What is IT Systems?
IT systems (Information Technology systems) are an integrated combination of hardware, software, networks, and processes designed to collect, store, process, and deliver information to support business operations, decision-making, and communication.
How IT Systems Work
IT systems work by:
Capturing Data – via input devices, sensors, applications, or manual entry.
Processing Information – using software, databases, and business logic.
Storing & Securing Data – in servers, cloud platforms, or hybrid environments.
Delivering Outputs – such as reports, dashboards, transactions, or automated actions.
Enabling Connectivity – through networks, APIs, and communication tools for seamless collaboration.
They operate on layered architecture, ensuring hardware (servers, storage), software (applications, OS), and networks (LAN, WAN, cloud) work together efficiently.
