A download manager is Butterfly Kisses Download a computer program dedicated to the task of downloading (and sometime uploading) possibly Butterfly Kisses Download unrelated stand-alone files from (and sometime Butterfly Kisses Download 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 files, where error-free moving Butterfly Kisses Download of files for permanent storage Butterfly Kisses Download is of secondary importance. (A failed or incomplete web page file rarely ruins Butterfly Kisses Download the page.) The typical download manager at a minimum provides means to recover from errors without losing the work already completed, and can Butterfly Kisses Download optionally split the file to be downloaded (or uploaded) into 2 Butterfly Kisses Download or more segments, which are Butterfly Kisses Download then moved in parallel, potentially making the process faster within the limits of the available bandwidth. (A few Butterfly Kisses Download servers are known to block moving Butterfly Kisses Download files in parallel segments, on the principle that server capacity should Butterfly Kisses Download be shared equally by all users.) Multi-source is the name given to files that are downloaded in parallel.
There are several things that some web browsers are not very good at. That's where the download managers enter the Butterfly Kisses Download equation:
Pausing the downloading Butterfly Kisses Download of large files.
Resuming broken or paused Butterfly Kisses Download downloads (especially for very large files).
Downloading files on poor connections.
Downloading several files from a site automatically Butterfly Kisses Download 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 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 at night, when rates or tariffs are usually lower, download the specified files, Butterfly Kisses Download and hang-up. They can record which links the user clicks on during the day, and queue these files Butterfly Kisses Download for later download. For broadband 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 affected (slowed) and the server is not overloaded, or by automatically Butterfly Kisses Download navigating a site and downloading pre-specified Butterfly Kisses Download content Butterfly Kisses Download (photo galleries, MP3 collections, etc.) this can also Butterfly Kisses Download include automatically downloading whole sites and regularly updating them (see Mirroring).
Many download Butterfly Kisses Download managers support Metalink, Butterfly Kisses Download an XML file listing mirrors, checksums, and other information Butterfly Kisses Download useful for Butterfly Kisses Download downloading.
See below for some examples of commonly used download managers. Some Butterfly Kisses Download downloaders are optimized for a certain function. For example, Offline Butterfly Kisses Download Explorer is designed to download entire websites.
Download managers, such as Go!Zilla, were among the Butterfly Kisses Download first adware applications displaying a banner ad in the user Butterfly Kisses Download interface.
Related to download managers Butterfly Kisses Download are two other Butterfly Kisses Download breeds of Internet Download Sex Movies programs, file-sharing peer-to-peer applications (Kazaa, Butterfly Kisses Download eMule, BitTorrent, Gnutella) and stream recorders (such as StreamBox VCR).
While download managers Butterfly Kisses Download 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 Butterfly Kisses Download example Adobe [1], provide such downloaders for downloading Butterfly Kisses Download software on their Butterfly Kisses Download own site. Presumably Butterfly Kisses Download this increases reliability Butterfly Kisses Download and reduces tech support costs to them. Butterfly Kisses Download A possible reason is increasing the control over redistribution of their software (even when the software Butterfly Kisses Download is freeware).In computer technology and telecommunication, on-line and off-line are defined by Federal Butterfly Kisses Download Standard 1037C. Hp Officejet Drivers Download They are Butterfly Kisses Download states or conditions of a "device or equipment" or of "a functional unit". To be considered on-line, a device must be Butterfly Kisses Download at least one of:
"Under the Butterfly Kisses Download direct control of another device"
"Under the direct control of the system Butterfly Kisses Download with which it is associated"
"Available for immediate use on demand by the system without human intervention"
"Connected to a system, and is in operation"
"Functional and ready for Butterfly Kisses Download service"
while a Butterfly Kisses Download device that Butterfly Kisses Download is Butterfly Kisses Download 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 Butterfly Kisses Download of these concepts is a Mail User Agent that can be instructed to be in either "on-line" or "off-line" Butterfly Kisses Download states. Butterfly Kisses Download One such MUA is Microsoft Outlook. When it is "on-line" it will attempt to connect to Butterfly Kisses Download mail servers (to check for new mail at regular intervals, for Butterfly Kisses Download example), and when it is "off-line" it will not attempt to make Butterfly Kisses Download any such connections. The "on-line" or "off-line" state of Butterfly Kisses Download the MUA does not necessarily reflect the Butterfly Kisses Download connection status between Butterfly Kisses Download 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 Butterfly Kisses Download ADSL Butterfly Kisses Download connection, but may wish for Outlook to be off-line, so that it makes no attempt to send or to receive messages. Or the computer Butterfly Kisses Download may be Butterfly Kisses Download configured to Butterfly Kisses Download employ a dial-up Butterfly Kisses Download 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 Butterfly Kisses Download happens to be (such as a hotel Butterfly Kisses Download room) and the user may not Butterfly Kisses Download wish Outlook to trigger making that call every 5 or 10 minutes to check for mail.[1]
Another example of the use of these Anime Download Free Mp3 Music 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 Butterfly Kisses Download sync master commences playback, the "on-line" device automatically synchronizes itself to the master and commences playing Butterfly Kisses Download from the same point in the recording. Whereas a device that is "off-line" uses no external clock reference and relies upon its own internal Butterfly Kisses Download clock. When a large number of devices are connected to Butterfly Kisses Download a Butterfly Kisses Download sync Butterfly Kisses Download master, it is often convenient, if one wants to Butterfly Kisses Download hear just the output of one single device, to take it off-line, because if the device is Butterfly Kisses Download played back on-line all synchronized devices have to Butterfly Kisses Download locate the playback point and wait for each other to be in synchronization.[2] (For further related discussion, see MIDI timecode, word sync, and recording Butterfly Kisses Download system synchronization.)
