Transcript of Digital Revolution
Digital Revolution? It began after World War II and is still the current age. It was the transition from analog electronic and mechanical devices to the digital technology still available to this day. It is an era that is on-going and is also known as the Third Industrial Age. Why did the Digital Revolution occur? The main reason to why the Digital Revolution happened was because people want more knowledge, power and control; people wanted faster communication, an increase of speed in certain operations, more reliable machines and a larger field of entertainment. As well as that, medicine and robotics sky-rocketed with the current technology such as X-ray, MRI, robotic surgery and bio-robotic limbs. How has it affected daily life? The Digital Revolution has had an immense effect on daily life in many ways; it made many jobs and actions easier. Sharing things became a lot faster, mobile phones, computers and again the internet made communication immensely faster with social networking sites such as Facebook and Twitter.
Gaining access of knowledge became easier and everything started to be more efficient such as medicine and the development of robotics. so far it left us with a fully computerized age; with the internet, almost everything is public; news, ideas, pictures, videos, etc... it has made people more aware of the happenings around the world and it has helped the creation of many other inventions.
However, the downside of all this that people have been replaced by robots, computers and other technology, accompanying the Digital Revolution. Global communication may have been increased, but communication with physical contact has been depleted majorly. This is because of the addiction caused by the digital technology. The Internet Charles Babbage In 1822, Charles Babbage began developing the Difference Engine, considered to be the first automatic computing engine that was capable of computing several sets of numbers and making a hard copies of the results. However, because of the lack of funding he was never able to finish a complete, working version of this machine. In June of 1991, the London Science Museum completed the Difference Engine MK2, 200 years after Babbage's birth and later completed the printing mechanism in 2000.
Later, in 1837 Charles Babbage proposed the first general computer; the Analytical Engine. The Analytical Engine contained an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory and is the first general-purpose computer idea. However, also because of funding issues this computer was never built while Charles Babbage was alive. In 1910, Henry Babbage, Charles Babbage's youngest son was able to complete part of this machine and was able to answer basic calculations. Conclusion The Digital Revolution is a continuous happening, as it is still going to this day. I think its main achievement so far is the increase in speed and quality of communication. As never before has there been such a connection on a global scale; you could be sitting in your lounge and at the same time bare witness to a live event, hundreds of miles away.
It has also led to the creation of hundreds of machines which we still use today e.g. TV, computer and phone. Because of it, there has been a great leap in almost every section in science such as an increase in quality and knowledge about surgery with robotics.
Science fiction has become a daily reality and the 'future' has become the present. Quiz 1. How large is the Internet?
2. Who created the first Computer?
3. In what year was the Transistor invented?
4. What do you think is the greatest impact of the Digital Revolution? Why?
5. What are the downfalls of this revolution? Why? The Digital Revolution The Transistor was invented in 1947. It is considered the most active section in practically all modern electronics and led to the development of advanced digital computers. Later this creation led to the founding of the worldwide web. The computer became a more common machine and by the end of the decade, being able to use one became a major part and need for many jobs. The first cellphone was also introduced during this decade. The World Wide Web had been introduced and by 1996 the Internet became a normal part of most business operations. By the end of the 1990s, the Internet became a part of everyday life for almost half of the American population. By now, the Digital Revolution had begun to spread all over the whole world; mobile phones were commonly seen, the number of Internet users continued to climb and the television started to change from using analog to digital signals. Now, today, at this very moment, the Internet is used every day every hour, every second by hundreds of thousands of people. Mobile communication has also become very important, as nearly 70 percent of the world's population owns a mobile phone. Today's tablets are said to take over all personal computers by 2015 and surpass them with the use of the Internet and the promise of Cloud computing services. Teens spend 31 hours online every week; 3.5 on IM, 2 hours on pornography, 35 minutes on weight loss, 2 hours on YouTube, more than an hour on cosmetic surgery, 1.5 hours on family plannings and pregnancy sites and only 4 hours on homework. Everybody knows that the internet is immensely large. But how large exactly?
Google estimates that it is about 5 million terabytes of data, which is the same as 5 billion gigabytes, which is the same as 5 TRILLION megabytes.
The human brain is said to be able to hold 1-10 terabytes.
Using an estimate of 5 terabyte per
human brain. It would take a million
human brains to store the internet! The Internet Population The Size How it's used The current amount of internet users is around 2.2 billion, in 2002 it was over 600 million - that's over a 367% increase in a decade.
98.7% of Iceland's population use the internet - highest in the world - America has 76.2%, China at 34% and North Korea - with the lowest - at 0%. Spammers Up to 40% of all accounts and up to 8% of all messages from social media sites are made by spammers Websites The first website and web server was launched on August 6, 1991. It was made by physicist, Tim Berners-Lee, the address was info.cean.ch. - Google receives over 100 billion searches each month, that's almost 40,000 searches per second.
- The founders of Google, Larry Page & Sergey Brin, own 16% of the company.
- Google+ was launched in 2011 and now has 250 million registered users.
- Google Chrome commands 1/3 of all world-wide usage of Web browsers. How did the Internet contribute to the Digital Revolution? The internet is a major part of the Digital revolution; once it was invented it made connecting with people better and faster, online gaming possible, getting knowledge easier, sharing of files e.g. photos, documents and music became possible. Not only this, but you can now put things on the internet, such as pictures, blogs and websites, for either the public or specified people.
The Internet made work a lot easier too; people can now work in a different country to their company and send their work or research via the internet and through video-conferencing. Furthermore, getting information for a certain report or concept became a lot easier with websites such as Wikipedia and YouTube. Information gets around faster through news websites and social networking sites. Also, important ideas, events and news is now accessible by a lot more people.
