5. Information Systems
• System: A set of Components that work together to achieve a
common Goal
• Subsystem: One part of a system where the products of more
than one system are combined to reach an ultimate goal
• Closed System: Stand-alone system that has no contact with
other systems
• Open System: System that interfaces with other systems

8. Why Study IS?
• Information Systems Careers
• Systems analyst, specialist in enterprise resource planning (ERP), database
administrator, telecommunications specialist, consulting, etc.
• Knowledge workers are typically professionals who are relatively well educated
and who create, modify, and/or synthesize knowledge as a fundamental part of
their jobs.
• Employers seek computer-literate professionals who know how to use
information technology.

10. Information System
An IS using computer technology to carry out some or all of its
planned tasks.
•Hardware- these are the devices like the monitor, processor,
printer and keyboard, all of which work together to accept,
process, show data and information.
•Software- are the programs that allow the hardware to process
the data.
•Databases- are the gathering of associated files or tables
containing related data.
•Networks- are a connecting system that allows diverse
computers to distribute resources.
•Procedures- are the commands for combining the components
above to process information and produce the preferred output.

11. Examples
1- People in organizations use information systems to process sales
transactions, manage loan applications, or help financial analysts
decide
where, when, and how to invest.
2-Product managers also use them to help decide where, when, and
how to market their products and related services, and production managers
use them to help decide when and how to manufacture products.
3-Information systems also enable us to get cash from ATMs,
communicate by live video with people in other parts of the world, and buy
concert or airline tickets.
