Internet history, Technology and Security (Week 3)

Week 3history:the Web makes it easy-to-use

Welcome to Week 3! This is our fourth and final week of history where we make the connection from those early innovations of the modern Inter NET we is using for the This class. Up next we move to looking at what the Internet works on the inside.

The Early world-wide-webgetting to the Web

Now it is time to leap into the Atlantic to CERN, a place where physicists from all over the world visit, live and work together. Here's a photo of the first band---the DooWop band, they sang the 50 's, but it's interesting that the content is about particles, the Internet, and modems!

The author also sang with a physicist (interesting life) named Steven Goldfarb.
The following section begins with Robert Cario Robert Cailliau, who is one of the inventors of the World Wide Web.

Robert Cailliau-co-inventor of the Web

Robert Cailliau is one of the co-inventors of the World Wide Web. Kallio was born in Belgium and graduated from university in 1969 with a master's degree in computer, information and control engineering from the University of Michigan two years later, majoring in electrical engineering and mechanical engineering. In December 1974, he began working as a researcher at CERN's Synchrotron (PS) division, where he worked on accelerator control systems. 1990 and Berners-Lee co-founded the World Wide Web.

At first, the network was not considered for use outside academia until 94 (the year it was called the network year) and business began to reach the network. There is a browser called NCSA Mosaic, or simply Mosaic, the first web browser in internet history to be universally used and able to display images. It was published by the NCSA organization of the University of Illinois at Urbana-Champaign in 1993 and formally terminated development and support on January 7, 1997. Popular at the time of popular outbursts. It runs on Unix and has a good graphical interaction interface. The emergence of Mosaic is one of the spark that ignited the late internet craze.

But the Mosaic browser has a drawback: in mosaic, there is only one window, and each click replaces the contents of the window, which is inefficient for the user. So began to make a browser macwww, is the first Macintosh Web browser.

A Search Engine for Physics articlesthe Web becomes Content

The teacher talked about his liking for HTML, compared to the HTML5 now better. Cailliau thought HTML was not elegant but very powerful, and he thought Mosaic's design was illogical, for example, every picture had to pop up on the same screen. The Network (1995) was very slow, and the user interface was usually a lot of text, and when you clicked on a picture, it entered a new interface and displayed the image. With the development of technology, network and computer are getting faster and more and more unreasonable.

Paul kunz-the First Web Server in America

Paul Kunz had no intention of creating the first search engine. SLAC's database is widely used, but access is difficult because it requires everyone to have an account on the mainframe, but for many people the mainframe is unfamiliar. Paul Kunz invented a method that is now called instant Messaging, and can query the database without logging on, which improves access to the database. Then people add an e-mail interface so that you can send a query by e-mail that you want to the database, and you can get your reply from the database. (This is a bit like the literature of our library is delivered via email) Paul Kunz joined Cern,tim Berners-lee in 1991 to show him a Web presentation that at first was not interested in querying the database of the Help system, But is it possible to combine anonymous queries? So he used the C language to write the software to get the user's query and convert it into a database query (because the database's query statements cannot be changed). One months later, a symposium on high-Energy and Nuclear Physics computing was held in southern France, and Tim Berners-lee a long, boring speech ... But he was connected to the slack network server and made a query, just click on the query. At that time caused a sensation at the venue. With an image of the saying: the venue has 20 people to 200 people interested, now the 200 people go home, if they each told 10 people, then within a week, the interest in the network will increase to 2000 people. So this is a big turning point. And this is a win-win situation, how to say? For the user, you can see what you want to see more quickly and at a lower price; for airlines, this is just the software that runs on the machine, and it costs a lot less.

Making the Web Available to allbuilding Mosaic

If there is no World Wide Web and no content, how do we know that the World Wide Web is a good way to browse information? Paul Kunz provides good content. In 1996 (three years after the birth of the Internet), the web was not really popular. At the time, Gopher was a very well-known information lookup system on the Internet, which organized files on the Internet into some sort of index, easily bringing users from one place on the internet to another. Before the advent of WWW, Gopher is the most important information retrieval tool on the Internet, and the Gopher site is also the most important site, using the TCP70 port. But after the advent of WWW, Gopher lost its former glory.
What does Steve Jobs have to do with Apple and the World Wide Web? In fact, he was expelled from Apple and created the next company, creating the Macintosh operating system. From a historical point of view, Steve Jobs has played a role in the formation of the Internet.
In the actual 90 's, computer technology and display capabilities quickly improved, in such an environment, NCSA built an open-source web browser that can run on Mac, Windows and UNIX systems.
