In computer technology and telecommunications, online indicates a state of connectivity, and offline indicates a disconnected state. In modern terminology this usually refers to an Internet connection, but (especially when expressed 'on line' or 'on the line') could refer to any piece of equipment or functional unit that is connected to a larger system. Being online means that the equipment or subsystem is connected, or that it is ready for use.[1]
(Redirected from Offline)
'Online' has come to describe activities performed on and data available on the Internet,[2] for example: 'online identity', 'online predator', 'online gambling', 'online shopping', 'online banking', and 'online learning'. Similar meaning is also given by the prefixes 'cyber' and 'e', as in the words 'cyberspace', 'cybercrime', 'email', and 'ecommerce'.[3] In contrast, 'offline' can refer to either computing activities performed while disconnected from the Internet, or alternatives to Internet activities (such as shopping in brick-and-mortar stores). The term 'offline' is sometimes used interchangeably with the acronym 'IRL', meaning 'in real life'.[4]
Simple and easy to use, WikiTaxi is a portable application that you can use to download and read Wikipedia offline. It fully supports multiple language variations of Wikipedia, and even works with sister projects of Wikipedia, such as Wikitionary and Wikiquote. This is how you can download and use Wikipedia offline from a USB flash drive. Wikipedia can also be accessed offline using third-party software ( like XOWA ), but you cannot carry Wikipedia around with these software as you can do that by downloading it on a USB flash drive.
Antecedents[edit]
During the 19th century, the term 'on line' was commonly used in both the railroad and telegraph industries. For railroads, a signal box would send messages down the line (track), via a telegraph line (cable), indicating the track's status: 'Train on line' or 'Line clear'.[5] Telegraph linemen would refer to sending current through a line as 'direct on line' or 'battery on line';[6] or they may refer to a problem with the circuit as being 'on line', as opposed to the power source or end-point equipment.[7]
Examples[edit]Offline e-mail[edit]
One example of a common use of these concepts with email is a mail user agent (MUA) that can be instructed to be in either online or offline states. One such MUA is Microsoft Outlook. When online it will attempt to connect to mail servers (to check for new mail at regular intervals, for example), and when offline it will not attempt to make any such connection. The online or offline state of the MUA does not necessarily reflect the connection status between the computer on which it is running and the internet. That is, the computer itself may be onlineâconnected to Internet via a cable modem or other meansâwhile Outlook is kept offline by the user, so that it makes no attempt to send or to receive messages. Similarly, a computer may be configured to employ a dial-up connection on demand (as when an application such as Outlook attempts to make connection to a server), but the user may not wish for Outlook to trigger that call whenever it is configured to check for mail.[8]
Offline media playing[edit]
Another example of the use of these concepts is digital audio technology. A tape recorder, digital audio editor, or other device that is online is one whose clock is under the control of the clock of a synchronization master device. When the sync master commences playback, the online device automatically synchronizes itself to the master and commences playing from the same point in the recording. A device that is offline uses no external clock reference and relies upon its own internal clock. When a large number of devices are connected to a sync master it is often convenient, if one wants to hear just the output of one single device, to take it offline because, if the device is played back online, all synchronized devices have to locate the playback point and wait for each other device to be in synchronization.[9] (For related discussion, see MIDI timecode, word sync, and recording system synchronization.)
Offline browsing[edit]
A third example of a common use of these concepts is a web browser that can be instructed to be in either online or offline states. The browser attempts to fetch pages from servers while only in the online state. In the offline state, users can perform offline browsing, where pages can be browsed using local copies of those pages that have previously been downloaded while in the online state. This can be useful when the computer is offline and connection to the Internet is impossible or undesirable. The pages are downloaded either implicitly into the web browser's own cache as a result of prior online browsing by the user or explicitly by a browser configured to keep local copies of certain web pages, which are updated when the browser is in the online state, either by checking 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 to the online 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 to be 'available for offline browsing'. Internet Explorer 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 and indirect links, the maximum amount of local disc space allowed to be consumed, and the schedule on which local copies are checked to see whether they are up-to-date, are configurable for each individual Favourites entry.[10][11][12][13]
For communities that lack adequate Internet connectivityâsuch as developing countries, rural areas, and prisonsâoffline information stores such as the eGranary Digital Library (a collection of approximately thirty million educational resources from more than two thousand web sites and hundreds of CD-ROMs) provide offline access to information. Numerous organizations have developed, or are developing, flash memory chips with collections of educational materials for offline use in smartphones, tablets, and laptops.[citation needed]
Offline storage[edit]

