An information system is composed of five main components that work together to collect, process, and organize data. These components are:12
- Computer Hardware: The physical technology used to process information, ranging from smartphones and tablets to large supercomputers and peripheral devices like input-output devices.32
- Computer Software: The programs that instruct hardware on how to function, categorized into system software (such as an operating system) and application software designed for specific tasks.12
- Telecommunications: The infrastructure that connects hardware components to form networks, utilizing wired connections like fibre optics or wireless technologies such as Wi-Fi to facilitate data transmission.12
- Databases and Data Warehouses: The storage systems where data is organized and maintained. Databases allow for the retrieval of specific records, while data warehouses store archival data for broader analysis and decision-making.42
- Human Resources and Procedures: The people who operate and manage the system, alongside the established procedures they follow to ensure the system is used effectively and securely.52
