LIS 2600 Unit7 Internet and WWW Technologies reading notes

1, How Internet Infrastructure work
The content is similar with what we have learned in the class.
URL, domain name, web servers, the topology of internet work.

2, According to the article, library vendors have two choices. They can continue to maintain large systems that use proprietary methods of interoperability and promise tight integration of services for their customers.
I think this approach is difficult to realize for some too old system, especially in developing countries.
My undergraduate university used to operate a small library system which is designed by China in 1970s. However, with the development of library holdings, catalog records and electronic database. The original library system is not applied to the current the conditions any more no matter how hard that the library vendor work on. The university library decided to change its library system.
However, changing a library system is so complicated, tremendous data have to transfer to another new library system, which is a pains-taking job. Besides, new models is strange for librarians and patrons. The effects of the new library system have to be evaluated carefully.

3,Talks Sergey Brin and Larry Page on Google
The global map of Google is amazing.
I am interested in listening to what they say! It is useful and indeed relaxing!
