One example of America Best Eye a common use of these concepts is a Mail User Agent that can be instructed to be in either America Best Eye "on-line" or "off-line" states. One such MUA is Microsoft Outlook. When it is "on-line" it will attempt to connect to America Best Eye mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" it will not attempt to make America Best Eye any such connections. The "on-line" or "off-line" state America Best Eye of the MUA does not necessarily reflect the connection status between the America Best Eye computer America Best Eye on which it is running and Internet. The user may have the computer itself on-line, connected to Internet via a cable America Best Eye modem or an ADSL connection, but may wish for Outlook to be off-line, so that it makes Best Rated Motherboard no attempt to send or to receive messages. America Best Eye Or the computer may be configured to employ a dial-up connection on demand (whenever America Best Eye an application such as Outlook attempts to make connection to a server), America Best Eye but the connection may be an expensive telephone America Best Eye call from the particular America Best Eye location in America Best Eye which the computer America Best Eye 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 America Best Eye the use of these concepts is in the world America Best Eye of digital audio technology. A Best Of Tallahassee tape recorder, digital editor, or other device that America Best Eye is "on-line" is one whose America Best Eye clock is under the control of the clock of a "synchronization master" America Best Eye device. When the sync America Best Eye master commences playback, the "on-line" America Best Eye device automatically synchronizes itself to the master and commences playing America Best Eye from America Best Eye the same point in the recording. Whereas a device that is "off-line" uses no external clock reference and America Best Eye relies upon its own internal clock. When a large number of devices are connected to a sync master, it is often convenient, if one wants to America Best Eye hear just the output of one single device, to Best Momentum Stock Trading take it off-line, because America Best Eye if the device is played back America Best Eye on-line all synchronized devices have to locate the playback America Best Eye point and wait for each other to be 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 America Best Eye web America Best Eye browser that can be instructed to be in either America Best Eye "on-line" or "off-line" states. The browser only attempts to fetch 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 America Best Eye whilst in the "on-line" state. This can America Best Eye be useful when the computer Best Snowboard Bindings itself is also off-line, with America Best Eye connection to Internet expensive or impossible. The pages are either downloaded America Best Eye implicitly into America Best Eye the web browser's own cache, as a result of prior on-line browsing America Best Eye by the user, or explicitly by the browser being configured to keep local copies of certain America Best Eye web pages, which 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 America Best Eye intervals or by checking America Best Eye that the local copies are up-to-date whenever the browser is America Best Eye switched to the on-line state. One such web browser capable of being explicitly configured to download pages for offline browsing America Best Eye is Internet 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 America Best Eye copies both the marked page and, optionally, all of the pages that it links to. In Internet Explorer America Best Eye version 6, the level of direct and indirect links, the maximum amount of local disc space allowed to be consumed, and the schedule on which local copies are checked to see whether they are up-to-date, are configurable for each

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