One example of a Search Engine Optimisation Scotland 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 Search Engine Optimisation Scotland such MUA is Microsoft Outlook. When it 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" it will not Search Engine Optimisation Scotland attempt to make any such connections. The "on-line" Search Engine Optimisation Scotland or "off-line" state of the MUA does not Search Engine Optimisation Scotland necessarily reflect the connection status between the computer Search Engine Optimisation Scotland on which it is running and Internet. The user may have the computer itself on-line, connected to Internet via a cable modem or Search Engine Optimisation Scotland an ADSL connection, but may Search Engine Optimisation Scotland wish for Outlook to Search Engine Optimisation Scotland be off-line, so that it makes no attempt to send or to Search Engine Optimisation Scotland receive messages. Or the computer may be configured to employ a dial-up connection on demand (whenever an Search Engine Optimisation Scotland application such as Outlook attempts to make Search Engine Optimisation Scotland connection to a server), but the connection may be an expensive telephone call from the particular location Search Engine Optimisation Scotland in which the computer currently happens to Search Engine Optimisation Scotland be (such as a Search Engine Optimisation Scotland hotel room) and Search Engine Optimisation Scotland the user may not wish Outlook to Free Video Search trigger making that call every 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, Search Engine Optimisation Scotland or other device that is Search Engine Optimisation Scotland "on-line" Search Engine Optimisation Scotland is one whose clock is under the control of Search Engine Optimisation Scotland the clock Search Engine Optimisation Scotland of a "synchronization master" device. When the sync master commences playback, the "on-line" device automatically Search Engine Optimisation Scotland synchronizes itself to the master and commences playing from the same Clear Search History point in the recording. Whereas a device that is "off-line" uses no external clock reference and relies upon its own internal clock. Search Engine Optimisation Scotland When a large number of devices are connected to a sync master, it is often convenient, if one Search Engine Optimisation Scotland wants to hear just Search Engine Optimisation Scotland the output Search Engine Optimisation Scotland of one single device, to take it off-line, because if the Search Engine Optimisation Scotland device is played back on-line all synchronized Search Engine Optimisation Scotland devices have to locate Search Engine Optimisation Scotland the Search Engine Optimisation Scotland playback point and wait for each other to be in synchronization.[2] (For further related discussion, see Search Engine Optimisation Scotland MIDI timecode, word Search Engine Optimisation Scotland sync, and recording system Search Engine Optimisation Scotland Search Engine Positioning Company synchronization.)

A third example of a common use Search Engine Optimisation Scotland of these concepts is a web browser that can be Search Engine Optimisation Scotland instructed to be in either "on-line" or "off-line" states. The browser only attempts to fetch pages from Search Engine Optimisation Scotland servers whilst in the "on-line" state. Search Engine Optimisation Scotland In the "off-line" state, users can perform offline browsing, where pages can be browsed using Search Engine Optimisation Scotland local copies of those pages Search Engine Optimisation Scotland that have previously been downloaded whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with Search Engine Optimisation Scotland connection to Internet expensive or impossible. The pages are either downloaded implicitly into the web browser's own cache, as a result Search Engine Optimisation Scotland of prior on-line browsing by the Search Engine Optimisation Scotland user, or explicitly by the browser being configured to keep local copies of Search Engine Optimisation Scotland certain 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 Search Engine Optimisation Scotland intervals or Search Engine Optimisation Scotland by checking that Search Engine Optimisation Scotland Plant Search the local copies are up-to-date whenever the browser is switched to the on-line state. Search Engine Optimisation Scotland One such web browser capable of being explicitly configured to download pages for offline browsing is Internet Explorer. Search Engine Optimisation Scotland When pages are Search Engine Optimisation Scotland added to the "Favourites" list, they can be marked for being made "available for offline browsing". Internet Explorer will download to local copies Search Engine Optimisation Scotland both the marked page Search Engine Optimisation Scotland and, optionally, all of the pages that it links to. In Internet Explorer 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 Search Engine Optimisation Scotland 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 Search Engine Optimisation Scotland telecommunication into the field of human interpersonal relationships. The distinction between what is considered Search Engine Optimisation Scotland "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 Search Engine Optimisation Scotland conventionally seen as the distinction between computer-mediated Search Windows Xp Update communication and face-to-face communication (e.g. face time), respectively. "On-line" is virtuality, and "off-line" is reality (e.g. real Search Engine Optimisation Scotland life or meatspace). Slater states that this distinction is "obviously far too simple". To support his argument that 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 Make Own Word Search as Search Engine Optimisation Scotland 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 Search Engine Optimisation Scotland some Search Engine Optimisation Scotland circumstances, and that the Search Resumes blurring Search Engine Optimisation Scotland of the distinctions between the uses Search Engine Optimisation Scotland of various technologies (such as Search Engine Optimisation Scotland PDA and mobile telephone, television and Internet, and telephone and voice-over-IP) Search Engine Optimisation Scotland has made it Search Engine Optimisation Scotland "impossible to use the term 'on-line' meaningfully in Search Engine Optimisation Scotland the sense that was employed by the first generation of Search Engine Optimisation Scotland Internet research".[7]

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