Instant messaging - Wikipedia, the free encyclopedia. Instant messaging (IM) is a type of online chat which offers real- time text transmission over the Internet. A LAN messenger operates in a similar way over a local area network. Short messages are typically transmitted bi- directionally between two parties, when each user chooses to complete a thought and select . Some IM applications can use push technology to provide real- time text, which transmits messages character by character, as they are composed. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat. Non- IM types of chat include multicast transmission, usually referred to as . Instant messaging systems tend to facilitate connections between specified known users (often using a contact list also known as a . Depending on the IM protocol, the technical architecture can be peer- to- peer (direct point- to- point transmission) or client- server (a central server retransmits messages from the sender to the communication device). Overview. Of importance is that online chat and instant messaging differ from other technologies such as email due to the perceived quasi- synchrony of the communications by the users. Some systems permit messages to be sent to users not then 'logged on' (offline messages), thus removing some differences between IM and email (often done by sending the message to the associated email account). One such instant messaging service. Check out the infographic below for stats on the top instant message apps around. Technology Smartphones Apps App. Download IM+ Instant Messenger and enjoy. Programs; Apple Store. IM allows effective and efficient communication, allowing immediate receipt of acknowledgment or reply. However IM is basically not necessarily supported by transaction control. In many cases, instant messaging includes added features which can make it even more popular. For example, users may see each other via webcams, or talk directly for free over the Internet using a microphone and headphones or loudspeakers. Many applications allow file transfers, although they are usually limited in the permissible file- size. It is usually possible to save a text conversation for later reference. Instant messages are often logged in a local message history, making it similar to the persistent nature of emails. History. Initially, some of these systems were used as notification systems for services like printing, but quickly were used to facilitate communication with other users logged into the same machine. As networks developed, the protocols spread with the networks. Some of these used a peer- to- peer protocol (e. The Zephyr Notification Service (still in use at some institutions) was invented at MIT's Project Athena in the 1. Parallel to instant messaging were early online chat facilities, the earliest of which was Talkomatic (1. PLATO system. During the bulletin board system (BBS) phenomenon that peaked during the 1. Freelancin' Roundtable was one prime example. This includes the Unix . Some BBS chat programs (i. Celerity BBS) also used a similar interface. Modern implementations of real- time text also exist in instant messengers, such as AOL's Real- Time IM. While the Quantum Link client software ran on a Commodore 6. Commodore's PETSCII text- graphics, the screen was visually divided into sections and OLMs would appear as a yellow bar saying . OLMs were what Q- Link called . Similar functionality was offered by CU- See. Me in 1. 99. 2; though primarily an audio/video chat link, users could also send textual messages to each other. AOL later acquired Mirabilis, the authors of ICQ; a few years later ICQ (now owned by AOL) was awarded two patents for instant messaging by the U. S. Meanwhile, other companies developed their own software; (Excite, MSN, Ubique, and Yahoo!), each with its own proprietaryprotocol and client; users therefore had to run multiple client applications if they wished to use more than one of these networks. In 1. 99. 8, IBM released IBM Lotus Sametime, a product based on technology acquired when IBM bought Haifa- based Ubique and Lexington- based Databeam. In 2. 00. 0, an open source application and open standards- based protocol called Jabber was launched. The protocol was standardized under the name Extensible Messaging and Presence Protocol (XMPP). XMPP servers could act as gateways to other IM protocols, reducing the need to run multiple clients. Multi- protocol clients can use any of the popular IM protocols by using additional local libraries for each protocol. IBM Lotus Sametime's November 2. IBM Lotus Sametime Gateway support for XMPP. As of 2. 01. 0, social networking providers often offer IM abilities. Facebook Chat is a form of instant messaging, and Twitter can be thought of as a Web 2. Similar server- side chat features are part of most dating websites, such as OKCupid or Plentyof. Fish. The spread of smartphones and similar devices in the late 2. Many instant messaging services offer video calling features, voice over IP and web conferencing services. Web conferencing services can integrate both video calling and instant messaging abilities. Some instant messaging companies are also offering desktop sharing, IP radio, and IPTV to the voice and video features. The term . For this reason, in April 2. Gaim (or gaim) announced that they would be renamed . These usually only work with the supplier company's service, although some allow limited function with other services. Third party client software applications exist that will connect with most of the major IM services. Interoperability. These may be all the functions that a small business needs, but larger organizations will require more sophisticated applications that can work together. The solution to finding applications capable of this is to use enterprise versions of instant messaging applications. SMS: Choosing the Right One. By Tony Bradley, PCWorld.

