What is an Information System?

9 Mar

Hi fellow bloggers,

Today I am here to talk about information systems as they have become massively important in the running of the world of business as technology keeps improving everyday.An information system is a set of interrelated components that collect, retrieve, process, store, and distribute information to support decision making and control in an organisation.

In recent years, society has become more reliant on information systems.
Information system itself bring the meaning of business application in the computer that manage their operations, compete in the marketplace, accounts and manage human resources.
5 key elements to information systems

Hardware-is the most obvious part of a computer-based information system. Hardware refers to the computers themselves, along with any and all peripherals, including servers, routers, monitors, printers and storage devices.

Software-Without software, the hardware wouldn’t be very useful. Software, is what tells the hardware how to function. It gathers, organizes and manipulates data and carries out instructions. Everything you do using a computer is done by the software.

Data/Information-Just as hardware cannot function without software, software cannot function without data. This is the information part of an information system, and whether that is statistical data, sets of instructions, lists of names or even graphics and animations, it is all key to a business information system.

People-are the most often overlooked and most important part of a based information system. It is people who design and operate the software, input the data, build the hardware and keep it running, write the procedures and it is ultimately people who determine the success or failure of an information system.

Procedures-It is commonly said that “procedures are to people what software is to hardware.” Procedures are the rules, descriptions and instructions for how things are done. In computer-based information systems, procedures are frequently covered in instruction or user manuals that describe how to use the hardware, software and data.
