Lecture 2 Summary

Today, the lecture introduced the history of computer and internet.

The first part talked about the history of computer. Computer is process information. The Origen computer was used of mathematic calculation. The Second Word War, computer was use to calculate and it mainly used in military contents. With the developing of computer, it stared to broadly use in business areas. Computers were first commercially produced by IBM in the 1950s. The first generation of computers were large, unwieldy and expensive machines for military, government and corporate work but it quickly became apparent that computers would get smaller, quicker and less expensive at an exponential rate. In 1975, the first PC (personal computer) was released, however, the biggest problem is it didn't have a language - a set of terms by which the user could communicate with their computer. Bill Gates was the first people who writing a language called BASIC for the Altair. And then Microsoft/Bill Gates made a decision to promise an Operating System. GNU/Linux is a beautiful example of the idea of Open Source software development where a community comes together to work on a project for the sake of a job well done. Meanwhile, the computer hikers appear as well. These hikers are computer export; they create software and share it with each other.


The second part talked about the history of internet. The internet is a network of networks. These networks include servers, mainframes and personal computers and many other devices that use CMC (computer-mediated communications) technology, loosely interconnected by the telephone system and, more recently, broad-band cable and satellite services, to link people around the world into an information-sharing system. The idea of the Internet came from RAND Corporation in the 1960s. By applying game theory, RAND developed a scheme for a communication, command and control network that could survive a nuclear war because it had no central control, and could reform around communication services left intact. Web is one particular use of the Internet that emerged in the 1990s. Some of the early internet applications that were instrumental in defining the nature and use of the internet are as follows: Electronic mail (Email), File Transfer Protocol (FTP) and Internet Relay Chat (IRC).At the last part, a video simply illustrated how the internet work.
