| One example of a common use of these concepts is a Mail User Agent that can What Is The Best Hunting Crossbow be instructed to be Reviews Best Antivirus in Reviews Best Antivirus either "on-line" or "off-line" states. One Reviews Best Antivirus such Reviews Best Antivirus MUA Reviews Best Antivirus is Microsoft Outlook. Reviews Best Antivirus When Reviews Best Antivirus it is "on-line" it will Reviews Best Antivirus attempt to connect to mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" it will not attempt to make any such connections. The "on-line" or "off-line" state of the MUA does not necessarily reflect the Reviews Best Antivirus connection status Reviews Best Antivirus 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 ADSL connection, but may wish for Outlook Reviews Best Antivirus to be off-line, so that it makes no attempt to send Reviews Best Antivirus or to receive messages. Or the computer may be Reviews Best Antivirus configured to employ a dial-up connection on Reviews Best Antivirus demand (whenever an application Reviews Best Antivirus such as Outlook attempts 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 (such as a hotel room) and Reviews Best Antivirus the user Reviews Best Antivirus may not wish Outlook to trigger making that call every 5 or 10 Best Dental Search Sites minutes to Reviews Best Antivirus check Reviews Best Antivirus for mail.
Another example of the use of Reviews Best Antivirus these concepts is in the world Reviews Best Antivirus of digital audio technology. A tape recorder, digital editor, or other device that is "on-line" is Reviews Best Antivirus one whose clock is under the Reviews Best Antivirus control of the clock of a Reviews Best Antivirus "synchronization master" device. When the Reviews Best Antivirus sync master Reviews Best Antivirus commences playback, the "on-line" device automatically synchronizes itself to the master and commences playing from the same point in the recording. Whereas a device Reviews Best Antivirus that is "off-line" uses no external clock reference and relies upon its own internal clock. When a large number Reviews Best Antivirus of devices are connected to a sync master, it is often Reviews Best Antivirus convenient, if one wants to Reviews Best Antivirus hear just Reviews Best Antivirus the output of one single device, Reviews Best Antivirus to take it off-line, because if the device is played back on-line Best Price Sr22 Car Insurance Uk all synchronized devices have to locate the playback point and wait for each other to be Reviews Best Antivirus in synchronization.[2] (For further related discussion, see MIDI timecode, word sync, and recording system synchronization.)

A third Reviews Best Antivirus example of Reviews Best Antivirus a common use of these concepts is a web browser that can Reviews Best Antivirus be instructed to be in either "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 Reviews Best Antivirus previously been downloaded whilst in the "on-line" state. This can be useful when the computer itself Reviews Best Antivirus is also off-line, with connection to Internet Reviews Best Antivirus expensive Reviews Best Antivirus or impossible. The pages are either downloaded implicitly into Reviews Best Antivirus 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 Reviews Best Antivirus web pages, which it keeps updated when the browser is in the on-line state, Reviews Best Antivirus either by checking that the local copies are up-to-date at Reviews Best Antivirus regular intervals or by checking that the local copies are up-to-date whenever the browser Reviews Best Antivirus is switched to the on-line state. 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 marked for being made "available for offline browsing". Reviews Best Antivirus Internet Reviews Best Antivirus Explorer will download to Reviews Best Antivirus local copies both the Reviews Best Antivirus marked page and, optionally, all of the pages Reviews Best Antivirus that it links to. In Internet Explorer Reviews Best Antivirus version Best Pizza Crust 6, the level of direct and indirect links, the maximum amount of local Reviews Best Antivirus disc space allowed to Reviews Best Antivirus be consumed, and the schedule Reviews Best Antivirus on which local copies are checked to see whether they are up-to-date, are configurable for Reviews Best Antivirus each
The ideas Reviews Best Antivirus of "on-line" and "off-line" have been generalized from computing and telecommunication into the field of human interpersonal relationships. Reviews Best Antivirus 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 Reviews Best Antivirus distinction between Reviews Best Antivirus "on-line" and "off-line" is conventionally seen as the distinction between computer-mediated communication Reviews Best Antivirus and Reviews Best Antivirus face-to-face Reviews Best Antivirus communication (e.g. face time), respectively. "On-line" is virtuality, and "off-line" is reality (e.g. real Reviews Best Antivirus life or meatspace). Reviews Best Antivirus Slater states that this distinction is "obviously far too simple". To support his argument that Reviews Best Antivirus the distinctions in relationships are more complex than a simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between an "on-line" relationship, such as indulging Reviews Best Antivirus in cybersex, and an "off-line" relationship, such as being pen-pals. Reviews Best Antivirus He also argues that even the telephone can be regarded as an "on-line" experience in some circumstances, and that the blurring Best Nude Adult Website of the distinctions between the uses of various technologies (such as PDA and mobile telephone, television and Internet, and Reviews Best Antivirus 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 Reviews Best Antivirus regulatory pressures to reduce the distinction between "on-line" and "off-line", with a "general tendency to assimilate online to offline and erase Reviews Best Antivirus the distinction", stressing, however, that this does not mean that on-line relationships are being reduced to pre-existing off-line relationships. Best Band In The World He conjectures that greater legal status may be assigned to on-line relationships (pointing Reviews Best Antivirus out that contractual relationships, such as business transactions, on-line are already seen as just as "real" as their off-line counterparts), although he states it to be hard to imagine courts awarding palimony to people who have had a purely on-line sexual relationship. He also Reviews Best Antivirus conjectures that an "on-line"/"off-line" distinction may be seen Reviews Best Antivirus by people as Reviews Best Antivirus "rather quaint and not quite Reviews Best Antivirus comprehensible" Reviews Best Antivirus within Reviews Best Antivirus 10 Reviews Best Antivirus years
The distinction where "on-line" is seen Reviews Best Antivirus as Reviews Best Antivirus virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used to define and to explain "off-line" Best Home Based Business Ideas activities, rather than (as per the conventions of the desktop metaphor with its Reviews Best Antivirus desktops, trash cans, folders, and so forth) the other way around. Several Reviews Best Antivirus cartoons by The New Yorker have satirized this. One includes Saint Peter asking for a user Reviews Best Antivirus name and a password before admitting a man into Heaven. Another illustrates "the off-line store" where "All items are actual size!", where shoppers may "Take it home as soon as you pay for Reviews Best Antivirus it!", and where "Merchandise Reviews Best Antivirus may be handled prior to purchase!". |
