Best Offer Diets To!
One Best Offer Diets To example of a common use of these concepts is a Mail User Agent that can be instructed to be in either "on-line" or "off-line" states. One such MUA is Microsoft Outlook. When it is "on-line" it will Best Offer Diets To attempt to connect to mail servers (to check for Best Offer Diets To new mail at regular intervals, for Best Offer Diets To example), and when it is Best Offer Diets To "off-line" it will not attempt to make any such connections. The "on-line" or Best Offer Diets To "off-line" state of the MUA does not necessarily reflect the connection status between the computer Best Offer Diets To on which it is running and Internet. The user may have Best Offer Diets To the computer itself on-line, connected to Internet via a Best Offer Diets Tocable modem or an ADSL connection, but Best Offer Diets To may wish for Outlook to be off-line, so that it makes no attempt to send or to receive messages. Or the computer mayBest Offer Diets Tobe Best Offer Diets To configured to employ a dial-up connection on demand (whenever an application such as Outlook attempts Best Offer Diets To to make connection to a server), but the Best Offer Diets To connection may be an Best Offer Diets To expensive Best Offer Diets To telephone call Best Offer Diets To from the particular Best Offer Diets To location in which the computer currently happens to be (such as Best Offer Diets To a hotel room) and Best Offer Diets To the user may not wish Outlook Best Offer Diets To to trigger making that call every 5 or 10 minutes to check for mail. Another example of Best Offer Diets To the use of these concepts is in the world of Best Offer Diets To digital audio technology. A tape recorder, digital editor, Best Offer Diets To 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 sync master commences playback, the "on-line" Best Offer Diets To device automatically synchronizes itself to the master and commences playing from Best Offer Diets To the same point in the recording. Whereas Best Offer Diets To a device that is "off-line" uses no external clock reference and relies upon its own internal Best Offer Diets To clock. When Best Offer Diets To a large number of devices are connected to a sync master, Best Offer Diets To it is often Best Offer Diets To convenient, if one wants to hear just the output of one single device, to take it off-line, because if Best Offer Diets To the device is played back on-line all synchronized devices have to locate the playback point and Best Offer Diets To wait for each other to be in synchronization.[2] (For further Best Offer Diets To related discussion, see MIDI timecode, word sync, and recording system synchronization.) A Best Offer Diets To third example of a common use of these concepts is a web browser that can be instructed to be in either Best Offer Diets To "on-line" or "off-line" states. Best Offer Diets To The browser only attempts to fetch Best Offer Diets To pages from servers whilst in Best Offer Diets To the "on-line" state. In the "off-line" state, users can perform offline browsing, Best Offer Diets To where pages can be browsed using local Best Offer Diets To copies of those pages that have previously been downloaded whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with Best Offer Diets To connection to Internet expensive or impossible. The pages are either downloaded implicitly into the web browser's own cache, as Best Offer Diets To a result of prior on-line browsing by the Best Offer Diets To user, or explicitly Best Offer Diets To by the browser being configured to Best Offer Diets To keep local copies of certain web pages, which it keeps Best Offer Diets To updated when the browser is in the on-line state, either by checking that the local Best Offer Diets To copies are up-to-date at regular intervals or by checking that the local copies are up-to-date whenever the browser is switched to the on-line Best Offer Diets To state. One such Best Offer Diets To web browser capable of being explicitly configured to download pages for offline browsing is Internet Explorer. When pages Best Offer Diets To are added to the "Favourites" list, they can Best Offer Diets To be marked for being made "available for offline browsing". Internet Best Offer Diets To Explorer will download to local copies both the marked page and, Best Offer Diets To optionally, all of the pages that it links to. In Internet Explorer version 6, the level of direct and indirect links, Best Offer Diets To the maximum amount of local disc Best Offer Diets To space allowed to be consumed, and Best Offer Diets To the schedule on which local copies are checked to see Best Offer Diets To whether they Best Offer Diets To 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 of human interpersonal relationships. The distinction between what is considered "on-line" and what is Best Offer Diets To considered "off-line" has become a subject of study in the fieldBest Offer Diets Toof sociology.[7] The distinction between "on-line" and "off-line" is Best Offer Diets To conventionally seen as the distinction Best Offer Diets To between computer-mediated communication and face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, Best Offer Diets To and "off-line" is reality (e.g. real life or meatspace). Slater states Best Offer Diets To 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 distinction between an "on-line" relationship, such as indulging in cybersex, and an "off-line" relationship, such as being pen-pals. He also Best Offer Diets To argues that even Best Offer Diets To the telephone can be regarded as an "on-line" experience in some circumstances, and that the blurring of the distinctions between Best Offer Diets To the uses of various technologies Best Offer Diets To (such as 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 Best Offer Diets To by the first generation of Internet research".[7] Slater asserts that there are legal and regulatory pressures to reduce the distinction between Best Offer Diets To "on-line" Best Offer Diets To and "off-line", with a "general tendency to assimilate online to offline and erase the distinction", stressing, however, that this does Best Offer Diets To 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 that contractual relationships, such as business transactions, on-line are already seen as just as "real" as their off-line counterparts), although Best Offer Diets To he states it to be hard to imagine courts awarding palimony to people who have had a purely on-line sexual relationship. He Best Offer Diets To also conjectures that an "on-line"/"off-line" distinction may be seen by people Best Offer Diets To as "rather quaint and not quite comprehensible" within 10 years The distinction where "on-line" Best Offer Diets To is seen as virtuality and "off-line" as reality is sometimes inverted, with Best Offer Diets To "on-line" concepts being used to define and Best Offer Diets To to Best Offer Diets To explain "off-line" activities, rather than (as per Best Offer Diets To the conventions of the desktop metaphor with its desktops, trash cans, folders, and so Best Offer Diets To 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 Best Offer Diets To store" where "All items are actual size!", where shoppers may "Take itBest Offer Diets Tohome as Best No Load Mutual Funds soon as you pay for it!", and where "Merchandise may be handled Best Offer Diets To prior to purchase!". |
