A Hp Free Software Download download manager is Hp Free Software Download a computer program dedicated to the task of Hp Free Software Download downloading (and sometime uploading) possibly unrelated stand-alone files from (and sometime to) the Internet for storage. This is unlike a World Wide Web browser, which is mainly intended to browse web pages, composed of a multitude of smaller Hp Free Software Download files, where error-free moving of files for permanent storage Hp Free Software Download is of secondary importance. (A Hp Free Software Download failed or Hp Free Software Download 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, Hp Free Software Download and can optionally Free Hentai Game Download split the file to be Hp Free Software Download downloaded (or uploaded) into Sandboxie Download 2 or more segments, which are Hp Free Software Download then moved in parallel, potentially making the Dvdfab Platinum Free Download process faster within the limits of the available bandwidth. (A few servers are known to block moving files in parallel segments, on the Hp Free Software Download principle that server Hp Free Software Download capacity should be shared Hp Free Software Download equally by all Hp Free Software Download users.) Multi-source is the name given Hp Free Software Download to files that are downloaded in parallel.
There are several things that some web Hp Free Software Download browsers are not very good at. That's where Hp Free Software Download the download managers enter Hp Free Software Download the equation:
Pausing the downloading of large files.
Resuming broken or Hp Free Software Download paused downloads (especially for very large Download Ad-aware Pro files).
Downloading Hp Free Software Download files on poor connections.
Downloading several files from a site automatically according Hp Free Software Download to simple rules (file types, updated files, etc. - see also Offline Browser).
Automatic recursive downloads (mirroring).
Scheduled downloads (including, automatic Hp Free Software Download hang-up Hp Free Software Download and shutdown).
Searching for mirror sites, and the handling of different connections to download 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 service provider Hp Free Software Download at night, when rates or tariffs are usually lower, download the specified files, and hang-up. They can Hp Free Software Download record which links the user clicks on during the day, and queue these files for later download. For Hp Free Software Download broadband users, download managers can help download very large files Hp Free Software Download by resuming broken downloads, by limiting Hp Free Software Download the bandwidth 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 automatically downloading Hp Free Software Download whole sites and regularly updating them (see Mirroring).
Many download managers support Metalink, an XML file listing Family Guy Blue Harvest 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 designed to download entire websites.
Download managers, such as Go!Zilla, Hp Free Software Download were among the Hp Free Software Download first adware applications displaying a banner ad in the user interface.
Related to download managers are Hp Free Software Download two other breeds of Internet programs, file-sharing peer-to-peer applications Hp Free Software Download (Kazaa, eMule, BitTorrent, Gnutella) and stream recorders (such as StreamBox VCR).
While download managers are designed to give Hp Free Software Download 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 increases Norton Win Rescue Download reliability and reduces Hp Free Software Download tech support costs to them. A possible reason is increasing the control over redistribution of their software (even when the software Hp Free Software Download is Hp Free Software Download freeware).In computer technology and telecommunication, on-line and off-line are defined Hp Free Software Download by Federal Standard 1037C. They are states or conditions of a "device or Hp Free Software Download equipment" or of "a functional unit". To be considered on-line, a device Hp Free Software Download must be at least one of:
"Under the direct control of another device"
"Under the direct control of the system with which Hp Free Software Download it is associated"
"Available for immediate use on demand by the system without human intervention"
"Connected Hp Free Software Download to a system, and is in operation"
"Functional and ready for service"
while a device that Hp Free Software Download is off-line is Hp Free Software Download 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 Hp Free Software 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 Need For Speed Se Download "on-line" it will Hp Free Software Download attempt to connect to mail servers (to check Hp Free Software Download for new mail at Hp Free Software Download regular intervals, for example), and Hp Free Software Download when it is "off-line" it Hp Free Software Download will not attempt to make 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 Hp Free Software Download the computer itself on-line, connected Hp Free Software Download to Internet via a cable modem or an ADSL connection, but may wish for Hp Free Software Download Outlook to be off-line, so that it makes no attempt to send or to receive messages. Or the Hp Free Software Download computer may be configured to employ a dial-up connection on demand (whenever an application such as Outlook Hp Free Software Download attempts to make connection to a server), but the connection may be an expensive telephone call Hp Free Software Download from the particular location Hp Free Software Download in which the computer currently happens to be (such as a Hp Free Software Download hotel room) and the user Hp Free Software Download 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 Hp Free Software Download of digital audio technology. A tape Hp Free Software Download recorder, digital editor, or Hp Free Software Download other Hp Free Software Download device that is "on-line" is one whose clock is Hp Free Software Download under the control of the clock of a "synchronization master" device. When the Hp Free Software Download sync master commences playback, the "on-line" device automatically Hp Free Software Download synchronizes itself to the Hp Free Software Download master and commences playing from Hp Free Software Download the same point in Hp Free Software Download the recording. Whereas a device that is "off-line" uses Hp Free Software Download no external clock reference and relies upon its own internal clock. When a large number of devices are connected to Hp Free Software Download a sync master, Hp Free Software Download it is often convenient, if one wants to Hp Free Software Download 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 to locate Hp Free Software Download the playback point and wait for each other to be in Hp Free Software Download synchronization.[2] Hp Free Software Download (For further related discussion, see MIDI timecode, word sync, and recording system synchronization.)
