One example of a common use of these concepts is a Mail User Agent that can be instructed to be in either "on-line" or "off-line" states. One such MUA is Microsoft Outlook. When it is "on-line" it will attempt to Buy New Car Online connect to mail Buy Suboxone servers (to check for new mail at regular Buy New Car Online intervals, for example), and when it is "off-line" it will not attempt to make any such Buy New Car Online connections. The "on-line" or "off-line" state of the MUA Buy New Car Online does not necessarily reflect the connection status between the computer on which it is Buy Waterbed running Buy New Car Online and Internet. The user Buy New Car Online may have the Buy New Car Online computer itself on-line, connected to Internet via Buy New Car Online a cable modem or an Buy New Car Online ADSL connection, but may wish for Outlook to be Buy New Car Online off-line, so that it makes no Buy New Car Online attempt to send or to receive messages. Or the computer may be configured to employ Buy New Car Online a dial-up connection on demand (whenever an application such as Outlook attempts to make connection to a server), but the connection may be Buy New Car Online an expensive telephone call from the Buy New Car Online particular location in which the computer currently happens to be (such as a hotel room) and the user may not wish Outlook to trigger making that Buy New Car Online call every 5 or 10 minutes to check for mail.
Another example of Buy New Car Online the use of these concepts is in the world of Buy New Car Online digital audio technology. A tape recorder, Buy New Car Online digital Buy New Car Online editor, or other device that is "on-line" is one whose clock is under the control of the clock of a "synchronization master" Buy New Car Online device. Buy New Car Online When the Buy New Car Online sync master commences Buy Your Slave In Oman playback, the "on-line" device automatically synchronizes itself Buy New Car Online to the master and commences playing from the same point in the recording. Buy New Car Online Whereas a device that is "off-line" uses no external clock reference and relies upon its Buy New Car Online own internal clock. Buy New Car Online When a large number of devices Buy New Car Online are connected to a sync master, it is often convenient, if one wants to hear just the output Buy New Car Online of one single device, to take it off-line, because if Buy New Car Online the device is played back on-line all synchronized devices have to locate the playback point and wait for each other to be Best Buy Employee Benifits 401k in synchronization.[2] (For further related discussion, see MIDI Buy New Car Online timecode, word sync, and recording system synchronization.)

A third example of a common use of these concepts is a web browser that can be Buy New Car Online instructed to be in either "on-line" or Buy Used Motorcyles Motor Bike Singapore "off-line" states. The browser only attempts to fetch pages Buy New Car Online from servers Buy New Car Online whilst in the "on-line" 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 Buy New Car Online useful when the computer itself is also off-line, with connection to Internet expensive or impossible. The pages are either downloaded implicitly into the Buy New Car Online web browser's Buy New Car Online own cache, as a result of prior on-line browsing by the user, or explicitly by Buy New Car Online 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 the Buy New Car Online local copies are up-to-date at regular intervals or by checking that the local copies are up-to-date whenever the browser is Buy New Car Online switched to the on-line state. One such web Buy New Car Online browser capable of Buy New Car Online being explicitly configured to download pages for offline browsing Buy New Car Online is Internet Explorer. When pages are added Buy New Car Online to the "Favourites" list, they can be marked for being Buy New Car Online made "available for offline browsing". Internet Explorer will download to local copies both Buy New Car Online the marked page and, optionally, all of the pages that it links Buy New Car Online to. In Internet Explorer version 6, the level of direct Buy New Car Online and indirect links, the maximum amount of local disc space allowed to be Buy New Car Online consumed, and the schedule on which local copies are checked to see whether they are up-to-date, are configurable for each
The ideas Buy New Car Online of "on-line" and "off-line" have been generalized from computing and telecommunication into the field of human interpersonal relationships. The distinction between what is considered "on-line" and what is considered "off-line" has become a subject of study Buy New Car Online in the field Buy New Car Online of sociology.[7]
The distinction between "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 Buy New Car Online virtuality, and "off-line" is reality (e.g. real life or meatspace). Slater states that this distinction is Buy New Car Online "obviously far too simple". To support his argument that the distinctions in relationships are more complex than Buy New Car Online a simple "on-line"/"off-line" dichotomy, he observes that some people draw no Buy New Car Online distinction Buy New Car Online between an Buy New Car Online "on-line" relationship, such Buy New Car Online 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 Buy New Car Online between Buy New Car Online the Buy New Car Online uses of various technologies (such Buy New Car Online as PDA Buy New Car Online 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 was employed by the first generation of Internet research".[7]

Slater asserts that there are legal and regulatory pressures Buy New Car Online to reduce the distinction between Buy New Car Online "on-line" and "off-line", with Buy Cialis Dreampharmaceuticals Online a "general tendency to assimilate online to offline and erase the distinction", Buy New Car Online stressing, however, that this does not mean that on-line relationships are being reduced to pre-existing off-line Buy New Car Online relationships. He conjectures that greater legal status may be assigned to on-line relationships (pointing out Buy New Car Online that contractual relationships, such as Buy New Car Online business transactions, on-line are already seen Buy New Car Online as just as "real" as their off-line Buy New Car Online counterparts), although he states it to be hard to imagine courts awarding palimony to people who Buy Generic Lipitor Online 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 Buy New Car Online not Buy New Car Online quite comprehensible" within 10 Buy New Car Online years
The distinction where Buy New Car Online "on-line" is seen as virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used Best Buy For Viagra to define and to explain "off-line" activities, rather than (as per the conventions of the desktop metaphor Buy New Car Online with its desktops, trash cans, Buy New Car Online folders, and so forth) the other way Buy New Car Online around. Several cartoons by The New Yorker have satirized this. One Buy New Car Online includes Buy New Car Online Saint Peter Buy New Car Online asking for a user name and a password before admitting Buy New Car Online a man into Heaven. Another illustrates "the off-line store" where Buy New Car Online "All items are actual size!", where shoppers may "Take it home as soon as you pay for it!", and Buy New Car Online where "Merchandise may be handled Buy New Car Online prior to purchase!". |
