One example of a common use of these concepts is London Search Engine Promotion a Mail User Agent that London Search Engine Promotion can be instructed to be in either "on-line" London Search Engine Promotion or "off-line" states. One such MUA is Microsoft Outlook. When it is "on-line" London Search Engine Promotion it will attempt to connect to mail servers (to check for new mail at regular intervals, for London Search Engine Promotion example), and when it is "off-line" it will not attempt to make any such connections. The Search Engine Positioning Ppc Management "on-line" or "off-line" state of the London Search Engine Promotion MUA does not necessarily reflect the London Search Engine Promotion 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 cable modem or an London Search Engine Promotion ADSL London Search Engine Promotion connection, but may wish for Outlook to be off-line, London Search Engine Promotion so that it makes London Search Engine Promotion no attempt London Search Engine Promotion to send or to receive messages. Or London Search Engine Promotion 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 be an expensive London Search Engine Promotion telephone call from the particular location in which the London Search Engine Promotion computer currently happens to be (such as a hotel room) and the user may not wish Outlook to trigger making that call every 5 or 10 minutes to check for mail.
Another example of London Search Engine Promotion the use of these concepts is London Search Engine Promotion 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 London Search Engine Promotion the clock of a "synchronization master" London Search Engine Promotion 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. London Search Engine Promotion Whereas London Search Engine Promotion a device that is "off-line" uses no external clock reference London Search Engine Promotion and relies upon its own internal clock. When a large number of devices London Search Engine Promotion are connected to a sync master, it is often convenient, if one wants to hear just the output of one single device, to take it off-line, because if the Search For A Book Free device London Search Engine Promotion is played back on-line all synchronized devices have London Search Engine Promotion to locate the playback point and wait for each other to be in synchronization.[2] London Search Engine Promotion (For further related discussion, see MIDI timecode, word sync, and recording system synchronization.)

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

The ideas of "on-line" and "off-line" have been generalized from computing and telecommunication into London Search Engine Promotion the field of human interpersonal relationships. The distinction between what is considered London Search Engine Promotion "on-line" and what is considered "off-line" has become London Search Engine Promotion a subject of Search City County study London Search Engine Promotion in the field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally London Search Engine Promotion seen as the distinction between computer-mediated London Search Engine Promotion communication and face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, London Search Engine Promotion and London Search Engine Promotion "off-line" is reality (e.g. real life or meatspace). Slater states that this distinction is "obviously far too simple". To support his London Search Engine Promotion argument that the London Search Engine Promotion distinctions in relationships are more London Search Engine Promotion complex than a simple "on-line"/"off-line" dichotomy, he observes that some people draw London Search Engine Promotion no distinction between 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 London Search Engine Promotion an "on-line" experience in some circumstances, and that the blurring of the distinctions between the uses London Search Engine Promotion of 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 sense that London Search Engine Promotion was employed by London Search Engine Promotion the first generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures to reduce the distinction between "on-line" and "off-line", with a "general tendency to assimilate online to London Search Engine Promotion offline and erase the distinction", stressing, London Search Engine Promotion however, that this does not mean London Search Engine Promotion that on-line relationships are London Search Engine Promotion being reduced to pre-existing off-line relationships. He conjectures that greater legal status London Search Engine Promotion may London Search Engine Promotion be assigned to on-line relationships (pointing out that contractual relationships, such London Search Engine Promotion as business transactions, London Search Engine Promotion on-line are already seen as just as "real" as their off-line counterparts), London Search Engine Promotion although he states it to be hard to imagine courts awarding palimony to London Search Engine Promotion people who have London Search Engine Promotion had a purely on-line sexual relationship. London Search Engine Promotion He also conjectures that an "on-line"/"off-line" distinction may be seen by London Search Engine Promotion people as "rather Search For Restaurant- De quaint and not quite comprehensible" within 10 years

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