A download manager is a computer program dedicated Day Of The Tenticle Download to the task of downloading (and sometime uploading) possibly Day Of The Tenticle Download unrelated stand-alone files from Day Of The Tenticle Download (and sometime to) the Internet for storage. This is unlike a World Day Of The Tenticle Download Wide Web browser, which is mainly intended to browse web pages, composed of a multitude of smaller files, where error-free moving of Day Of The Tenticle Download files for permanent storage is of secondary importance. (A failed Day Of The Tenticle Download 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 Day Of The Tenticle Download work already completed, and can Day Of The Tenticle Download optionally split the file to be downloaded (or uploaded) into Day Of The Tenticle Download 2 or more segments, which are then moved in parallel, potentially making the process faster within the limits of the available bandwidth. (A few Day Of The Tenticle Download servers are Day Of The Tenticle Download known to block moving files in parallel segments, on the principle that server capacity should be shared Sandboxie Download equally by all users.) Multi-source is the Day Of The Tenticle Download name given to files Day Of The Tenticle Download that are Day Of The Tenticle Download downloaded in parallel.
There are several things Day Of The Tenticle Download that some web browsers are not very good at. That's where the download managers enter the equation:
Pausing the downloading of large files.
Resuming broken or paused downloads (especially for Day Of The Tenticle Download very large Day Of The Tenticle Download files).
Downloading Day Of The Tenticle Download files on poor connections.
Downloading several files from a site automatically according Day Of The Tenticle Download to simple rules (file types, updated Day Of The Tenticle Download 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 Day Of The Tenticle Download dial-up users, they can automatically dial the internet service Day Of The Tenticle Download provider Day Of The Tenticle Download at night, when rates or tariffs are usually lower, download Day Of The Tenticle Download the specified files, and hang-up. They can record which links the user Day Of The Tenticle Download clicks on during the day, and queue these files for later download. For broadband users, download managers can help Day Of The Tenticle Download download very large files by resuming broken downloads, by Day Of The Tenticle Download limiting 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 Day Of The Tenticle Download also include automatically downloading Day Of The Tenticle Download whole sites and regularly updating them (see Mirroring).
Many download Day Of The Tenticle Download managers Day Of The Tenticle Download support Metalink, an Day Of The Tenticle Download XML file listing mirrors, checksums, and other information useful for downloading.
See below Day Of The Tenticle Download 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 Day Of The Tenticle Download managers, such as Go!Zilla, were among the first adware applications displaying a banner Day Of The Tenticle Download 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, Day Of The Tenticle Download Gnutella) and Day Of The Tenticle Download stream recorders (such as StreamBox VCR).
While download managers are designed to give users greater control over downloads, some Day Of The Tenticle Download downloaders are created to give that control to content Day Of The Tenticle Download distributors instead. Some software companies, for example Adobe [1], provide such downloaders Day Of The Tenticle Download for downloading software on their Day Of The Tenticle Download own site. Day Of The Tenticle Download Presumably this Day Of The Tenticle Download increases Day Of The Tenticle Download reliability and reduces tech support costs Day Of The Tenticle Download to them. A Day Of The Tenticle Download possible reason is increasing the control Day Of The Tenticle Download over redistribution Day Of The Tenticle Download of their software (even when the software is freeware).In computer technology and telecommunication, on-line Day Of The Tenticle Download and off-line are defined by Federal Standard Day Of The Tenticle Download 1037C. They are states or conditions of Day Of The Tenticle Download a "device or Day Of The Tenticle Download equipment" or of "a functional unit". Day Of The Tenticle Download To be considered on-line, a device must be at least Day Of The Tenticle Download one 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 demand by the system without human intervention"
"Connected to a system, and is in operation"
"Functional and ready for service"
while a device that is off-line Day Of The Tenticle Download is not (e.g. it has "its main power source disconnected Day Of The Tenticle Download or turned off", and is "off-power").
