Features and Functions of Information systems by Erin Kerr

Data

You need to input data into the system, before it is handled and output information that is useful, to the company. It then can be given out by different parts of the organisation and be obtained from outside the company. EK

People

Employees need to have right skills, to be able to the get best of the information system. EK

Hardware

Hardware must be able to run software and handle large amouny of data, that will be getting put onto the system. Also, it should be able to search through the computer system and find data. EK

Software

The software that is installed onto the computer must be able to make the information that the organisation needs, using it's features and functionally it has. And also, all staff need to have right training, in order to use it correctly. EK

Telecommunications

Often, information output will be needed in multiple locations, for it to function properly there must be a telecommunications infrastructure so that the data can flow to where it is needed. DF

Input

Input is a form of communication that the information system will use to process data and information going into the the system. DF

Storage

To properly organize data, you must have an efficient storage system. With the dawn of the digital age, it is fast becoming the standard to store data electronically using servers or cloud storage as it presents back-up and validity advantages. DF

Processing

It is often helpful to ensure that you use the proper procedures and do not excessively manipulate data that is being stored. There are many companies who might use manipulation to appear successful by removing one particular aspect. DF

Control and feedback loops

2015-05-13 06:35:01 UTC

A feedback loop is a powerful tool for developing a control system. Feedback loops consider the system output and enables the system to adjust its performance to meet the desired output response.

Control is the ability to have an influence on events, in this case being the feedback loops development and creating standards at which it will tailor its desired output response to. TC

Closed and Open systems

2015-05-13 06:36:22 UTC

Open systems are computer systems that provide unrestricted access by people and/or other computers. For example, a collaborative site on which anyone can upload and edit their work collectively.

Closed systems are the opposite of above, generally being highly privatised and restricted to protect important data (such as money) from being forged or manipulated maliciously. TC

Output

2015-05-13 06:53:32 UTC

Output is data generated by the information system on any level, for instance a basic instance of software output is a calculator program that produces the result of 2+2. Furthermore, output can also be considered as any data collected through the use of an information system, for example, after the use of cash flow forecasting, the monetary statistics discovered at the end are considered an output.
