Ecommerce is the buying and selling of goods and services over the internet.
E-business includes ecommerce along with all activities related to internal and external business operations, such as servicing customer accounts, collaborating with partners, and exchanging real-time information.
E-business has many advantages, included expanding global reach, opening new markets, reducing costs, improving operations, and improving effectiveness.
(You should be able to define ebusiness and understand that it's not just ecommerce. You should be able to recognize the importance of how ebusiness tools revolutionized back-office processes (e.g., collaboration) and B2B ecommerce in addition to the B2C ecommerce. You should get the idea of Fig. 3.24, although you need not memorize all nine business models.)
The web has three key stages of evolution: Web 1.0, Web 2.0, and Web 3.0.
Web 1.0 refers to the World Wide Web during its first few years of operation between 1991 and 2003.
Web 2.0 is the next generation of internet use - a more mature, distinctive communications platform characterized by new qualities such as collaboration, sharing, and free.
Web 3.0 is based on "intelligent" web applications
using natural language processing, machine-based learning and reasoning, and intelligent applications.
(You should be able to describe the differences
between Web
1.0, Web 2.0, and Web 3.0. Specifically, you should understand the benefits that came with each evolutionary stage. For example, you should know that Web 1.0 extended
to reach of many businesses to global markets, and Web 3.0 is more about relationships between intelligent "things.")
