One Best Free Pravachol example Best Free Pravachol of Best Free Pravachol a common use Best Free Pravachol of these Best Free Pravachol concepts is a Mail User Agent that can Best Free Pravachol be instructed Best Free Pravachol to be in either "on-line" Best Free Pravachol or "off-line" states. One such MUA is Microsoft Best Free Pravachol Outlook. When it Best Free Pravachol is "on-line" it Best Free Pravachol will attempt to connect to mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" Best Free Pravachol it will not Best Free Pravachol attempt to make Best Free Pravachol any such connections. The "on-line" or "off-line" state of the MUA Best Free Pravachol does not necessarily reflect the connection status between the computer on which it is running and Internet. The user Best Free Pravachol may have the computer itself on-line, connected to Internet via a cable 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 Best Free Pravachol messages. Or the computer may be configured to employ a dial-up connection on demand (whenever an application such as Outlook attempts Best Free Pravachol to Absolute Best Ever Beer Songs make connection to a server), but the connection may be an expensive telephone call from the particular location Best Free Pravachol in which Best Free Pravachol the computer currently happens Best Free Pravachol to be (such as a hotel room) and the user may not wish Outlook to trigger 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. Best Free Pravachol A tape recorder, digital editor, or other device that is Best Free Pravachol "on-line" is one whose Best Free Pravachol clock is under the control of the Best Free Pravachol clock of a "synchronization master" device. When the sync master commences playback, the "on-line" Best Free Pravachol device automatically synchronizes itself to the master and commences Best Free Pravachol playing from the same point in the recording. Whereas a device that is "off-line" Best Free Pravachol uses no external Best Free Pravachol clock reference Best Free Pravachol and relies upon Best Free Pravachol its own internal clock. When a large number of devices are connected to a sync master, it is often convenient, if one wants to hear just the output of one single device, to take it off-line, because if the device is played back Best Free Pravachol on-line Best Free Pravachol all synchronized devices have to locate the playback Best Free Pravachol point and wait for each other to be in synchronization.[2] (For further related discussion, see MIDI timecode, word sync, and recording Best Free Pravachol system synchronization.)

A third example of 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 Best Free Pravachol 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 Best Free Pravachol copies of those pages that have previously been downloaded whilst Best Free Pravachol in the "on-line" state. This can be useful when Best Free Pravachol the computer itself is also off-line, with connection 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 to keep local copies of Best High Interest Sav certain web pages, Best Free Pravachol which it keeps updated when the browser is in the on-line state, either by Best Free Pravachol checking that Best Free Pravachol the local copies are Best Free Pravachol up-to-date at regular intervals Best Free Pravachol or by Best Free Pravachol checking that the local copies are up-to-date whenever Best Free Pravachol the browser is switched to the on-line state. Best Free Pravachol One such web Best Free Pravachol browser capable of being Best Free Pravachol 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 Best Free Pravachol to local copies both the Best Free Pravachol marked page and, optionally, all of the pages that it links to. In Internet Explorer version Best Free Pravachol 6, the level of direct and indirect links, the maximum amount Best Free Pravachol of Best Free Pravachol local disc space Best Free Pravachol allowed to be Best Free Pravachol consumed, and the schedule on which local copies are checked to see whether they are up-to-date, are configurable Best Honda Service On Li for each

The ideas of "on-line" and "off-line" have been generalized from computing and telecommunication into the field of human interpersonal relationships. The distinction between Best Mp3 Download Sites what is considered "on-line" Best Free Pravachol and what is considered "off-line" has become a subject of study in the Best Free Pravachol field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as the distinction between computer-mediated communication Best Free Pravachol and face-to-face communication (e.g. face time), respectively. Best Free Pravachol "On-line" 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 simple "on-line"/"off-line" dichotomy, he observes that some people draw no Best Free Pravachol distinction between an "on-line" relationship, such as indulging in cybersex, and an "off-line" relationship, Best Free Pravachol such as Best Free Pravachol being pen-pals. He also argues that even the telephone Best Free Pravachol can be regarded as an "on-line" experience in Best Free Pravachol some circumstances, and that the blurring of the distinctions between the uses of Best Free Pravachol various technologies (such as PDA and Best Free Pravachol 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 Best Free Pravachol employed by the Best Free Pravachol first generation of Internet research".[7]
Slater asserts that there are legal and Best Free Pravachol regulatory pressures to reduce the Best Free Pravachol distinction between "on-line" and "off-line", 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 Best Free Pravachol being reduced to pre-existing off-line relationships. Best Free Pravachol He conjectures that greater legal status may Best Free Pravachol be assigned to on-line relationships (pointing out that contractual relationships, such as business transactions, on-line are already seen as just as "real" as their off-line counterparts), although he states it to be hard to imagine courts awarding palimony Best Free Pravachol to people who have had a purely Best Free Pravachol 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

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