One example of a common use of these concepts is a Mail User Agent that Rare Book Value Search can be instructed to be in either "on-line" or "off-line" Rare Book Value Search states. How Search Engine Works One such MUA is Microsoft Outlook. When it is "on-line" it will attempt to connect to mail servers (to check for new Rare Book Value Search mail at regular intervals, for example), and when it is "off-line" it will not attempt to make any Rare Book Value Search such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect Rare Book Value Search the connection status between the Amazon Book Search computer on which it is running and Rare Book Value Search Internet. The user may have the computer itself on-line, connected to Internet Rare Book Value Search via Rare Book Value Search a cable modem or an ADSL connection, but Rare Book Value Search may wish for Outlook to Rare Book Value Search be off-line, so that Rare Book Value Search it makes no attempt Rare Book Value Search to send or to receive messages. Or the computer may be configured to employ Rare Book Value Search a dial-up connection on demand (whenever an application such as Outlook attempts to make connection to a server), but the connection may be an expensive telephone call from the particular location in Rare Book Value Search which the computer currently happens to Rare Book Value Search be (such as a hotel room) and the user may not wish Outlook to trigger making Rare Book Value Search that call every 5 or 10 minutes to check for mail.
Another example of the use of these concepts is in the world Rare Book Value Search of digital audio technology. A tape recorder, digital editor, Historical Ship Search or other Ichp Search 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" device automatically Rare Book Value Search synchronizes Rare Book Value Search itself Rare Book Value Search to the master and commences Rare Book Value Search playing from the same point in the recording. Whereas a device that is "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 master, it is often Rare Book Value Search convenient, if one wants Rare Book Value Search to hear just the output of one Rare Book Value Search single device, to take it off-line, because if the Rare Book Value Search device Rare Book Value Search is played back Rare Book Value Search on-line Rare Book Value Search all synchronized devices have to locate the Free Database Search On Anyone playback point and wait Rare Book Value Search for each College And University Search other to be in synchronization.[2] (For further related discussion, see MIDI timecode, word sync, and recording system synchronization.)

A third example of Rare Book Value Search a common Rare Book Value Search use of these concepts is a web browser that Rare Book Value Search can be instructed to be in either "on-line" or "off-line" Rare Book Value Search states. The browser only Rare Book Value Search attempts to fetch pages from servers whilst in the "on-line" state. In the "off-line" state, users can perform Rare Book Value Search offline browsing, where Rare Book Value Search pages Rare Book Value Search can be browsed using local copies of those pages that have previously been downloaded whilst in Rare Book Value Search the "on-line" Rare Book Value Search state. This can be useful when 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 Rare Book Value Search on-line browsing by the user, or explicitly by the Rare Book Value Search browser Rare Book Value Search being configured to keep local copies of certain web pages, which it keeps Rare Book Value Search 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 Rare Book Value Search that the local copies are up-to-date whenever the browser is switched to the on-line Rare Book Value Search state. One Rare Book Value Search such web browser capable of being explicitly configured to download pages for offline browsing is Rare Book Value Search Internet Marketing Search Engine Optimisation Internet Explorer. When pages are added to the "Favourites" Rare Book Value Search list, they can be Rare Book Value Search 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 to. Mahoning County Property Search In Internet Explorer Rare Book Value Search version 6, Rare Book Value Search the level of Rare Book Value Search direct and indirect links, the maximum amount of local disc space allowed to be consumed, and the Rare Book Value Search 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 Rare Book Value Search from computing and telecommunication into the field of human Rare Book Value Search interpersonal relationships. The distinction between what is considered "on-line" and what is considered "off-line" has become a subject of study in Rare Book Value Search the field of Rare Book Value Search sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as the distinction between computer-mediated communication and Rare Book Value Search face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, Rare Book Value Search 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 Rare Book Value Search complex than a simple "on-line"/"off-line" dichotomy, he observes that some people draw no Rare Book Value Search distinction between Rare Book Value Search 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" experience in some circumstances, and that the blurring of the distinctions between the uses of various Rare Book Value Search technologies (such as PDA and mobile telephone, television and Internet, and telephone and voice-over-IP) has made it "impossible Oic Military Search For Fosset to use the term Rare Book Value Search 'on-line' Rare Book Value Search meaningfully in the sense that Rare Book Value Search was employed by the first generation of Internet research".[7]

Slater Web Search Results asserts that there are legal and regulatory pressures to Rare Book Value Search reduce the distinction between Rare Book Value Search "on-line" and "off-line", with a "general tendency to assimilate online to Turn Search Assistant Off offline and erase the distinction", stressing, however, that this does not mean that on-line relationships are being Rare Book Value Search reduced to Rare Book Value Search pre-existing off-line Rare Book Value Search relationships. He conjectures that greater Rare Book Value Search legal status Rare Book Value Search may be assigned to on-line Rare Book Value Search relationships Rare Book Value Search (pointing out that contractual relationships, such as business transactions, on-line are already Rare Book Value Search seen as just as "real" as their off-line counterparts), although he Rare Book Value Search states it to be hard to imagine Rare Book Value Search courts awarding palimony to people who Rare Book Value 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 virtuality and "off-line" as reality is sometimes inverted, Rare Book Value Search with "on-line" concepts being used to define and to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash Rare Book Value Search cans, folders, and so forth) the other way around. Several cartoons by The New Yorker Rare Book Value Search 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 store" where "All items are actual size!", where shoppers may Rare Book Value Search "Take it home as soon as you Rare Book Value Search pay for it!", and where "Merchandise may be handled prior Rare Book Value Search to purchase!". |