Likewise, offline storage is computer data storage that is not 'available for immediate use on demand by the system without human intervention.' Additionally, an otherwise online system that is powered down may be considered offline.
Offline messages[edit]
Cara download game fifa 18 di laptop. With the growing communication tools and media, the words offline and online are used very frequently. If a person is active over a messaging tool and is able to accept the messages it is termed as online message and if the person is not available and the message is left to view when the person is back, it is termed as offline message. In the same context, the person's availability is termed as online and non-availability is termed as offline.
Generalisations[edit]
Online and offline distinctions have been generalised from computing and telecommunication into the field of human interpersonal relationships. The distinction between what is considered online and what is considered offline has become a subject of study in the field of sociology.[14]
The distinction between online and offline is conventionally seen as the distinction between computer-mediated communication and face-to-face communication (e.g., face time), respectively. Online is virtuality or cyberspace, and offline is reality (i.e., real life or meatspace). Slater states that this distinction is 'obviously far too simple'.[14] To support his argument that the distinctions in relationships are more complex than a simple dichotomy of online versus offline, he observes that some people draw no distinction between an online relationship, such as indulging in cybersex, and an offline relationship, such as being pen pals. He argues that even the telephone can be regarded as an online experience in some circumstances, and that the blurring of the distinctions between the uses of various technologies (such as PDA versus mobile phone, internet television versus internet, and telephone versus Voice over Internet Protocol) has made it 'impossible to use the term online meaningfully in the sense that was employed by the first generation of Internet research'.[14]
Slater asserts that there are legal and regulatory pressures to reduce the distinction between online and offline, with a 'general tendency to assimilate online to offline and erase the distinction,' stressing, however, that this does not mean that online relationships are being reduced to pre-existing offline relationships. He conjectures that greater legal status may be assigned to online relationships (pointing out that contractual relationships, such as business transactions, online are already seen as just as 'real' as their offline counterparts), although he states it to be hard to imagine courts awarding palimony to people who have had a purely online sexual relationship. He also conjectures that an online/offline distinction may be seen by people as 'rather quaint and not quite comprehensible' within 10 years.[14]
This distinction between online and offline is sometimes inverted, with online concepts being used to define and to explain offline activities, rather than (as per the conventions of the desktop metaphor with its desktops, trash cans, folders, and so forth) the other way around. Several cartoons appearing in The New Yorker have satirized this. One includes Saint Peter asking for a username and a password before admitting a man into Heaven. Another illustrates 'the off-line store' where 'All items are actual size!', shoppers may 'Take it home as soon as you pay for it!', and 'Merchandise may be handled prior to purchase!'[15][16]

An open source application automates the process of downloading and displaying all of Wikipedia on your desktop, a large task that takes more than a day to complete.
Dubbed Xowa, the software displays an offline copy of 4.4 million Wikipedia articles with full HTML formatting intact. You can even set up additional wikis, like Wiktionary or Wikquote, and navigate between them while offline. For example, you could 'Click on 'Look up this word in Wiktionary' and instantly view the page in Wiktionary.'
Xowa has been around for a while with support for 'Simple Wikipedia,' which has just a fraction of the full collaborative dictionary. It was updated yesterday with support for the entire English language-version of Wikipedia.
The SourceForge project page describes:
English Wikipedia has a lot of data. There are 13.9+ million pages with 20.0+ GB of text, as well as 3.7+ million thumbnails.
Setting all this up on your computer will not be a quick process.. The import itself will require 80GB of disk space and five hours processing time for the text version. If you want images as well, the numbers increase to 100GB of disk space and 30 hours of processing time. However, when you are done, you will have a complete, recent copy of English Wikipedia with images that can fit on a 128GB SD card.

Although at least 80GB of disk space is used during setup, the wiki files end up being reduced to 25GB after the deletion of a 45GB temporary file and other cleanup.
How To Download Wikipedia For Offline Use
Besides wiki data dumps and images from the Wikimedia Foundation, Xowa primarily consists of XUL Runner, a Firefox runtime environment; Java; and SWT, the Standard Widget Toolkit for Java.
If you want a download and setup that won't take an entire day, the Xowa developers recommend starting with Simple Wikipedia. 'Simple Wikipedia has 184,000 pages and 90,000 images,' Xowa writes. 'The text version uses 200MB and sets up in five minutes. With images, this expands to 2GB and 30 minutes of downloading time. Simple Wikipedia is a reasonably accurate simulation of English Wikipediaâjust much smaller.'
How To Download Wikipedia For Offline Use On Windows 10
Your Xowa-powered offline wiki, simple or not, can run on Windows, Linux, or OS X and can be updated any time from Wikimedia's database backups.
