Quiz Answers
1.
Hosted applications tend to be less work up front and easier to maintain but offer
less flexibility than applications you install.
2.
Applications that make changes to the file system, either because they store their
data in files or because they allow users to upload files, generally require you to
change the file permissions for specific directories when you install them.
3.
Each application has its own table prefix to prevent naming conflicts when several
applications use the same database. For example, several applications might have
their own table called “users.” Adding an application-specific prefix to it will pre-
vent conflicts.
