It receives input data and instructions, processes the data according to the instructions, and produces output results. An information system also meets daily transaction needs, supports operations, and provides managerial and strategic support through reports to external stakeholders. The purpose of an information system is to support business functions like finance, accounting, operations, marketing, and human resources to achieve organizational goals.

2. What Is Information System?
According to O’Brien (2005, p5)
Information systems are a combination of each unit managed by people, hardware,
software, computer networks and data communication networks, and databases that
collect, change, and disseminate information about which forms of organization.
According to Gordon B. Davis (1991 : 91)
Information system is a system that receives data input and instructions, processes
the data in accordance with the instructions and releases the results.
According to Leitch Rosess (2005 : 11)
Information system is a system within an organization that meets the needs of
daily transaction processing, supports operations, is managerial and strategic activities of
an organization and provides certain external parties with the necessary reports.
The usefulness of the information system according to experts;
According to O’Brien (2005, p5)
Supporting the functions of the business area to achieve goals that include the
financial, accounting, operational, marketing, and human resources.
According to Krismiaji (2002 : 12)
Provides information to help management decision making
According to Kertahadi (2007)
Provide information in planning, organizing, and operating a company that serves
organizational synergy in the process of controlling decision making.
Why did I choose and what will I do with this information system later?
Why did I choose this because, I liked learning computers since I was a child,
when I was in high school I liked coding letters, wanted to try new things and get out of
my comfort zone. Later this information system will be useful for my life, and I will
continue to learn and give my knowledge to others, with my aspirations to become a
Lecturer.
So in my opinion the information system is, a component consisting of people,
information technology, and work procedures that process, store, analyze, and
disseminate information to achieve a goal.
