first we have to differentiate between IT and IS.
Information
Technology (IT) is
all forms of technology (tool) used to create, store and use information.
Information Systems
(IS) is the combination of
technology (the “what”), people (the “who”) and process (the “how”) that
organization uses to produce and manage information.
Second Why
Should I Study Information Systems? becouse we are the most connected generation in history and we practice continuous computing. Also we are surrounded by a personal, movable information network and we can pull information from the Web and push ideas back to the Web.
Also we are Informed Users which is defined as a person knowledgeable about information
systems and information technology and tend to get more value from whatever technologies / systems we use.
Third, Computer-based
information systems are
information systems that use computer technology to perform some or all of
their intended tasks (Hardware, Software , Database , Network,
Procedures and People)
Hardware is a device such as a
processor, monitor, keyboard or printer.
Software is a program or collection of programs that enable hardware to process
data.
Database is a collection of related files or tables containing data.
Network is a connecting system (wireline or wireless) that permits different
computers to share resources.
Procedures are the set of instructions about how to combine the above components
in order to process information and generate the desired output.
People are those individuals who use the hardware and software, interface with
it, or uses its output.
Fourth, Types of Information Systems
which are IT components, IT services and
IT personnel that support an entire organization.
IT components (platform) consist of hardware, software, telecommunications and networks, and
wireless communications.
IT services consist of data management, managing security and risk, and systems
development.
IT personnel use IT components to
produce IT services.
Finaly, How Does IT Impact Organizations? IT
Affects Our Quality of Life, Robot Revolution on the Way and Improvements in
Healthcare.
