NOTES AND WORD DEFINITIONS
Information Technology (IT) The combination of hardware, software, and services people use
to manage, communicate, and share information.
Systems Analysis and Design A step-by-step process for developing high-quality information
systems.
Information System Combines technology, people, and data to provide support for business
functions.
Systems Analyst Member of the IT department who helps plan, develop, and maintain
information systems.
System A set of related components that produces specific results.
Mission-Critical System One that is vital to a company's operations.
Data It consists of basic facts that are a system's raw material.
Information Data that has been transformed into output that is valuable to users.
Hardware Consists of everything in the physical layer of the information system.
Moore's Law In 1965, Gordon Moore predicted that the number of transistors on an
integrated circuit chip would double every 24 months.
Software The programs that control the hardware and produce the desired information or
results.
System Software It manages the hardware components, which can include a single
computer or a global network.
Application Software It consists of programs that support day-to-day business functions and
provide users with the information they need.
Enterprise Applications They include order processing systems, payroll systems, and
company communications networks.
