One Best Travel Nurse Position example of a common use of these concepts is a Mail User Agent that can Best Travel Nurse Position be Best Travel Nurse Position 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 connect to mail servers (to check for new mail Best Travel Nurse Position at regular intervals, for example), and when it is "off-line" it will not attempt to make any such connections. The Best Travel Nurse Position "on-line" Best Travel Nurse Position or "off-line" state of the Best Travel Nurse Position MUA does not necessarily reflect the 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 ADSL connection, but may wish for Best Travel Nurse Position Outlook to Best Travel Nurse Position be off-line, so that it makes no attempt to Best Travel Nurse Position send or Best Travel Nurse Position to receive messages. Or Best Travel Nurse Position the computer may Best Ipod Speaker 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 telephone Best Travel Nurse Position call from the particular location in which the computer Best Travel Nurse Position currently happens to be (such as a Best Travel Nurse Position hotel room) and the user may not wish Outlook to trigger making that call every 5 or 10 minutes to check Best Travel Nurse Position for mail.
Another example Best Travel Nurse Position of the use of these Best Travel Nurse Position concepts is in the world of Best Travel Nurse Position digital audio technology. A tape recorder, digital editor, or other device that is "on-line" is one whose clock is under the control of the clock of a "synchronization master" device. When the sync master commences playback, the "on-line" device automatically synchronizes itself to the master and Best Travel Nurse Position commences playing from the same point in Best Travel Nurse Position the recording. Whereas a device that is "off-line" uses no external clock Best Travel Nurse Position reference and relies upon its own internal clock. When a large number of Best Travel Nurse Position devices are connected to a sync master, it is often convenient, if one wants to Best Travel Nurse Position hear just the output of one single Best Travel Nurse Position device, to take it off-line, Best Travel Nurse Position because if the device Best Rechargeable Batteries is played back on-line all synchronized devices have to locate the playback point and wait for each other Best Travel Nurse Position to be in synchronization.[2] (For further related discussion, see MIDI timecode, Best Travel Nurse Position word sync, and recording system synchronization.)
A third example of a common use of Best Travel Nurse Position these concepts is a web browser that can be instructed to be in either "on-line" or "off-line" Best Travel Nurse Position states. The browser only attempts Best Travel Nurse Position to fetch pages from servers whilst in the "on-line" state. In the "off-line" state, users can perform offline browsing, where pages Best Travel Nurse Position can be browsed using local copies of those pages that have previously been downloaded Best Travel Nurse Position whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with connection to Internet expensive or impossible. The pages are either Best Travel Nurse Position downloaded implicitly into the web browser's own cache, as Best Weight Loss Tip a result of prior on-line browsing Best Techno Songs Ever by the user, or explicitly by the browser being configured to keep local copies of Best Travel Nurse Position certain web pages, which Best Travel Nurse Position it keeps updated Best Travel Nurse Position when the browser is in the on-line state, either by checking Best Travel Nurse Position 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 Best Diet Drink to the on-line state. One such web browser capable of being explicitly Best Travel Nurse Position 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". Best Travel Nurse Position Internet Explorer will download to local copies both the marked Best Travel Nurse Position page Best Travel Nurse Position and, optionally, all of the pages that it links to. In Best Travel Nurse Position Internet Explorer version 6, the Best Travel Nurse Position level of direct and indirect links, the maximum amount of local disc space Best Travel Nurse Position allowed to be consumed, and the schedule on which Best Travel Nurse Position 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 telecommunication into Best Travel Nurse Position the field of human interpersonal relationships. The distinction between what is considered Best Travel Nurse Position "on-line" and what is considered "off-line" has become Best Travel Nurse Position a subject of study in the field of sociology.[7]
The Best Travel Nurse Position 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 virtuality, and "off-line" is reality (e.g. real life or meatspace). Slater states that Best Travel Nurse Position this distinction is "obviously far too simple". To support his argument that the Best Travel Nurse Position distinctions in relationships are more complex than a simple Online Best Offer Weight Loss Diets "on-line"/"off-line" dichotomy, he observes Best Travel Nurse Position that some people Best Travel Nurse Position draw no distinction between an "on-line" Best Travel Nurse Position relationship, such as indulging in cybersex, and an "off-line" relationship, such Best Travel Nurse Position as being pen-pals. He also argues Best Travel Nurse Position that even the telephone can be regarded as an "on-line" experience in some circumstances, and that Best Travel Nurse Position Nicola Best the blurring of the distinctions between the uses Best Travel Nurse Position of various technologies (such as PDA and mobile telephone, television Best Travel Nurse Position and Internet, and telephone and voice-over-IP) Best Travel Nurse Position has made it "impossible to use the Best Travel Nurse Position term 'on-line' meaningfully in the sense that was employed by the first generation of Internet research".[7]
Slater asserts that there are Best Travel Nurse Position legal and regulatory pressures to reduce the distinction between "on-line" and "off-line", with a Best Travel Nurse Position "general tendency to assimilate online to offline Best Travel Nurse Position and erase the distinction", stressing, however, that this does not mean that on-line relationships are being Best Travel Nurse Position reduced to pre-existing off-line Best Travel Nurse Position relationships. He conjectures Best Travel Nurse Position that greater legal status may Best Travel Nurse Position be assigned Best Travel Nurse Position to on-line relationships (pointing out that contractual relationships, such as business transactions, on-line are already seen as just as "real" as their off-line counterparts), although Best Travel Nurse Position he states it to be hard to imagine courts awarding palimony to people who have had a purely on-line sexual relationship. He Best Travel Nurse Position 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 "on-line" is seen as virtuality and "off-line" as reality is sometimes inverted, with "on-line" concepts being used to Best Travel Nurse Position define and Best Travel Nurse Position to explain "off-line" activities, Best Travel Nurse Position rather than (as Best Travel Nurse Position per the Best Travel Nurse Position conventions of Best Travel Nurse Position the desktop metaphor with its desktops, Best Travel Nurse Position trash cans, Best Travel Nurse Position folders, and so forth) the other way around. Several cartoons by The New Yorker have Best Travel Nurse Position satirized this. One includes Saint Peter asking for a user name and a password before admitting a man into Heaven. Another illustrates "the off-line store" where "All items are actual size!", where shoppers Best Travel Nurse Position may Best Travel Nurse Position "Take it home as Best Travel Nurse Position soon as you pay for Best Travel Nurse Position it!", and where "Merchandise may be handled prior to purchase!". |
