Information technology (IT) refers to the systems and tools used to store, process, transmit, and manage digital information. It includes hardware, software, networks, and databases that support modern organizations.
IT professionals install and maintain computer systems, troubleshoot technical problems, manage networks, secure digital infrastructure, and provide technical support to users across an organization.
A computer receives input, processes data through the CPU, stores information in memory or storage, and produces output through monitors, printers, or other devices. Hardware and software work together to execute tasks.
Core components include the CPU, RAM, storage devices, input devices (keyboard, mouse), output devices (monitor, printer), motherboard, and power supply. Each plays a specific role in processing and managing information.
Common IT skills include hardware troubleshooting, networking fundamentals, operating system knowledge, cybersecurity awareness, and communication skills for assisting users and documenting technical solutions.
