One Crack Search Engine example Professional Search Engine Marketing of a common use Professional Search Engine Marketing of these concepts is Professional Search Engine Marketing a Mail User Agent that can be 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 Professional Search Engine Marketing mail Professional Search Engine Marketing servers (to check for new mail at regular intervals, for example), and when it is Professional Search Engine Marketing "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 connection status between the computer on which it is running and Internet. The user may have Search Engine Listing the computer itself on-line, connected Professional Search Engine Marketing to Internet via a cable Professional Search Engine Marketing modem or an ADSL connection, but may wish for Outlook to Professional Search Engine Marketing be off-line, so that it makes no attempt to Professional Search Engine Marketing send Professional Search Engine Marketing or to receive messages. Professional Search Engine Marketing Or the computer may 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 Professional Search Engine Marketing connection may be Professional Search Engine Marketing an Professional Search Engine Marketing expensive telephone call from the particular location in which the computer currently happens to be (such as a hotel room) and the user Professional Search Engine Marketing may not Professional Search Engine Marketing wish Outlook to Search Engine Registration trigger Professional Search Engine Marketing making that call every 5 or 10 minutes to check for mail.
Another Professional Search Engine Marketing example of the use of these concepts is in the world of digital audio technology. A tape recorder, digital editor, or other device that is Professional Search Engine Marketing "on-line" Professional Search Engine Marketing is Search Ck one whose clock is Professional Search Engine Marketing under the control of Professional Search Engine Marketing the clock of a "synchronization master" device. When the sync master commences playback, the "on-line" device automatically synchronizes itself to the master and Professional Search Engine Marketing commences playing from the same Professional Search Engine Marketing point in the Professional Search Engine Marketing recording. Whereas a device that is "off-line" uses no external clock reference and Professional Search Engine Marketing relies Professional Search Engine Marketing upon its own internal clock. When a large number of devices are connected to a sync master, it Professional Search Engine Marketing is often convenient, if one wants to hear just the output of one single Professional Search Engine Marketing device, to take it off-line, because if the device is played back on-line all synchronized devices have to locate the playback point Professional Search Engine Marketing and wait for each other to Professional Search Engine Marketing be in synchronization.[2] (For further related discussion, see MIDI timecode, word sync, and recording system synchronization.)
A third example of a common use Professional Search Engine Marketing of these concepts Professional Search Engine Marketing is a Professional Search Engine Marketing web browser that can Professional Search Engine Marketing be instructed to be in either "on-line" Professional Search Engine Marketing or Professional Search Engine Marketing "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 Professional Search Engine Marketing have previously been downloaded whilst in the "on-line" state. This can be useful when the computer itself is also off-line, with connection to Internet expensive Professional Search Engine Marketing 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 Professional Search Engine Marketing explicitly by the browser being configured to keep local copies of certain Professional Search Engine Marketing web pages, Professional Search Engine Marketing 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 intervals Professional Search Engine Marketing or by checking that the local copies are up-to-date Professional Search Engine Marketing whenever Professional Search Engine Marketing the browser is switched to the Professional Search Engine Marketing on-line state. One such web browser capable of Search Engiens being explicitly configured to download pages for offline browsing Professional Search Engine Marketing is Internet Explorer. When pages are added to the "Favourites" list, they can be marked for being made "available for offline browsing". Internet Explorer Professional Search Engine Marketing will download to local copies both the marked page and, optionally, all of the pages that it links to. In Internet Explorer version 6, the level of direct Professional Search Engine Marketing and indirect Professional Search Engine Marketing links, Professional Search Engine Marketing the maximum amount of local disc Professional Search Engine Marketing space allowed to be consumed, and the schedule on which local copies are checked to see whether they are up-to-date, Professional Search Engine Marketing are configurable for each
The ideas of "on-line" and "off-line" have been generalized from computing and telecommunication into the field of human interpersonal relationships. The distinction between what is considered "on-line" and what is considered "off-line" has become a subject of study in Professional Search Engine Marketing the Professional Search Engine Marketing field of sociology.[7]
The distinction between "on-line" and "off-line" is conventionally seen as the Professional Search Engine Marketing distinction between Professional Search Engine Marketing computer-mediated communication and face-to-face communication E Mail Search (e.g. face Professional Search Engine Marketing time), respectively. "On-line" is virtuality, and "off-line" is reality (e.g. real Professional Search Engine Marketing life or meatspace). Slater states that this distinction is "obviously far too Professional Search Engine Marketing simple". To support his argument that the distinctions in relationships are more complex than a simple Professional Search Engine Marketing "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between an "on-line" relationship, such as indulging in cybersex, Professional Search Engine Marketing and an "off-line" relationship, such as being pen-pals. He also argues that even Professional Search Engine Marketing the telephone can be Professional Search Engine Marketing regarded as an "on-line" experience Professional Search Engine Marketing in some circumstances, and that the blurring of the distinctions between the Professional Search Engine Marketing uses of various technologies (such as PDA and mobile telephone, television Professional Search Engine Marketing and Internet, and Professional Search Engine Marketing telephone Professional Search Engine Marketing 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 regulatory pressures to reduce the distinction between "on-line" and "off-line", with a "general tendency Professional Search Engine Marketing to assimilate online to offline and Professional Search Engine Marketing erase Professional Search Engine Marketing the distinction", stressing, however, that this does not mean that on-line relationships 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 Professional Search Engine Marketing are already seen as Professional Search Engine Marketing 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 Professional Search Engine Marketing 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 Professional Search Engine Marketing 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 Professional Search Engine Marketing conventions of the desktop metaphor with its desktops, trash cans, folders, and so forth) the Professional Search Engine Marketing other way around. Several cartoons Search Engine Ranking Optimization by The Professional Search Engine Marketing New Yorker have satirized this. Professional Search Engine Marketing One includes Saint Peter asking for a user name and a password before admitting a man into Heaven. Another illustrates "the off-line Professional Search Engine Marketing store" where "All items are actual Professional Search Engine Marketing size!", Professional Search Engine Marketing where shoppers may "Take it home as soon as you Professional Search Engine Marketing pay for it!", and where "Merchandise may be handled prior to purchase!". |
