"
"Connected to a Lge U8xxx Driver Download system, and is in operation"
"Functional and ready for service"
while a Lge U8xxx Driver Download device that is off-line is not (e.g. it Lge U8xxx Driver Download has "its Lge U8xxx Driver Download main power source disconnected or turned off", and is Lge U8xxx Driver Download "off-power").
One example of a common use of these Lge U8xxx Driver Download 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 to connect to Lge U8xxx Driver Download mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" it will not attempt Lge U8xxx Driver Download to make any such connections. The "on-line" or "off-line" state of the MUA does not necessarily Lge U8xxx Driver Download reflect the connection status between the computer on which it is running and Lge U8xxx Driver Download Internet. Lge U8xxx Driver Download The user may Lge U8xxx Driver Download have the computer itself on-line, connected to Lge U8xxx Driver Download Internet via a cable modem or an ADSL connection, but may wish for Outlook to be off-line, Lge U8xxx Driver Download so that it Lge U8xxx Driver Download 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 attempts to make connection Lge U8xxx Driver Download to a server), but Lge U8xxx Driver Download the connection may be an expensive telephone call from the particular location in which the computer currently Lge U8xxx Driver Download happens to be (such as Lge U8xxx Driver Download a Lge U8xxx Driver Download hotel room) and the user may Lge U8xxx Driver Download not wish Outlook to trigger making that call every 5 or 10 minutes to check for mail.[1]
Another example Lge U8xxx Driver Download of the use of Lge U8xxx Driver Download these concepts is Lge U8xxx Driver Download in the world of digital audio technology. A tape recorder, digital editor, or other device that is "on-line" is one whose clock is under the control of Lge U8xxx Driver Download the clock of a "synchronization Lge U8xxx Driver Download master" Lge U8xxx Driver Download 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 Lge U8xxx Driver Download external clock Lge U8xxx Driver Download reference and relies upon its own internal clock. When a large number of devices are connected to a sync master, it is Lge U8xxx Driver Download often convenient, if one wants to hear just the output of one single device, to take it Lge U8xxx Driver Download off-line, because if the device is played back on-line all synchronized devices have to locate the playback point Lge U8xxx Driver Download and wait for each other to be in synchronization.[2] (For Lge U8xxx Driver Download further related discussion, see MIDI timecode, word sync, and recording system Lge U8xxx Driver Download synchronization.)

A third example of a common use of these concepts is a web browser that can be Lge U8xxx Driver Download instructed to Lge U8xxx Driver Download be in either "on-line" or "off-line" Lge U8xxx Driver Download states. The browser only attempts to fetch pages from servers whilst in Download Cfos the "on-line" state. Lge U8xxx Driver Download In the Lge U8xxx Driver Download "off-line" state, users can perform offline browsing, where pages can be Lge U8xxx Driver Download browsed using local Lge U8xxx Driver Download copies of Lge U8xxx Driver Download those pages that have previously been Download Free Kazaa Lite Music downloaded whilst in the "on-line" state. This can be Lge U8xxx Driver Download useful when the computer Lge U8xxx Driver Download itself Lge U8xxx Driver Download is also off-line, with connection to Internet expensive or impossible. Lge U8xxx Driver Download The pages are either downloaded Lge U8xxx Driver Download implicitly into the web browser's Lge U8xxx Driver Download own cache, as Lge U8xxx Driver Download a result Lge U8xxx Driver Download of prior on-line browsing by the user, or explicitly by the browser being configured to keep local copies of certain web pages, which it Lge U8xxx Driver Download keeps updated when the browser is in the on-line state, Lge U8xxx Driver Download either by checking that the local copies are up-to-date at regular intervals or by checking that the local copies are up-to-date whenever the browser is switched to Lge U8xxx Driver Download the on-line state. One Lge U8xxx Driver Download such web browser capable of being explicitly configured to download pages for offline browsing is Internet Explorer. When Lge U8xxx Driver Download pages are added to the "Favourites" list, they can be Lge U8xxx Driver Download marked for being Lge U8xxx Driver Download made "available for offline browsing". Internet Explorer Soulmate Natasha Bedingfield Mp3 Download will download Lge U8xxx Driver Download to local copies both the marked page and, optionally, all of the pages that it Lge U8xxx Driver Download links to. In Internet Explorer version 6, the level of direct and indirect Lge U8xxx Driver Download links, the maximum Lge U8xxx Driver Download amount of local disc space allowed Lge U8xxx Driver Download to Lge U8xxx Driver Download be consumed, and the schedule on Lge U8xxx Driver Download which local copies are Lge U8xxx Driver Download checked to Lge U8xxx Driver Download see whether they are up-to-date, are configurable for each individual "Favourite" entry.

Offline browsing known as "Offline favourites" was removed Lge U8xxx Driver Download as a feature in the most recent version of Lge U8xxx Driver Download Internet Explorer 7, which only now supports single web page saving, Lge U8xxx Driver Download but not browsing or storing an entire site offline.[citation needed]
Similarly, off-line storage is computer storage that is not "available Lge U8xxx Driver Download for immediate use on demand by the system without human intervention", i.e it Lge U8xxx Driver Download is storage 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 Lge U8xxx Driver Download considered "off-line" has become a subject of study in Lge U8xxx Driver Download the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as the distinction Lge U8xxx Driver Download between computer-mediated communication and face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, and "off-line" is reality Lge U8xxx Driver Download (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, he Lge U8xxx Driver Download observes that some people Lge U8xxx Driver Download draw no distinction between an "on-line" relationship, Lge U8xxx Driver Download 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 Lge U8xxx Driver Download "on-line" experience in some circumstances, and that Lge U8xxx Driver Download the blurring of the distinctions Lge U8xxx Driver Download between the uses of various technologies (such as PDA and mobile Lge U8xxx Driver Download telephone, television and Internet, and telephone and voice-over-IP) has made it "impossible to use the term 'on-line' meaningfully in the sense Lge U8xxx Driver Download that was employed by the first generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures to reduce the distinction between "on-line" and "off-line", with a "general Lge U8xxx Driver Download tendency to assimilate Lge U8xxx Driver Download 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 Lge U8xxx Driver Download may be assigned to on-line relationships Lge U8xxx Driver Download (pointing out that contractual relationships, such as business transactions, on-line are already seen as just as "real" as their Lge U8xxx Driver Download off-line counterparts), although he states Lge U8xxx Driver Download it to be hard to imagine courts awarding palimony to people who have had a purely on-line Lge U8xxx Driver Download sexual relationship. He also conjectures that an "on-line"/"off-line" Lge U8xxx Driver Download distinction may be seen Lge U8xxx Driver Download by people as "rather quaint and not quite comprehensible" within 10 years.[7]
The distinction where "on-line" is seen as virtuality and "off-line" Lge U8xxx Driver Download as reality is sometimes inverted, with Lge U8xxx Driver Download "on-line" concepts being used to define and 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 other way around. Several cartoons by The New Yorker have satirized this. One includes Saint Peter asking for a user Lge U8xxx Driver Download name and Lge U8xxx Driver Download a password before admitting a Lge U8xxx Driver Download man into Heaven. Another Lge U8xxx Driver Download illustrates "the off-line store" where "All items are Lge U8xxx Driver Download actual size!", where shoppers Lge U8xxx Driver Download may Lge U8xxx Driver Download "Take it home as soon Lge U8xxx Driver Download as Download Free Blues Music you pay for it!", and where "Merchandise may be handled prior to Lge U8xxx Driver Download purchase!".
