A download manager is a computer Download Psp Games program dedicated Download Psp Games to the task of Download Psp Games downloading (and sometime uploading) possibly unrelated stand-alone files from (and sometime to) the Internet for storage. This is unlike Download Psp Games a World Wide Web browser, which is mainly intended to browse web pages, composed of a multitude of smaller files, where Download Psp Games error-free moving of files for permanent storage Download Psp Games is of secondary Download Psp Games importance. (A failed or incomplete web page file rarely ruins the page.) The typical Download Psp Games download manager at a minimum provides means to recover Download Psp Games from errors without losing the work already completed, and can optionally split the file to be downloaded (or uploaded) into 2 or more segments, which are Download Psp Games then moved in parallel, potentially making Download Psp Games the Download Psp Games 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 Download Psp Games equally by all users.) Multi-source is the name given to files that are Download Psp Games downloaded in parallel.
There are several things Download Psp Games that some web browsers Download Psp Games are not very good at. That's where the download managers Download Direct X 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 Download Psp Games files from Download Psp Games a site automatically according to Download Psp Games simple rules (file types, updated Download Psp Games files, etc. - see also Offline Browser).
Automatic recursive downloads Mcafee Download (mirroring).
Scheduled downloads (including, automatic hang-up and shutdown).
Searching for mirror sites, and the handling of different connections to download Download Psp Games the same file more quickly (segmented downloading).
Download managers are useful for active Internet users. For dial-up users, they can automatically dial the internet Download Psp Games service provider at night, when rates or tariffs are usually lower, download the Download Psp Games specified files, and hang-up. They can record which links the user Download Psp Games clicks Download Psp Games on during the day, and queue these files for later download. For broadband Download Psp Games 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 Psp Games affected (slowed) and the server is not overloaded, or by automatically navigating a Download Psp Games site Microsoft Paint Download and downloading pre-specified content (photo galleries, Download Psp Games MP3 collections, etc.) this can also include automatically downloading whole sites and regularly Download Psp Games updating Download Psp Games them (see Mirroring).
Many download managers support Metalink, an XML file listing mirrors, checksums, and other information useful Download Psp Games 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 entire websites.
Download managers, such as Go!Zilla, were among Download Psp Games the first adware applications displaying a banner ad in the user interface.
Related to download managers are two Bittorrent Download other breeds of Internet Download Psp Games programs, file-sharing peer-to-peer applications Download Psp Games (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 control to content distributors instead. Some software companies, for example Adobe [1], provide such downloaders for downloading software on their own site. Presumably this Download Psp Games increases reliability and reduces tech support costs to them. A Download Psp Games possible reason is increasing the control over Download Psp Games redistribution Download Psp Games of their software (even when the software Download Psp Games is freeware).In computer technology and Download Psp Games telecommunication, on-line and off-line are defined by Federal Standard 1037C. They are states or conditions of a "device or equipment" or of "a functional unit". Download Psp Games To be considered on-line, a device must be at least one of:
"Under the direct control of another device"
"Under the direct control of the system with which it is associated"
"Available for immediate Download Psp Games use on demand by the system without human intervention"
"Connected to a system, Download Psp Games and is in operation"
"Functional and ready for service"
while a device 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 use of these concepts is a Mail User Download Psp Games Agent that can be instructed to be in either "on-line" or "off-line" states. One such MUA Download Psp Games is Microsoft Outlook. When it is "on-line" it will attempt to connect to Download Psp Games mail servers (to check for Download Psp Games new mail at regular Download Psp Games intervals, for example), and Download Psp Games when it is "off-line" it will not attempt to make Download Psp Games any such connections. The "on-line" or "off-line" state of the MUA does Download Psp Games not necessarily Download Psp Games reflect the connection status Download Psp Games between the computer Download Psp Games on Download Psp Games 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, Download Psp Games but may wish for Outlook to be off-line, Download Psp Games so Download Psp Games that it makes no attempt to send or Download Psp Games 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 to a server), but the connection may be an expensive telephone call 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 that call every 5 or 10 minutes to check for mail.[1]
