We present you in a simple infographic, a model of IT systems, composed of hardware, software, communication systems, data systems and human factor.
Hardware
It refers to all the electronic devices that are used in the system to send, receive, store and communicate the information.
Software
It refers to the programs and applications that allow the use of the devices for the management and exchange of information.
