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 World Poweriso Download Wide Web browser, which is mainly intended to browse web pages, composed of a multitude of smaller files, where error-free moving Poweriso Download of files for permanent storage is Poweriso Download of secondary importance. (A failed or incomplete web Poweriso Download page file rarely ruins the page.) The typical download manager at a minimum provides Poweriso Download means to recover Poweriso Download from errors without losing the work Poweriso Download already completed, and can optionally split the file to be Poweriso Download downloaded (or uploaded) into 2 or more segments, which are then moved in parallel, potentially making Poweriso Download the process faster Poweriso Download within the limits of the available bandwidth. (A few servers are known to block moving files Poweriso Download in parallel segments, on the principle that server Free Download Calendars capacity should be shared equally by all users.) Multi-source is the name given to files Poweriso Download that are downloaded in Poweriso Download parallel. There are several things that some web browsers are not very Poweriso Download good at. That's where Poweriso Download the download managers enter the equation: Pausing the downloading of large Poweriso Download files. Resuming broken or paused downloads (especially Poweriso Downloadfor very large files). Downloading files on poor connections. Downloading several files from a Poweriso Download site automatically 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 mirror sites, and the handling of Poweriso Download different connections to download the same file more quicklyPoweriso Download(segmented downloading). 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 usuallyPoweriso Downloadlower, download the Poweriso Download specified files, and hang-up. They can record which links the user clicks on during the day, and queue Poweriso Download these files for later download. For Poweriso Download broadbandPoweriso Downloadusers, download managers Poweriso Download can help download very large files by resuming broken downloads, by Poweriso Download limiting the bandwidth used, soPoweriso Downloadthat other internet activities are not affected (slowed) and the server is not overloaded, or by automatically Poweriso Download navigating a site and downloading pre-specified content (photo galleries, MP3 collections, etc.) this can also include automatically downloading whole sites and regularly updating them (see Mirroring). Many download managers support Metalink, an XML file listing Poweriso Download mirrors, checksums, and other information 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 Poweriso Download designed to download entire websites. Download managers, such Poweriso Download as Go!Zilla, were among Poweriso Download the first adware applications displaying a banner ad in the user interface. Related to 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 Poweriso Download greater control over downloads, some Poweriso Download downloaders are created to give that Poweriso Download control to Poweriso Download content distributors instead. Some software companies, for example Adobe [1], provide such downloaders for downloading software on their own site. Presumably this increases reliability and reduces tech Poweriso Download support costs to them. Poweriso Download A Poweriso Download possible reason is increasing the control over redistribution of their software (even when the software is freeware).In computer technology and telecommunication, on-line Poweriso Download and off-line are defined by Federal Standard 1037C. They are states or conditions of a "device or Poweriso Download equipment" or Poweriso Download of "a functional unit". To be Poweriso Download considered on-line, a device must be at least Poweriso Download one of: "Under the direct control of another device" "Under the direct Poweriso Download control of the system with which it Poweriso Download is associated" "Available for immediate use on demand by the Poweriso Download system without human intervention" "Connected to a system, and is in operation" "Functional and ready Poweriso Download for service" while a device that is off-line isPoweriso Downloadnot (e.g. it has "its main power source Poweriso Download disconnected Poweriso Download or turned off", and is "off-power"). One example of Poweriso Download a Poweriso Download common use of these concepts is Poweriso Download a Mail User Agent that can be instructed to be in either "on-line" or "off-line" states. One such Poweriso Download MUA is Microsoft Outlook. When it Poweriso Download is "on-line" it will attempt to Poweriso Download connect to mail servers (to check for new mail Poweriso Download at Poweriso Download regular intervals, for example), and Download Dbz Rpg when it is "off-line" it will not attempt Poweriso Download to make any such connections. The "on-line" or Poweriso Download "off-line" state of the MUA does not necessarily reflect the Poweriso Download connection status between the computer on which it is running and Internet. The user may have the computer itself on-line, connected to Internet via a cable modem or an ADSL connection, but may wish for Poweriso Download Outlook to be off-line, so that it makes no attempt to send or to receive messages. Or thePoweriso Downloadcomputer may be configuredPoweriso Downloadto employ a dial-up connection on demand (whenever an application Poweriso Download such as Outlook attempts to make connection to a server), but the connection may be an expensive telephone call from the particular Poweriso Download location in which the computer currently Poweriso Download happens to be Poweriso Download (such as Poweriso Download a hotel room) and the user may not wish Outlook to trigger Poweriso Download making that call every 5 Poweriso Download or 10 minutes Poweriso Download to check for mail.