These include titles like XMPP, Lotus Sametime, Microsoft Office Communicator, etc., which are often integrated with other enterprise applications such as workflow systems. These enterprise applications, or enterprise application integration (EAI), are built to certain constraints, namely storing data in a common format. There have been several attempts to create a unified standard for instant messaging: IETF's Session Initiation Protocol (SIP) and SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Application Exchange (APEX), Instant Messaging and Presence Protocol (IMPP), the open XML- based Extensible Messaging and Presence Protocol (XMPP), and Open Mobile Alliance's Instant Messaging and Presence Service developed specifically for mobile devices. Most attempts at producing a unified standard for the major IM providers (AOL, Yahoo! This agreement enabled AIM, ICQ and MSN Messenger users to talk with Reuters Messaging counterparts and vice versa. Following this, Microsoft, Yahoo! This deal established SIP/SIMPLE as a standard for protocol interoperability and established a connectivity fee for accessing public instant messaging groups or services. Separately, on October 1. Microsoft and Yahoo! This approach moves the task of communicating with the other services to the server. Clients need not know or care about other IM protocols. For example, LCS 2. Public IM Connectivity. This approach is popular in XMPP servers; however, the so- called transport projects suffer the same reverse engineering difficulties as any other project involved with closed protocols or formats. Some approaches allow organizations to deploy their own, private instant messaging network by enabling them to restrict access to the server (often with the IM network entirely behind their firewall) and administer user permissions. Other corporate messaging systems allow registered users to also connect from outside the corporation LAN, by using an encrypted, firewall- friendly, HTTPS- based protocol. Usually, a dedicated corporate IM server has several advantages, such as pre- populated contact lists, integrated authentication, and better security and privacy. Certain networks have made changes to prevent them from being used by such multi- network IM clients. For example, Trillian had to release several revisions and patches to allow its users to access the MSN, AOL, and Yahoo! The major IM providers usually cite the need for formal agreements, and security concerns as reasons for making these changes. The use of proprietary protocols has meant that many instant messaging networks have been incompatible and users have been unable to reach users on other networks. The language has become widespread, with well- known expressions such as 'lol' translated over to face- to- face language. Emotions are often expressed in shorthand, such as the abbreviation LOL, BRB and TTYL; respectively laugh(ing) out loud, be right back, and talk to you later. Some, however, attempt to be more accurate with emotional expression over IM. Real time reactions such as (chortle) (snort) (guffaw) or (eye- roll) are becoming more popular. Also there are certain standards that are being introduced into mainstream conversations including, '#' indicates the use of sarcasm in a statement and '*' which indicates a spelling mistake and/or grammatical error in the prior message, followed by a correction. Tens of millions of the consumer IM accounts in use are being used for business purposes by employees of companies and other organizations. In response to the demand for business- grade IM and the need to ensure security and legal compliance, a new type of instant messaging, called . Microsoft followed suit shortly thereafter with Microsoft Exchange Instant Messaging, later created a new platform called Microsoft Office Live Communications Server, and released Office Communications Server 2. October 2. 00. 7. Oracle Corporation has also jumped into the market recently with its Oracle Beehive unified collaboration software. As of 2. 01. 0, leading EIM platforms include IBM Lotus Sametime, Microsoft Office Communications Server, Jabber XCP and Cisco Unified Presence.