One example of a common use of these concepts is Day Of The Tenticle Download a Mail User Agent that can be instructed Day Of The Tenticle Download to Day Of The Tenticle Download be in either "on-line" or "off-line" states. Day Of The Tenticle Download One such MUA is Microsoft Outlook. When it is "on-line" it will attempt to connect to mail servers (to check for new Dvdfab Platinum Free Download mail at Day Of The Tenticle Download regular intervals, for example), and Day Of The Tenticle Download when it is "off-line" it will not attempt to make any such connections. The "on-line" or "off-line" state of the Day Of The Tenticle Download MUA does not Day Of The Tenticle Download necessarily reflect the connection status between the computer on which it is running and Internet. The user may have the Day Of The Tenticle Download computer itself on-line, connected to Internet via a Day Of The Tenticle Download cable modem or an ADSL connection, but may Day Of The Tenticle Download wish Day Of The Tenticle Download for Outlook to be off-line, so that it makes no attempt to send or to receive messages. Day Of The Tenticle Download Or the computer may be configured to employ a dial-up connection on demand (whenever an application Day Of The Tenticle Download such as Outlook attempts to make connection to a server), but the connection may be an Day Of The Tenticle Download expensive telephone call from the particular Day Of The Tenticle Download location in which the computer currently happens to Day Of The Tenticle Download be (such as a hotel room) and the user Day Of The Tenticle Download may not wish Outlook to trigger making that call Day Of The Tenticle Download every 5 or 10 minutes Day Of The Tenticle Download to check for mail.[1]
Another example of the use of these concepts is in the world of digital audio technology. A tape recorder, Day Of The Tenticle Download digital editor, or other device that is "on-line" is one whose clock is under the control of the Day Of The Tenticle Download clock of a "synchronization master" device. When the Day Of The Tenticle Download sync master commences playback, the "on-line" device automatically synchronizes itself to the master and commences playing from the Day Of The Tenticle Download same point in the recording. Whereas a device that is Day Of The Tenticle Download "off-line" uses no Day Of The Tenticle Download external clock reference and relies upon its own internal clock. Day Of The Tenticle Download When a large number Day Of The Tenticle Download of devices are connected to a sync master, it is often Day Of The Tenticle Download convenient, if one Day Of The Tenticle Download wants to Day Of The Tenticle 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 the playback point and wait for each other to be in synchronization.[2] (For further related discussion, Day Of The Tenticle Download see MIDI Day Of The Tenticle Download timecode, word sync, and recording Day Of The Tenticle Download system synchronization.)

A third example of Day Of The Tenticle Download a common use of these concepts is a web 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, Day Of The Tenticle Download users can perform offline browsing, where pages can be browsed using local Day Of The Tenticle Download copies of those pages that have previously been downloaded whilst in Day Of The Tenticle Download the "on-line" state. This Day Of The Tenticle Download can be useful when Download Ad-aware Pro the computer itself is also off-line, with Day Of The Tenticle Download connection to Internet expensive or impossible. The pages are either Family Guy Blue Harvest Download 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 Day Of The Tenticle Download certain web 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 Day Of The Tenticle Download by checking that the local copies are up-to-date whenever the Day Of The Tenticle Download browser is switched to the on-line state. One such web browser Day Of The Tenticle Download capable of being Day Of The Tenticle Download 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 Day Of The Tenticle Download marked page and, Day Of The Tenticle Download optionally, all of the pages that it links to. In Internet Explorer version 6, the level of direct Day Of The Tenticle Download and indirect links, the maximum amount of Day Of The Tenticle Download local disc space Day Of The Tenticle Download allowed to be Day Of The Tenticle Download consumed, and the schedule on which local copies are checked to see whether they are Day Of The Tenticle Download up-to-date, are configurable Day Of The Tenticle Download for each individual "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 Day Of The Tenticle Download saving, but not browsing or storing an entire site offline.[citation needed]
Similarly, off-line storage is 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 Day Of The Tenticle Download of "on-line" and "off-line" Day Of The Tenticle Download have been generalized from computing and telecommunication into the field of human interpersonal relationships. The distinction between what is considered "on-line" and what is considered "off-line" 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 Day Of The Tenticle Download between computer-mediated communication and face-to-face communication (e.g. face time), respectively. Norton Win Rescue Download "On-line" is virtuality, and "off-line" is reality (e.g. real life or meatspace). Day Of The Tenticle Download Slater states that this distinction Day Of The Tenticle Download is "obviously far too simple". To support his argument that the distinctions in Day Of The Tenticle Download relationships are Day Of The Tenticle Download more Day Of The Tenticle Download complex than a simple "on-line"/"off-line" dichotomy, he observes that Day Of The Tenticle Download 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, Day Of The Tenticle Download and Day Of The Tenticle Download that the blurring of the distinctions between the uses of various technologies (such as PDA and mobile Day Of The Tenticle Download telephone, Day Of The Tenticle 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 Day Of The Tenticle Download there are legal and regulatory pressures to Day Of The Tenticle Download reduce the distinction between Day Of The Tenticle Download "on-line" and "off-line", with a "general tendency to assimilate online to Day Of The Tenticle Download offline and erase the distinction", stressing, however, that this does not mean that on-line Day Of The Tenticle Download relationships are being reduced to pre-existing off-line Day Of The Tenticle Download relationships. He conjectures that greater legal status Day Of The Tenticle Download may be Day Of The Tenticle Download assigned to on-line relationships (pointing Day Of The Tenticle Download out that contractual relationships, such as business transactions, on-line are already seen as just Day Of The Tenticle Download as "real" as their off-line counterparts), although he states it to be hard to imagine courts awarding palimony Day Of The Tenticle 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 where "on-line" is seen as Day Of The Tenticle Download virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used to define and to explain "off-line" activities, Day Of The Tenticle Download rather than (as per Day Of The Tenticle Download the conventions of the desktop Day Of The Tenticle Download metaphor with Day Of The Tenticle Download its desktops, trash cans, folders, and Need For Speed Se Download so forth) the other way around. Several cartoons by The New Yorker have satirized this. One includes Saint Peter asking for 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 Day Of The Tenticle Download may be handled prior to purchase!". |
