Database management system: software that provides facilities for the organisation and management of a body of information required for a particular app.

Control software: used to supply instructions in order to tell devices how to operate.

Measuring software: used to issue instructions to sensors that record and take measurments of physical quantitites as temperature, pressure, etc

The motherboard is the board which connects every single component of the PC.

GPU's process all the stuff that require large video or image quality. They then send signals through cables to your monitor.

For internal storage there are two options. SSD's and HDD's.
SSD's are much faster than traditional Hard drives because there are no mechanic parts.
