Java adds functionality to business applications and can handle transactions and a wide variety of actions on a client computer. This relieves an otherwise busy server-side program from handling thousands of transactions simultaneously. Once downloaded however, embedded Java code can run on a client’s computer and cause damage, run a Trojan horse, or turn the computer into a zombie.
To counter this threat, the Java sandbox security model was developed. The Java sandbox confines Java applet actions to a set of rules defined by the security model.
These rules apply to all untrusted Java applets. Untrusted Java applets are those that have not been established as secure. When Java applets are run within the constraints of the sandbox, they do not have full access to the client computer.

Answer 25

Without a clear understanding of a firm's target audience, it is difficult to develop a successful e-commerce presence. There are two primary questions: who is the target audience and where can they best be reached? A target audience can be described in several ways: demographics, behavior patterns (lifestyle), current consumption patterns (online vs. offline purchasing), digital usage patterns, content creation preferences (blogs, social networks, sites like Pinterest), and buyer personas (profiles of your customer). Understanding the demographics of the firm's target audience is usually the first step. Demographic information includes age, income, gender, and location.
