(1) Knowledge Questions (know the answers, but do not submit.)
a) What is the difference and what is the relation between “IT infrastructure” and “IT
architecture”? Illustrate your answer in the case of an online travel agency.
The IT (or computing)
is a high-level map or plan of the information assets in an
organization. It integrates the entire organization’s business needs for information, the IT
infrastructure, and all computing applications. The IT (or computing)
of the implemented, physical facilities, IT components, IT services, and IT personnel that
support the entire organization by computing.
An organization is guided by its IT architecture to build and implement its information system.
The IT infrastructure is not the blueprint. It includes basic IT entities that support the IT
In the case of online travel agency, the IT infrastructure includes software (e.g., Windows XP),
hardware (e.g., server, PC), networks (e.g., wireless network), IT employees (e.g., programmer),
data management (e.g., a relational database system), security management (e.g., a combination
of firewall and antivirus software), and system development (e.g., a R&D team with software
and hardware support). The IT architecture integrates the IT infrastructure with other
components and is the blueprint for an airline company to build its information systems and
b) Understand the difference between: Data; information; knowledge; wisdom. Illustrate for
microelectronics facility design.
(See definitions in the textbook) In microelectronics facility design, the dimension of a machine
is an example of data item. The machine name, quantity, and its dimension together are an
example of information (data with specific meaning). The layout of a microelectronics facility is