A third example Day Of The Tenticle Download of a common use of these Hp Free Software Download concepts is Hp Free Software Download a web browser that can be instructed to be in either "on-line" or Hp Free Software Download "off-line" states. The browser only attempts to fetch pages Hp Free Software Download from servers whilst in Hp Free Software Download the "on-line" state. Hp Free Software Download In the "off-line" Hp Free Software Download state, users can perform offline browsing, where pages can Hp Free Software Download be browsed using Hp Free Software Download local 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 off-line, Hp Free Software Download with connection Hp Free Software Download to Internet expensive Hp Free Software Download 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 explicitly by the browser being configured to keep local copies of certain Hp Free Software Download web Hp Free Software Download pages, which it keeps updated when the Hp Free Software 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 Hp Free Software Download explicitly configured to download pages for offline browsing is Internet Explorer. When pages are added to Hp Free Software Download the "Favourites" list, they can be marked for Hp Free Software Download being made "available for offline browsing". Internet Explorer will download to local copies both the marked page Hp Free Software Download and, optionally, all of the pages that it links to. In Internet Explorer version Hp Free Software Download 6, the level of direct and indirect links, Hp Free Software Download the maximum amount of local disc space allowed to Hp Free Software Download 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.

Offline browsing Hp Free Software Download known as "Offline favourites" was Hp Free Software Download removed as a feature in the most recent version of Internet Explorer 7, which only now supports Hp Free Software Download single web page saving, but not browsing or storing an entire site offline.[citation Hp Free Software Download needed]
Similarly, off-line storage is Hp Free Software Download computer storage that is not "available for immediate use on demand by the system without human intervention", i.e it is storage that is off-line.
The ideas of "on-line" Hp Free Software Download and "off-line" have been generalized from computing and telecommunication into the field of human interpersonal relationships. The distinction between what Hp Free Software Download is considered "on-line" and what is considered "off-line" has become a subject Hp Free Software Download 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 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 Hp Free Software Download far too simple". To support his argument that the distinctions in relationships Hp Free Software Download are more complex than Iriver Download a simple "on-line"/"off-line" dichotomy, he observes that some people draw no 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 can be regarded as an "on-line" experience in some circumstances, and that Hp Free Software Download the blurring of the distinctions between the uses of various technologies (such as PDA and mobile Hp Free Software Download telephone, Hp Free Software Download 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 pressures to reduce the distinction between Hp Free Software Download "on-line" and "off-line", with Download Movies Off Internet a Hp Free Software Download "general tendency to assimilate online to Hp Free Software Download offline and Hp Free Software Download erase Hp Free Software Download the distinction", stressing, however, that this does not mean Hp Free Software Download that on-line relationships are being reduced to pre-existing off-line relationships. He conjectures that greater legal status may be assigned to Hp Free Software Download on-line relationships Hp Free Software Download (pointing out that contractual relationships, Hp Free Software Download such as business transactions, on-line are already seen as just as "real" as their off-line counterparts), although he Hp Free Software Download states it to be hard to imagine courts awarding palimony to Hp Free Software Download people who have had a purely on-line sexual relationship. He also conjectures that an Hp Free Software Download "on-line"/"off-line" distinction may be seen Hp Free Software Download by people as "rather quaint and not quite Hp Free Software Download comprehensible" within Hp Free Software Download 10 years.[7]
The distinction where "on-line" is seen as virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used to Hp Free Software Download define and to explain "off-line" activities, Hp Free Software Download rather than (as per the Hp Free Software Download conventions of the desktop metaphor with Hp Free Software Download its desktops, trash cans, folders, and so Hp Free Software Download forth) the other way around. Several cartoons by The New Hp Free Software Download Yorker have satirized this. One Hp Free Software Download includes Saint Peter asking Hp Free Software Download for Hp Free Software Download a Hp Free Software Download user name and a password before admitting a man into Heaven. Another illustrates "the Hp Free Software Download off-line store" where "All items are actual size!", where shoppers may "Take it home as soon as you pay for Hp Free Software Download it!", and where "Merchandise may be handled Hp Free Software Download prior to purchase!".
