The Internet - Yesterday, Today, and Tomorrow


Wikipedia says that the Internet is a global system of interconnected computer networks. What you see in the title image taken from The Opte Project, is just a fragment of a much larger internet map. Obviously, it is impossible to map all computers connected to the internet. Thousands of them go down every day while new ones replace them. The fact remains -- internet is growing.
It is also virtually impossible to determine the "birthday" of the internet. A simple search on Google will give you plenty of different opinions: some say that it is over thirty years old while others argue it is more like twenty. And yet, for the purposes of this article, let's just say the internet was born on 6th of August 1991, when Tim Berners-Lee has introduced his idea of the World Wide Web at CERN laboratories in Switzerland. After all, to many casual users the whole complex structure of the internet is reduced to daily typing-in those three magic letters into their browsers -- WWW.
Let's go back and see what people thought of the internet before it was born. Interestingly enough, it seems that people cared about e-commerce more than they did about information sharing. The first video is from 1969 and it rather accurately describes the idea of e-commerce. Of course, the way it is visualized looks funny to us, but the concepts are accurate:

The second video is a bit more recent -- it's a news report from 1981 talking about this great new (still pre-internet) invention of reading the newspapers on your computer screen. This one is not a concept but rather a report on existing technology. Still, it serves as a great example of how fast everything evolved:
So what does the internet look like today? Well, you can take a look at the visualization again, but that doesn't help much, does it? How about some numbers then?
Asa Dotzler, the founder of Mozilla's Quality Assurance and Testing Program, did some very simplified calculations. He says:
The chart is a mash up of about 40 different data sources from usage, to market share, to installed base, for browsers, internet connected computers, and operating systems. Working through all that data, I was able to come up with something that I think approximates the Web's user growth and browser changes over the last 13 years.
Probably most "real" statisticians would dismiss these kind of calculations right away, but this chart does not become any less interesting because of that. So here it is for your judgment:
What does this chart tell us? Well, first of all, there are around 1.2 billion (almost 1.4 based on WolframAlpha) internet users world-wide. This is around 20% of the whole world's population. Also, it is rather interesting to note that while Firefox and other browsers were gaining popularity, it wasn't really at the expense of Internet Explorer. IE's usage simply slowed down, meaning that new internet users chose alternative browsers such as Firefox more often. However that's not what this article is about, so let's just leave it here.
In just under fifteen years the internet has become an integral part of our daily lives. As we have said before, nowadays the internet is (re)defining every aspect of our daily lives: form economy, to social life; from the way we do business, to the way we have fun. Most of us probably do not imagine going a day or whole week without internet access. To some of us it has become an actual addiction and there are even clinics that specialize in treating this disorder alongside with gaming and computer use addictions.
So what awaits us in the future? It's hard to predict, but there are some things that we are quite certain of. Obviously there will be an even bigger spread of internet-enabled consumer electronics. Having a tablet PC, PDA, or internet enabled phone is nothing new today, but what about internet enabled toasters and refrigerators? True, all this technology exists already, but it's not that wide-spread.
Technologies, enabling us to connect to the internet will evolve for sure. At the very least, existing technologies such as Wireless-N protocol and WiMax will become more popular.
And maybe, just maybe we will finally see a true smart-house: symbiosis of artificial intelligence and internet connectivity powering and controlling every single aspect of the house. Why maybe? Well, it's possible today, but the problem is that several kilometers of wiring is required to connect everything. So until we have wireless electricity or some other alternative, it remains just a "maybe"...

Did you know we can get a broadband internet signal almost anywhere on earth through the use of satellites? This shouldn't be too much of a surprise - after all, by now most of you have heard of people using mobile satellite phones to place calls from deserts, oceans, and mountaintops. It's not that much of a jump from a radio signal to an internet signal.

Due to the nature of broadband by satellite technology , it is not the best choice for someone simply surfing the net at home in a big city with several high-speed broadband internet service providers (ISPs). Broadband by satellite, however, is highly useful for people with no other internet options, living miles and miles from the nearest ISP. This article will describe the advantages and disadvantages of broadband by satellite.

Advantages of Broadband by Satellite

Location

First, the main advantage of broadband by satellite is that you can get a broadband internet signal anywhere on earth, no matter how far you are from the nearest Ethernet port of cable connection. This is useful for people who live in remote rural locations where the only internet option available is the agonizingly slow 56 Kbps dial-up telephone modem connection.

Mobility

Second, by its very nature, broadband by satellite is a wireless connection that allows considerable freedom of movement. This is particularly useful for maintaining an internet signal in mobile locations, such as while in moving vehicle like trains or in a ship at sea.

Disadvantages of Broadband by Satellite

Line of Sight

In order for a satellite dish to receive a broadband internet signal, it must have a free line of sight to the geostationary satellite in orbit. Obstacles such as buildings, trees, and even leaves can get the way of line-of-sight and block the signal, leaving you with no connection.

Weather

Although rain will not block a broadband by satellite signal, it will cause an interference known as "rain fade." Rain fade results in slower upload & download speeds and a patchy connection.

Connection Speed

When an internet signal has to travel 22,000 miles to a satellite in earth's orbit and back, a certain about of latency (the delay between requesting some data and getting a response) is unavoidable. The average latency for broadband by satellite is between 500 and 900 milliseconds-much worse than even a dial-up internet connection, where the latency is only 150 to 200 milliseconds. Although this slow data transfer speed is just fine for basic internet usage-email and web browsing-it is too slow for computer applications that require real-time internet access, such as internet gaming, videoconferencing, and VoIP (Voice over IP) telephone conversations.

Cost

Broadband by satellite costs considerably more than earth-based, wired technology like DSL or cable modems. On average, broadband by satellite costs two three times as much as from a land-based internet service provider. Finally, broadband by satellite equipment such as the satellite dish and satellite modem costs between $600 and $2000, considerably more than a cable or DSL modem, which usually cost less than $150.

Scholarship Search Secrets is a 35 page electronic book (eBook) about how to use popular Internet technologies like Google web search and RSS to find scholarships. Now in its fourth edition, reviewers have strong words for Scholarship Search Secrets:
Terry Klein, assistant director of financial aid at Wisconsin Indianhead Technical College, said, "The specific and practical instructions and use of current technology are perfect. I also love that it's very proactive and that it lets students know they can take responsibility for funding their education instead of relying on others."
Dover High School senior Richard Mondello said, "A must-have document for any student - high school or college. There are some fairly technical tools that can unlock the scholarship process. If you don't know how to use them, you're missing out. This eBook clearly explains them."
