Information Systems Management. What is an information system is any combination of information technology and people's activities that support operations, management and decision making.
With the helps of Information System, businesses are able to process and operate its daily works more accurate and easier. All data and information are stored in electronic database which is much safer and easier to be attached than traditional method. An Information System (IS) consists of five basic resources, namely:
1- People, which consists of IT specialists And End-users.
2- Hardware, which consists of all the physical aspects of an I S.
3- Software, which consists of System Software, Apps, and Utility software.
4- Data, which consists of all the knowledge and databases in the IS.
5- Networks, which consists of communication media and network support. What is the difference between information system and information technology? INFORMATION SYSTEMS
Vs.
INFORMATION TECHNOLOGY DATA, INFORMATION, KNOWLEDGE Data.
Would be the precepts a machine system gets about the world. It might be structured, or unstructured. Noisy or clean. Relevant or Irrelevant, and so on. Knowledge.
Would be an organised, historic, information about the world.
One might say that knowledge is a database of fact about the world. Information.
Would be some structured representation of data relevant to the machine system. How Systems Function. What Is A System?
Since a system is a subjective concept, there is no unanimously accepted definition of a system.
• A system is an organised assembly of components with special relationships between the components.
• The system does something, i.e. it exhibits a type of behaviour unique to the system or has a specific objective or purpose.
• Each component contributes specifically towards the behaviour of the system and is affected by being in the system. If a component is removed, it will change the system behaviour.
• Someone has identified the system as being of special interest. Elements Of A System:
1.Inputs And Outputs.
2.Processor.
3.Control.
4.Environment.
5.Feedback.
6.Boundaries And Interface. Information System Technologies Networks:
The networking and communications infrastructure has recently been considered to be a separate component of information systems, although in some cases this distinction can be regarded as a matter of personal opinion. There are definitely a number of specific decision and management issues associated with the network infrastructure. On the other hand, the network infrastructure also consists of hardware and software components, most of which share attributes with the mainstream information systems hardware and software mentioned above. Hardware:
The most easily visible component of an information system is the hardware. One can typically distinguish between the media used to store the information and the capital equipment used to read, write and store the media. Is The Internet The Global Information System?
The Internet provides a broad area of services to business and individual users and the World Wide Web (WWW) is its fastest-growing application. Because the WWW can reach any Internet-connected computer in the world, users typically call the Internet a global information system. Although the Internet and the global information system are closely related, they also have characteristics that distinguish each from the other. The purpose of this article is to identify the differences and address ways of building an Internet-based global information system. What is The Internet?
The origins of the Internet can be found in the early sixties, when the US Department of Defence sponsored a project to develop a telecommunications network that would survive a nuclear attack.
The Internet (or, more colloquially, the Net) consists of a huge and fast-growing number (hundreds of thousands) of interconnected networks linked together.
But the Internet is more than just a huge information resource. Its initial purpose was to act as a communications network and it fulfils that role well. It is the transport mechanism for electronic mail, the transfer of computer files, remote computer access and even allows for voice calls. Businesses quickly realised the potential of the multimedia-enabled Internet for marketing purposes. Of late, more and more business transactions are being conducted via the Internet: electronic commerce (e-commerce) is the latest revolution to be embraced by the Internet community.

IT deals with the technology involved in the systems themselves An information system is a system that gathers and transforms data in order to produce information for its end-users.