[1] Another example of the use of Poweriso Download these concepts is 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 the clock of a "synchronization master" device. When the sync master Poweriso Download commences playback, the "on-line" device automatically synchronizes itself Undisputed Mp3 Download Bring It On to the master and commences playing from the same point in the recording. Whereas a device that Poweriso Download is "off-line" uses no external Poweriso Download clock reference and relies upon its Poweriso Download own internal clock. When a large number of devices are Poweriso Download connected to a sync master, it Poweriso Download is often convenient, if one wants to hear just the output of one single device, to take it off-line, because if the device is played back Poweriso Download on-line all synchronized devices have to locate the playback point and wait forPoweriso Downloadeach other to be in synchronization.[2] Sabayon Download (For Poweriso Download further related Poweriso Download discussion, see MIDI timecode, word sync, and recording Poweriso Download system synchronization.) A third example of a common use of these concepts is a web browser that can be instructed Poweriso Download to be in either "on-line" or "off-line" Poweriso Download states. The browser only attempts to fetch Poweriso Download pages from servers whilst Poweriso Download in the "on-line" state. In the "off-line" state, Poweriso Download users can perform offline Poweriso Download browsing, where pages can Poweriso Download be Poweriso Download browsed using local Poweriso Download copies of those pages that have previously been downloaded whilst in the "on-line" state. This can be useful when the computer itself is also Poweriso Download off-line, with connection to Internet expensive or impossible. The pages are either downloaded implicitly into the web browser's own cache, as a result of prior on-line browsing by the user, or explicitlyPoweriso Downloadby Dsj Download the browser being configured to keep local copies of certain web pages, which it keeps updated when the Poweriso Download browser is in the on-line state, 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 the on-line state. 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 copies both the marked page and, optionally,Poweriso Downloadall of the Poweriso Download pages Poweriso Download that it links to. In Internet Poweriso Download Explorer version 6, the level of direct and Poweriso Download indirect links, the maximum amount of Poweriso Download local disc space allowed to be consumed, and the schedule on which local copies are checked to see whether they are up-to-date, are configurable for each individual "Favourite" entry. See also: Offline browsing known as "Offline favourites" wasPoweriso Downloadremoved as a feature in the mostPoweriso Downloadrecent version of Internet Explorer 7, which onlyPoweriso Downloadnow supports single web page saving, but not browsing or storing an entire site offline.[citation needed] Similarly, off-line storage is Poweriso Download computer storage that is not "available for immediate use on demand Poweriso Download by the system without human intervention", i.e it 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 Poweriso Download "on-line" and what is considered Poweriso Download "off-line" Shareaza Download 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 Poweriso Download computer-mediated communication and face-to-face Poweriso Download communication (e.g. face time), respectively. "On-line" is virtuality, Rpgmaker2000 Game Download 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 Poweriso Download than a simple "on-line"/"off-line" dichotomy, he observes that some people draw no Poweriso 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 evenPoweriso Downloadthe telephonePoweriso Downloadcan be regarded as an Poweriso Download "on-line" experience in some circumstances, and that the blurring of the distinctions Poweriso Download between the uses of various technologies (such as PDA and mobile telephone, television and Internet, and telephone and voice-over-IP) has made it "impossible to use the term 'on-line' meaningfully in the sense that was employed by the first generation of Internet research".[7] Slater asserts that there are legal and regulatory Poweriso Download pressures to reduce the distinction between "on-line" and "off-line", with a "general tendency to assimilate Poweriso Download online to offline and Poweriso Download erase the distinction", stressing, however, that this does Poweriso Download 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 Poweriso Download out that contractual relationships, such as business transactions, on-linePoweriso Downloadare already Poweriso Download seen as just as "real" as their off-line Free Web Browsers Download counterparts), although he states it to be hard to imagine courts awarding palimony Poweriso Download 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 as "rather quaint and not quite comprehensible" within 10 years.[7] The distinction Free Shareaza Download where "on-line" is seenPoweriso Downloadas virtuality and "off-line" as reality is sometimes inverted, with "on-line" Poweriso Download concepts being used to define and Poweriso Download to explain "off-line" Poweriso Download activities, rather than (as per the conventions of the Poweriso Download desktop metaphor with Poweriso Download its desktops, trash Warcraft Free Download cans, folders, Poweriso Download and so forth) Poweriso Download the other way around. Several cartoons by The New Yorker have satirized this. One includes Saint Peter asking for Poweriso Download a user Poweriso Download name and a password before admitting a man into Heaven. Another illustrates "the off-line Poweriso Download store" where "All items are actual size!", where shoppers may "Take Poweriso Download it home as soon as you pay for it!", and where "Merchandise may be handled prior to purchase!".
