A download manager is a computer program dedicated to the task of downloading (and sometime Programi Za Download Glasbe uploading) possibly unrelated Programi Za Download Glasbe stand-alone files from (and sometime to) the Internet for storage. This is unlike a World Wide Web browser, Programi Za Download Glasbe which is mainly intended to browse web pages, composed of a multitude of smaller files, where error-free Programi Za Download Glasbe moving Programi Za Download Glasbe 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 means to recover from errors without losing the work already completed, and can optionally split the file to be downloaded (or Programi Za Download Glasbe uploaded) into 2 or more Windows Vista Download segments, which are then Free Dvd Software Download moved in parallel, potentially making the Programi Za Download Glasbe process faster within the limits of the available bandwidth. (A few servers are Programi Za Download Glasbe known to block Programi Za Download Glasbe moving files in parallel segments, on the principle that server capacity should be shared equally by all users.) Multi-source is Programi Za Download Glasbe the name given to files Programi Za Download Glasbe that are Programi Za Download Glasbe downloaded Programi Za Download Glasbe in parallel.
There are several things that some web browsers are not very good at. That's where Programi Za Download Glasbe the download managers enter the Programi Za Download Glasbe equation:
Pausing the downloading of large files.
Resuming broken or paused downloads (especially for very large files).
Downloading files on poor connections.
Downloading several Programi Za Download Glasbe files from a site automatically according to simple rules (file Programi Za Download Glasbe types, updated files, etc. - see also Offline Programi Za Download Glasbe Browser).
Automatic Programi Za Download Glasbe 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 managers Programi Za Download Glasbe are useful for active Programi Za Download Glasbe Internet Programi Za Download Glasbe 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 hang-up. They can record which links the user clicks on during the day, and queue these files for later download. For broadband users, download managers can help download very large files by resuming Programi Za Download Glasbe broken Programi Za Download Glasbe downloads, Programi Za Download Glasbe by limiting the bandwidth Programi Za Download Glasbe used, so that other internet activities are not 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 Gimp Download automatically downloading Download Windows System File whole sites and regularly updating them Programi Za Download Glasbe (see Mirroring).
Many download managers support Metalink, an Mp3 Glasba Free Download XML file listing Programi Za Download Glasbe mirrors, checksums, and other information useful for downloading.
See below for some Programi Za Download Glasbe examples of commonly used download managers. Some downloaders are optimized for a certain function. Programi Za Download Glasbe For example, Offline Explorer is designed to download entire websites.
Download managers, such as Go!Zilla, Programi Za Download Glasbe were among the Programi Za Download Glasbe first adware applications displaying a banner ad in the user interface.
Related to download managers are two other breeds of Internet programs, Programi Za Download Glasbe file-sharing peer-to-peer Programi Za Download Glasbe applications (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such as StreamBox VCR).
While download managers are Programi Za Download Glasbe designed to give users greater control over downloads, some downloaders are created Programi Za Download Glasbe to give that control to content distributors instead. Some software companies, for example Adobe [1], provide Programi Za Download Glasbe such downloaders for Programi Za Download Glasbe downloading software on their own site. Programi Za Download Glasbe Presumably Programi Za Download Glasbe this Programi Za Download Glasbe 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 off-line are defined by Federal Standard 1037C. They are states or conditions of a "device Programi Za Download Glasbe or equipment" or of "a functional unit". To Programi Za Download Glasbe be considered on-line, a device Programi Za Download Glasbe must be at least one Programi Za Download Glasbe of:
"Under the direct control of another device"
"Under the direct control of the system with which it is associated"
"Available for immediate use on Programi Za Download Glasbe demand by Avast Download the Programi Za Download Glasbe system without human intervention"
"Connected to a system, and is Programi Za Download Glasbe in operation"
"Functional and ready for service"
while a Programi Za Download Glasbe device that is off-line is not (e.g. it Programi Za Download Glasbe has "its main power source disconnected or turned off", and Programi Za Download Glasbe is "off-power").
One Programi Za Download Glasbe example of a common use of these concepts is a Mail User Agent that can be instructed Programi Za Download Glasbe 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 Programi Za Download Glasbe connect to mail servers Programi Za Download Glasbe (to check for new mail at Programi Za Download Glasbe regular intervals, for example), and Programi Za Download Glasbe when it is "off-line" it will not Programi Za Download Glasbe attempt to make any such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect Programi Za Download Glasbe the connection status between Programi Za Download Glasbe the computer on which it Programi Za Download Glasbe is running and Internet. The user may have the computer itself on-line, connected to Internet via Programi Za Download Glasbe a cable modem or an ADSL connection, but may wish for Outlook to Programi Za Download Glasbe be off-line, so that it makes no attempt to send or to receive Programi Za Download Glasbe 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 to a server), but the connection may be an expensive telephone call from the Programi Za Download Glasbe particular location in which the computer currently happens to be (such as a hotel Programi Za Download Glasbe room) and the user may not wish Programi Za Download Glasbe Outlook to trigger making that call every 5 Programi Za Download Glasbe or 10 minutes to check for mail.[1]
Another example of the use of Programi Za Download Glasbe these concepts is in the Programi Za Download Glasbe world of digital audio technology. A tape recorder, digital editor, or other device that Programi Za Download Glasbe is "on-line" is one whose Programi Za Download Glasbe clock is under the control of the clock Download Titanic Film of a "synchronization master" device. When the sync master commences playback, the Programi Za Download Glasbe "on-line" device automatically synchronizes itself to the master and commences playing from Programi Za Download Glasbe 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 large number of devices are connected to a sync master, it 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 on-line all synchronized devices have Programi Za Download Glasbe to locate the playback Programi Za Download Glasbe point and wait for Programi Za Download Glasbe each Programi Za Download Glasbe other to be in synchronization.[2] (For further related discussion, see MIDI timecode, word sync, and recording system synchronization.)
