One example of a common use of these concepts is a Mail User Agent that can be instructed Search Pravachol Lipitor to Search Pravachol Lipitor be in either "on-line" or "off-line" states. One such MUA is Microsoft Outlook. Search Pravachol Lipitor When it is Search Pravachol Lipitor "on-line" it will attempt Search Pravachol Lipitor to connect to mail servers (to check Search Pravachol Lipitor for new mail Search Pravachol Lipitor at regular intervals, for example), and when Search Pravachol Lipitor it is "off-line" it will not attempt to make any such connections. The "on-line" or "off-line" state of the Search Pravachol Lipitor MUA does not necessarily reflect the connection status between Search Pravachol Lipitor the computer on Search Pravachol Lipitor which it is running and Internet. The user Green Search may have the computer itself on-line, connected to Search Pravachol Lipitor Internet via a Search Pravachol Lipitor cable Search Pravachol Lipitor modem or an ADSL connection, but may wish for Outlook to be off-line, so that it makes no attempt to send or to receive messages. Or Search Pravachol Lipitor the computer may be configured to Search Pravachol Lipitor Privacy Google Desktop Search 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 Search Pravachol Lipitor happens to be (such as a hotel room) and the user may not wish Outlook to trigger Search Pravachol Lipitor making that call every 5 or 10 minutes to check for mail.
Another example of the use of these concepts is in the world of digital audio technology. A tape recorder, digital editor, or other device that is Search Pravachol Lipitor "on-line" is Search Pravachol Lipitor one whose clock is under the control of the clock of a "synchronization master" device. When the sync master commences playback, the "on-line" device automatically synchronizes itself to the Search Yahoo Comsearch P Diflucan master and commences playing from Address Search Canada the same point in the recording. Whereas Search Pravachol Lipitor a device that is "off-line" uses no external clock reference and relies upon Search Pravachol Lipitor its own internal clock. When Search Pravachol Lipitor a large number of devices Search Pravachol Lipitor are connected to a sync Search Pravachol Lipitor master, it is often convenient, if one wants to hear just the output of one single device, to take it off-line, because Search Pravachol Lipitor if the device Search Pravachol Lipitor is played back on-line all synchronized devices have to locate the playback Search Pravachol Lipitor point and wait for each other 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 Search Pravachol Lipitor web browser that can be instructed Search Pravachol Lipitor 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 Search Pravachol Lipitor be browsed using local copies of those pages that have previously been downloaded whilst in the "on-line" Search For A House To Rent state. This can Search Pravachol Lipitor be useful when the computer itself is also Search Pravachol Lipitor off-line, with connection Search Pravachol Lipitor to Internet expensive or impossible. The pages are Search For Cards Diver Dans Adventure 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 Search Pravachol Lipitor being configured to keep local Search Pravachol Lipitor copies of certain web pages, which it keeps updated when the browser is Search Pravachol Lipitor in Search Pravachol Lipitor the on-line state, Hp Printer Search either by checking that the Search Pravachol Lipitor local copies are up-to-date at regular intervals Search Engine Optimisation Solutions And Chester or by checking Search Pravachol Lipitor that the Search Pravachol Lipitor local copies are up-to-date whenever the browser is switched Search Pravachol Lipitor to the on-line state. One such Search Pravachol Lipitor web Search Pravachol Lipitor browser capable of being explicitly configured to Search Pravachol Lipitor 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. In Internet Explorer version 6, the level of direct and indirect Christian Search links, Search Pravachol Lipitor the maximum amount of local Search Pravachol Lipitor disc space Search Pravachol Lipitor allowed to be consumed, and the schedule on which local copies are checked to see whether they are up-to-date, are configurable for each

The ideas of "on-line" and "off-line" have been generalized from computing and telecommunication into the field Search Pravachol Lipitor 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" Search Pravachol Lipitor and "off-line" is conventionally seen as Search Pravachol Lipitor the distinction Free People Search Addresses between computer-mediated communication Search Pravachol Lipitor and face-to-face communication (e.g. Search Pravachol Lipitor face time), respectively. "On-line" Search Pravachol Lipitor is virtuality, and "off-line" is reality (e.g. 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 Search Pravachol Lipitor simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction Search Pravachol Lipitor between an Search Pravachol Lipitor "on-line" relationship, such Search Pravachol Lipitor as Search Pravachol Lipitor indulging in cybersex, and an "off-line" relationship, such as being pen-pals. He Search Pravachol Lipitor also argues that even the telephone can be regarded as an "on-line" experience in some circumstances, and that the blurring of the Search Pravachol Lipitor distinctions between the uses of various Search Pravachol Lipitor technologies (such as PDA and Search Pravachol Lipitor mobile telephone, television and Internet, Search Pravachol Lipitor and telephone and voice-over-IP) has made it "impossible to use the term 'on-line' meaningfully in the Search Pravachol Lipitor 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 "on-line" and "off-line", with a "general tendency to assimilate Search Pravachol Lipitor online to offline and erase the distinction", stressing, however, Search Pravachol Lipitor that this Search Pravachol Lipitor does not mean that on-line Search Pravachol Lipitor 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 that contractual relationships, such as Search Pravachol Lipitor business transactions, on-line are already seen Search Pravachol Lipitor as just as "real" as their off-line Search Pravachol Lipitor counterparts), although he states it to be hard to imagine courts awarding palimony 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 Search Pravachol Lipitor as "rather quaint and not quite comprehensible" within 10 years

The distinction where "on-line" is seen Search Pravachol Lipitor as Search Pravachol Lipitor virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used to Search Pravachol Lipitor define and to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash cans, folders, and so Search Pravachol Lipitor forth) Search Pravachol Lipitor the other way around. Several cartoons by The New Search Pravachol Lipitor Yorker have Search Pravachol Lipitor satirized this. One includes Saint Peter asking for a user name and Search Pravachol Lipitor a password before admitting a man into Search Pravachol Lipitor Heaven. Another illustrates "the off-line store" where Search Pravachol Lipitor "All items are Search Pravachol Lipitor actual size!", where shoppers may "Take it home as soon as you pay for it!", and where Search Pravachol Lipitor "Merchandise may be handled prior to purchase!". |
