| E-business
A business with no online presence is a 'bricks-and-mortar' organization. At the opposite extreme, a few 'virtual' businesses exist only online. But most businesses are 'clicks-and-mortar' - they have some part of their business on the web, but also physical premises. The phrase 'e-commerce' refers to the part of e-business related to buying and selling. Retailers set up an electronic storefront (BrE shop front) and shoppers place items they want to buy in an electronic cart (BrE trolley). When the shopper is ready, they go to the 'checkout' where their payment is processed. For customers, key issues include: Fraud (the safety of online payment systems). Merchandise delivery and returns. The difficulty of speaking directly to a customer services representative rather than getting an automated response. For companies, key issues include: The protection of intellectual property (piracy). Website costs and maintenance. Measuring the effectiveness of the website (click-through rates for ads, traffic counts, conversion rates to show percentage of visitors who make a purchase). In terms of the technology involved, e-commerce is a good example of the role of dedicated (reserved for a specific use) servers: A database server stores customer data and product information in tables, An application server is responsible for calculations and program logic; it retrieves data from the database server and feeds it to the web server. , A web server is responsible for the interface and graphics; it presents the web page to the user. A browser on the user's computer allows the customer to interact with the company's web server. Exercises 1 Fill in the missing letters.