A third example of a common use of Programi Za Download Glasbe these concepts is a web browser that can be instructed to be in either "on-line" or Programi Za Download Glasbe "off-line" states. The browser only Programi Za Download Glasbe attempts to fetch pages Programi Za Download Glasbe from servers whilst in the Programi Za Download Glasbe "on-line" state. In the "off-line" state, users Programi Za Download Glasbe can perform offline browsing, where pages can be browsed using local copies Programi Za Download Glasbe of those pages Programi Za Download Glasbe that have Programi Za Download Glasbe previously been downloaded whilst in the "on-line" Programi Za Download Glasbe state. This Programi Za Download Glasbe can be useful when the computer itself is also off-line, with connection to Programi Za Download Glasbe 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, Programi Za Download Glasbe or Programi Za Download Glasbe explicitly by Programi Za Download Glasbe the browser being configured to keep local copies of certain web Programi Za Download Glasbe pages, which it keeps updated when the 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 Programi Za Download Glasbe browser capable of being explicitly Programi Za Download Glasbe configured to download pages for offline browsing is Internet Explorer. When pages Programi Za Download Glasbe are added to the "Favourites" list, Programi Za Download Glasbe they can be marked for being made "available for offline browsing". Internet Explorer Programi Za Download Glasbe will download to local copies both the marked page and, optionally, all of the pages that it links to. Programi Za Download Glasbe In Internet Programi Za Download Glasbe Explorer version 6, the level of direct and indirect links, the maximum amount of local disc Programi Za Download Glasbe space allowed to be consumed, and the schedule on which local copies are checked to see whether Programi Za Download Glasbe they Programi Za Download Glasbe are up-to-date, are configurable for each Programi Za Download Glasbe individual Programi Za Download Glasbe "Favourite" entry.

Offline browsing known as "Offline favourites" was removed as a feature in the most recent version of Internet Explorer 7, which only now supports single web page Programi Za Download Glasbe saving, but not browsing or storing an entire site offline.[citation needed]
Similarly, off-line storage is Programi Za Download Glasbe computer storage that is Programi Za Download Glasbe not "available for immediate use Programi Za Download Glasbe on demand by the Programi Za Download Glasbe system without Programi Za Download Glasbe human intervention", i.e it is storage that is off-line.
The Programi Za Download Glasbe ideas of "on-line" and Programi Za Download Glasbe Yu-gi-oh Igra Download "off-line" have been Programi Za Download Glasbe generalized from computing and telecommunication Programi Za Download Glasbe into the field of human interpersonal relationships. The distinction between what is considered "on-line" and what is considered "off-line" has become a Programi Za Download Glasbe 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 communication and Programi Za Download Glasbe face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, and "off-line" is reality (e.g. real Programi Za Download Glasbe life or meatspace). Slater states that this distinction is "obviously far too simple". Programi Za Download Glasbe To support his Programi Za Download Glasbe argument that the distinctions in relationships are more complex than a simple Programi Za Download Glasbe "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between an Programi Za Download Glasbe "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 can be Programi Za Download Glasbe regarded as 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 Programi Za Download Glasbe telephone and voice-over-IP) Download Office 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 Programi Za Download Glasbe regulatory pressures to Microsoft Activex Free Download reduce Programi Za Download Glasbe the distinction between "on-line" and "off-line", Pes Download with a "general tendency to assimilate online to Programi Za Download Glasbe 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 be assigned to on-line relationships (pointing out that Excite Chat Download contractual relationships, such as business transactions, on-line are already seen as just Programi Za Download Glasbe as "real" as their off-line counterparts), although he states Programi Za Download Glasbe it Programi Za Download Glasbe to be hard to imagine courts awarding palimony to people who Programi Za Download Glasbe have had a purely on-line Programi Za Download Glasbe sexual relationship. He also conjectures that an "on-line"/"off-line" distinction may Programi Za Download Glasbe be seen by people as "rather quaint and not quite comprehensible" within 10 years.[7]
The distinction where "on-line" Hamachi Download is seen as virtuality and "off-line" as reality is sometimes inverted, with "on-line" Programi Za Download Glasbe concepts Programi Za Download Glasbe being used to define and to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash Programi Za Download Glasbe 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 name Direkt X Vista Download and a Programi Za Download Glasbe password before admitting a man into Heaven. Another illustrates "the off-line Programi Za Download Glasbe store" where "All items are actual size!", where shoppers may "Take Programi Za Download Glasbe it home as soon as you pay for it!", and where "Merchandise may be Download Vista Sp1 handled prior to purchase!". |
