Data organization

Organizations have always had to save and process different data for their operation. Data organization for its subsequent analysis has been one of the priorities for the organizations. Many years ago, computers were not available yet, the data was recorded on paper and stored in filing cabinets. Physical cabinets with drawers, which we consulted when we needed to recover any of these data.

This data organization forced us to have large spaces for storage and required a great effort of registration. It also had many other drawbacks. Always we wanted to access a piece of data, it spent considerable time locating it. Access was exclusive so that if someone was consulting any file of information, it was not available to anyone else. All this without mentioning the limited possibilities available for data processing.

The power supply

All the devices connected to the motherboard, need to be supplied with the electrical current for their operation. The power supply is the component of the computer that fulfils this function.

We take the electrical current from the electric supply network, to which we plug the PC Power Supply, which transforms alternating current into direct current, at suitable voltages for the computer devices. Therefore, although we normally refer to the Power Supply with that name, it does not generate electricity, it is not a source, but a transformer from alternating current to direct current, and from high voltage to low voltage.

Usually, a computer needs a 12-volt direct current to power the motors of devices, such as hard drives, and a 5-volt or 3.3-volt direct current for the different electronic components.
