One example of Search Engine Ranking Optimization a Search Engine Ranking Optimization common use of these concepts is a Mail User Agent that can be Search Engine Ranking Optimization instructed to be in either "on-line" or "off-line" states. Search Engine Ranking Optimization One such MUA is Microsoft Outlook. When it is "on-line" it will attempt to connect to mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" it will not attempt to make any such connections. The "on-line" or Search Engine Ranking Optimization "off-line" state of the Search Engine Ranking Optimization MUA does not Search Engine Ranking Optimization necessarily reflect the connection status between the computer on which it is running and Internet. The user may have Search Engine Ranking Optimization the computer Search Engine Ranking Optimization itself on-line, connected Search Engine Ranking Optimization to Internet via a cable modem or an ADSL connection, but may wish Search Engine Ranking Optimization for Outlook to be off-line, so that it makes Search Engine Ranking Optimization no attempt to send or to receive Search Engine Ranking Optimization messages. Or Search Engine Ranking Optimization the computer may be configured to employ a dial-up connection on demand (whenever an application Search Engine Ranking Optimization such as Search Engine Ranking Optimization Outlook attempts Search Engine Ranking Optimization to make connection to a Search Engine Ranking Optimization Social Security Number Search 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) and the user may not wish Outlook Search Engine Ranking Optimization 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. A tape recorder, digital editor, or other device that is "on-line" is one Search Engine Ranking Optimization whose Search Engine Ranking Optimization clock is under the Improve Search Engine Ranks control of the clock of a "synchronization master" device. When the sync master commences playback, the "on-line" device automatically synchronizes Search Engine Ranking Optimization itself to the master and commences playing Google Web Search from the same point in the recording. Search Engine Ranking Optimization Whereas a device that is "off-line" uses no external clock reference and relies upon Search Engine Ranking Optimization its own Search Engine Ranking Optimization internal Search Engine Ranking Optimization clock. When a large number of devices are Search Engine Ranking Optimization connected to a sync master, it is often Search Engine Ranking Optimization convenient, if Search Engine Ranking Optimization one wants to hear just the output of one single device, to take it off-line, Search Engine Ranking Optimization because if the Crack Search Engine 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 system synchronization.)

A third example of a common use of Search Engine Ranking Optimization these concepts is a web browser that can be instructed Search Engine Ranking Optimization to be in either "on-line" or Search Engine Ranking Optimization "off-line" Search Engine Ranking Optimization states. The browser only attempts to fetch pages from servers whilst in the Search Engine Ranking Optimization "on-line" state. Search Engine Ranking Optimization Search Engine Listing In the Search Engine Ranking Optimization "off-line" state, users can perform offline browsing, where pages can be Search Engine Ranking Optimization browsed using local copies of those pages that have previously been downloaded Search Engine Registration whilst in the "on-line" state. This can be useful when the computer Search Engine Ranking Optimization itself Search Engine Ranking Optimization is also off-line, with connection to Internet expensive or impossible. The pages are either Search Engine Ranking Optimization downloaded implicitly into the web browser's own Search Engine Ranking Optimization cache, as a result of prior on-line browsing by the user, or explicitly by the browser being configured to keep local copies of 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 by checking that the local Search Engine Ranking Optimization copies are up-to-date whenever the Search Engine Ranking Optimization browser is switched Search Engine Ranking Optimization to the on-line state. One such web browser capable of being explicitly configured to download pages for offline browsing is Internet Explorer. When pages are added to Search Engine Ranking Optimization the Search Ck "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 Search Engine Ranking Optimization to. In Internet Explorer version 6, the level of direct and indirect links, Search Engine Ranking Optimization the maximum amount Search Engine Ranking Optimization of local disc space 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 Search Engine Ranking Optimization field of human interpersonal relationships. The distinction Search Engine Ranking Optimization between what is considered "on-line" Search Engine Ranking Optimization and what is considered "off-line" has become a Search Engine Ranking Optimization subject of study in Search Engine Ranking Optimization the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as the distinction between computer-mediated communication and face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, and "off-line" is Search Engine Ranking Optimization reality (e.g. real life or meatspace). Slater states that this distinction is "obviously far too Search Engine Ranking Optimization simple". To support his argument that the distinctions in relationships are more Search Engine Ranking Optimization complex than a simple "on-line"/"off-line" Search Engine Ranking Optimization dichotomy, Search Engine Ranking Optimization 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 argues that even the telephone can be regarded as an "on-line" Search Engine Ranking Optimization experience in some circumstances, and that the blurring of the distinctions between the uses of Search Engine Ranking Optimization various technologies (such as PDA and mobile Search Engine Ranking Optimization telephone, television and Internet, and telephone and voice-over-IP) has Search Engine Ranking Optimization made Search Engine Ranking Optimization 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 there are legal and regulatory pressures Search Engiens to reduce the distinction between "on-line" Search Engine Ranking Optimization and "off-line", with a "general tendency to assimilate online to offline and erase the distinction", stressing, however, that this does not Search Engine Ranking Optimization mean that on-line relationships are being reduced to pre-existing off-line relationships. He conjectures that greater legal status may be assigned to Search Engine Ranking Optimization on-line relationships (pointing out that contractual Search Engine Ranking Optimization relationships, such as business transactions, on-line Search Engine Ranking Optimization are already seen as just Search Engine Ranking Optimization as Search Engine Ranking Optimization "real" as Search Engine Ranking Optimization their off-line counterparts), although Search Engine Ranking Optimization he states Search Engine Ranking Optimization it to be hard to imagine courts awarding palimony to people who have E Mail Search had Search Engine Ranking Optimization a purely on-line sexual relationship. He also conjectures that an "on-line"/"off-line" Search Engine Ranking Optimization distinction may be seen by Search Engine Ranking Optimization people as "rather quaint and not quite comprehensible" within 10 years

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