One example of a common use of these concepts is a Mail User Copernicus Search Agent that can be instructed Copernicus Search to be in either "on-line" or "off-line" states. One such MUA is Microsoft Outlook. When it is "on-line" it will attempt Copernicus Search to connect to mail servers (to check for new mail at regular intervals, for example), Copernicus Search and Copernicus Search when it is "off-line" it will How To Clear Search History not attempt to make any such connections. The "on-line" or "off-line" state of the Copernicus Search MUA does Copernicus Search not necessarily reflect the connection status between 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 ADSL connection, but may wish for Copernicus Search Outlook to be Copernicus Search off-line, so that it makes no Copernicus Search attempt to send or to receive messages. Or the computer may Copernicus Search be configured to employ a dial-up connection on demand (whenever an application such Copernicus Search as Outlook attempts to Copernicus Search 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) Copernicus Search and the user may not wish Outlook Copernicus Search to trigger Copernicus Search making that call every 5 or 10 minutes to check for mail.
Another example of Copernicus Search the use of these concepts is in the world of digital audio technology. A tape recorder, digital editor, Copernicus Search or other Copernicus Search device that is "on-line" is one whose clock is under the control of the clock of a "synchronization Copernicus Search master" device. When the sync master commences playback, the Copernicus Search "on-line" Copernicus Search device automatically synchronizes Copernicus Search itself to the master and commences playing from the same point in the recording. Whereas a device Copernicus Search 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 Copernicus Search is often convenient, if one wants to Copernicus Search hear just the output Copernicus Search 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, see MIDI timecode, word sync, and recording Copernicus Search system synchronization.)
A third example of Copernicus Search a common use of these concepts is Genealogy Search Engine a Copernicus Search web browser that Copernicus Search can be instructed to be in either "on-line" or "off-line" states. Copernicus Search The browser Copernicus Search 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 Copernicus Search copies of those Copernicus Search pages that have previously been Copernicus Search downloaded whilst in the "on-line" state. This can be useful when Copernicus Search the computer itself is also off-line, with connection Copernicus Search to 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, or explicitly by the browser being configured Academic Search Engine to keep local copies of certain web pages, which Copernicus Search it keeps updated when the browser is Copernicus Search in the on-line state, either by checking that the local copies are up-to-date at Copernicus Search regular Copernicus Search intervals Copernicus Search or by checking that the local copies are up-to-date whenever the browser is switched to the on-line state. One such Copernicus Search web browser capable Copernicus Search of being explicitly configured to download pages for offline browsing is Copernicus Search Internet Explorer. When pages are added to the "Favourites" Economical Engine Marketing Optimization Search list, Copernicus Search they can be marked for being made "available for offline browsing". Internet Explorer will download to local copies both the Copernicus Search marked page and, optionally, all of the pages that it links to. In Copernicus Search Internet Explorer Search Mubash version 6, the level of direct and indirect links, the maximum amount of local disc space allowed to be consumed, and the Copernicus Search schedule on which Copernicus Search local copies are checked to see whether Copernicus Search they are up-to-date, are Copernicus Search configurable for each
The ideas of "on-line" and "off-line" have been generalized from computing and telecommunication into the field of human interpersonal Copernicus Search relationships. The distinction between what is considered "on-line" and what is considered "off-line" Copernicus Search has become a subject of study in the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as Copernicus Search the distinction between computer-mediated communication and face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, and Copernicus Search "off-line" is reality (e.g. Copernicus Search real life or meatspace). Slater states that this distinction is "obviously far too simple". To support his argument that the distinctions in relationships are more complex than a simple "on-line"/"off-line" dichotomy, he observes that some people Copernicus Search 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 Copernicus Search in some circumstances, and that the blurring Copernicus Search of the distinctions between the uses of various technologies Houston City Search (such as PDA and Copernicus Search 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 Copernicus Search was employed Copernicus Search by the first generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures to reduce the distinction between "on-line" and "off-line", Copernicus Search with a "general tendency to Copernicus Search 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 Copernicus Search off-line relationships. He Copernicus Search conjectures Copernicus Search that greater legal status may be assigned to on-line relationships (pointing out that contractual Copernicus Search relationships, such as business transactions, Copernicus Search on-line are already seen as just as "real" as their Copernicus Search off-line counterparts), although he states it to be Bitttorrent Search hard to imagine courts awarding palimony Copernicus Search 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 Copernicus Search as "rather quaint and not quite comprehensible" within 10 years
The Copernicus Search distinction where "on-line" is seen as virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used to Copernicus Search define and to explain Copernicus Search "off-line" activities, rather than (as per the conventions of the desktop Copernicus Search metaphor with its desktops, trash cans, Copernicus Search folders, and so forth) the other way around. Several cartoons by The Copernicus Search New Yorker have satirized this. One includes Saint Peter asking for a user name Copernicus Search and a password before Copernicus Search admitting a man Copernicus Search into Heaven. Another illustrates "the off-line store" where "All items are actual size!", where shoppers Copernicus Search may "Take it home Copernicus Search as soon Used Auto Parts Search as you pay for it!", and where "Merchandise may be handled prior to purchase!". |
