One example Search Engine Management of a common use of these concepts is a Mail User Agent that can be instructed to be in either "on-line" Search Engine Management or Search Engine Management "off-line" states. One such MUA Search Engine Management 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 Search Engine Management it is "off-line" it will not Search Engine Management attempt to Search Engine Management make any such connections. The "on-line" or "off-line" state of the MUA does not necessarily Search Engine Optimisation Expert reflect the connection status between the computer on which it is running and Internet. The user may have Search Engine Management the computer itself on-line, Search Engine Management connected to Internet via a Search Engine Management cable modem or an ADSL connection, but may wish for Outlook to be off-line, so that it makes no attempt to Search Engine Management send or to receive messages. Or the computer may be configured to employ a dial-up connection Search Engine Management on demand Search Engine Management (whenever an application such Search Engine Management as Search Engine Management Outlook attempts to make connection Search Engine Management 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) and the user may not wish Outlook to trigger making that Search Engine Management call every 5 or 10 minutes to check for mail.
Another example Search Engine Management of the use of these concepts is in Search Engine Management Types Of Search Engines the world of digital audio technology. A tape recorder, digital editor, or other device Search Engine Management that is "on-line" is one whose clock is under the control Search Engine Management of the clock of a "synchronization master" device. When the sync master commences playback, the "on-line" device automatically synchronizes itself to the master and commences playing from the same point in the recording. Whereas a device that is Search Engine Management "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 Search Engine Management master, it is often convenient, if one wants to hear just Search Engine Management the output 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 Search Engine Management for each other to be in synchronization.[2] (For further related discussion, see MIDI timecode, Search Engine Management word Search Engine Management sync, Search Engine Management and recording system synchronization.)

A third example of a Search Engine Management 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 fetch pages from servers whilst in Search Engine Management the "on-line" state. In the "off-line" state, users can perform offline browsing, where pages can be browsed using local copies of those Search Engine Management pages that Search Engine Management have previously been downloaded whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with connection to Internet Search Engine Management expensive or impossible. The pages are either downloaded implicitly into the Search Engine Management web browser's own cache, as a result Search Engine Management of prior on-line Search Engine Management browsing by the user, or explicitly by the browser being configured to Search Engine Management keep local copies of Search Engine Management 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 copies are up-to-date whenever the browser is switched to the on-line state. One such web browser capable of being explicitly configured to download pages for offline browsing is Internet Search Engine Management Explorer. When pages are added to the "Favourites" list, they can be marked for being made "available for offline Search Engine Management browsing". Internet Explorer will download to local copies both the marked page and, Search Engine Management optionally, all of the pages that it links to. In Search Engine Management Internet Explorer version 6, the level Search Engine Management of direct and indirect links, the Search Engine Management maximum amount of local disc space allowed to be consumed, and the schedule on which local copies are checked to Search Engine Management see whether they are up-to-date, are configurable Search Engine Management Search Engine Optimisation Chester for Search Engine Management each

The ideas of "on-line" and Search Engine Management "off-line" have been generalized from computing and telecommunication into the field of human interpersonal relationships. The distinction between what is Search Engine Management considered "on-line" and what is considered "off-line" has become a subject of Search Engine Management study in the field of Search Engine Management sociology.[7]
The distinction between "on-line" and "off-line" is Search Engine Management 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 reality (e.g. real life or meatspace). Slater states Search Engine Management that this distinction is "obviously far too simple". To support his argument Search Engine Management that the distinctions in relationships are more complex than Search Engine Management a simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between an Search Engine Management "on-line" Search Engine Management relationship, such Search Engine Management as indulging in cybersex, and an "off-line" relationship, Search Engine Management such as being pen-pals. He also argues that even the Search Engine Management telephone can be regarded as an "on-line" experience in some circumstances, and that the blurring of the distinctions between the uses of various technologies (such as Search Engine Management PDA and mobile telephone, television and Internet, and Search Engine Management telephone and voice-over-IP) has made it "impossible to use the term Search Engine Management 'on-line' meaningfully in Denton County Criminal Search the sense that was Search Engine Management employed by the first generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures to reduce the Search Engine Management distinction between "on-line" and "off-line", with a Search Engine Management Increase Search Engine Ranking "general tendency to assimilate online to offline and erase the distinction", stressing, however, that this does Search Engine Management not mean that on-line relationships are being reduced to pre-existing off-line relationships. He conjectures Search Engine Management that greater legal status may be assigned to on-line relationships (pointing out that contractual relationships, such Search Engine Management as business transactions, on-line are already seen as just as "real" as their Search Engine Management off-line counterparts), although he states it Search Engine Management to be hard to imagine courts awarding palimony to people who Search Engine Management have had a purely on-line sexual Search Warrant relationship. Search Engine Management He also conjectures that Search Engine Management an "on-line"/"off-line" distinction may be seen by people as "rather quaint and not quite Dallas Search Engine Marketing comprehensible" within 10 years

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