Another example of the use of these concepts is in Download Psp Games the world of digital audio technology. A tape recorder, digital editor, or other device that is "on-line" is one Download Psp Games whose clock Download Royalty Free Music is under the control of the clock of Download Psp Games 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 Download Psp Games upon its own internal clock. When Desktop Calendars Free Download a large Download Psp Games number of devices are connected to a Download Psp Games sync master, it is often convenient, if Download Psp Games one wants to hear just the output of one single device, to take it off-line, because if the Download Free Vcd Movie device is played back on-line all Download Psp Games synchronized devices have to locate the Download Psp Games playback point and wait for each other Download Psp Games 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 these concepts is a web browser that Download Psp Games can be Download Psp Games instructed to be in either "on-line" or "off-line" Download Psp Games states. The browser only attempts to fetch pages Download Psp Games from servers Download Psp Games whilst in the "on-line" state. In the "off-line" state, users can perform offline browsing, where pages can be browsed using local copies of those pages that have previously Download Psp Games been downloaded whilst Download Psp Games in Download Psp Games the "on-line" Download Psp Games state. This can be useful when the computer itself is Download Psp Games also off-line, with Download Psp Games connection to Internet Download Psp Games expensive or impossible. The pages Download Psp Games are either downloaded implicitly into the web browser's own cache, as a result of prior on-line browsing by the user, or explicitly by the browser being configured to Download Psp Games keep Download Psp Games local copies Download Psp Games of certain The Sims Download web pages, Download Psp Games which it keeps updated when the browser is in the on-line state, either by checking that the local Download Psp Games copies are up-to-date at regular Download Psp Games intervals or by checking that the local copies are up-to-date whenever the browser is switched Download Psp Games to the on-line state. One such web browser capable of being explicitly configured to Download Psp Games 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, all of the pages that it links to. Download Psp Games In Internet Explorer version 6, the level of direct and indirect links, the Download Psp Games maximum amount of local disc space allowed to Download Psp Games be consumed, and the schedule on which local copies are checked to see whether they are up-to-date, Download Psp Games are configurable for each individual "Favourite" entry.

Offline browsing known as "Offline favourites" was removed Download Psp Games as a feature in Download Psp Games the most recent version of Internet Explorer 7, which only now supports single Download Psp Games web page saving, but not browsing or storing Download Psp Games an entire site offline.[citation Download Psp Games needed]
Similarly, Download Psp Games off-line storage is computer storage that Download Psp Games is not Download Psp Games "available for immediate use Download Psp Games on demand by the system without human Download Psp Games intervention", i.e it is storage that is off-line.
The ideas Download Psp Games of "on-line" and "off-line" have been generalized from computing and telecommunication into the field Download Psp Games of human interpersonal relationships. The distinction between what is considered "on-line" and what is considered "off-line" has Download Psp Games become a subject of study in the field of sociology.[7]
The distinction between "on-line" and "off-line" Download Psp Games is conventionally seen Download Psp Games as the distinction between computer-mediated communication Download Psp Games and face-to-face communication (e.g. face time), respectively. "On-line" Download Psp Games is virtuality, and "off-line" is reality (e.g. real life or meatspace). Slater states that this distinction is "obviously far too simple". To Download Psp Games support his argument that the Download Psp Games distinctions in relationships are more complex than a simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between an Download Psp Games "on-line" relationship, such as indulging in cybersex, and an "off-line" relationship, such as being pen-pals. Download Psp Games He also argues that even the Download Psp Games telephone can be 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 telephone and voice-over-IP) Download Psp Games has Download Psp Games made it "impossible Download Psp Games to use the term 'on-line' meaningfully in the sense that was employed by the first generation of Internet research".[7]
Slater asserts that Download Psp Games there are Download Psp Games legal and regulatory pressures Download Psp Games 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. Download Psp Games He conjectures that greater Download Psp Games legal status may be assigned to on-line relationships (pointing out that contractual relationships, such as business transactions, Download Psp Games on-line are already seen as just as "real" as their off-line Download Psp Games counterparts), although he states it to be hard to imagine courts Download Psp Games awarding palimony to people who have had a purely on-line sexual relationship. He Download Psp Games also conjectures that an "on-line"/"off-line" distinction may be seen Download Psp Games by people as "rather quaint and not quite comprehensible" within 10 years.[7]
The distinction where "on-line" is seen as virtuality Download Psp Games and Download Psp Games "off-line" as Download Psp Games reality is sometimes inverted, with Download Psp Games "on-line" concepts being used to define Download Psp Games and to explain "off-line" activities, rather than (as Download Psp Games per the conventions of the desktop metaphor with Download Psp Games its desktops, trash cans, folders, and so forth) the other way around. Several cartoons by The New Yorker have satirized Download Psp Games this. One includes Download Psp Games Saint Peter asking for Download Psp Games a user name and a password before admitting a man into Heaven. Another illustrates "the off-line store" where "All items are actual size!", where shoppers may "Take it home as soon as you pay for it!", and where "Merchandise Free Download For Linux may be handled prior to purchase!". |
