Name 4 system software categories2/19/2023 Today, most software is purchased and directly downloaded over the internet. In the 1980s, software began to be sold on floppy disks, and later on CDs and DVDs. Other types of software include programming software, which provides the programming tools software developers need middleware, which sits between system software and applications and driver software, which operates computer devices and peripherals.Įarly software was written for specific computers and sold with the hardware it ran on. System software is designed to run a computer's hardware and provides a platform for applications to run on top of. An application is software that fulfills a specific need or performs tasks. The two main categories of software are application software and system software. It can be thought of as the variable part of a computer, while hardware is the invariable part. Software is a generic term used to refer to applications, scripts and programs that run on a device. It is the opposite of hardware, which describes the physical aspects of a computer. Further ClassificationĪn information system can be categorized based upon activity into strategic planning system, tactical information system and operational information system.Software is a set of instructions, data or programs used to operate computers and execute specific tasks. Decision support system provides information to manager facilitating specific issue related solution. Management information system provides information to manager facilitating the routine decision-making process. Management support systems are essentially categorized as management information system, decision support system, expert system and accounting information system.

In any given organization information system can be classified based on the usage of the information. During output stage, data is presented in structured format and reports. During input stage data instructions are fed to the systems which during process stage are worked upon by software programs and other queries. Information processing consists of input data process, data storage, output and control. People consist of device operators, network administrators and system specialist. Network consists of hubs, communication media and network devices. Database consists of data organized in the required structure. Software consists of various programs and procedures. Hardware consists of input/output device, processor, operating system and media devices. These five components integrate to perform input, process, output, feedback and control. Components of information systemsĪn information system is essentially made up of five components hardware, software, database, network and people. An information system is integrated and co-ordinate network of components, which combine together to convert data into information.