A third Butterfly Kisses Download example of a common use of these concepts is a web Butterfly Kisses Download 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" 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 been downloaded Butterfly Kisses Download whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with connection Butterfly Kisses Download to Internet expensive or impossible. The pages are either downloaded implicitly into the Butterfly Kisses Download web browser's own cache, as a Free Adware Download Spyware Remove result of prior on-line browsing by the user, Butterfly Kisses Download or explicitly by the browser being configured to Butterfly Kisses Download keep local copies of certain web pages, which it keeps updated when the browser is in the on-line state, either by checking that the local copies are Butterfly Kisses Download up-to-date at Butterfly Kisses Download regular intervals Butterfly Kisses Download or by checking that the local copies are up-to-date whenever the browser is Butterfly Kisses Download switched to the on-line state. One such web browser capable Butterfly Kisses Download of being explicitly configured to download pages for offline browsing is Internet Explorer. When pages are added to Butterfly Kisses Download the Butterfly Kisses Download "Favourites" list, Butterfly Kisses Download they can be marked for being made "available for offline browsing". Internet Explorer will download to local Butterfly Kisses Download copies both the marked page and, Butterfly Kisses Download optionally, all of the pages Nfs Porsche Free Download Full Game that it links Butterfly Kisses Download to. In Internet Explorer version 6, the level of direct and indirect links, the maximum amount of local disc Butterfly Kisses Download space allowed to be consumed, and the schedule on which local copies are checked to Butterfly Kisses Download see whether they are up-to-date, are configurable for each Butterfly Kisses Download individual "Favourite" entry.

Offline browsing known as "Offline favourites" was removed as a feature in the most Butterfly Kisses Download recent version of Internet Explorer 7, which only now Butterfly Kisses Download supports single web page saving, but not browsing or storing an entire site offline.[citation Download Subliminal Music For Free needed]
Similarly, off-line storage is computer storage that is Butterfly Kisses Download not "available for immediate use on demand by the Butterfly Kisses Download system without human intervention", i.e it is storage that is off-line.
The Butterfly Kisses Download ideas of "on-line" and "off-line" have been Butterfly Kisses Download generalized from computing and telecommunication into the field of human interpersonal relationships. Butterfly Kisses Download The distinction Butterfly Kisses Download between what is considered "on-line" and what is considered "off-line" has become a subject of study in Butterfly Kisses Download the Butterfly Kisses Download field of sociology.[7]
The distinction Butterfly Kisses Download between "on-line" and "off-line" Butterfly Kisses Download is conventionally seen Butterfly Kisses Download as the distinction between computer-mediated communication Butterfly Kisses Download and face-to-face communication (e.g. Download Free Ipod Limewire Music face time), respectively. "On-line" is virtuality, and "off-line" is reality (e.g. real Butterfly Kisses Download life or meatspace). Slater states that this distinction is "obviously far too simple". To support his Butterfly Kisses Download argument that the distinctions in relationships are more complex than a simple Butterfly Kisses Download "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between an "on-line" relationship, such Butterfly Kisses Download as indulging in cybersex, and an "off-line" relationship, Butterfly Kisses Download 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 the blurring of the distinctions between the uses of various technologies (such as Butterfly Kisses Download 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 Butterfly Kisses Download that there are Butterfly Kisses Download legal Butterfly Kisses Download and regulatory pressures to reduce the distinction between "on-line" and "off-line", Butterfly Kisses Download 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. He conjectures that greater legal status may be assigned to on-line relationships (pointing out Butterfly Kisses Download that contractual relationships, such as business transactions, Butterfly Kisses Download on-line are already seen as just as "real" Butterfly Kisses Download as their off-line Butterfly Kisses Download counterparts), although he states Butterfly Kisses Download it to be Butterfly Kisses Download hard to imagine courts Butterfly Kisses Download awarding palimony to people Butterfly Kisses Download who have had a purely on-line Butterfly Kisses Download sexual relationship. He also conjectures that an "on-line"/"off-line" distinction may be seen by people as "rather quaint and not Butterfly Kisses Download quite comprehensible" within 10 years.[7]
The distinction where "on-line" is seen as virtuality and "off-line" as reality is sometimes inverted, Butterfly Kisses Download with "on-line" concepts being used to define and Butterfly Kisses Download to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash cans, folders, and so forth) the other way around. Butterfly Kisses Download Several cartoons by The New Yorker have Butterfly Kisses Download satirized this. One includes Butterfly Kisses Download Saint Peter asking for a Butterfly Kisses Download 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 may be Butterfly Kisses Download handled prior to purchase!". |
