A download manager is a computer program dedicated to the task of Emule Plus Download downloading (and Emule Plus Download sometime uploading) Emule Plus Download possibly unrelated stand-alone files Emule Plus Download from (and Emule Plus Download sometime to) the Internet for storage. This is unlike a World Wide Web browser, which Emule Plus Download is mainly Emule Plus Download intended to browse web pages, composed of a multitude Emule Plus Download of smaller files, where error-free moving of files for permanent storage is of secondary importance. (A Emule Plus Download failed or incomplete web page file rarely ruins the Emule Plus Download page.) The typical download manager at a 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 Emule Plus Download or more segments, which are then moved in parallel, Emule Plus Download 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 Emule Plus Download server capacity should Emule Plus Download be shared equally by all users.) Multi-source is the Emule Plus Download name given to files that are Emule Plus Download downloaded in parallel.
There Emule Plus Download are several Emule Plus Download 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 for very large files).
Downloading files on poor connections.
Downloading several files from a site automatically according Emule Plus Download to simple rules (file types, updated files, etc. Emule Plus Download - see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, automatic hang-up and shutdown).
Searching for Warcraft Free Download mirror sites, and the handling of different connections to download the same file more quickly (segmented downloading).
Download managers Poweriso Download are useful Emule Plus Download 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 Emule Plus Download the specified files, and hang-up. They can record which links the user clicks on during the day, and queue these files Emule Plus Download for later download. For broadband users, download managers can help download very large files by resuming broken downloads, by limiting the bandwidth used, Emule Plus Download so Emule Plus Download that other internet activities are not affected (slowed) Emule Plus Download 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 Emule Plus Download downloading whole sites and regularly updating them (see Emule Plus Download Mirroring).
Many download managers Emule Plus Download support Metalink, an XML file listing mirrors, checksums, and other information Emule Plus Download useful for downloading.
See below for some examples of commonly used download managers. Some downloaders are optimized for a certain function. For example, Offline Explorer is designed to download Emule Plus Download entire websites.
Download managers, Emule Plus Download such as Go!Zilla, were among Emule Plus Download the first adware applications Emule Plus Download displaying a banner ad in the Emule Plus Download user interface.
Related to download managers are two other Download Vlc breeds of Emule Plus Download Internet programs, Emule Plus Download file-sharing peer-to-peer applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such as Emule Plus Download StreamBox VCR).
While download managers are designed to give users greater control over Emule Plus Download downloads, some downloaders are created to give that control to content distributors instead. Some software companies, for example Adobe [1], Emule Plus Download provide Emule Plus Download such downloaders for downloading software on Emule Plus Download their own site. Presumably this increases reliability and reduces tech support costs to them. A Emule Plus Download possible reason is increasing the control over redistribution of their Emule Plus Download software Emule Plus Download (even when the software is freeware).In computer technology Emule Plus Download and telecommunication, on-line and off-line are defined by Emule Plus Download Federal Standard 1037C. They are states or conditions of a "device or equipment" or of "a functional unit". Emule Plus Download To be considered on-line, a device must be at least one of:
"Under the direct Emule Plus 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 Emule Plus Download without human intervention"
"Connected to a system, and Emule Plus Download is in operation"
"Functional and ready for service"
while a device that is off-line is not (e.g. it has Emule Plus Download "its main Emule Plus Download power source disconnected or turned off", and is "off-power").
One example of a common Emule Plus Download use of these concepts Emule Plus Download 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 Emule Plus Download "on-line" it will attempt to connect to mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" it will not attempt to make Emule Plus Download 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 Emule Plus Download the computer itself Emule Plus Download on-line, connected to Internet via a cable Emule Plus Download modem or an ADSL Emule Plus Download connection, but may wish for Outlook to be off-line, so that it makes no attempt to send Download Win Xp Sp2 or to receive messages. Or Emule Plus Download the computer may be configured to employ a dial-up connection on demand (whenever an application such as Emule Plus Download Outlook attempts to Emule Plus Download make connection to a server), but the connection may be an expensive telephone call from the particular location in which the computer Emule Plus Download currently happens to be (such as a hotel room) and the user may not wish Outlook to trigger making that call every 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 tape Emule Plus Download recorder, digital editor, or other device that is "on-line" is one whose clock is under the control of the clock of Emule Plus Download 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 Emule Plus Download own internal clock. When a large number of devices are Emule Plus Download connected to a Emule Plus Download sync master, Emule Plus Download it is often convenient, if one wants to hear just the output of one single Emule Plus Download device, to take it off-line, because if the device is played back on-line all synchronized devices Emule Plus Download have to locate the playback point and wait for each other to be in synchronization.[2] (For Emule Plus Download further related discussion, see MIDI timecode, word sync, and recording system synchronization.)
