Module 1 – Protocols

Voice over Internet Protocol (VoIP)

Website 1:

What is VoIP?VoIP’ or ‘Voice over Internet Protocol’ is a fairly new way of communicating using the Internet technology. Simply, it is a system where a person’s voice is converted into a digital signal when he/she is speaking into a normal telephone hand set, and converted back to a normal voice at the other end of the line.

Annotation: This website gives an easy definition about VoIP.

There is a ‘table of contents’ in this website which is easy to navigate to find out more about the technology.

The article listed above explains in simple terms how ‘Voice over Internet Protocols’ works, the equipment needed, the strengths and weaknesses of the technology.

It explains about how the ‘Internet Phone’ technology has revolutionized telephone communication all over the world. The articles in the website explain about how VoIP has helped in cost savings for telephone communications.

The explanation is easy to read and understand because it is written in a simple form which novice computer users can understand. The article explains about ‘packet switching’ and how efficient the technology is.

There are also a very easy to understand diagrams that explain how VoIP works.

It is a great website for people that want to learn the basics about VoIP. There is also a ‘Glossary’ page in the website.

The website is current and is written by the International Engineering Consortium (IEC). They are a non profit organisation who provides educational programs to universities in the electronics industry.

Summary & Evaluation: I chose to write about ‘Voice over Internet Protocol’ (VoIP) because I think that it should be an essential part of NET11. It is an important part of Internet communication via ‘IP’ which we should learn more about.
