Question 3.
What are the types of convergence. Explain them.
What are the types of convergence. Explain them.
Answer:
Digital Convergence
It is the collection of underlying digital technology components and features such as voice, texts, videos, pictures, broadcasts, presentations, streaming media, global connectivity and personalised services.
It refers to the convergence of four industries into one Conglomerate (Combination of two or more enterprises)— ITTCE (Information Technology, Telecommunication, Consumer Electronics and Entertainment).
Messaging Convergence
It means integrating SMS with voice, e.g. Voice SMS (voice instead of text) and SpinVox (voice to text). Due to change in communication, the main problem that arises for operators is to adjust all aspects of their business, including their mobile, television and Internet networks that are converging and progressing day-by-day. In addition, today’s wide variety of messaging options, including SMS, MMS, E-mail, Instant messaging and Video sharing are creating challenges for users and operators to manage it.
Media Convergence
It involves the interlocking of computing and IT companies, telecommunication networks and content providers from the publishing world of newspapers, magazines, music, radio, television, films and entertainment softwares. It brings together the “3Cs” and is the direct convergence of the digitisation of media content and the popularisation of the Internet.
Device Convergence
It means the trend in network device architecture to support different networking paradigms in single system.
e.g. communication and imaging technologies on a mobile device designed to make calls and take pictures. Both are unrelated technologies that converge on a single device.

Question 4.
Define Voice over Internet Protocol (VoIP). Also explain its advantages of using VoIP
Define Voice over Internet Protocol (VoIP). Also explain its advantages of using VoIP
Answer:
VoIP is an IP telephony term for a set of facilities used to manage the delivery of voice information over Internet. It enables a user to make cheap telephone calls over a broadband Internet connection, instead of using a regular telephone service. A major advantage ot VoIP is that it avoids the tolls charged by ordinary telephone service.
A user can make a call locally or in other parts of (JS or Canada, or anywhere else in the world, eliminating long distance fees by using a VoIP service. The concept of VoIP is used in wireless LAN networks and sometimes referred to as wVoIP, VoFi, VoWi-Fi and Wi-Fi VoIP.
