2. Read Chap. 4 of the textbook. What is the Business-to-business model?
A2 : Business-to-business (or B2B for short) model is a marketing strategy which involves the transaction of goods or services between businesses, and the exchange of goods, services and information between companies. Business-to-business electronic commerce is companies buying from and selling to each other electronically, but it has evolved to include supply chain management.
3. Digital goods can be distributed over the Internet but physical goods have to be delivered logistically. What are digital goods? What are the differences between the two?
A3: "Digital goods " are a combination of signals, electronically represented as 0 and 1. As such they build a system of information which can express different contents, for example music, texts, pictures, numbers or algorithms. The existence of such immaterial content is not new, but rather the form in which it can be expressed now. So, a digital good is a result of the development of the information and communication technology. The new quality of this technology is that not only can the information be transformed into data, but it can also be sent through the world wide internet and it is a characteristic of these goods that they increase and don't decrease when they are passed on. What I want to say is that they double when reproduced which is normal in copying processed but in the case of digital goods they double without a loss in quality and they double to almost zero costs. One can say that through the new technologies the productivity in reproducing information could be raised dramatically supply is potentially infinite .
differences between physical goods and Digital goods :
- Digital goods can be distributed over the Internet but physical goods have to be delivered logistically.
- digital goods are intangible but physical goods are tangible .
- digital goods reproduced only to do copy file and almost zero costs and without a loss in quality but physical goods thereagainst.
4. Using RSS to track many blogs at one time.
What is the RSS feed that Google Reader takes in? List the URL of these RSS feeds.
A4: RSS stands for "Really Simple Syndication". It is a way to easily distribute a list of headlines, update notices, and sometimes content to a wide number of people. It is used by computer programs that organize those headlines and notices for easy reading.
RSS works by having the website author maintain a list of notifications on their website in a standard way. This list of notifications is called an "RSS Feed".
List the URL of these RSS feeds:
