Q & A

Question 1: What was the significance of ARPANET in the development of the internet?

ARPANET, founded in 1969 by ARPA, was the first packet-switching network and served as the precursor to the modern internet. It connected the first four nodes, including UCLA, UC Santa Barbara, Stanford, and the University of Utah, laying the foundation for network communication.

Question 2: When was TCP/IP fully specified and why is it important?

The full specification of the TCP/IP protocol was created in 1981. It is crucial because TCP/IP established a standard for data transmission, allowing different networks to communicate with each other and forming the backbone of the modern internet.

Question 3: What was the first domain ever registered?

The first domain ever registered was 'symbolics.com' in 1985. This marked the beginning of the domain name system (DNS), which plays a vital role in identifying and locating computers on the internet.

Question 4: Who invented the World Wide Web (WWW) and when?

The World Wide Web (WWW) was invented by Tim Berners-Lee in 1989. He also initiated the development of HTTP, which made it possible to access and link documents over the internet, revolutionizing how information is shared.

Question 5: How did the introduction of the first search engines impact the internet?

The first search engine, Archie, was developed in 1990, followed by others like AltaVista and Google. These search engines made it easier to find information on the vast and growing network of the internet, significantly improving user accessibility and usability.

Question 6: What role did social media play in the evolution of the internet?

Social media platforms like Facebook (2004), YouTube (2005), and Twitter (2006) transformed the internet into a space for social interaction, content sharing, and community building, significantly expanding its reach and impact on daily life.

Question 7: How did the dot-com bubble burst in 2000 affect the internet?

The dot-com bubble burst in 2000 led to a market crash due to the overvaluation of internet companies. Despite the downturn, it resulted in the survival of more sustainable and innovative internet businesses, paving the way for the current digital economy.

Question 8: How has internet accessibility changed from 1995 to today?

In 1995, only 0.4% of the global population had internet connectivity. As of today, at least 62% of the global population has internet access, highlighting the rapid expansion and integration of the internet into everyday life.

Question 9: What advancements were made in internet security in 2014?

In 2014, Google and the browser community enforced HTTPS to make internet connections more secure. This enhanced data privacy and security, protecting users from eavesdropping and cyber-attacks while they browse the web.

Question 10: How did the COVID-19 pandemic affect internet usage?

The COVID-19 pandemic in 2020 significantly increased internet usage due to the rise of remote working and online activities. This made the internet more important than ever, as it became a primary medium for communication, work, and entertainment.
