One example of a common use of these How To Clear Search History concepts is a Mail User Agent that can be instructed to be in either "on-line" or "off-line" Copernic Desktop Search states. One such Genealogy Search Engine MUA Academic Search Engine 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 "off-line" state of 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 itself on-line, connected to Internet via a Copernic Desktop Search cable modem or an ADSL Copernic Desktop Search connection, Copernic Desktop Search but may wish for Outlook to be off-line, so Copernic Desktop Search 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 a server), but the connection may Copernic Desktop Search be an Copernic Desktop Search expensive telephone call from the particular location Copernic Desktop Search in Copernic Desktop Search which Copernic Desktop Search the computer currently happens to be (such as a hotel room) and the user may not wish Outlook Copernic Desktop Search to trigger making that call Copernic Desktop Search 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 Copernic Desktop Search editor, or other Copernic Desktop 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 synchronizes itself to the Copernic Desktop Search master and commences playing from the same point in the recording. Whereas a device that is "off-line" Copernic Desktop Search uses no external clock reference Copernic Desktop Search and relies upon its own internal clock. When a large number of devices are Copernic Desktop Search connected to a sync master, it is often convenient, if one Copernic Desktop Search wants to hear just the output of one single device, to Copernic Desktop Search take it off-line, because if the Copernic Desktop Search device is played Copernic Desktop Search back on-line all Copernic Desktop Search synchronized devices have to locate the Copernic Desktop Search playback point and wait for each other to be Copernic Desktop Search 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 Copernic Desktop Search instructed to be in either "on-line" or "off-line" states. The browser only attempts to fetch pages from Copernic Desktop Search servers whilst in the "on-line" Copernic Desktop Search state. In the "off-line" state, users can perform offline browsing, where pages can be browsed using local copies of those pages that have previously been downloaded whilst in the "on-line" state. This can be useful when Copernic Desktop Search the computer itself is also Economical Engine Marketing Optimization Search off-line, with Copernic Desktop Search connection to Internet expensive or impossible. The pages are either downloaded implicitly into the web browser's own cache, as a result of prior on-line browsing Copernic Desktop Search by the user, or explicitly by the browser being configured Copernic Desktop Search to keep local copies of certain web pages, which it keeps updated when Copernic Desktop Search the browser Copernic Desktop Search is in Copernic Desktop Search 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 Copernic Desktop Search switched to the Copernic Desktop Search on-line state. One such web browser capable of being Copernic Desktop Search explicitly configured Copernic Desktop Search to download pages for offline browsing is Internet Explorer. When Copernic Desktop Search pages are Copernic Desktop Search added to the "Favourites" list, they can be marked for being made "available for offline browsing". Internet Explorer will download to local copies Copernic Desktop Search both the Copernic Desktop Search marked page and, optionally, all of the pages that it Copernic Desktop Search links to. In Internet Explorer version 6, the level of direct and indirect links, the maximum amount of local disc space Copernic Desktop Search allowed to be consumed, and the schedule on which local Copernic Desktop Search copies Copernic Desktop Search are checked to see whether they are Copernic Desktop Search up-to-date, are configurable for each

The Copernic Desktop Search ideas of "on-line" and "off-line" have been generalized from computing and telecommunication into the field Search Mubash of human Copernic Desktop Search interpersonal relationships. The distinction between what is considered "on-line" and Houston City Search what is considered "off-line" has become a subject of study in the field Copernic Desktop Search of sociology.[7]
The distinction between Copernic Desktop Search "on-line" and "off-line" is conventionally seen as the distinction between computer-mediated communication and Copernic Desktop Search face-to-face communication (e.g. face time), Copernic Desktop Search respectively. "On-line" is virtuality, and "off-line" is reality (e.g. real life or meatspace). Slater states that this distinction is "obviously far too simple". Copernic Desktop Search To support his argument that the distinctions in relationships Copernic Desktop Search are Bitttorrent Search more complex than Copernic Desktop Search a simple Copernic Desktop Search "on-line"/"off-line" dichotomy, he observes that some people draw no distinction Copernic Desktop Search between an "on-line" relationship, such as indulging in cybersex, Copernic Desktop Search and an "off-line" relationship, such as being Copernic Desktop Search pen-pals. He also argues Copernic Desktop Search that even the telephone can be regarded as Used Auto Parts Search an "on-line" experience in Copernicus Search some circumstances, and that the blurring of the distinctions between Copernic Desktop Search the uses of Copernic Desktop Search various technologies (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 Copernic Desktop Search sense that was employed by the first generation of Internet research".[7]
Slater asserts that Copernic Desktop Search there are legal Yahoo Job Search and regulatory pressures to reduce the Copernic Desktop Search distinction between "on-line" and "off-line", with Copernic Desktop Search a "general tendency to assimilate online to offline Copernic Desktop Search and erase the distinction", stressing, however, that Copernic Desktop Search this does Copernic Desktop Search not Copernic Desktop Search mean that on-line relationships are being reduced to pre-existing off-line relationships. Copernic Desktop Search He conjectures that greater legal status may be assigned to Copernic Desktop Search 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), Copernic Desktop Search although he states it to be hard to imagine courts awarding palimony to people who 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 Copernic Desktop Search quite comprehensible" within 10 years
The Copernic Desktop Search distinction where Copernic Desktop Search "on-line" is seen as virtuality and "off-line" as reality is Copernic Desktop Search sometimes inverted, with "on-line" concepts being used to define and to explain Copernic Desktop Search "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash cans, folders, and Copernic Desktop Search so forth) the other way around. Several cartoons by The New Yorker have satirized this. One includes Saint Peter Copernic Desktop Search asking Copernic Desktop Search for a user name and a password before admitting a man into Heaven. Another illustrates "the off-line store" where "All items Copernic Desktop Search are actual size!", where shoppers may "Take it home as soon as Copernic Desktop Search you pay for it!", and where "Merchandise may be handled prior to purchase!". |
