IT is reliant upon items to electronically input, output, process, store, and retrieve data.
A subsystem is a component of a larger system.
In a company, different kinds of subsystems include operational, financial, marketing, human resources, and information technology systems. The operational subsystem focuses on day-to-day activities and processes, while the financial subsystem manages budgets and financial reporting. The marketing subsystem is responsible for promoting products and services, and the human resources subsystem handles recruitment, training, and employee relations. Finally, the information technology subsystem supports all other subsystems by providing necessary technology and data management solutions.
Subsystems can be categorized into several types based on their functions and characteristics. Common types include physical subsystems, which involve tangible components like machinery or hardware; logical subsystems, which focus on data and software processes; and organizational subsystems, which pertain to human elements, such as teams and management structures. Additionally, subsystems may be classified based on their interactions, such as open or closed subsystems, depending on their exchange of information with the external environment.
The list of technologies that comprise what is called the discipline of "Information Technology" is too vast to document. Given the rapid and ever-changing landscape in the IT field, it's even too difficult to document the vast list of what can be considered "the latest technologies."

Typical functional information subsystems in an organization include finance, human resources, marketing, operations, and supply chain management. Each subsystem manages specific types of data and processes relevant to its function, such as financial transactions, employee records, customer interactions, production schedules, and inventory levels. These subsystems often rely on integrated information systems to facilitate communication and data sharing across the organization, enhancing overall efficiency and decision-making.
