SUB-TOPIC 1:
Definition of World Wide Web
The World Wide Web (“www” or simply the “Web”) is a global information medium which users can read and write via computers connected to the Internet.
The term is often mistakenly used as a synonym for the Internet itself, but the Web is a service that operates over the Internet, just as e-mail also does. It is a system of interlinked hypertext documents accessed through the internet, by an application called a browser.
It is a network service used in accessing, manipulating, and downloading a very large set of interlinked hypertext document and other files located on computers connected through the internet.
The World Wide Web can also be defined as a system of interconnection of several computers all over the world; forming a web-like networked structure.
Technically it is the interconnection of internet servers that support specially formatted documents in HTML (Hypertext Markup Language)
Some notable application used to access the World Wide Web are:
- Firefox,
- Internet explorer,
- Google Chrome,
- Netscape navigator, etc.
EVALUATION:
1. Define the term ‘World Wide Web’
2. What is HTML?
SUB-TOPIC 2:
Brief History of World Wide Web
The development of the web began in 1989 by British engineer and computer scientist Sir Tim Berners-Lee and his colleague at the centre for European Organisation for Nuclear Research in Geneva. Using concepts from his earlier hypertext systems like ENQUIRE, the team developed a protocol, Hypertext Transfer Protocol (HTTP), which standardized communication between the servers and clients. Their text-based web browser was released to the general public in 1992. The web gained rapid acceptance with the creation of a web browser called mosaic, developed in the USA by Marc Andreessen, Mosaic’s graphical user interface allowed the web to become, by far, the most popular Internet Protocol. Today, the World Wide Web has millions of active users.Presently, Sir Tim Berners-Lee is the Director of the World Wide Web Consortium (W3C).
Some Contributions of Nigerians to the Internet
The advent of the World Wide Web has turned the world into a global village, thereby making information and communications development universal. Nigerians have a share of their contribution to the World Wide Web;
1. Seun Osewa: Seun Osewa is the founder of www.nairaland.com (Nigerians Web Forum). As at 2011, it was tagged the Nigerian’s top ranked online community having about 650,000 user accounts with about 30,000 users logging on in a month.
2. Emeka Okoye: Emeka Okoye designed the first banking website in Nigeria with IBTC Merchant bank, at the launch of Nigeria Equity Fund in December 1996.
He created the Internet banking application, which IBTC used for their online banking in 1997.
3. Iyinoluwa Aboyeji: Is a Nigerian living in Canada is developing a new web start up that aims to revolutionise how people use the web to learn.
He is 19 years old and has been living and studying in Nigeria in the last 3 years. He founded the Bookneto.
4. Others are Philip Emeagwali and Gilbert Chigozie (palchigo)
These contributions have made the World Wide Web more accessible, easier to navigate and user-friendly. Therefore, Nigerians deserve accolades for these pioneering efforts in ICT.
1. According to some sources, Seun Osewa created Nairaland.com in response to a lack of adequate online resources for Nigerians. He was motivated by a desire to foster community and conversation among Nigerian internet users, as well as provide a platform for sharing news, views, and information about the country.
2. Emeka Okoye’s work on Internet banking has had a significant impact on the Nigerian economy, facilitating more efficient and convenient transactions for businesses and individuals alike. Many other financial institutions have since adopted similar systems, helping to modernize the country’s banking sector and drive economic growth.
3. Compared to other platforms for learning online, Iyinoluwa Aboyeji’s web start-up aims to be more intuitive and user-friendly. It provides a personalized learning experience that adapts to each individual user’s needs and preferences, incorporating tools like adaptive quizzing and automated grading.
4. Philip Emeagwali is widely regarded as one of the pioneers of modern computer science, having played a key role in developing several important techniques and algorithms. His work has had a significant impact on the development of the Internet, helping to facilitate communication and collaboration around the world.
5. There is no doubt that Nigerians will continue to make significant contributions to the Internet in the future. Some possible areas of focus include new web technologies and platforms, improved security and privacy measures, and advances in artificial intelligence and machine learning. Additionally, with the growing presence of African startups in the global tech industry, there is potential for Nigerians to play a leading role in developing innovative solutions that address local needs.
In conclusion, there is no doubt that Nigerians have contributed significantly to the Internet and we can only expect more great things from them in the future.
