One example of a common use of these concepts is a Mail User Agent that can be instructed to be in either "on-line" or "off-line" states. Optimization Search Engines One such MUA is Microsoft Outlook. Optimization Search Engines When Optimization Search Engines it is "on-line" it will attempt to Optimization Search Engines connect to mail servers (to check for new mail at regular intervals, for example), and when it is "off-line" it Optimization Search Engines will not attempt Optimization Search Engines to make any such connections. The Optimization Search Engines "on-line" or "off-line" state of the MUA does not necessarily reflect the Optimization Search Engines connection status between the computer on which it is running and Internet. The user may have Optimization Search Engines the computer itself Optimization Search Engines on-line, connected to Internet via a cable modem Optimization Search Engines or Optimization Search Engines an ADSL Optimization Search Engines connection, but may wish for Outlook to be off-line, so that it makes no attempt to send or to receive messages. Or the computer may be configured to employ a dial-up connection on demand (whenever an application such Optimization Search Engines as Outlook attempts to make connection to a server), but the connection may be an expensive telephone call from the particular location in which Optimization Search Engines the computer currently happens to be (such Optimization Search Engines as a hotel room) and the user may Optimization Search Engines not wish Outlook to Optimization Search Engines trigger making Optimization Search Engines that call every 5 or Optimization Search Engines 10 minutes to check for mail.
Another example of the use Optimization Search Engines of these concepts is in the world of digital audio technology. A tape recorder, digital editor, or other device Optimization Search Engines that is "on-line" is one whose Optimization Search Engines clock Optimization Search Engines is under the control of the clock of a "synchronization master" device. When the Optimization Search Engines sync master commences playback, the Naughty Search "on-line" device automatically synchronizes Optimization Search Engines itself to the master and Search Atorvastatin Infocouk commences playing from the same point in the recording. Whereas a device that is "off-line" Optimization Search Engines uses no external clock reference and relies upon its own Optimization Search Engines internal clock. When a large number of devices are connected to a sync master, it is often convenient, if Optimization Search Engines one wants to hear just the output of one Toy Search Engine single device, to take it off-line, because Optimization Search Engines if the device is played back on-line Optimization Search Engines all synchronized devices have to locate Deep Search the playback point and wait for each other to be in synchronization.[2] (For further related discussion, see Optimization Search Engines MIDI timecode, word sync, and recording system synchronization.)
A third example of a common use Optimization Search Engines of these concepts is a web browser that can be instructed to be in either "on-line" or "off-line" states. The browser only attempts to fetch pages from Yahoo Uk Search servers whilst in the "on-line" state. In the "off-line" state, users can perform offline browsing, where pages Optimization Search Engines can be browsed using local copies of those Optimization Search Engines pages that Optimization Search Engines have previously been downloaded whilst in the "on-line" state. This can be useful Optimization Search Engines when Optimization Search Engines the computer itself is also Optimization Search Engines off-line, with connection to Internet expensive or impossible. The pages are either downloaded implicitly into the web Search For Phone Numbers browser's own Optimization Search Engines cache, as a result of prior Optimization Search Engines on-line browsing by the user, or explicitly by the browser being configured to keep local copies of certain web pages, which it keeps updated when the browser is in Optimization Search Engines the on-line state, either Job Search Singapore by checking that the local copies are up-to-date at regular intervals or by checking that Optimization Search Engines the local Optimization Search Engines copies are up-to-date whenever the browser is switched to the on-line state. One such web browser capable Optimization Search Engines of being Optimization Search Engines explicitly configured to Optimization Search Engines download pages for offline browsing is Internet Explorer. Optimization Search Engines When pages are added to the Optimization Search Engines "Favourites" list, they can be marked for being made "available for offline browsing". Internet Explorer will download to local copies both the marked page Fictitious Name Search and, optionally, all of the pages that it links Optimization Search Engines to. In Internet Explorer Optimization Search Engines version 6, the level of direct and indirect links, Optimization Search Engines the maximum amount of local disc space allowed to be consumed, and the Optimization Search Engines schedule on which local copies are checked to Lookout Search see whether they are up-to-date, are Optimization Search Engines configurable for Optimization Search Engines each
The ideas of Search By Area Code "on-line" Optimization Search Engines and "off-line" have been generalized from computing and telecommunication into Optimization Search Engines the field of human interpersonal relationships. The distinction between what is considered "on-line" and what is considered "off-line" has Optimization Search Engines become a subject of study in the field of sociology.[7]
The distinction between "on-line" and "off-line" is Optimization Search Engines conventionally seen as the distinction between computer-mediated communication and face-to-face communication (e.g. Optimization Search Engines face time), respectively. Optimization Search Engines "On-line" is virtuality, and "off-line" is Optimization Search Engines reality (e.g. real life Optimization Search Engines or meatspace). Slater states that this distinction is "obviously Optimization Search Engines far too simple". To support his argument that the distinctions in relationships are more complex than Optimization Search Engines a Optimization Search Engines simple "on-line"/"off-line" dichotomy, he observes that some people draw no distinction between an "on-line" relationship, such as 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" Optimization Search Engines experience in some circumstances, and that the blurring of the distinctions between the uses of Optimization Search Engines various technologies (such as PDA and mobile telephone, television and Optimization Search Engines Internet, and telephone and voice-over-IP) has made it "impossible to use the term 'on-line' meaningfully in the Optimization Search Engines sense that was employed by Optimization Search Engines the first generation of Internet research".[7]
Slater asserts that there are legal and regulatory pressures Optimization Search Engines to reduce the distinction between "on-line" and "off-line", with a "general tendency Scientific Search Engine to assimilate online to offline and erase the Optimization Search Engines 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 Optimization Search Engines be assigned to on-line relationships (pointing out that contractual relationships, such as business transactions, on-line are already seen as just as Optimization Search Engines "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 Optimization Search Engines on-line sexual relationship. He also conjectures that an "on-line"/"off-line" distinction may be seen Best Search Sites by people as "rather Optimization Search Engines quaint and not Optimization Search Engines 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 define and to explain Optimization Search Engines "off-line" activities, rather than (as per the conventions of the desktop metaphor with its Optimization Search Engines desktops, trash cans, folders, and so forth) the other way around. Several cartoons by The New Yorker have satirized this. One includes Optimization Search Engines Saint Peter asking for a user name Optimization Search Engines 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 it!", and Optimization Search Engines where "Merchandise may be handled prior Optimization Search Engines to Optimization Search Engines purchase!". |
