One Best Tandem Axle Trailers example of a common Best Tandem Axle Trailers use of these concepts is a Who Makes The Best Laptop Computer Mail User Agent that can be instructed to be in either "on-line" or "off-line" states. Best Tandem Axle Trailers One such MUA is Microsoft Outlook. When it Best Tandem Axle Trailers 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" Best Tandem Axle Trailers it will not attempt to Best Online Diet Program make Best Tandem Axle Trailers any such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect Best Tandem Axle Trailers the connection status between the computer on which it Best Tandem Axle Trailers is running and Internet. The Best Tandem Axle Trailers user may have the computer itself on-line, connected Best Tandem Axle Trailers to Internet via a cable modem or an ADSL connection, but may wish for Outlook to be off-line, so 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 Best Tandem Axle Trailers to make connection to a server), but the connection may be an expensive telephone call from the particular location in which the computer currently happens to be Best Tandem Axle Trailers (such as a Best Tandem Axle Trailers hotel room) and the user may not wish Outlook to Best Tandem Axle Trailers trigger making that call every Best Tandem Axle Trailers 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 editor, Best Tandem Axle Trailers or other device that is "on-line" is one whose clock is under the control of the clock Best Tandem Axle Trailers of a "synchronization master" device. When the sync master Best Tandem Axle Trailers commences playback, the "on-line" device automatically Best Tandem Axle Trailers synchronizes itself to the master and Best Tandem Axle Trailers commences 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 Best Tandem Axle Trailers a large number of devices are connected to a sync master, it Best Tandem Axle Trailers is often Best Tandem Axle Trailers convenient, Best Vacuum Cleaner On The Market if Best Halloween Costume Ever one wants to hear just the output of one single device, to take Best Tandem Axle Trailers it off-line, because if the device is played back on-line all synchronized devices Best Tandem Axle Trailers have to Best Tandem Axle Trailers locate the playback point and wait for each other to Best Tandem Axle Trailers be in synchronization.[2] (For further related discussion, see MIDI timecode, Best Tandem Axle Trailers word Best Tandem Axle Trailers sync, and recording system synchronization.)
A third Best Tandem Axle Trailers example of a common use of these concepts is a web browser that can be instructed to be Best Tandem Axle Trailers in Best Tandem Axle Trailers either "on-line" or "off-line" states. The browser only attempts to fetch Acne Best Prone Sensitive Skin Treatment pages from servers 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 Best Tandem Axle Trailers in the "on-line" state. This can be useful when the computer itself Best Tandem Axle Trailers is also off-line, with connection Best Tandem Axle Trailers to Best Tandem Axle Trailers 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 by the user, or explicitly by the browser being configured to keep local copies of certain web pages, which it keeps updated when the Best Tandem Axle Trailers browser is Best Tandem Axle Trailers 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 The Best Prepaid Cell Phone Service switched to the on-line state. Best Tandem Axle Trailers One such web browser capable of being explicitly configured to download pages for offline browsing is Internet Explorer. When pages are added to the "Favourites" list, they can be Best Tandem Axle Trailers marked for being made "available for Best Tandem Axle Trailers offline browsing". Internet Explorer will download to local copies both Best Tandem Axle Trailers the marked page and, optionally, all of the pages that it links to. Best Tandem Axle Trailers In Internet Explorer version 6, the level of direct and indirect links, the maximum amount of local Best Tandem Axle Trailers disc space allowed to be consumed, and the Best Tandem Axle Trailers schedule on which local copies are checked to see whether they are up-to-date, Best Tandem Axle Trailers are configurable for each

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