5 Components of Information Systems

The computer age introduced a new element to businesses, universities, and a multitude of other organizations: a set of components called the information system, which deals with collecting and organizing data and information. An information system is described as having five elements.

Computer hardware

This is the physical technology that works with information. Hardware can be as small as a smartphone that fits in a pocket or as large as a supercomputer that fills a building. Hardware also includes the peripheral devices that work with computers, such as keyboards, external disk drives, and routers. With the rise of the Internet of things, in which anything from home appliances to cars to clothes will be able to receive and transmit data, sensors that interact with computers are permeating the human environment.

Computer software

The hardware needs to know what to do, which is the role of software. The software can be divided into two types: system software and application software. The primary piece of system software is the operating system, such as Windows or iOS, which manages the hardware’s operation. Application software is designed for specific tasks, such as handling a spreadsheet, creating a document, or planning a Web page.

Telecommunications

This component connects the hardware to form a network. Connections can be through wires, such as Ethernet cables or fiber optics, or wireless, such as Wi-Fi. A network can be designed to tie together computers in a specific area, such as an office or a school, through a local area network (LAN). The network is called a vast area network (WAN) if computers are more dispersed. The Internet itself can be considered a network of networks.

Databases & Data Warehouses

This component is where the “material” that the other parts work with resides. A database is where data is collected and can be retrieved by querying it using one or more specific criteria. A data warehouse contains all the data in whatever form an organization needs. Databases and data warehouses have assumed even greater importance in information systems with the emergence of “big data,” a term for the massive amounts of data that can be collected and analyzed.

Human Resources & Procedures

The final and possibly most important component of information systems is the human element: the people that are needed to run the design and the procedures they follow so that the knowledge in the vast databases and data warehouses can be turned into learning that can interpret what has happened in the past and guide future action.
