One example of Search Enginew a common use of these concepts is a Mail User Agent that can Search Ip Addresses be instructed to be in either Search Enginew "on-line" or "off-line" states. One such MUA is Microsoft Outlook. When it is "on-line" it will attempt to connect to mail Search Enginew servers (to Search Enginew check Search Enginew for new mail at Free Licence Plate Search regular intervals, for example), and when Search Enginew it is "off-line" Search Enginew it will not attempt to make any such Search Enginew connections. The "on-line" or "off-line" state of the MUA does not Search Enginew 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 Search Enginew via Search Enginew a cable modem or an ADSL connection, but may wish for Outlook to be off-line, so that Search Enginew it makes no attempt to send or to receive messages. Or the computer may Search Enginew be configured to employ a dial-up connection on demand (whenever an application such Search Enginew as Outlook attempts to make connection Search Enginew to a server), but the Search Enginew connection may be an expensive telephone call from the Search Enginew particular location in which the computer currently happens to be (such as a hotel room) and the user may Search Enginew not wish Outlook Search Enginew to trigger Search Enginew making that call every 5 Search Enginew or Search Enginew 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 whose clock is under the control of Search Enginew the clock of Search Enigins a International Search Consultants "synchronization master" device. When the sync master commences Search Enginew playback, the Search Enginew "on-line" device automatically synchronizes itself to the master and commences playing from the same point in the recording. Whereas a device that is "off-line" uses no external clock Search Enginew reference and relies upon its own internal clock. When a large number of devices are connected to a sync Search Enginew master, it is often convenient, if one wants to hear just the output of one Search Enginew single device, to take it off-line, because if the device is played Search Enginew back on-line all synchronized devices have to locate the Search Enginew playback point and wait for each other to be in synchronization.[2] (For further related Search Enginew discussion, Search Enginew see MIDI timecode, word sync, and recording system synchronization.)
A third example of a common use of these concepts is a web browser that Search Enginew can be Search Enginew instructed Search Enginew to be in either "on-line" or "off-line" states. The browser only attempts Search Enginew to fetch pages from servers whilst in the "on-line" state. In Search Enginew the "off-line" state, users can perform offline browsing, where pages can be browsed using local copies of those Search Enginew 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 Search Enginew to Internet expensive or impossible. The pages are either downloaded implicitly Search Enginew into the web browser's own cache, Search Enginew as a result of Search Enginew prior on-line browsing by the user, or Search Enginew 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 Search Enginew the local copies Search Enginew are up-to-date at regular Search Enginew intervals or by checking that the local copies are up-to-date whenever the browser Search Cam is switched to the on-line state. One such web browser capable of being explicitly configured to download pages for offline browsing is Search Enginew Internet Explorer. When pages Search Enginew are added to the Search Enginew "Favourites" list, they can be marked for being made "available for offline browsing". Internet Explorer will Job Search Engine Htm download to local copies both the marked page and, optionally, all of the pages that it links to. In Internet Explorer Search Enginew version Search Enginew 6, the Search Enginew level of direct and indirect links, the maximum amount of local disc space allowed to be consumed, and the schedule Search Enginew on which local Search Enginew copies are checked to see whether they are up-to-date, are Search Enginew configurable for each
The ideas of "on-line" and "off-line" have been generalized from computing and telecommunication into the field of Search Enginew human interpersonal relationships. The distinction between what is considered "on-line" and what is considered "off-line" has become a subject of study in the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as Friends Search the Search Enginew distinction between computer-mediated Search Enginew communication and face-to-face communication (e.g. Search Enginew face time), respectively. "On-line" is virtuality, and "off-line" is reality (e.g. real life or meatspace). Slater Search Enginew states that this distinction is "obviously far too simple". To Create Word Search Puzzles support his Search Enginew argument that the distinctions in relationships are more Search Enginew complex than a Search Enginew simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between an "on-line" relationship, such as Air Engine Search Travel indulging in Search Enginew cybersex, and Search Enginew Japan Search Engines an "off-line" relationship, such as being pen-pals. He also argues that even the telephone can Search Enginew be regarded as an "on-line" experience in some circumstances, and that the blurring Search Enginew of the distinctions between the uses of various technologies (such as PDA and mobile telephone, television and Internet, and telephone and voice-over-IP) Search Enginew has made it "impossible to use the term Search Enginew 'on-line' meaningfully in the sense that was employed by the first generation of Internet research".[7]
Slater asserts that there are legal and Search Enginew regulatory pressures to reduce the distinction between "on-line" and "off-line", with a "general tendency to assimilate online to offline and erase the distinction", stressing, however, that this does not mean that Free Find Anyone Address Search on-line relationships are Search Enginew being reduced to pre-existing off-line relationships. He conjectures that greater legal status Search Enginew may be assigned to on-line relationships (pointing out Search Enginew that contractual relationships, such as business transactions, on-line are already seen as just as "real" as Search Enginew their off-line counterparts), although he states it to be Search Enginew 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 Search Enginew may be seen by people as "rather Search Enginew quaint and not Search Enginew 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 Search Enginew being used to define and to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash Search Enginew cans, Search Enginew folders, and so forth) the other way around. Several cartoons by The New Yorker have Free Person Search Canada satirized this. One includes Saint Fast Internet Search Engine Peter asking for a user name and a password before admitting a Pill Imprint Search man into Heaven. Another illustrates "the off-line Search Enginew store" where "All items are actual Search Enginew size!", Buzz Credit Free Score Search Yahoo where shoppers may "Take it Search Enginew home as soon as you pay for it!", and where "Merchandise may be handled prior Search Enginew to purchase!". |
