Aries

Known as random access memory, chips are memory where temporary data is stored. By storing data in RAM, the CPU can process data in a shorter period leading faster execution of instructions and tasks assigned to the team.

In general, a numeric value (in GB) is indicated and is the physical size of the data in RAM is capable of storing.

HDD

This hardware stores all data permanently, unlike the RAM that will erase data when the computer is off. Available in two sizes. 5 “(portable) and 3. 5″ (desktop)

In general, a numeric value (in GB) is indicated and is available in different capacities.

A rough calculation

Assuming that a piece of music 4 minutes long, are stored in MP3 format and has a value of 4 MB of hard disk space. 160 GB will be able to store about 40,000 songs!

Graphic card

As mentioned, this card is primarily responsible for the display of images on the monitor.
