today we watch the short video about technology revolution
http://www.youtube.com/watch?v=-4CV05HyAbMtechnology really help in improve the way that knowledge is stored, created and shared
in the past:
we only find knowledge from books, magazines and newspaper,
however, it is quite time consuming that we need to find the book and then borrow or buy a copy;
it is also space-demanding in having a book;
it is inconvinent to share the knowledge with friends;
and not everyone can have the chance to create knowledge and share to publice
however, nowadays is a technolgy century:
most of the knowledge is post to the internat,
it really saves the space to store the book and save paper;
and all of us have the chance and right to have a look,
or maybe get a soft copy;
people can create the knowledge together such as wikipedia and share with others;
if there is any incorrect information, we can correct it through internat easily