A third example of a common use of these concepts Emule Plus Download 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" Emule Plus Download state. In the "off-line" state, users can perform offline browsing, where pages can be browsed using local Emule Plus Download copies of those pages that have Emule Plus Download previously been downloaded whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with connection to Internet expensive or impossible. The pages are either downloaded implicitly into Emule Plus Download the web browser's own cache, as a result of prior on-line browsing Emule Plus Download by the user, or explicitly by the browser being configured Emule Plus Download to keep local copies of certain web pages, which it keeps updated when the browser is in the on-line Emule Plus Download state, either by checking Emule Plus Download that the local copies are up-to-date at regular intervals Emule Plus Download or by checking that the local copies are Emule Plus Download up-to-date whenever Emule Plus Download the browser is switched to the Emule Plus Download on-line state. One such Emule Plus Download web browser capable of being explicitly configured to download Emule Plus Download pages for offline browsing Emule Plus Download is Internet Explorer. When pages are added to the "Favourites" list, Emule Plus Download they can be Emule Plus Download marked for being made "available for Emule Plus Download offline browsing". Internet Explorer Emule Plus Download will download to Emule Plus Download local copies both the marked page and, optionally, all of the pages that it links to. In Internet Explorer version 6, the level of direct Emule Plus Download and indirect links, the maximum amount of local disc space allowed to Download Episode Free Simpsons be consumed, and the schedule on which local copies are checked Emule Plus Download to Emule Plus Download see whether they are up-to-date, are configurable for each individual "Favourite" entry.

Offline Emule Plus Download browsing known as "Offline favourites" was removed as a feature in the most recent version of Internet Explorer 7, which Emule Plus Download only Emule Plus Download now supports single web page saving, but not browsing or storing an entire Emule Plus Download site offline.[citation needed]
Similarly, off-line Emule Plus Download storage is computer storage that is not "available for Emule Plus Download immediate use on demand by the system without Emule Plus Download human intervention", Emule Plus Download i.e it is storage that is Emule Plus 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. Emule Plus Download The distinction between Emule Plus Download 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 Emule Plus Download 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 Emule Plus Download too simple". To support his argument that the Emule Plus Download distinctions in relationships are more complex than a simple Emule Plus Download "on-line"/"off-line" dichotomy, he observes that some people draw no Emule Plus Download distinction between an "on-line" relationship, such as indulging in cybersex, and an "off-line" relationship, such as being pen-pals. He also argues that even the telephone Emule Plus Download can be regarded as an "on-line" experience in some circumstances, and that the blurring of the Emule Plus Download distinctions between the uses of Emule Plus Download various Emule Plus Download technologies (such as PDA and mobile telephone, Emule Plus Download television and Internet, Emule Plus Download and telephone and voice-over-IP) has made it "impossible to use Emule Plus Download the term 'on-line' meaningfully in the sense that Emule Plus Download 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 tendency to assimilate online to offline and erase the distinction", stressing, however, that this does not Emule Plus Download mean that on-line relationships are being reduced to pre-existing off-line relationships. He Emule Plus Download conjectures that greater legal status may Emule Plus Download be assigned to on-line relationships (pointing out that contractual relationships, such Emule Plus Download as business transactions, on-line are already seen as just as "real" Emule Plus Download 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 Emule Plus Download sexual relationship. He also conjectures that an "on-line"/"off-line" distinction may be seen by people as Emule Plus Download "rather Emule Plus Download quaint and not quite Emule Plus Download comprehensible" within 10 years.[7]
The distinction where "on-line" is seen as virtuality and Emule Plus Download "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 of the desktop metaphor with its desktops, Emule Plus Download 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 Emule Plus Download user name and a Emule Plus Download password before Emule Plus Download admitting a man into Heaven. Another illustrates "the Emule Plus Download off-line store" where "All items are actual size!", where shoppers Emule Plus Download may "Take Emule Plus Download it Emule Plus Download High School Musical Download Free home as soon as you pay for it!", and where "Merchandise may be handled prior to purchase!". |
