One Used Auto Parts Search example Used Auto Parts Search of a common use of these Used Auto Parts Search concepts is a Mail User Agent that can be instructed to be in either "on-line" or "off-line" states. One such MUA Used Auto Parts Search is Used Auto Parts Search Microsoft Outlook. Used Auto Parts Search When Used Auto Parts Search it is "on-line" it Used Auto Parts Search 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 "off-line" state of Used Auto Parts Search the MUA does not necessarily reflect the connection status between the computer on which it is running and Internet. The user may have the computer Used Auto Parts Search itself on-line, connected to How To Clear Search History Internet via a cable modem or an ADSL connection, but may wish for Outlook to Genealogy Search Engine be off-line, so that it makes no attempt to send or to receive messages. Or the computer may be configured to employ a dial-up connection on demand (whenever an application such as Outlook attempts to make connection to Used Auto Parts Search a server), but the connection may Used Auto Parts Search be an expensive telephone call from the particular location in which the computer currently happens to be (such as a hotel room) Used Auto Parts Search and the user Used Auto Parts Search may not wish Outlook to trigger making that call every 5 or 10 Used Auto Parts Search 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 whose clock is under the control of the clock of Used Auto Parts Search a "synchronization master" device. When the sync master commences playback, the "on-line" device automatically synchronizes itself Used Auto Parts Search to the master Academic Search Engine and commences playing from the same point in Used Auto Parts Search the recording. Whereas a device that is "off-line" uses no Used Auto Parts Search external clock reference and relies upon its own internal clock. When a large number Used Auto Parts Search of devices are connected to a sync master, it is often convenient, if one Used Auto Parts Search wants to hear Used Auto Parts Search just Used Auto Parts Search the output of one single device, to take it off-line, because if the device is Used Auto Parts Search played back on-line all synchronized Used Auto Parts Search devices have to locate the playback point and wait for each Used Auto Parts Search 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 web browser that can be instructed to be in either Used Auto Parts Search "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" Used Auto Parts Search state, users can perform Used Auto Parts Search offline browsing, where Used Auto Parts Search pages can be Used Auto Parts Search browsed using local 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 connection to Internet expensive or impossible. The pages are either Used Auto Parts Search downloaded implicitly into the web browser's own cache, as a Used Auto Parts Search result Used Auto Parts Search of prior on-line browsing Economical Engine Marketing Optimization Search by the user, Used Auto Parts Search or Used Auto Parts Search explicitly Used Auto Parts Search by the browser being configured to keep local copies of certain web pages, which it Used Auto Parts Search keeps updated when the browser is in the on-line state, Used Auto Parts Search 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 Used Auto Parts Search on-line state. One such web browser capable of being Used Auto Parts Search explicitly configured to download pages for offline browsing is Internet Used Auto Parts Search Explorer. When Used Auto Parts Search pages are added to the Search Mubash "Favourites" list, they can be marked for being made "available for Used Auto Parts Search offline browsing". Used Auto Parts Search 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 links, the maximum amount of local disc space allowed to Houston City Search be consumed, and the Used Auto Parts Search schedule on which local copies are checked Used Auto Parts Search to see whether they are up-to-date, are configurable for each

The ideas Used Auto Parts Search of "on-line" and "off-line" have been generalized from Used Auto Parts Search computing and telecommunication into the field of human interpersonal relationships. The distinction between what is considered "on-line" and what is considered Used Auto Parts Search "off-line" Used Auto Parts Search has become a subject of study in the field of sociology.[7]
The distinction between Used Auto Parts Search "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 reality (e.g. real life or meatspace). Slater states that this distinction is "obviously far Used Auto Parts Search 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" Used Auto Parts Search relationship, such as indulging in cybersex, and an "off-line" relationship, such as being Used Auto Parts Search pen-pals. He also argues that even the telephone can be regarded as an "on-line" experience in some circumstances, and that the Used Auto Parts Search blurring of the distinctions Used Auto Parts Search between the uses of various technologies (such as PDA Used Auto Parts Search Bitttorrent Search and mobile telephone, television and Internet, and Used Auto Parts Search telephone and voice-over-IP) has made it "impossible to use the term 'on-line' meaningfully in the sense that Used Auto Parts Search was employed by the first generation of Internet research".[7]
Slater asserts that there are legal and regulatory Used Auto Parts Search pressures to Used Auto Parts Search reduce the Used Auto Parts Search distinction between "on-line" and Used Auto Parts Search "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 Used Auto Parts Search relationships are being reduced to pre-existing off-line relationships. He conjectures Used Auto Parts Search that greater legal Used Auto Parts Search 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 Used Auto Parts Search he states it to Used Auto Parts Search be hard to imagine courts awarding palimony to people who Used Auto Parts Search have had a purely 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" is seen as Used Auto Parts Search virtuality and Used Auto Parts Search "off-line" as reality is sometimes inverted, with "on-line" concepts being used to Used Auto Parts Search define Used Auto Parts Search and to explain "off-line" Used Auto Parts Search activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash cans, folders, and Used Auto Parts Search so forth) Used Auto Parts Search the other Used Auto Parts Search way around. Several cartoons by The New Yorker Used Auto Parts Search have satirized this. One Used Auto Parts Search includes Saint Peter asking for a user name and a password before admitting a man into Heaven. Another illustrates "the Used Auto Parts Search off-line store" where "All items are Used Auto Parts Search actual size!", where shoppers may "Take it Used Auto Parts Search home as soon as Used Auto Parts Search you pay for it!", and where "Merchandise may be handled prior Used Auto Parts Search to purchase!". |
