Blackberry history and messenger

| 2 Nisan 2009 Perşembe

Blackberry history / The BlackBerry is a wireless handheld device introduced in 1999 as a two-way pager. In 2002, the more commonly known smartphone BlackBerry was released, which supports push e-mail, mobile telephone, text messaging, internet faxing, web browsing and other wireless information services as well as a multi-touch interface.

BlackBerry Messenger

Newer BlackBerry devices use the proprietary Blackberry Messenger software for sending and receiving text messages via Blackberry PIN.

Third-party software available for use on BlackBerry devices includes full-featured database management systems which can be used to support customer relationship management clients and other applications that must manage large volumes of potentially complex data.[8]

BlackBerry Messenger (abbreviated BBM) is a proprietary Instant Messenger application included on newer model BlackBerry devices. It was developed by Research in Motion. Messages sent via Blackberry Messenger are sent over the Blackberry PIN system; thus, communication is only possible between two Blackberry devices. Exchanging messages is also possible through obtaining discussion or chat rooms, which multiple blackberry devices are accessible to communicate. In addition to offering text-based Instant Messages, Blackberry Messenger allows users to send pictures and other files over the Blackberry network.

Instant messaging (IM) is a form of real-time communication between two or more people based on typed text. The text is conveyed via devices connected over a network such as the Internet.


Instant messaging (IM) are technologies that create the possibility of real-time text-based communication between two or more participants over the internet or some form of internal network/intranet. It is important to understand that what separates chat and instant messaging from technologies such as e-mail is the perceived synchronicity of the communication by the user - Chat happens in real-time. Some systems allow the sending of messages to people not currently logged on (offline messages), thus removing much of the difference between Instant Messaging and e-mail.

IM allows effective and efficient communication, featuring immediate receipt of acknowledgment or reply. In certain cases Instant Messaging involves additional features, which make it even more popular, i.e. to see the other party, e.g. by using web-cams, or to talk directly for free over the Internet.

It is possible to save a conversation for later reference. Instant messages are typically logged in a local message history which closes the gap to the persistent nature of e-mails and facilitates quick exchange of information like URLs or document snippets (which can be unwieldy when communicated via telephone).
