Informatics is the interdisciplinary study of the design, application, and impact of information technology. It encompasses disciplines like artificial intelligence, cognitive science, and computer science. Information systems involve the use of hardware, software, and networks to collect, process, and distribute data within organizations. They provide important functions like communication, operations, decision-making, records keeping, and more. There are different types of information systems such as decision support systems, transaction processing systems, expert systems, management information systems, and others.

2. Informatics
 Informatics is the science of information.
 the application of information technology to the arts,
sciences, and professions.
 the interdisciplinary study of the design, application, use
and impact of information technology. The discipline of
informatics is based on the recognition that the design of
this technology is not solely a technical matter, but must
focus on the relationship between the technology and its
use in real-world settings.

3.  Informatics has many aspects, and encompasses a
number of existing academic disciplines - Artificial
Intelligence, Cognitive Science and Computer Science.
 Cognitive Science concerns the study of natural
systems;
 Computer Science concerns the analysis of computation,
and design of computing systems;
 Artificial Intelligence plays a connecting role, designing
systems which emulate those found in nature.

4. Information Systems
 is the study of complementary networks of
hardware and software that people and
organizations use to collect, filter, process, create
and distribute data.
 Information Systems encompasses a variety of
disciplines such as: the analysis and design of
systems, computer networking, information
security, database management and decision
support systems
 An information system (IS) refers to a collection of
multiple pieces of equipment involved in the
dissemination of information. Hardware, software,
computer system connections and information,
information system users, and the system’s
housing are all part of an IS.

5.  A Computer(-Based) Information System is
essentially an IS using computer technology to
carry out some or all of its planned tasks.
 The first four components (hardware, software,
database and network) make up what is known as
the information technology platform. Information
technology workers could then use these
components to create information systems that
watch over safety measures, risk and the
management of data. These actions are known as
information technology services

8. Information systems: This type of ICT system
is focused on managing data and information.
For examples: these are a sports club
membership system or a supermarket stock
system.
Control systems: These ICT systems
are mostly part to control machines. They
use input, process and output, but the output
may be moving a robot arm to weld a car
chassis rather than information.
Communications systems: The output of
these ICT systems is the successful transport
of data from one place to another.
