Fully Eliminated the Language Barrier and Enable Ease of Communication Through This Application
IOSR Journal of Computer Engineering (IOSR-JCE) e-ISSN: 2278-0661, p- ISSN: 2278-8727Volume 16, Issue 2, Ver. XI (Mar-Apr. 2014), PP 113-119 www.iosrjournals.org Alltalk™- A Windows Phone Messenger with Cross Language Communication Shruti Shetye1, Akhil Abraham2, Royston Pinto3, Sonali Vaidya4 1(BE-IT Student, Information Technology, St. FrancisInstitute of Technology, India) 2(BE-IT Student, Information Technology, St. Francis Institute of Technology, India) 3(BE-IT Student, Information Technology, St. Francis Institute of Technology, India 4(Lecturer, Information Technology, St. Francis Institute of Technology, India) __________________________________________________________________________________ Abstract:In day to day life, messengers or chatting applications provide facility for instant messaging over the internet. Exchange of messages takes place in universally used languages like English, French, etc. where both the users know how to communicate in a common language. Thus chatting on mobile phones is a luxury when both the parties involved know a common language. Hence we have implemented ALLTALK™ which is a Windows 8 phone based chatting application which makes cross language communication possible using mobile programming and networking technology.This application will enable the communication between two persons irrespective of the language each user wishes to use individually. The various modes of communication available in this messenger are through text and voice. Due to the best processing power provided among the available smartphones and high battery life we choose to work on windows 8 platform. Thus we have successfully eliminated the language barrier and enable ease of communication through this application. Keywords: Cross Language communication, instant messenger, socket connection, translator,Windows phone app. -
Campus Networking Best Practices Session 5: Wireless

The standardisation based networks are IRC group chats and the XMPP instant and acceptance of protocols such as SMTP, IMAP, POP3, XMPP, messaging and multi-user conferencing network. and IRC has allowed to deploy servers for email and chat in a decentralised and interoperable fashion.

What this tutorial is about You surely know the internet service providers that allow you to rent a domain and use it to receive emails. If you have a computer running Debian which is connected to the internet permanently you can do that yourself. You do not even need to have a fixed IP address thanks to dynamic DNS services like dyndns.org. All you need is this document, a cup of tea and a little time. When you are done your server will be able to... receive and store emails for your users from other mail servers let your users retrieve the email through IMAP and POP3 even with SSL to encrypt to connection receive and forward ("relay") email for your users if they are authenticated offer a webmail interface to read emails in a web browser detect most spam emails and filter them out or tag them License/Copyright This tutorial book is copyrighted 2009 Christoph Haas (email@christophhaas.de).
